tdd-workflow

You can automate the RED-GREEN-REFACTOR cycle by enforcing a workflow that starts with a failing test, implements the minimal code to pass it, and validates changes through green tests before refactoring. This prevents regressions and drives design.

The best way to start writing failing tests first is to reproduce the desired behavior in a test, run it to observe the failure, implement the minimal code to make it pass, and then run all tests again to validate.

Yes, test-driven development works with any codebase that has automated tests and project-appropriate tooling. It applies the RED-GREEN-REFACTOR loop to guide both bug fixes and feature development while maintaining test coverage.

You maintain test coverage during incremental code refactoring by ensuring all tests remain green after implementing the minimal passing fixes. The automated TDD workflow validates changes continuously to prevent regressions during improvements.

You should use TDD for preventing regressions because it disciplines developers to write failing tests first and implement minimal passing fixes. This ensures tests drive design and validate changes continuously throughout the development cycle.
