FAQPage Schema
What is test-driven development and how does it validate software behavior?▼

Test-driven development is a test-first workflow where you write a failing test, implement minimal code to pass it, and refactor while keeping tests green to ensure correct software behavior.

How do I start writing tests before production code for a new feature?▼

To write tests before production code, start by writing a failing test that validates the expected behavior, verify it fails, then implement the minimal code needed to make it pass.

Can I use the red-green-refactor workflow for bug fixes and refactoring?▼

Yes, the red-green-refactor workflow applies to bug fixes and refactoring by validating behavior changes before implementation, providing guardrails to ensure software correctness.

What's the best way to ensure correct software behavior during feature development?▼

The best way to ensure correct software behavior during feature development is adopting a test-first workflow that enforces writing failing tests before implementing the minimal code to pass them.

Do I need any specific testing frameworks to adopt a test-first workflow?▼

No specific testing frameworks are required to adopt a test-first workflow. The approach is applicable across feature development and bug fixes to validate changes before implementation.
