Test-Driven Development helps you prevent regressions and reduce guesswork by forcing you to define desired behavior with a failing test before writing production code.
Tell the tdd skill what feature or function signature you want to build, and ask it to guide you through writing one failing test, implementing the minimum passing code, and refactoring while running the full test suite each time.

Test-driven development prevents regressions by requiring you to write a failing test defining the desired behavior before writing any production code. You then implement the minimum code to pass the test and refactor without changing behavior.
The red green refactor cycle is a test-driven development loop where you write a failing test first, implement the minimum code to make it pass, and then refactor the code while ensuring all tests still pass.
To start writing unit tests for a new function, provide the function signature to the test-driven development guide and ask it to help you write one failing test for the smallest next behavior before implementing the passing code.
You should write failing tests before production code when implementing unit-level features, edge cases, or integration-ready development to reduce guesswork and enforce clear sequencing of behavior-driven design.
To decide what to test next during software design, progress from degenerate and happy paths to variations, edge cases, error cases, and finally integration. This behavior-driven approach ensures comprehensive coverage.
Test-driven development works for refactoring by requiring you to run all tests after each change to verify the behavior remains unchanged. This ensures the refactoring process does not introduce regressions into the software.
