test-driven-development

To apply test-driven development for a new feature, write a failing unit test specifying the desired behavior first, implement minimal production code to pass it, then refactor to complete the red-green-refactor cycle.

The red-green-refactor cycle in test-driven development is a sequence where you write a failing test first, implement the minimal code to make it pass, and then clean up the design through refactoring with confidence.

Yes, you can use test-driven development for bug fixes and refactoring by writing a failing unit test that validates the desired behavior before changing production code, ensuring test coverage and software design clarity.

A test-first workflow prevents scope creep by validating behavior before implementation, requiring explicit tests for desired functionality, and enforcing minimal code production to pass the failing unit test without adding unnecessary features.

Test-driven development requires explicit tests before production code to prevent test-skipping patterns, enforce the test-first philosophy, and ensure that all implemented features have validating unit tests for regression protection.
