Can I use this for API testing?

Absolutely. It provides specialized patterns for FastAPI using TestClient and general integration strategies for RESTful services.

Which Python testing frameworks are supported?

The skill primarily focuses on pytest as the industry standard, but it can detect and manage unittest, tox, and nox configurations, often providing migration paths to pytest.

What is the recommended test distribution?

The skill follows a healthy testing pyramid: approximately 75% unit tests, 20% integration tests, and 5% end-to-end tests for optimal speed and reliability.

Does this skill support asynchronous testing?

Yes, it includes specific patterns and decorators for both pytest-asyncio and pytest-anyio to handle async functions and mock async dependencies effectively.

How does it help with test isolation?

It implements advanced mocking and patching techniques to isolate external dependencies, ensuring that unit tests remain fast and deterministic.

セキュリティとテスト

Implements comprehensive Python testing strategies using pytest, including unit tests, integration tests, and advanced mocking patterns.

The Python Testing Specialist skill transforms Claude into a domain-expert testing assistant for Python environments. It provides standardized patterns for the Arrange-Act-Assert methodology, sophisticated mocking techniques using AsyncMock and patch, and specialized support for asynchronous testing. By detecting existing project configurations like pyproject.toml or conftest.py, the skill tailors its advice to your specific stack—whether you are writing unit tests for business logic, integration tests for databases, or end-to-end workflows for FastAPI applications. It ensures high code quality by enforcing coverage best practices and providing reusable fixture patterns.
