Testing Philosophy

About

The Testing Philosophy skill provides Claude with a rigorous framework for designing and evaluating test suites across any programming language. It guides the AI to prioritize behavioral contracts, minimize brittle mocking, and follow the Arrange-Act-Assert (AAA) pattern. By focusing on confidence-driven coverage rather than arbitrary percentages, this skill ensures that tests serve as a reliable safety net for refactoring and documentation, effectively reducing technical debt and preventing regressions in complex codebases.

Key Features

• Behavior-driven testing strategies that survive internal refactoring
• Standardized AAA (Arrange, Act, Assert) test structure guidance
• Heuristics for identifying and fixing common test smells like over-mocking
• 2 GitHub stars
• Strict mocking guidelines focused on system boundaries and external APIs
• Canon TDD workflow integration for AI-assisted development

Use Cases

• Architecting a new test suite for core business logic or complex algorithms
• Refactoring brittle test suites that break during internal code changes
• Reviewing existing test quality to improve coverage for critical edge cases
