Test-driven development begins by running the RED phase to write a failing test, then implementing just enough code to pass, and refactoring for clarity. This structured RED-GREEN-REFACTOR workflow ensures incremental, verifiable progress.

The AAA testing pattern organizes tests into clear setup, action, and assertion phases. It provides structure to test-driven development by ensuring each test logically separates the arrange, act, and assert steps.

The RED-GREEN-REFACTOR cycle enforces verifiable delivery by requiring a failing test first, writing minimal implementation code to pass it, and then refactoring for quality. This prevents skipped tests and over-engineering.

Common test-driven development anti-patterns include over-engineering solutions and skipping tests entirely. Structured workflows provide anti-pattern guidance to avoid these pitfalls and maintain clear development progress.

Yes, a structured test-driven development workflow is applicable to iterative agile delivery. It guides software engineering teams from failing tests to working code, ensuring consistent quality assurance throughout feature development.

Test-driven development lacks consistent quality when teams fail to enforce a repeatable workflow. Adopting a structured RED-GREEN-REFACTOR cycle with the AAA pattern guides engineers from failing tests to working code.
