Test-Driven Development (professional)

Skill text is English; answer in the user’s preferred language when rules or the conversation specify it.

Use references such as Kent Beck's TDD and Growing Object-Oriented Software for methodology; this skill encodes RED-GREEN-REFACTOR discipline, test design principles, refactoring safety, and test quality standards — not generic "write more tests" advice.

Boundary

test-driven-development-pro owns RED-GREEN-REFACTOR cycle execution, test-first discipline, refactoring safety, and test design principles. testing-pro owns test strategy, pyramid design, and CI integration. bug-discovery-pro owns defect discovery patterns. Domain *-pro skills own testing patterns specific to their stack (e.g., react-pro for component testing).
