TDD Workflow
Implements Test-Driven Development workflow for feature implementation.
Quick Start
Run TDD Cycle
from scripts.tdd_workflow import TDDWorkflow
workflow = TDDWorkflow(project_dir)
result = await workflow.implement_feature(
feature_id="auth-001",
acceptance_criteria=criteria
)
if result.passed:
print("Feature implemented and verified!")Individual Phases
# Red: Write failing test
test_path = await workflow.write_test(feature_id)
# Green: Implement to pass
await workflow.implement_code(feature_id)
# Refactor: Clean up
await workflow.refactor(feature_id)TDD Cycle

└─────────────────────────────────────────────────────────────┘TDD Principles
| Principle | Description |
|---|---|
| Tests First | Always write tests before implementation |
| Minimal Code | Write only enough code to pass tests |
| Small Steps | Make incremental changes |
| Fast Feedback | Run tests frequently |
| Refactor Often | Keep code clean |
Test Types
| Type | Purpose | When to Write |
|---|---|---|
| Unit | Test individual functions | RED phase |
| Integration | Test component interaction | After GREEN |
| E2E | Test full feature flow | VERIFY phase |
Integration Points
- coding-agent: Executes TDD workflow
- browser-e2e-tester: Runs E2E tests
- error-recoverer: Handle test failures
- progress-tracker: Track test metrics
