Test-driven development begins by writing tests before implementation code. Write minimal tests for the smallest feature unit, implement code to pass those tests, run verification, review changes, and commit incrementally. This cycle reduces bugs and enables safe refactoring across monorepos or subprojects.

Divide work into planable units by identifying the smallest independent change, writing tests for it, implementing minimally to pass tests, and committing incrementally. This approach ensures each piece is reviewable, testable, and reduces coordination overhead in team environments.

Refactoring with test-driven discipline requires writing tests first as a safety net, implementing changes incrementally, running tests and linters after each change, and committing only when builds pass. This enforces guideline-driven practices and catches issues early.

Yes. Test-driven development applies directly to monorepo and subproject contexts by enabling incremental commits, structured code reviews, and independent verification of each feature unit, reducing coordination challenges and verification overhead.

Structured code review discipline paired with incremental commits allows reviewers to assess smaller, focused changes with clearer intent. Combining TDD practices with this discipline reduces rework, catches issues earlier, and improves team alignment on implementation choices.
