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
