TDD Automation Flow
The faster the feedback loop, the more effective your TDD process becomes.
Local Automation
Use file watchers to run your tests immediately upon saving a file.
Python (pytest-watch)
ptw .
JavaScript (Jest/Vitest)
npm test -- --watch
Essential Flow
- Save file -> Tests run automatically.
- If Fail: Write code to pass.
- If Pass: Refactor and repeat.
CI/CD Integration
TDD doesn't stop at the local machine. Use Git hooks and CI pipelines to enforce the testing discipline.
- Pre-commit hooks: Run linting and fast unit tests before allowing a commit.
- PR Gates: Prevent merging code that doesn't have 100% test pass rate.
- Coverage Reports: Monitor test coverage as a metric for team health (not a target!).
