Does this skill support specific languages like Java or Python?

This skill provides universal principles applicable to all stacks. For language-specific syntax and conventions, use testing-strategy-java, testing-strategy-node, or testing-strategy-python.

Why should I test behavior instead of implementation?

Testing behavior ensures your tests stay green during refactoring as long as the output remains the same. Testing implementation details makes tests fragile and prone to breaking even when the feature still works.

How does this skill handle non-deterministic tests?

It provides guidance on eliminating randomness, mocking system clocks, and removing dependencies on execution order to ensure tests pass or fail consistently.

What is the AAA pattern in testing?

AAA stands for Arrange, Act, and Assert. It is a pattern that organizes tests into three distinct sections: setting up the data, executing the action, and verifying the result.

安全与测试

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.
