test-driven-development

TDD unit tests define expected behavior before writing code. You write a failing test for a new feature, implement the minimum code required to pass it, and then refactor safely while keeping tests green.

Yes, this TDD workflow explicitly supports PHP testing using Pest or PHPUnit. It applies the Red-Green-Refactor cycle to PHP projects, ensuring clear test naming and fast feedback loops during feature development.

The Red-Green-Refactor cycle is a test-driven development process where you first write a failing test, implement the minimum code to make it pass, and then refactor the code while keeping tests green to reduce regression risk.

Yes, you can use Jest and Vitest for JavaScript and TypeScript unit testing workflows. The approach guides test organization and enforces fast feedback loops specifically within JS and TS environments.

Test-driven development helps with safe refactoring by defining behavior with tests before implementation. These tests act as a safety net, allowing you to modify and improve code structure without introducing regressions or breaking existing functionality.
