Which test runner does this skill focus on?

It primarily focuses on pytest, the industry standard for Python, covering its advanced features like fixtures, markers, and parameterization.

Can I use this for integration testing?

Absolutely. The skill covers mocking external services and setting up complex, multi-scoped fixtures suitable for integration and end-to-end tests.

Is it suitable for beginners to TDD?

Yes, it provides clear examples of the Arrange-Act-Assert pattern and exception testing, making it an excellent resource for learning Test-Driven Development.

How does it handle external dependencies?

It provides detailed patterns for using the unittest.mock library and pytest's monkeypatch fixture to isolate your code from databases, APIs, and environment variables.

Does this skill support asynchronous Python code?

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