# Test-Driven Development Workflow This skill ensures all code development follows TDD principles with comprehensive test coverage. ## When to Activate - Writing new features or functionality - Fixing bugs or issues - Refactoring existing code - Adding API endpoints - Creating new components ## Core Principles ### 1. Tests BEFORE Code ALWAYS write tests first, then implement code to make tests pass. ### 2. Coverage Requirements - Minimum 80% coverage (unit + integration + E2E) - All edge cases covered - Error scenarios tested - Boundary conditions verified ### 3. Test Types #### Unit Tests - Individual functions and utilities - Component logic - Pure functions - Helpers and utilities #### Integration Tests - API endpoints - Database operations - Service interactions - External API calls #### E2E Tests (Playwright) - Critical user flows - Complete workflows - Browser automation - UI interactions ## TDD Workflow Steps ### Step 0: Detect the Test Runner Do not assume `npm test`. The commands in the steps and examples below use `<test>`, `<test-watch>`, and `<coverage>` as placeholders for the project's actual runner. Resolve them once before starting: 1. **Run the package-manager detector** (ships with ECC): ```bash node scripts/setup-package-manager.js --detect ```
