概要
The Testing & QA Strategy skill empowers Claude to design and execute comprehensive testing suites for Python applications. It goes beyond simple unit testing by integrating 'Extended Thinking' to identify hidden edge cases, formulate testable hypotheses, and optimize test strategies. Supporting frameworks like pytest and unittest, the skill provides sophisticated patterns for mocking, fixture management, and coverage analysis, making it indispensable for Test-Driven Development (TDD) and maintaining mission-critical codebases.
