Mutation testing evaluates test quality by introducing small, deliberate bugs (mutations) into code and checking if tests catch them. This provides a behavioral measure of test effectiveness beyond simple coverage metrics.

Why mutation testing matters: Tests can achieve 100% line coverage while missing critical bugs. Mutation testing reveals if tests actually verify behavior or just execute code.

This skill uses Go's go/ast and go/parser packages to generate intelligent mutations by analyzing code structure.

通過突變測試驗證測試套件的質量。生成智能代碼突變，運行測試以驗證它們捕獲更改，並識別測試覆蓋範圍中的差距。在評估測試有效性、驗證新編寫的測試或提高關鍵任務代碼的測試質量時使用。 來源：roasbeef/claude-files。
