+# Running Unit Tests for Agent365-nodejs SDK
+
+---
+
+## Prerequisites
+
+1. **Node.js 18+**: `node --version`
+2. **pnpm**: `npm install -g pnpm`
+3. **Dependencies**: `pnpm install` (from repository root)
+4. **Build packages**: `pnpm build` (required before running tests)
+
+---
+
+## Test Structure
+
+```plaintext
+tests/
+├── runtime/                      # Runtime tests
+├── observability/                # Observability tests
+├── tooling/                      # Tooling tests
+├── notifications/                # Notifications tests
+└── all-packages-coverage.test.ts # Ensures all packages appear in coverage reports
+```
+
+---
+
+## Running Tests
+
+### Command Line
+
+```powershell
+# From repository root
+pnpm test
+
+# From tests directory
+cd tests
+pnpm test                              # All tests
+pnpm test:verbose                      # Verbose output
+pnpm test:watch                        # Watch mode
+
+# Run specific test file
+pnpm test -- runtime/power-platform-api-discovery.test.ts
+
+# Additional options
+pnpm test -- --testPathPattern=observability
+pnpm test -- --testNamePattern="should return"
+pnpm test -- --bail                    # Stop on first failure
+pnpm test -- --onlyFailures            # Re-run failed tests only
+```
+
+### VS Code Test Explorer (Optional)
+
+1. Install Jest extension (Orta.vscode-jest)
+2. Click beaker icon or `Ctrl+Shift+P` → "Test: Focus on Test Explorer View"
+3. Click play button to run tests or right-click → "Debug Test"
+
+---
+
+## Coverage Reports
+
+```powershell
+cd tests
+
+# Generate coverage reports
+pnpm test:coverage                     # All formats (HTML, LCOV, Cobertura)
+pnpm test:ci                           # CI mode (coverage + optimized for CI)
+
+# View HTML report
+start coverage\index.html              # Windows
+open coverage/index.html               # Mac/Linux
+```
+
+**Report Formats**: HTML (`coverage/index.html`), LCOV (`lcov.info`), Cobertura (`cobertura-coverage.xml`)
+
+---
+
+## Troubleshooting
+
+### Quick Fixes
+
+| Issue | Solution |
+|-------|----------|
+| Test loading failed | `pnpm install && pnpm build`, restart VS Code |
+| Cannot find module | `pnpm build` from repository root |
+| Tests not discovered | Check `.vscode/settings.json`, reload window |
+
+### Complete Reset
+
+```powershell
+# From repository root
+pnpm install
+pnpm build
+pnpm test -- --clearCache
+
+# Restart VS Code: Ctrl+Shift+P → "Developer: Reload Window"
+```
+
+### VS Code Configuration
+
+Create `.vscode/settings.json` if Test Explorer doesn't work:
+
+```json
+{
+  "jest.rootPath": "tests",
+  "jest.jestCommandLine": "pnpm test",
+  "jest.autoRun": "off"
+}
+```

+# Test Plan for Agent365-nodejs SDK
+
+> **Note:** This plan is under active development. Keep updating as testing progresses.
+
+**Version:** 1.0  
+**Date:** December 4, 2025  
+**Status:** Draft
+
+---
+
+## Overview
+
+### Current State
+- ✅ Unit tests complete for `runtime` module
+- ✅ Unit tests complete for `observability` modules
+- ❌ Missing tests for `tooling` and `notifications` modules
+- ✅ Coverage reporting includes all 9 packages
+- ❌ No integration tests or CI/CD automation
+
+### Goals
+- Achieve **80%+ code coverage** across all modules
+- Implement unit tests for tooling and notifications modules
+- Implement integration tests for cross-module functionality
+- Integrate testing into CI/CD pipeline with coverage enforcement
+
+---
+
+## Testing Strategy
+
+**Framework:** `Jest` with `ts-jest`  
+**Coverage:** `Jest Coverage`  
+**Mocking:** `jest.mock`  
+**Async:** Native async/await
+
+**Test Pattern:** AAA (Arrange → Act → Assert)  
+**Test File Naming:** `<filename>.test.ts` (e.g., `power-platform-api-discovery.test.ts`)
+**Test Naming Convention:** `'should <expected_result> when <condition>'`  
+
