tdd-workflow

Test-driven development workflow enforcing 80%+ coverage across unit, integration, and E2E tests. This skill ensures all code development follows TDD principles with comprehensive test coverage. ALWAYS write tests first, then implement code to make tests pass. For each user journey, create comprehensive test cases: This step is mandatory and is the RED gate for all production changes. Before modifying business logic or other production code, you must verify a valid RED state via one of these paths: A test that was only written but not compiled and executed does not count as RED. Do not edit production code until this RED state is confirmed. If the repository is under Git, create a checkpoint commit immediately after this stage is validated. Recommended commit message format: Write minimal code to make tests pass: If the repository is under Git, stage the minimal fix now but defer the checkpoint commit until GREEN is validated in Step 5.
