Write code using strict test-first workflows to ensure tests define and constrain behavior before implementation, reducing wasted effort.
Start by drafting a failing test for the target feature, then implement only enough code to pass that test.

Test-driven development (TDD) is a test-first workflow where you write a failing test, implement only enough code to pass it, and then refactor. This red-green-refactor cycle drives incremental design and constrains behavior before implementation.
To start test-first development for a new API, draft an initial failing test that defines the target behavior, then implement the minimum code required to pass that test. This provides contract-driven test scaffolding to validate your design.
Use test-driven development when starting new features, APIs, or modules from a spec. It is most useful for designing APIs through tests and validation, ensuring tests define behavior and drive design before you write implementation code.
Yes, test-first development works directly from a project specification by translating spec requirements into an initial failing test. This approach designs APIs through tests and validation, reducing wasted effort by constraining behavior upfront.
Writing a failing test before implementation ensures tests define and constrain behavior before code is written. This reduces wasted effort, drives incremental design across project contexts, and provides clear workflow guidance for new features.
