test-driven-development

Test-first development enforces a strict RED-GREEN-REFACTOR cycle, requiring you to write failing unit tests before implementing minimal production code. This workflow prevents bugs by establishing correct behavior upfront and guiding incremental coding to pass tests.

The RED-GREEN-REFACTOR cycle is a test-first workflow where you first write a failing test (RED), implement minimal code to pass it (GREEN), and then refactor the codebase. It reduces regressions across diverse codebases during feature development and bug fixes.

You use unit tests to guide development by writing a failing test to establish desired behavior, running the test suite to observe the failure, implementing minimal code to pass, and refactoring. This test-first approach ensures resilient software for new features and refactors.

Yes, test-driven development is applicable to feature development, bug fixes, and refactoring across diverse software projects. It prevents fragile code by enforcing a test-first workflow that reduces regressions and ensures reliable behavior from the start.

Writing failing tests before production code leads to reliable features by establishing correct behavior upfront. The RED-GREEN-REFACTOR workflow enforces minimal, incremental coding to pass tests, which prevents production bugs and reduces regressions.

No specific framework is required, as the test-first workflow runs tests with a standard testing framework of your choice. The process focuses on the RED-GREEN-REFACTOR cycle, requiring only a standard framework to run unit tests and observe failures before implementation.
