Key Features

• Test Isolation: Each test runs in a clean environment with:

  • Isolated environment variables
  • Clean logging handlers
  • Temporary directories for file operations

• Async Testing: Full support for async/await with pytest-asyncio

• Mocking: HTTP requests mocked using pytest-mock to avoid real API calls

• Fixtures: Reusable test data in conftest.py:

  • temp_dir: Temporary directory with automatic cleanup
  • mock_env_file: Sample .env file
  • mock_config_json: Sample config.json
  • sample_conversation_history: Test chat history
  • mock_perplexity_response: Sample API response

Test Statistics

• Total Tests: 116
• Passing: 116 (100%)
• Code Coverage: 97%
• Test Execution Time: ~1.2 seconds

Coverage Gaps

The 3% uncovered code consists of:

• Error handling edge cases in memory.py (lines 92-94, 111-112, 143-144)
• Rarely-used utility functions in utils.py (lines 101, 165)

These are defensive code paths that are difficult to trigger in tests.
