test-driven-development

Test-driven development is enforced by mandating the creation of failing tests before writing any production code. This ensures code quality and prevents regressions by verifying behavior and catching errors early in the development cycle.

The Red-Green-Refactor cycle is a TDD workflow where you write a failing test first, then implement minimal code to make it pass, and finally refactor. This loop guides developers to ensure quality and prevent bugs.

Yes, this TDD approach applies to all software development tasks including new features, bug fixes, and refactoring. It requires strict adherence to writing tests first to verify behavior and catch errors before implementation.

To start implementing a feature with a test-first workflow, write a failing test that defines the desired behavior. Observe the test fail, then write the minimal production code required to make it pass before refactoring.

Writing failing tests before production code guarantees that your tests actually verify behavior and catch errors early. This strict test-first approach prevents bugs, improves overall code quality, and stops regressions.

Test-driven development integrates into agile software development by enforcing a rigorous test-first workflow. It ensures all new code is written with comprehensive tests that fail before implementation, thereby preventing bugs and improving quality.
