TDD Agent Workflow

Red-green-refactor loop driven by an AI agent to build features test-first

Open Sourcefree

About

The TDD Agent workflow automates the red-green-refactor cycle. Given a feature description, the agent first writes a failing test suite (red), then iteratively writes the minimum implementation required to make each test pass (green), and finally refactors the code for clarity and performance while keeping tests green. The agent runs the test runner after every change and self-corrects on failures, producing production-ready, fully-tested code.

Details

Patterniterative
StepsAgent reads feature specification → Agent writes failing tests (red phase) → Agent runs test suite and confirms failures → Agent writes minimum implementation to pass tests (green phase) → Agent runs test suite and confirms all pass → Agent refactors implementation for quality → Agent runs final test suite to verify no regressions
Use CasesFeature development with correctness guarantees, Bug fixing with regression prevention, API endpoint implementation with contract tests
