Can it help me mock external database connections?

Absolutely. It includes patterns for using unittest.mock and monkeypatch to isolate your code from external databases and third-party APIs.

What is the recommended test structure provided by this skill?

The skill promotes the Arrange-Act-Assert (AAA) pattern to ensure that every test is clearly structured, readable, and focused on a single responsibility.

Does this skill support the pytest framework?

Yes, this skill is specifically optimized for pytest, providing patterns for fixtures, parameterization, and pytest-specific configurations.

Does it support testing for modern async Python code?

Yes, it provides specialized patterns for testing asynchronous functions and concurrent operations using pytest-asyncio.
