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
