Package installation - Argument forwarding - Error handling - Cleanup 2. **Testing Framework Modules** - Protocol validation (`packages/testing/tests/unit/protocol/index.test.ts`) - Wrapper utilities (`packages/testing/tests/unit/wrappers/index.test.ts`) - Language support (`packages/testing/tests/unit/languages/index.test.ts`) - Performance testing (`packages/testing/tests/unit/performance/index.test.ts`) - Test generation (`packages/testing/tests/unit/generation/index.test.ts`) ## 📋 Testing Best Practices ### Test Structure ```typescript describe('Component/Function Name', () => { // Setup and teardown beforeEach(() => { // Reset mocks, setup test environment }); describe('Happy Path', () => { it('should handle normal operation correctly', () => { // Test expected behavior }); }); describe('Error Handling', () => { it('should handle specific error gracefully', () => { // Test error scenarios }); }); describe('Edge Cases', () => { it('should handle boundary conditions', () => { // Test edge cases }); }); }); ``` ### Testing Strategy 1. **Unit Tests**: Mock external dependencies, test pure logic 2. **Integration Tests**: Test component interactions with real dependencies 3. **E2E Tests**: Test complete workflows from CLI to output ### Mock Strategy - Use Vitest's built-in mocking capabilities - Mock file system operations for speed - Mock network requests - Mock child processes - Use real implementations for critical paths in integration tests ## 🎯 Success Metrics ### Quantitative Goals - **Test Files**: 19 → 45-50 files (2.5x increase) - **Code Coverage**: Target 80%+ for critical paths - **Command Coverage**: 100% of user-facing commands tested - **Tool Coverage**: 100% of MCP tools tested ### Qualitative Goals - All error paths have tests - Mock external dependencies properly - Fast test execution (< 30s for full suite) - Clear test descriptions - Examples serve as documentation ## 🚀 Getting Started 1. **Check out feature branch**: `feat/double-test-coverage` 2. **Run existing tests**: `npm test` 3. **Check current coverage**: `npm run test:coverage` 4. **Start with Phase 1A** (Foundation tests) 5. **Commit frequently** with descriptive messages 6. **Create PR** when phase is complete ## 📈 Progress Tracking -
