Enforces a disciplined, test-first approach to software tasks, ensuring no production code is written before a failing test is in place. It codifies the RED-GREEN-REFACTOR loop and pairs well with systematic debugging when stuck on a failing task.
Write a failing test first, run it to observe the failure, then implement the minimal production code to pass.

Test-driven development (TDD) is a test-first workflow where you write a failing test, implement minimal code to pass it, then refactor. The red-green-refactor cycle enforces this discipline for new features, bug fixes, and refactors across software projects.
To implement a feature with test-first development, write a failing test for the desired behavior first, run it to verify the failure, then write the minimal production code required to satisfy the test suite and pass the test.
Yes, test-driven development applies to bug fixes and refactoring existing code. You write a failing test that reproduces the bug or verifies the refactored behavior, then implement minimal production code to make the test suite pass.
A strict test-first approach may not suit exploratory prototyping or throwaway scripts where writing failing tests beforehand adds overhead without yielding long-term software engineering discipline or behavior verification.
Tests must fail first in TDD to prove they actually validate the target behavior and detect the missing implementation. Observing the failure ensures the test suite is meaningful before writing minimal production code to pass it.
