tdd-workflow

Test-driven development using the red-green-refactor workflow starts by defining the smallest observable behavior, writing a focused failing test to verify red, implementing minimal production code to reach green, and then performing a safe refactor.

The best way to fix regressions with a test-first approach is to reproduce the bug, add a regression test that captures the failure, apply a small safe production change to fix the issue, and re-run validation loops to confirm the fix.

A TDD workflow needs a build-mode checklist to maintain development discipline and guide builds through rigorous test planning, focused validation, and explicit rollout validations across the structured core loop.

Yes, you can use this TDD workflow to validate new features before production code changes by writing focused tests that define observable behaviors, running minimal validation loops, and ensuring all tests pass before integration.

You should not use a red-green-refactor loop when building features or fixing regressions that lack observable behaviors to test, as the workflow requires defining explicit test cases and running focused validation loops before changing production code.
