@@ # Marty Microservices Framework -**Feature overview.** Marty Microservices Framework (MMF) is designed to meet all of the core needs of a microservice-based system. It bundles an [API gateway](https://github.com/burdettadam/marty-microservices-framework#features) for intelligent routing and load-balancing, [service discovery](https://github.com/burdettadam/marty-microservices-framework#features) via Consul, and centralized [configuration management](https://github.com/burdettadam/marty-microservices-framework#features) with hot-reload. Built-in [event streaming](https://github.com/burdettadam/marty-microservices-framework#features) uses Kafka for asynchronous messaging, while [database integration](https://github.com/burdettadam/marty-microservices-framework#features) provides multi-database support with connection pooling and [distributed caching](https://github.com/burdettadam/marty-microservices-framework#features) via Redis. The framework offers [real-time metrics and profiling](https://github.com/burdettadam/marty-microservices-framework#observability), with Prometheus, Grafana and Jaeger providing metrics, dashboards and distributed tracing. A rich [CLI and project scaffolding](https://github.com/burdettadam/marty-microservices-framework#development-experience) system generates FastAPI, gRPC or hybrid services, manages dependencies and automates Docker/Kubernetes deployment. The [security module](https://github.com/burdettadam/marty-microservices-framework#security) supplies JWT-based auth, OAuth2/OpenID Connect integration, rate limiting, DDoS protection, zero-trust components and certificate management. MMF also includes a comprehensive [test suite](https://github.com/burdettadam/marty-microservices-framework#testing) (unit, integration and e2e), extensive [documentation and guides](https://github.com/burdettadam/marty-microservices-framework/tree/main/docs), [operations templates](https://github.com/burdettadam/marty-microservices-framework/tree/main/devops/kubernetes) for Kubernetes, service-mesh configs, dashboards and CI/CD pipelines, and [sample domain services](https://github.com/burdettadam/marty-microservices-framework/tree/main/examples/demos/petstore_domain) such as order, payment and inventory to illustrate patterns. These features collectively aim to give plugin authors and service teams everything they need out of the box. +**Enterprise-grade Python Microservices Platform** -**Technical stack.** MMF is built with Python 3.10+, using [FastAPI](https://fastapi.tiangolo.com/) for HTTP endpoints and [gRPC](https://grpc.io/) for high-performance RPC, and provides [Jinja-based templates](https://github.com/burdettadam/marty-microservices-framework/tree/main/templates) for scaffolding new services. Service discovery uses [Consul](https://developer.hashicorp.com/consul/docs), while event-driven communication relies on [Kafka](https://kafka.apache.org/); data is persisted in multiple databases (e.g., PostgreSQL) with built-in connection pooling and augmented with a [Redis](https://redis.io/) cache. Observability is handled by [Prometheus](https://prometheus.io/) for metrics, [Grafana](https://grafana.com/) for dashboards and [Jaeger](https://www.jaegertracing.io/) for distributed tracing, all running inside a local or cloud [Kubernetes](https://kubernetes.io/) cluster. The framework’s CLI (based on [Typer](https://typer.tiangolo.com/)) orchestrates code generation, dependency management, Docker builds and Kubernetes deployments, while the security layer integrates JWT and OAuth2/OIDC providers and includes rate-limiting and certificate management. Operations tooling includes [Kubernetes manifests](https://github.com/burdettadam/marty-microservices-framework/tree/main/devops/kubernetes), [service-mesh configuration](https://github.com/burdettadam/marty-microservices-framework/tree/main/docs/architecture), monitoring dashboards and CI/CD pipelines. Together, this stack ensures that MMF can deliver the full set of microservices features listed above with minimal additional setup. +Marty Microservices Framework (MMF) is a "batteries-included" platform designed to accelerate microservices development. It implements **Hexagonal Architecture (Ports and Adapters)** to ensure modularity, testability, and long-term maintainability. -## 📁 Project Structure - -``` -. -├── README.md -├── Makefile -├── pyproject.toml -├── docs/ # Documentation -│ ├── guides/ # Development guides -│ ├── architecture/ # Architecture documentation -│ └── demos/ # Demo documentation & quickstarts -├── src/ # Source code -│ └── marty_msf/ # Main framework package -│ ├── framework/ # Core framework modules -│ ├── cli/ # Command-line interface -│ ├── security/ # Security modules -│ └── observability/ # Monitoring & observability -├── services/ # Service templates & examples -│ ├── fastapi/ # FastAPI service templates -│ ├── grpc/ # gRPC service templates -│ ├── hybrid/ # Hybrid service templates -│ └── shared/ # Shared service components & Jinja assets -├── examples/ # Usage examples -│ ├── demos/ # Demo applications -│ │ ├── order-service/ # Order service demo -│ │ ├── payment-service/ # Payment service demo -│ │ ├── inventory-service/ # Inventory service demo -│ │ └── runner/ # Demo runner scripts -│ └── notebooks/ # Jupyter notebooks for tutorials -├── ops/ # Operations & deployment -│ ├── k8s/ # Kubernetes manifests -│ ├── service-mesh/ # Service mesh configuration -│ ├── dashboards/ # Monitoring dashboards -│ └── ci-cd/ # CI/CD pipelines -├── scripts/ # Utility scripts -│ ├── dev/ # Development scripts -│ └── tooling/ # Build & maintenance tools -├── tests/ # Test suite -│ ├── unit/ # Unit tests -│ ├── integration/ # Integration tests -│ ├── e2e/ # End-to-end tests -│ └── quality/ # Code quality & lint tests -├── tools/ # Development tools -│ └── scaffolding/ # Project generators & templates -└── var/ # Runtime files (gitignored logs, pids, reports) -``` - -## 🚀 Quick Start - Local Development Environment - -### Get Started in 2 Minutes - -```bash -# 1.

-### Phase 2: Expand the Example - -- **Status**: NEXT -- **Goal**: Add more use cases and realistic infrastructure adapters -- **Tasks**: - - Add authorization use cases - - Create database and HTTP adapters - - Implement service-scope plugins - - Connect to platform_core contracts - -### Phase 3: Begin Migration - -- **Status**: PLANNED -- **Goal**: Start moving functionality from existing code to new architecture -- **Approach**: - - Migrate piece by piece with full test coverage - - Keep existing code running during migration - - Move to boneyard only after full replacement - -### Phase 4: Platform Integration - -- **Status**: PLANNED -- **Goal**: Implement cross-cutting concerns and platform plugins -- **Tasks**: - - Complete platform_core contracts - - Implement platform_plugins for mesh, secrets, telemetry - - Cross-service infrastructure setup - -## Key Principles - -### Hexagonal Architecture (Ports & Adapters) - -- **Domain**: Pure business logic, no external dependencies -- **Application**: Use cases that orchestrate domain and external world -- **Infrastructure**: Adapters that implement ports and handle I/O -- **Ports**: Abstract interfaces that define contracts - -### Test-Driven Development (TDD) - -- Domain models driven by unit tests -- Use cases tested in isolation with mocks -- Integration tests verify complete flows -- Contract tests ensure port implementations are correct - -### Bounded Contexts - -- Each service represents a business capability -- Clear boundaries with explicit interfaces -- Independent deployment and scaling -- Domain-specific languages and models - -### Plugin Architecture - -- **Service-scope plugins**: Feature extensions within a service -- **Platform-scope plugins**: Infrastructure provider choices -- Clear plugin contracts and lifecycle management -- Runtime composition and configuration - -## Current Progress - -- ✅ **Boneyard structure** for deprecated code -- ✅ **New directory structure** following hexagonal architecture -- ✅ **Minimal identity service** with complete domain model -- ✅ **Port definitions** for inbound and outbound dependencies -- ✅ **Use case implementation** with proper business logic -- ✅ **Infrastructure adapters** (in-memory for testing) -- ✅ **Comprehensive test suite** (unit, integration, TDD) -- ✅ **Documentation** of architecture and migration strategy - -## Running the Minimal Example - -```bash -# Install dependencies (adjust as needed) -pip install pytest - -# Run all tests for the minimal example -pytest mmf_new/services/identity/tests/ - -# Run specific test types -pytest mmf_new/services/identity/tests/test_domain_models.py -pytest mmf_new/services/identity/tests/test_authentication_usecases.py -pytest mmf_new/services/identity/tests/test_integration.py -``` - -## Next Steps - -1. **Expand the minimal example**: - - Add authorization use cases - - Create realistic database adapters - - Implement HTTP inbound adapters - - Add service-scope plugin examples - -2. **Platform core development**: - - Complete contracts for secrets, telemetry, policy - - Implement plugin loading and lifecycle - - Create contract test framework - -3. **Begin selective migration**: - - Identify high-value, low-risk components to migrate first - - Maintain parallel operation during migration - - Prove each migration with comprehensive tests - -4. **Platform plugin implementation**: - - Service mesh integration (Istio/Linkerd) - - Secret management (Vault/AWS SSM) - - Observability (OpenTelemetry) - -## Why This Approach - -- **De-risk the migration**: Prove architecture before committing -- **Enable parallel development**: Keep existing code working -- **Test-driven quality**: Every component has comprehensive tests -- **Clear progression**: Each phase builds on proven foundations -- **Maintainable code**: Clean boundaries and clear responsibilities diff --git a/TESTING_IMPROVEMENTS.md b/TESTING_IMPROVEMENTS.md new file mode 100644 index 00000000..f6dc8558 --- /dev/null +++ b/TESTING_IMPROVEMENTS.md @@ -0,0 +1,67 @@ +# Testing Improvements & Status Report + +## Status Overview + +We have significantly improved the testing infrastructure and quality assurance processes for the `marty-microservices-framework`. + +### 1.

Moved to Boneyard - -**Migration Date:** November 12, 2025 -**Reason:** Replaced with new hierarchical configuration system in `mmf_new/config/` - -## What Was Moved - -This directory contains the old configuration files that were replaced by the new MMF hexagonal architecture configuration system. - -### Files Moved: -- `base.yaml` - Old base configuration with mixed service and platform concerns -- `development.yaml` - Old development environment configuration -- `production.yaml` - Old production environment configuration -- `testing.yaml` - Old testing environment configuration - -### Migration Destination: - -| Old File | New Location | Improvements | -|----------|-------------|-------------| -| `base.yaml` | `mmf_new/config/base.yaml` | Refactored with clear separation of concerns | -| `development.yaml` | `mmf_new/config/environments/development.yaml` | Environment-specific overrides | -| `production.yaml` | `mmf_new/config/environments/production.yaml` | Enhanced security and production settings | -| `testing.yaml` | `mmf_new/config/environments/testing.yaml` | Optimized for test performance | -| N/A | `mmf_new/config/services/*.yaml` | New service-specific configurations | -| N/A | `mmf_new/config/platform/core.yaml` | New platform-wide configuration | - -## Why These Files Were Replaced - -The old configuration system had several limitations: - -### 🚫 Problems with Old System -1. **Monolithic Structure** - All configurations mixed together -2. **No Service Separation** - One-size-fits-all approach -3. **Limited Secret Management** - Basic environment variable support only -4. **No Platform Configuration** - Cross-cutting concerns mixed with service config -5. **Poor Type Safety** - Dictionary-based access without validation -6. **Inflexible Hierarchy** - Limited override capabilities - -### ✅ New System Benefits -1. **Hierarchical Configuration** - Base → Platform → Environment → Service -2. **Service-Specific Configs** - Each service can have its own configuration -3. **Advanced Secret Management** - Multiple backends with `${SECRET:key}` syntax -4. **Platform Separation** - Clear separation of platform and service concerns -5. **Type-Safe Access** - Structured dataclasses with IDE support -6. **Flexible Overrides** - Deep merging with clear precedence rules - -## Migration Impact - -### Backward Compatibility -- ❌ **Not backward compatible** - New configuration system requires code changes -- ✅ **Migration path provided** - Clear documentation and examples in `mmf_new/config/README.md` -- ✅ **Feature parity** - All old functionality replicated in new system - -### Services Affected -- All services that previously used `config/` files -- Services should be migrated to use new configuration system -- Examples provided for `identity-service` and `api-gateway` -

We could have other implementations, like HardcodedSecretManager (for testing), VaultSecretManager (for a HashCorp Vault integration), etc., without changing the authenticator code – because the authenticator only cares about the ISecretManager interface. Now each of these modules (auth.py, authz.py, secrets.py) is at the same layer in our architecture: they implement the business logic, and all three depend on the lower-layer api definitions. They do not depend on each other. This modularizes the security package. For instance, you can modify how secrets are stored or how authorization is done without touching the authentication module, as long as the interface contracts remain the same. 2.4 Wiring Components Together in a Bootstrap Module After splitting the code, the remaining question is: How do these pieces come together at runtime? Without a dependency injection framework, we will wire the components manually in a designated place. This is often called the composition root of the application – a central place where you assemble the object graph. In our case, we can create a marty_msf.security.bootstrap module (or integrate this into the application startup code) that knows about the concrete classes and composes them. diff --git a/docs/internal_import_analysis.json b/docs/internal_import_analysis.json deleted file mode 100644 index 7192a108..00000000 --- a/docs/internal_import_analysis.json +++ /dev/null @@ -1,2670 +0,0 @@ -{ -

Hexagonal Architecture Example + +This directory contains a **minimal working example** of the new hexagonal architecture (ports and adapters) for the Marty Microservices Framework. It demonstrates the core concepts with a simple identity service that handles authentication. + +## Architecture Overview + +This example follows the hexagonal architecture pattern with clear separation of concerns: + +``` +mmf/services/identity/ +├── domain/ # Pure business logic (no dependencies) +│ ├── models/ # Entities, value objects, domain policies +│ └── contracts/ # Domain-level interfaces (no I/O) +├── application/ # Use cases (orchestrates domain + external world) +│ ├── ports_in/ # Inbound ports (use case interfaces) +│ ├── ports_out/ # Outbound ports (external dependencies) +│ ├── usecases/ # Use case implementations +│ └── policies/ # Application policies (idempotency, etc.) +├── infrastructure/ # Adapters (implements ports) +│ └── adapters/ # Inbound and outbound adapters +├── plugins/ # Service-scope feature plugins +├── platform/ # Wiring to platform_core +└── tests/ # All test types (unit, integration, contract) +``` + +## Key Principles Demonstrated + +### 1. **Ports and Adapters** + +- **Inbound Ports**: `AuthenticatePrincipal` - defines what the service can do +- **Outbound Ports**: `UserRepository`, `EventBus` - defines what the service needs +- **Adapters**: `InMemoryUserRepository`, `InMemoryEventBus` - implement the ports + +### 2. **Dependency Inversion** + +- Domain depends on nothing +- Application depends only on domain and its own port interfaces +- Infrastructure depends on application ports but not the reverse + +### 3. **Test-Driven Development (TDD)** + +- Domain models have comprehensive unit tests +- Use cases have isolated unit tests with mocks +- Integration tests verify the complete flow +- Tests drive the design and ensure quality + +### 4. **Clean Boundaries** + +- No framework code in domain or application layers +- Infrastructure details isolated in adapters +- Clear contracts between layers + +## Domain Model + +The domain contains core business entities: + +- **`UserId`**: Value object for user identification +- **`Credentials`**: Value object for authentication data +- **`Principal`**: Entity representing an authenticated user +- **`AuthenticationResult`**: Result of authentication attempts +- **`AuthenticationStatus`**: Enumeration of possible authentication states + +## Use Cases + +Currently implements one core use case: + +- **`AuthenticatePrincipalUseCase`**: Validates credentials and creates authenticated principals + +## Infrastructure Adapters + +Simple in-memory implementations for testing: + +- **`InMemoryUserRepository`**: Stores users in memory with simple password hashing +- **`InMemoryEventBus`**: Collects events for verification in tests + +## Running Tests + +```bash +# Run all tests +pytest mmf/services/identity/tests/ + +# Run specific test types +pytest mmf/services/identity/tests/test_domain_models.py # Domain unit tests +pytest mmf/services/identity/tests/test_authentication_usecases.py # Use case tests +pytest mmf/services/identity/tests/test_integration.py # Integration tests +``` + +## Migration Strategy + +This minimal example serves as the **template and proving ground** for migrating the existing code: + +### Current State + +- **`mmf/`** - Existing working code with similar structure +- **`mmf/`** - This minimal example +- **`src/marty_msf/`** - Legacy security framework +- **`boneyard/`** - Code to be deprecated (currently empty) + +### Migration Process + +1. **✅ Prove the architecture** - This minimal example demonstrates the pattern +2. **Next: Expand the example** - Add more use cases (authorization, token validation, etc.) +3. **Then: Migrate piece by piece** - Move functionality from `mmf/` and `src/` to the new structure +4. **Finally: Deprecate old code** - Move replaced code to `boneyard/` only after full migration + +### Why This Approach + +- **De-risk the migration** - Prove the architecture works before committing +- **Enable parallel development** - Old code keeps working while new is built +- **Test-driven migration** - Every migrated piece has comprehensive tests +- **Clear progression** - Each step builds on proven foundations + +## Next Steps + +1. **Expand use cases**: Add authorization, token validation, user management +2. **Add real adapters**: Database, HTTP, message queue implementations +3. **Platform integration**: Connect to `platform_core` contracts +4. **Plugin system**: Demonstrate service-scope plugins +5. **Migration execution**: Begin moving functionality from existing code + +## Platform Integration + +Eventually this service will integrate with: + +- **`platform_core/`** - Cross-cutting contracts (secrets, telemetry, policy) +- **`platform_plugins/`** - Operator-scope infrastructure providers +- **`infrastructure/`** - Cross-service infrastructure (gateway, mesh, etc.) +- **`deploy/`** - Deployment manifests and configurations + +This minimal example focuses on the service-level architecture first, then will integrate with the platform concerns. diff --git a/mmf/services/identity/__init__.py b/mmf/services/identity/__init__.py index e69de29b..f832ea82 100644 --- a/mmf/services/identity/__init__.py +++

Hexagonal Architecture Example - -This directory contains a **minimal working example** of the new hexagonal architecture (ports and adapters) for the Marty Microservices Framework. It demonstrates the core concepts with a simple identity service that handles authentication. - -## Architecture Overview - -This example follows the hexagonal architecture pattern with clear separation of concerns: - -``` -mmf_new/services/identity/ -├── domain/ # Pure business logic (no dependencies) -│ ├── models/ # Entities, value objects, domain policies -│ └── contracts/ # Domain-level interfaces (no I/O) -├── application/ # Use cases (orchestrates domain + external world) -│ ├── ports_in/ # Inbound ports (use case interfaces) -│ ├── ports_out/ # Outbound ports (external dependencies) -│ ├── usecases/ # Use case implementations -│ └── policies/ # Application policies (idempotency, etc.) -├── infrastructure/ # Adapters (implements ports) -│ └── adapters/ # Inbound and outbound adapters -├── plugins/ # Service-scope feature plugins -├── platform/ # Wiring to platform_core -└── tests/ # All test types (unit, integration, contract) -``` - -## Key Principles Demonstrated - -### 1. **Ports and Adapters** - -- **Inbound Ports**: `AuthenticatePrincipal` - defines what the service can do -- **Outbound Ports**: `UserRepository`, `EventBus` - defines what the service needs -- **Adapters**: `InMemoryUserRepository`, `InMemoryEventBus` - implement the ports - -### 2. **Dependency Inversion** - -- Domain depends on nothing -- Application depends only on domain and its own port interfaces -- Infrastructure depends on application ports but not the reverse - -### 3. **Test-Driven Development (TDD)** - -- Domain models have comprehensive unit tests -- Use cases have isolated unit tests with mocks -- Integration tests verify the complete flow -- Tests drive the design and ensure quality - -### 4. **Clean Boundaries** - -- No framework code in domain or application layers -- Infrastructure details isolated in adapters -- Clear contracts between layers - -## Domain Model - -The domain contains core business entities: - -- **`UserId`**: Value object for user identification -- **`Credentials`**: Value object for authentication data -- **`Principal`**: Entity representing an authenticated user -- **`AuthenticationResult`**: Result of authentication attempts -- **`AuthenticationStatus`**: Enumeration of possible authentication states - -## Use Cases - -Currently implements one core use case: - -- **`AuthenticatePrincipalUseCase`**: Validates credentials and creates authenticated principals - -## Infrastructure Adapters - -Simple in-memory implementations for testing: - -- **`InMemoryUserRepository`**: Stores users in memory with simple password hashing -- **`InMemoryEventBus`**: Collects events for verification in tests - -## Running Tests - -```bash -# Run all tests -pytest mmf_new/services/identity/tests/ - -# Run specific test types -pytest mmf_new/services/identity/tests/test_domain_models.py # Domain unit tests -pytest mmf_new/services/identity/tests/test_authentication_usecases.py # Use case tests -pytest mmf_new/services/identity/tests/test_integration.py # Integration tests -``` - -## Migration Strategy - -This minimal example serves as the **template and proving ground** for migrating the existing code: - -### Current State - -- **`mmf/`** - Existing working code with similar structure -- **`mmf_new/`** - This minimal example -- **`src/marty_msf/`** - Legacy security framework -- **`boneyard/`** - Code to be deprecated (currently empty) - -### Migration Process - -1. **✅ Prove the architecture** - This minimal example demonstrates the pattern -2. **Next: Expand the example** - Add more use cases (authorization, token validation, etc.) -3. **Then: Migrate piece by piece** - Move functionality from `mmf/` and `src/` to the new structure -4. **Finally: Deprecate old code** - Move replaced code to `boneyard/` only after full migration - -### Why This Approach - -- **De-risk the migration** - Prove the architecture works before committing -- **Enable parallel development** - Old code keeps working while new is built -- **Test-driven migration** - Every migrated piece has comprehensive tests -- **Clear progression** - Each step builds on proven foundations - -## Next Steps - -1. **Expand use cases**: Add authorization, token validation, user management -2. **Add real adapters**: Database, HTTP, message queue implementations -3. **Platform integration**: Connect to `platform_core` contracts -4. **Plugin system**: Demonstrate service-scope plugins -5. **Migration execution**: Begin moving functionality from existing code - -## Platform Integration - -Eventually this service will integrate with: - -- **`platform_core/`** - Cross-cutting contracts (secrets, telemetry, policy) -- **`platform_plugins/`** - Operator-scope infrastructure providers -- **`infrastructure/`** - Cross-service infrastructure (gateway, mesh, etc.) -- **`deploy/`** - Deployment manifests and configurations - -This minimal example focuses on the service-level architecture first, then will integrate with the platform concerns. diff --git a/mmf_new/services/identity/__init__.py b/mmf_new/services/identity/__init__.py deleted file mode 100644 index c54bd998..00000000 --- a/mmf_new/services/identity/__init__.py +++ /dev/null @@ -1 +0,0 @@ -"""Identity service module.""" diff --git a/mmf_new/services/identity/application/__init__.py b/mmf_new/services/identity/application/__init__.py deleted file mode 100644 index 32a95e81..00000000 --- a/mmf_new/services/identity/application/__init__.py +++ /dev/null @@ -1 +0,0 @@ -"""Application layer.""" diff --git a/mmf_new/services/identity/application/ports_in/__init__.py b/mmf_new/services/identity/application/ports_in/__init__.py deleted file mode 100644 index ab81dac5..00000000 --- a/mmf_new/services/identity/application/ports_in/__init__.py +++ /dev/null @@ -1,13 +0,0 @@ -"""Inbound ports for identity service use cases.""" -

-A comprehensive API Gateway implementation built on the Marty microservices framework, providing enterprise-grade features for routing, service discovery, load balancing, and resilience patterns. - -## Features - -### Core Capabilities - -- **Dynamic Service Discovery**: In-memory service registry with extensible backend support - - ⚠️ **Note**: Consul, etcd, and Kubernetes backends are currently stub implementations - - Production deployments should implement real backend connectors as needed -- **Load Balancing**: Multiple strategies including round-robin, least connections, and weighted distribution -- **Circuit Breaker**: Automatic failure detection and recovery -- **Rate Limiting**: Per-IP and per-user request throttling -- **Authentication**: JWT and API key support -- **Response Caching**: Redis-backed caching with configurable TTL -- **Request/Response Transformation**: Middleware for data transformation -- **CORS Support**: Configurable cross-origin resource sharing - -### Monitoring & Observability - -- **Metrics**: Prometheus-compatible metrics collection -- **Distributed Tracing**: Jaeger integration for request tracing -- **Health Checks**: Service and dependency health monitoring -- **Structured Logging**: JSON-formatted logs with correlation IDs - -### Resilience Patterns - -- **Circuit Breakers**: Prevent cascading failures -- **Retries**: Configurable retry policies with exponential backoff -- **Timeouts**: Request-level timeout management -- **Bulkhead Isolation**: Resource isolation for stability - -## Quick Start - -### Prerequisites - -- Python 3.10+ -- Docker (for service discovery backends) -- Redis (for caching) - -### Installation - -1. **Clone and Install Dependencies** - -```bash -git clone -cd api-gateway-service -pip install -e . -``` - -2. **Start Required Services** - -```bash -# Start Consul for service discovery -docker run -d --name consul -p 8500:8500 consul:latest - -# Start Redis for caching -docker run -d --name redis -p 6379:6379 redis:latest -``` - -3. **Configure the Gateway** - -```python -# config.py - Customize for your environment -from config import create_development_config - -config = create_development_config() -# Modify routes, authentication, etc. -``` - -4. **Run the Gateway** - -```bash -python main.py -``` - -The gateway will be available at `http://localhost:8080` - -## Configuration - -### Environment Variables - -```bash -# Service Discovery -CONSUL_HOST=localhost -CONSUL_PORT=8500 -CONSUL_TOKEN=optional-token - -# Authentication -JWT_SECRET=your-jwt-secret-key -JWT_ALGORITHM=HS256 - -# Caching -REDIS_HOST=localhost -REDIS_PORT=6379 - -# Monitoring -JAEGER_ENDPOINT=http://localhost:14268/api/traces -METRICS_PORT=9090 -``` - -### Route Configuration - -```python -from config import RouteDefinition, RateLimitConfig, CircuitBreakerConfig - -# Define custom routes -routes = [ - RouteDefinition( - name="user_api", - path_pattern="/api/v1/users/**", - target_service="user-service", - methods=["GET", "POST", "PUT", "DELETE"], - require_auth=True, - rate_limit=RateLimitConfig(requests_per_second=100), - circuit_breaker=CircuitBreakerConfig(failure_threshold=5), - enable_caching=True, - cache_ttl=300 - ) -] -``` - -## API Endpoints - -### Core Gateway Endpoints - -- `GET /health` - Gateway health status -- `GET /metrics` - Prometheus metrics -- `GET /routes` - Configured routes summary -- `GET /services` - Discovered services -- `GET /services/{service_name}` - Service instances - -### Service Routing - -All configured routes are automatically handled: - -- `/{route_pattern}` - Routed to target services -- Authentication, rate limiting, and circuit breaking applied per route - -## Service Discovery - -### Current Implementation - -The gateway currently uses an in-memory service registry for development and testing: - -```python -service_discovery = ServiceDiscoveryConfig( - type=ServiceDiscoveryType.IN_MEMORY, - health_check_interval=30 -) -``` - -### Future Backend Support (Stub Implementations) - -⚠️ **Development Status**: The following backends have placeholder implementations: - -```python -# Consul integration (stub - requires implementation) -service_discovery = ServiceDiscoveryConfig( - type=ServiceDiscoveryType.CONSUL, - consul_host="localhost", - consul_port=8500, - health_check_interval=30 -) - -# Kubernetes integration (stub - requires implementation) -service_discovery = ServiceDiscoveryConfig( - type=ServiceDiscoveryType.KUBERNETES, - namespace="default", - health_check_interval=30 -) -``` - -**Note**: For production use with external service discovery backends, you'll need to implement the actual client connections to replace the current mock implementations. - -### Service Registration - -Services register themselves with metadata: - -```python -await discovery_manager.register_service(ServiceInstance( - service_name="user-service", - instance_id="user-001", - endpoint="http://user-service:8080", - metadata={ - "version": "1.0.0", - "environment": "production" - } -)) -``` - -## Load Balancing - -### Strategies - -- **Round Robin**: Equal distribution across instances -- **Least Connections**: Route to instance with fewest active connections -- **Weighted Round Robin**: Distribution based on instance weights -- **Random**: Random selection -- **Consistent Hash**: Hash-based routing for session affinity - -### Configuration - -```python -RouteDefinition( - name="api_route", - load_balancing=LoadBalancingStrategy.LEAST_CONNECTIONS, - # ... other config -) -``` - -## Authentication - -### JWT Authentication - -```python -auth = AuthConfig( - type=AuthenticationType.JWT, - secret_key="your-secret", - algorithm="HS256" -) -``` - -### API Key Authentication - -```python -auth = AuthConfig( - type=AuthenticationType.API_KEY, - header_name="X-API-Key" -) -``` - -## Rate Limiting - -### Per-Route Configuration - -```python -rate_limit = RateLimitConfig( - requests_per_second=100.0, - burst_size=200, - window_size=60, - enable_per_ip=True, - enable_per_user=True -) -``` - -### Global Defaults - -Set default rate limits in the main configuration. - -## Circuit Breaker - -### Configuration - -```python -circuit_breaker = CircuitBreakerConfig( - failure_threshold=5, - timeout_seconds=30, - half_open_max_calls=3, - min_request_threshold=20 -) -``` - -### States - -- **Closed**: Normal operation -- **Open**: Failing fast, requests rejected -- **Half-Open**: Testing recovery - -## Caching - -### Response Caching - -```python -caching = CachingConfig( - enabled=True, - default_ttl=300, - redis_host="localhost", - redis_port=6379 -) -``` - -### Cache Keys - -Automatic cache key generation based on: - -- Request path and method -- Query parameters -- User context (optional) - -## Monitoring - -### Metrics - -Available metrics include: - -- Request count and rate -- Response time percentiles -- Error rates by service -- Circuit breaker states -- Cache hit/miss ratios - -### Health Checks - -```bash -# Gateway health -curl http://localhost:8080/health - -# Service discovery health -curl http://localhost:8080/services -``` - -### Distributed Tracing - -Automatic trace generation with: - -- Request ID correlation -- Service-to-service tracing -- Performance analysis - -## Development - -### Running Tests - -```bash -# Install dev dependencies -pip install -e .[dev] - -# Run tests -pytest - -# Run with coverage -pytest --cov=src --cov-report=html -``` - -### Code Quality - -```bash -# Format code -black . - -# Lint code -ruff check . - -# Type checking -mypy . -``` - -## Deployment - -### Docker -

Version Strategy Selection - -- **URL Path**: Most visible, cache-friendly -- **Header**: Clean URLs, requires client modification -- **Query Parameter**: Simple implementation, less clean -- **Media Type**: RESTful, complex client implementation - -### 2. Contract Design - -```python -# Good: Backward compatible changes -{ - "type": "object", - "properties": { - "id": {"type": "integer"}, - "name": {"type": "string"}, - "email": {"type": "string"} # Added optional field - }, - "required": ["id", "name"] # No new required fields -} - -# Bad: Breaking changes -{ - "type": "object", - "properties": { - "id": {"type": "integer"}, - "full_name": {"type": "string"} # Renamed field - }, - "required": ["id", "full_name"] # New required field -} -``` - -### 3. Version Lifecycle - -1. **Draft**: Development version -2. **Stable**: Production-ready version -3. **Deprecated**: Marked for removal, still supported -4. **Retired**: No longer supported - -### 4. Consumer Testing - -```python -# Include comprehensive test cases -test_cases = [ - { - "name": "Get user - success", - "path": "/users/1", - "method": "GET", - "expectations": {"status_code": 200} - }, - { - "name": "Get user - not found", - "path": "/users/999999", - "method": "GET", - "expectations": {"status_code": 404} - }, - { - "name": "Get user - invalid ID", - "path": "/users/invalid", - "method": "GET", - "expectations": {"status_code": 400} - } -] -``` - -## Troubleshooting - -### Common Issues - -1. **Contract Validation Failures** - - ```bash - # Check contract registry - curl http://localhost:8060/api/contracts/user-service - - # Validate specific endpoint - curl -X POST http://localhost:8060/api/test-contracts/user-service/v1 - ``` - -2. **Version Detection Problems** - - ```python - # Debug version extraction - version = version_extractor.extract_version(request) - logger.info(f"Extracted version: {version}") - ``` - -3. **Performance Issues** - - ```bash - # Check metrics - curl http://localhost:8060/metrics | grep contract - - # Monitor cache usage - redis-cli info stats - ``` - -## Contributing - -1. Follow semantic versioning for API changes -2. Include comprehensive contract tests -3. Update documentation for new features -4. Monitor compatibility impact -5.

Always Use Transactions for Writes -```python -# Good -with db_manager.get_transaction() as session: - entity = entity_repo.create(session=session, name="Test") - attribute_repo.create(session=session, entity_id=entity.id, ...) - -# Avoid -with db_manager.get_session() as session: - entity = entity_repo.create(session=session, name="Test") # No auto-commit -``` - -### 2. Use Repository Pattern -```python -# Good -entity = entity_repo.get_by_id(session, entity_id) - -# Avoid direct SQLAlchemy queries -entity = session.query({{service_class}}Entity).filter(...).first() -``` - -### 3. Enable Audit Logging -```python -# Log all changes in service layer -audit_repo.log_change( - session=session, - entity_id=entity.id, - entity_type="{{service_class}}Entity", - action="CREATE", - new_values={"name": entity.name}, - user_id=get_user_id(context), - session_id=get_session_id(context) -) -``` - -### 4. Handle Soft Deletes -```python -# Default to soft delete -entity_repo.delete(session, entity_id, soft_delete=True) - -# Use include_deleted when needed -entity = entity_repo.get_by_id(session, entity_id, include_deleted=True) -``` - -### 5. Use Pagination for Large Results -```python -# Good -entities = entity_repo.get_all(session, skip=0, limit=100) - -# Avoid -entities = entity_repo.get_all(session) # Could return millions -``` - -## Monitoring - -The service includes comprehensive health checks: - -```python -# Database connectivity -health = await db_manager.health_check() - -# Connection pool status -info = db_manager.get_connection_info() - -# Migration status -migration_manager = get_migration_manager() -current_rev = migration_manager.get_current_revision() -head_rev = migration_manager.get_head_revision() -``` - -## Security - -- All queries use parameterized statements (SQLAlchemy ORM) -- Connection pooling prevents connection exhaustion -- Audit logging tracks all data changes -- Soft deletes prevent accidental data loss -- Transaction isolation prevents race conditions - -## Performance - -- Connection pooling for database efficiency -- Indexed columns for fast queries -- Pagination to limit result sets -- Optimistic locking to prevent conflicts -- Query timeout prevention -- Pool overflow handling diff --git a/services/shared/database_service/alembic.ini.j2 b/services/shared/database_service/alembic.ini.j2 deleted file mode 100644 index 46080932..00000000 --- a/services/shared/database_service/alembic.ini.j2 +++ /dev/null @@ -1,84 +0,0 @@ -# Database migrations for {{service_name}} - -[alembic] -# Path to migration scripts -script_location = src/{{service_package}}/app/alembic - -# Template used to generate migration files -file_template = %%(year)d%%(month).2d%%(day).2d_%%(hour).2d%%(minute).2d_%%(rev)s_%%(slug)s - -# sys.path path, will be prepended to sys.path if present. -prepend_sys_path = . - -# Timezone to use when rendering the date within the migration file -# as well as the filename. -timezone = UTC - -# Max length of characters to apply to the "slug" field -truncate_slug_length = 40 - -# Set to 'true' to run the environment during -# the 'revision' command, regardless of autogenerate -revision_environment = false - -# Set to 'true' to allow .pyc and .pyo files without -# a source .py file to be detected as revisions in the -# versions/ directory -sourceless = false - -# Version path separator; As mentioned above, this is the character used to split -# version_locations.

-{{- if include_database }} - -## Database Architecture - -This service follows Marty's enterprise database patterns for service isolation and clean architecture: - -### Service-Specific Database Isolation - -Each service uses its own dedicated database following the naming convention: - -- Database name: `{service_name}_db` -- Automatic configuration based on `SERVICE_NAME` environment variable -- No direct GORM connections - all access through DatabaseManager - -### Database Abstraction Layer - -The service uses Marty's database framework patterns: - -#### DatabaseManager (Singleton) - -- Thread-safe singleton implementation -- Manages GORM connection and health checks -- Provides service-specific database isolation -- Handles connection lifecycle and recovery - -#### Configuration Management - -- Environment-based configuration with validation -- Service-specific database naming -- Connection pool settings -- Health check intervals - -### Usage Example - -```go -package main - -import ( - "{{ module_name }}/internal/database" - "{{ module_name }}/internal/config" - "{{ module_name }}/internal/logger" -) - -// Get singleton instance -dbManager, err := database.GetInstance("my-service", cfg, log) -if err != nil { - log.Fatal("Failed to initialize database", err) -} - -// Get GORM DB instance -db := dbManager.GetDB() - -// Use GORM for operations -var users []User -db.Find(&users) - -// Health check -if err := dbManager.HealthCheck(); err != nil { - log.Error("Database health check failed", err) -} -``` - -### Environment Variables - -```env -SERVICE_NAME={{ service_name }} -DATABASE_URL=postgresql://user:password@localhost:5432/{{ service_name }}_db -DATABASE_POOL_MAX_OPEN_CONNS=25 -DATABASE_POOL_MAX_IDLE_CONNS=5 -DATABASE_CONN_MAX_LIFETIME=300s -``` -

-### Adding New Routes - -1. Create handler functions in `internal/handlers/` -2. Add routes in `internal/app/app.go` in the `setupRoutes()` method -3. Add middleware if needed in `internal/middleware/` - -### Database Migrations - -{{- if include_database }} -Database migrations should be handled in `internal/database/migrations.go` or using a dedicated migration tool. -{{- else }} -Not applicable - database support not included. -{{- endif }} - -## Monitoring - -The service exposes several monitoring endpoints: - -- **Health Check**: `/health` - Service health status -- **Metrics**: `/metrics` - Prometheus metrics -- **Request IDs**: Every request gets a unique ID for tracing - -### Key Metrics - -- `http_requests_total` - Total number of HTTP requests -- `http_request_duration_seconds` - Request duration histogram - -## Security - -The service implements several security best practices: - -- **JWT Authentication** (if enabled) -- **CORS** with configurable origins -- **Rate Limiting** to prevent abuse -- **Security Headers** (XSS protection, frame options, etc.) -- **Input Validation** using Gin validators -- **Secure defaults** in production mode - -## Deployment - -### Docker Compose - -```yaml -version: '3.8' -services: - {{ service_name }}: - build: . - ports: - - "{{ port }}:{{ port }}" - environment: - - ENVIRONMENT=production - - LOG_LEVEL=info - {{- if include_database }} - depends_on: - - postgres - - postgres: - image: postgres:15 - environment: - POSTGRES_DB: {{ service_name }} - POSTGRES_USER: postgres - POSTGRES_PASSWORD: password - {{- endif }} - {{- if include_redis }} - - redis: - image: redis:7-alpine - {{- endif }} -``` - -### Kubernetes - -Use the provided Kubernetes manifests or Helm charts for deployment. - -## Contributing - -1.

-{% if include_database %} - -## Database Architecture - -This service follows Marty's enterprise database patterns for service isolation and clean architecture: - -### Service-Specific Database Isolation - -Each service uses its own dedicated database following the naming convention: - -- Database name: `{service_name}_db` -- Automatic configuration based on `SERVICE_NAME` environment variable -- No direct database connections - all access through DatabaseManager - -### Database Abstraction Layer - -The service uses Marty's database framework patterns: - -#### DatabaseManager (Singleton) - -- Manages connection pooling and health checks -- Provides service-specific database isolation -- Handles connection lifecycle and error recovery - -#### BaseRepository Pattern - -- Provides standard CRUD operations -- Transaction management and rollback support -- Type-safe database operations -- Consistent error handling - -#### Configuration Management - -- Environment-based configuration -- Service-specific database naming -- Connection pool settings -- Health check intervals - -### Usage Example - -```typescript -import { DatabaseManager } from './database'; - -// Get singleton instance -const dbManager = DatabaseManager.getInstance(); - -// Use repository pattern -const userRepo = dbManager.getRepository('users'); -const users = await userRepo.findAll(); - -// Transaction support -await dbManager.transaction(async (trx) => { - await userRepo.create(userData, trx); - await auditRepo.log(auditData, trx); -}); -``` - -### Environment Variables - -```env -SERVICE_NAME={{ service_name }} -DATABASE_URL=postgresql://user:password@localhost:5432/{{ service_name }}_db -DATABASE_POOL_MIN=2 -DATABASE_POOL_MAX=10 -DATABASE_TIMEOUT=30000 -``` - -{% endif %} - -## Monitoring - -### Health Checks - -The service provides comprehensive health checks at `/health`: - -```json -{ - "status": "healthy", - "timestamp": "2023-10-09T12:00:00.000Z", - "uptime": 3600, - "memory": { - "used": "45.2 MB", - "free": "982.8 MB" - },{% if include_database %} - "database": "connected",{% endif %}{% if include_redis %} - "redis": "connected",{% endif %} - "version": "1.0.0" -} -``` - -### Metrics - -Prometheus metrics are exposed at `/metrics`: - -- `http_request_duration_seconds` - Request duration histogram -- `http_requests_total` - Total request counter -- `http_request_errors_total` - Error counter -- `nodejs_*` - Node.js runtime metrics - -## Security - -### Built-in Security Features - -- **Helmet.js** - Security headers -- **CORS** - Cross-origin resource sharing -- **Rate Limiting** - Request rate limiting -- **Input Validation** - Request validation{% if include_auth %} -- **JWT Authentication** - Secure token authentication{% endif %} -- **Error Handling** - Secure error responses - -### Security Headers - -The service automatically sets security headers: - -- Content Security Policy -- HSTS (HTTP Strict Transport Security) -- X-Frame-Options -- X-Content-Type-Options -- Referrer-Policy - -## Docker - -### Build Image - -```bash -docker build -t {{ service_name }} . -``` - -### Run Container - -```bash -docker run -p {{ port }}:{{ port }} {{ service_name }} -``` - -### Docker Compose - -```yaml -version: '3.8' -services: - {{ service_name }}: - build: . - ports: - - "{{ port }}:{{ port }}" - environment: - - NODE_ENV=production{% if include_database %} - - DATABASE_URL=postgresql://user:password@db:5432/{{ service_name }}{% endif %}{% if include_redis %} -

-# Setup middleware -setup_fastapi_audit_middleware(app, config) -``` - -Automatically logs: - -- HTTP requests and responses -- Authentication events -- Slow requests -- Security anomalies -- Error conditions - -### gRPC Interceptor - -```python -from framework.audit import setup_grpc_audit_interceptor - -server = grpc.server(futures.ThreadPoolExecutor(max_workers=10)) -setup_grpc_audit_interceptor(server, config) -``` - -## Search and Analytics - -### Event Search - -```python -# Search by criteria -async for event in audit_logger.search_events( - event_type=AuditEventType.API_REQUEST, - user_id="user123", - start_time=datetime.now() - timedelta(hours=24), - limit=100 -): - print(f"Event: {event.action} at {event.timestamp}") -``` - -### Statistics - -```python -stats = await audit_logger.get_audit_statistics( - start_time=datetime.now() - timedelta(days=7) -) - -print(f"Total events: {stats['total_events']}") -print(f"Security events: {stats['security_events']}") -print(f"Event breakdown: {stats['event_counts']}") -``` - -## Security Features - -### Encryption - -Sensitive data is automatically encrypted using AES-256: - -```python -# Sensitive fields are encrypted -builder.sensitive_detail("ssn", "123-45-6789") -builder.sensitive_detail("credit_card", "4111-1111-1111-1111") -``` - -### Anomaly Detection - -Built-in detection for: - -- Multiple authentication failures -- Large data exports -- Unusual access patterns -- Rate limit violations -- Suspicious IP addresses - -### Access Control - -Audit logs are protected with: - -- File permissions (600) -- Database access controls -- Encrypted sensitive fields -- Immutable logging options - -## Compliance - -### GDPR Compliance - -```python -# Data subject access -events = audit_logger.search_events(user_id="subject123") - -# Data retention -await audit_logger.cleanup_old_events(older_than_days=365) - -# Privacy events -await audit_logger.log_system_event( - AuditEventType.PRIVACY_ACCESS, - "Data subject access request processed", - details={"subject_id": "user123", "data_exported": True} -) -``` - -### SOX Compliance - -```python -# Financial transaction auditing -await audit_logger.log_data_event( - AuditEventType.TRANSACTION, - resource_type="financial_record", - resource_id="txn-789", - action="create", - user_id="accountant123", - changes={"amount": 1000.00, "account": "revenue"} -) -``` - -### HIPAA Compliance - -```python -# Healthcare data access -await audit_logger.log_data_event( - AuditEventType.DATA_ACCESS, - resource_type="patient_record", - resource_id="patient-456", - action="view", - user_id="doctor123", - changes={"fields_accessed": ["diagnosis", "treatment"]} -) -``` - -## Performance - -### Asynchronous Logging - -```python -config.async_logging = True -config.flush_interval_seconds = 30 -``` - -Benefits: - -- Non-blocking event logging -- Batch processing -- Queue management -- Background flushing - -### Batching - -```python -config.batch_size = 100 -``` - -Features: - -- Efficient database writes -- Reduced I/O operations -- Configurable batch sizes -- Automatic flushing - -### Sampling - -```python -middleware_config.sample_rate = 0.1 # Log 10% of requests -``` - -## Error Handling - -The framework provides robust error handling: - -- **Graceful Degradation**: Continues operation if destinations fail -- **Error Isolation**: Destination failures don't affect others -- **Retry Logic**: Automatic retries for transient failures -- **Fallback Logging**: Standard logging for framework errors - -## Best Practices - -### 1. Service Context - -Always provide comprehensive service context: - -```python -context = AuditContext( - service_name="payment-service", - service_version="1.2.3", - environment="production", - node_id="us-west-2-node-01" -) -``` - -### 2. Structured Events - -Use structured event builders for consistency: - -```python -event = (builder - .event_type(AuditEventType.BUSINESS_LOGIC) - .message("Order processed") - .user(user_id) - .resource("order", order_id) - .build()) -``` - -### 3. Sensitive Data - -Mark sensitive data for encryption: - -```python -builder.sensitive_detail("payment_token", token) -``` - -### 4. Performance - -Configure for your environment: - -```python -# High-throughput service -config.async_logging = True -config.batch_size = 500 -config.flush_interval_seconds = 10 - -# Low-latency service -config.async_logging = False -config.min_severity = AuditSeverity.MEDIUM -``` - -### 5. Monitoring - -Monitor audit system health: - -```python -stats = await audit_logger.get_audit_statistics() -if stats['error_events'] > threshold: - # Alert operations team -``` - -## Integration Examples - -See the `examples.py` file for comprehensive integration examples including: - -- Basic audit logging setup -- FastAPI integration -- Database integration -- Performance testing -- Compliance scenarios -- Custom event building - -## Dependencies - -Required packages: - -- `cryptography` - For encryption features -- `sqlalchemy` - For database destinations -- `fastapi` - For FastAPI middleware (optional) -- `grpc` - For gRPC interceptor (optional) -

-```python -# pytest.ini or pyproject.toml -[tool.pytest.ini_options] -testpaths = ["tests", "src/framework/testing/examples.py"] -markers = [ - "unit: mark test as unit test", - "integration: mark test as integration test", - "performance: mark test as performance test", - "slow: mark test as slow test", -] -``` - -### Running Tests - -```bash -# Run all tests -pytest - -# Run only unit tests -pytest -m unit - -# Run integration tests -pytest -m integration - -# Run performance tests (slow) -pytest -m performance --run-slow - -# Run specific test file -pytest tests/test_user_service.py - -# Run with coverage -pytest --cov=src/framework --cov-report=html -``` - -### Test Environment Variables - -```bash -# Set test database URL (defaults to in-memory SQLite) -export TEST_DATABASE_URL="sqlite+aiosqlite:///:memory:" - -# Set logging level for tests -export TEST_LOG_LEVEL="WARNING" - -# Enable/disable test features -export SKIP_INTEGRATION_TESTS="false" -export SKIP_PERFORMANCE_TESTS="true" -``` - -## Advanced Features - -The framework also includes advanced testing capabilities: - -### Contract Testing - -```python -from framework.testing import ContractBuilder, verify_contracts_for_provider - -# Create consumer-driven contract -contract = (ContractBuilder("user-frontend", "user-service") - .interaction("Get user by ID") - .with_request("GET", "/users/123") - .will_respond_with(200, body={"id": 123, "name": "John"}) - .build()) - -# Verify provider compliance -await verify_contracts_for_provider("user-service", "http://localhost:8080") -``` - -### Chaos Engineering - -```python -from framework.testing import create_service_kill_experiment, ChaosTestCase - -# Create chaos experiment -experiment = create_service_kill_experiment("user-service", duration=60) -chaos_test = ChaosTestCase(experiment) - -# Run chaos test -await chaos_test.execute() -``` - -### Load Testing - -```python -from framework.testing import create_load_test - -# Create load test -load_test = create_load_test( - name="User API Load Test", - url="http://localhost:8080/api/users", - users=50, - duration=120, - criteria={ - "max_response_time": 1.0, - "min_requests_per_second": 100, - "max_error_rate": 0.05, - } -) - -# Execute load test -results = await load_test.execute() -``` - -### Test Automation - -```python -from framework.testing import setup_basic_test_automation - -# Setup automated testing -orchestrator = setup_basic_test_automation( - test_dirs=["./tests"], - environments=["development", "testing", "staging"] -) - -# Run automated test suite -await orchestrator.run_continuous_testing() -``` - -## Best Practices - -### 1. Test Organization - -``` -tests/ -├── unit/ -│ ├── test_user_service.py -│ ├── test_auth_service.py -│ └── ... -├── integration/ -│ ├── test_user_api_integration.py -│ ├── test_database_integration.py -│ └── ... -├── performance/ -│ ├── test_load.py -│ ├── test_stress.py -│ └── ... -└── e2e/ - ├── test_user_journey.py - └── ... -``` - -### 2. Service Testing Pattern - -```python -class TestServicePattern(AsyncTestCase, ServiceTestMixin): - """Standard pattern for service testing.""" - - async def setup_method(self): - """Setup with standard dependencies.""" - await self.setup_async_test() - - # Create standard test environment - config = self.setup_service_test_environment("my_service") - dependencies = self.create_mock_dependencies("my_service") - - # Initialize service - self.service = MyService(**dependencies) - - @unit_test - async def test_health_check(self): - """Standard health check test.""" - health = await self.service.health_check() - self.assert_standard_service_health(health) - - @unit_test - async def test_metrics(self): - """Standard metrics test.""" - metrics = await self.service.get_metrics() - self.assert_standard_metrics_response(metrics) -``` - -### 3. Event Testing Pattern - -```python -class TestEventPattern(AsyncTestCase): - """Standard pattern for event testing.""" - - @unit_test - async def test_event_flow(self): - """Test complete event flow.""" - # Setup event collectors - collectors = { - "user": TestEventCollector(["user.created", "user.updated"]), - "audit": TestEventCollector(["audit.log"]), - } - - for collector in collectors.values(): - await self.test_event_bus.subscribe(collector) - - # Execute operation - await self.service.create_user("test@example.com", "Test User") - - # Verify events - collectors["user"].assert_event_published("user.created") - collectors["audit"].assert_event_published("audit.log") -``` - -### 4. Database Testing Pattern - -```python -class TestDatabasePattern(AsyncTestCase): - """Standard pattern for database testing.""" - - @integration_test - async def test_with_transaction(self): - """Test with database transaction.""" - async with self.test_db.get_session() as session: - # Create test data - user = User(email="test@example.com", name="Test User") - session.add(user) - await session.commit() - - # Test operations - result = await self.repository.get_by_email("test@example.com", session) - assert result is not None - assert result.email == "test@example.com" -``` - -## Troubleshooting - -### Common Issues - -1. **Async test setup issues**: Ensure `await self.setup_async_test()` is called in `setup_method()` - -2. **Event collection not working**: Check that event collector is subscribed before publishing events - -3. **Database tests failing**: Verify that `test_database` fixture is used and tables are created - -4. **Performance tests timing out**: Increase timeout values or reduce test load - -5. **Import errors**: Ensure all dependencies are installed: `pip install pytest pytest-asyncio` - -### Debugging - -```python -# Enable debug logging in tests -import logging -logging.getLogger("src.framework").setLevel(logging.DEBUG) - -# Add debug assertions -assert len(self.event_collector.events) > 0, f"No events collected, available: {self.event_collector.events}" - -# Use wait_for_condition for async operations -await wait_for_condition( - lambda: len(self.event_collector.events) >= expected_count, - timeout=5.0, - interval=0.1, -) -``` - -This testing infrastructure provides a solid foundation for comprehensive microservices testing while maintaining DRY principles and enterprise-grade capabilities. diff --git a/src/marty_msf/framework/testing/__init__.py b/src/marty_msf/framework/testing/__init__.py deleted file mode 100644 index 30551a8b..00000000 --- a/src/marty_msf/framework/testing/__init__.py +++ /dev/null @@ -1,460 +0,0 @@ -""" -DRY Testing Infrastructure for Marty Microservices Framework. -

-## 🔧 Integration Examples - -### Complete FastAPI Service - -```python -from fastapi import FastAPI -from marty_msf.framework.monitoring import ( - initialize_monitoring, - initialize_custom_metrics, - setup_fastapi_monitoring, - MonitoringMiddlewareConfig, - DatabaseHealthCheck, - AlertRule, - AlertLevel -) - -app = FastAPI() - -@app.on_event("startup") -async def startup(): - # Initialize monitoring - monitoring_manager = initialize_monitoring( - service_name="user-service", - use_prometheus=True, - jaeger_endpoint="http://jaeger:14268/api/traces" - ) - - # Initialize custom metrics - custom_metrics = initialize_custom_metrics() - - # Add health checks - monitoring_manager.add_health_check( - DatabaseHealthCheck("database", get_db_session) - ) - - # Add alert rules - custom_metrics.add_alert_rule( - AlertRule( - name="high_error_rate", - metric_name="error_rate", - condition=">", - threshold=5.0, - level=AlertLevel.CRITICAL, - description="User service error rate too high" - ) - ) - - # Setup monitoring middleware - config = MonitoringMiddlewareConfig() -

custom_metrics = get_custom_metrics_manager() - if custom_metrics: - await custom_metrics.stop_monitoring() -``` - -## 📋 Best Practices - -### 1. Metric Naming - -Follow Prometheus naming conventions: - -```python -# Good -user_registrations_total -order_processing_duration_seconds -payment_success_rate - -# Avoid -userRegistrations -Order-Processing-Time -payment_success_percentage -``` - -### 2. Label Usage - -Use labels for high-cardinality dimensions: - -```python -# Good - finite set of values -labels={"method": "GET", "status": "200", "endpoint": "/api/users"} - -# Avoid - infinite cardinality -labels={"user_id": "12345", "request_id": "abcd-1234"} -``` - -### 3. Health Check Design - -```python -# Design health checks to be: -# - Fast (< 5 seconds) -# - Reliable -# - Indicative of service health - -class GoodHealthCheck(HealthCheck): - async def check(self) -> HealthCheckResult: - try: - # Quick, essential check - await db.execute("SELECT 1") - return HealthCheckResult( - name=self.name, - status=HealthStatus.HEALTHY, - message="Database accessible" - ) - except Exception as e: - return HealthCheckResult( - name=self.name, - status=HealthStatus.UNHEALTHY, - message=f"Database check failed: {str(e)}" - ) -``` - -### 4. Alert Rule Design - -```python -# Effective alert rules: -# - Have clear thresholds -# - Include context -# - Are actionable - -AlertRule( - name="database_connection_failure", - metric_name="database_health_status", - condition="==", - threshold=0, # 0 = unhealthy, 1 = healthy - level=AlertLevel.CRITICAL, - description="Database connection failed - immediate action required", - window_minutes=2, # Short window for critical issues - evaluation_interval_seconds=30 -) -``` - -## 📦 Dependencies - -Required packages: - -```bash -# Core monitoring -pip install prometheus_client - -# Distributed tracing (optional) -pip install opentelemetry-api opentelemetry-sdk -pip install opentelemetry-exporter-jaeger-thrift -pip install opentelemetry-instrumentation-fastapi -pip install opentelemetry-instrumentation-grpc - -# FastAPI integration (optional) -pip install 'fastapi[all]' - -# Redis health checks (optional) -pip install aioredis - -# Database health checks (optional) -pip install sqlalchemy -``` - -## 🚀 Performance - -The monitoring framework is designed for production use: - -- **Low Overhead**: < 1ms per request for metric collection -- **Asynchronous**: Non-blocking metric recording -- **Efficient**: Batch processing for database operations -- **Scalable**: Supports high-throughput services -- **Memory Efficient**: Configurable metric buffers - -## 📖 Examples - -See `examples.py` for comprehensive usage examples: - -- Basic monitoring setup -- Custom business metrics -- FastAPI integration -- Advanced health checks -- Performance monitoring -- Alerting and notifications - -Run examples: - -```bash -python -m framework.monitoring.examples -``` - -## 🔗 Integration with Existing Tools - -### Grafana Dashboards - -Use Prometheus metrics with Grafana: - -``` -- Request rate: rate(microservice_requests_total[5m]) -- Error rate: rate(microservice_errors_total[5m]) / rate(microservice_requests_total[5m]) -- Response time: histogram_quantile(0.95, microservice_request_duration_seconds_bucket) -``` - -### Alertmanager - -Configure Prometheus Alertmanager rules: - -```yaml -groups: -- name: microservice_alerts - rules: - - alert: HighErrorRate - expr: rate(microservice_errors_total[5m]) / rate(microservice_requests_total[5m]) > 0.05 - labels: - severity: critical - annotations: - summary: "High error rate detected" -``` - -This monitoring framework provides enterprise-grade observability for your microservices, enabling you to track performance, detect issues, and maintain service reliability. diff --git a/src/marty_msf/observability/monitoring/__init__.py b/src/marty_msf/observability/monitoring/__init__.py deleted file mode 100644 index e14460ba..00000000 --- a/src/marty_msf/observability/monitoring/__init__.py +++ /dev/null @@ -1,133 +0,0 @@ -""" -Enhanced Monitoring and Observability Framework -
