The test-driven development (TDD) cycle follows a RED-GREEN-REFACTOR sequence: you write a failing test first, implement the minimal code to pass it, then refactor the code for quality. This enforces test-first principles to drive behavior specification.

Use test-driven development when building new features, isolated modules, or greenfield projects where behavior specification drives implementation. It is ideal for defining API contracts in new microservices to ensure all endpoints are covered by tests before deployment.

To start test-first development, initiate the TDD cycle by writing a failing test for the desired feature behavior. Then create the minimal implementation to make the test pass, and finally refactor the code while keeping the tests green.

Yes, test-driven development is highly applicable for greenfield projects and new microservices. It helps define API contracts upfront and builds a robust test suite from the ground up, ensuring all new endpoints are fully covered by tests before deployment.

Test-driven development integrates with quality assurance frameworks to enforce test-first principles throughout the software engineering process. This ensures new code is built with a robust test suite from the ground up, maintaining high quality standards.

Test-driven development is best suited for new features, isolated modules, and greenfield projects. It focuses on behavior specification to drive implementation, so applying it to legacy code without clear specifications may be less effective.
