About
This skill provides a comprehensive framework for implementing professional-grade testing in Python projects. It guides developers through the entire testing lifecycle, from basic unit tests using the AAA (Arrange, Act, Assert) pattern to advanced concepts like fixture management, asynchronous testing, and external dependency mocking. Whether you are building a new test suite from scratch or improving coverage for complex APIs and databases, this skill ensures your code remains reliable, maintainable, and bug-free through standardized best practices and modern pytest conventions.
