Provides language-agnostic testing principles to ensure robust, maintainable, and high-quality codebases.
The Universal Testing Strategy skill equips Claude with fundamental engineering principles for software verification that apply across any technology stack. It enforces best practices such as the AAA (Arrange, Act, Assert) pattern, behavior-driven testing over implementation details, and the Test Pyramid architecture. By focusing on determinism, isolated test data, and comprehensive edge case coverage, this skill helps developers build test suites that are resilient to refactoring and highly reliable.
