How does it handle database state between tests?

It utilizes pytest fixtures for the 'Arrange' and 'Teardown' phases, ensuring each test has a clean database state and doesn't leak data into other tests.

What testing framework does this skill use?

The skill focuses on pytest, the modern industry standard for Python, along with the built-in unittest.mock library for dependency isolation.

Does this skill support asynchronous Python code?

Yes, it includes specific patterns and best practices for testing async functions and concurrent operations using pytest-asyncio.

Can I use this for integration testing or only unit tests?

It covers the full spectrum of testing, including unit tests for isolated logic, integration tests for component interaction, and functional tests for end-to-end features.
