Test-first development discipline is enforced by requiring a newly failing test before any production implementation, ensuring you validate behavior before writing code. This prevents drifting into code-first habits and reduces bugs.

The Red-Green-Refactor loop is an iterative unit testing cycle that starts with a failing test, implements minimal code to pass it, and then refactors while keeping tests green. This enforces strict test-first execution and repeatable verification.

To stop writing production code first, apply strict stop rules that halt the workflow if tests pass on the initial run or if implementation is written before tests. This enforces test-first discipline and prevents feature drift.

Unit tests passing on the first run usually means the test is not validating newly written behavior. A test-first workflow stops execution if this happens, ensuring every Red-Green-Refactor cycle starts with a genuinely failing test.

No, bundling multiple features violates test-first discipline. Each iteration must decompose features into small steps with repeatable verification, stopping the workflow if multiple features are bundled into one cycle to maintain strict validation.

TDD iterations are kept auditable by using a clear output structure that provides a required reporting format for the RED, GREEN, and REFACTOR phases. This enforces consistent cycle-based test execution tracking across the development workflow.
