Test-Driven Development (TDD) uses the Red-Green-Refactor cycle, where you write a failing test (Red), write production code to pass it (Green), and then refactor the code while tests remain green. This ensures robust software.

To start writing tests before production code, write a failing test defining the desired behavior, implement the minimum code to pass it, and refactor safely. This TDD approach applies to both pure functions and API endpoints.

Use Test-Driven Development when developing complex business logic, building algorithms, or aiming for high code quality. TDD is ideal for ensuring robust outcomes for both pure functions like password validation and API endpoints.

Common Test-Driven Development pitfalls include skipping the refactoring step or writing tests that are too broad. Focus on writing failing tests before production code and refactor only when tests pass to avoid these issues.
