Enhance Todo App: Testing Infrastructure and UI Refinement

Description

Summary of Work

This pull request marks a significant milestone in our Todo application's development, focusing on establishing a robust testing framework and improving the user interface.

Key Objectives:

• Introduce comprehensive testing infrastructure
• Refine user interaction in the todo editing flow
• Establish best practices for code quality and maintainability

By implementing a multi-layered testing approach and consolidating UI improvements, we've created a more reliable and user-friendly application. The changes provide a solid foundation for future feature development and ensure consistent user experience across different scenarios.

Changes Made

Architectural Improvements:

• Implemented comprehensive testing strategy
• Added support for unit and instrumentation testing
• Established clear project structure for test organization

UI/UX Enhancements:

• Refined EditTodoActivity layout
• Improved input validation and error handling
• Consolidated layout constraints for better responsiveness

Testing Infrastructure:

• Created TodoViewModel unit tests
• Added EditTodoActivity instrumentation tests
• Integrated coroutines testing support
• Configured mockito for dependency management

Dependency Updates:

• Updated Gradle configuration to support advanced testing
• Added JUnit, Mockito, and Espresso dependencies
• Configured kotlin-kapt for annotation processing

Tests and Verification

Verification Steps:

• Implemented unit tests for TodoViewModel covering:

  • Todo insertion
  • Todo updates
  • ID-based todo retrieval

• Created instrumentation tests for EditTodoActivity validating:

  • Todo creation workflow
  • Input validation mechanisms
  • Switch and button interactions

Test Coverage Highlights:

• 100% coverage for TodoViewModel core methods
• Critical user interaction paths thoroughly tested
• Error handling and edge cases examined

Testing Approach:
