Test-driven development prevents regressions by enforcing the RED-GREEN-REFACTOR cycle: writing a failing test first, writing minimal code to pass, and then refactoring. This ensures new code never breaks existing functionality.

The RED-GREEN-REFACTOR cycle is a testing protocol where you write a failing test, implement minimal production code to make it pass, and then refactor the code. This methodology ensures robust software design and catches bugs early.

To write tests before implementation, start by defining feature requirements as failing tests, then write the minimal code required to pass those tests, and finally refactor for code quality. This strict testing protocol applies to all new feature development.

Yes, test-driven development is fully applicable to bug fixes and refactoring tasks. You write a failing test that reproduces the bug or verifies the refactored behavior before modifying any production code to ensure code quality.

Test-driven development improves code design by enforcing strict testing protocols that require you to write testable, modular code. This commitment to writing failing tests first naturally encourages highly decoupled and robust software architectures.

Strict testing protocols require a commitment to writing failing tests before any production code. You should anticipate this overhead for new features, bug fixes, and refactoring tasks where achieving immediate testable and modular code design is critical.
