# Test Failure Analysis Report ## Summary - **Total Failing Tests**: 5 test suites with specific failures - **Test Status**: 9 failed, 2 passed, 11 total - **Root Causes Identified**: Configuration mismatches, missing files, TypeScript interface mismatches, and module resolution errors ## Detailed Analysis of Failing Tests ### 1. GitHub Release Workflow Test (`github-release.test.js`) **Status**: FAILING **Location**: `tests/github-release.test.js:28` **Root Cause**: - The release workflow uses `gh` CLI tool instead of GitHub Actions - Test expects `uses: actions/create-release` or `uses: softprops/action-gh-release` - Actual workflow uses: `gh release create` command **Test Expectation**: ```javascript expect(workflow).toMatch(/uses: actions\/create-release|uses: softprops\/action-gh-release/); ``` **Actual Implementation**: ```yaml - name: Create Release run: | gh release create ${{ github.ref_name }} \ --title "Release ${{ github.ref_name }}" \ --notes "$(cat CHANGELOG.md | head -50)" \ --verify-tag ``` **Fix Required**: Either update the test to accept `gh release create` or change workflow to use GitHub Actions. ### 2. Jest ESM Configuration Test (`jest-esm.test.js`) **Status**: FAILING **Location**: `tests/jest-esm.test.js:38` **Root Cause**: - Test expects `transform: {}` (empty transform) - Actual config has `transform` with ts-jest configurations **Test Expectation**: ```javascript expect(config).toContain('transform: {}'); ``` **Actual Implementation**: ```javascript transform: { '^.+\\.(ts|tsx)$': ['ts-jest', { useESM: true }], '^.+\\.js$': ['ts-jest', { useESM: true }] } ``` **Fix Required**: Update test to accept the ts-jest transform configuration for ESM. ### 3. Docker Build Tests (`docker-build.test.js`) **Status**: 3 FAILURES #### 3a. Missing .dockerignore file **Location**: `tests/docker-build.test.js:46` - **Root Cause**: `.dockerignore` file does not exist - **Fix Required**: Create `.dockerignore` file #### 3b. Missing ENV NODE_ENV **Location**: `tests/docker-build.test.js:92` - **Root Cause**: Dockerfile doesn't set `ENV NODE_ENV` - **Fix Required**: Add `ENV NODE_ENV=production` to Dockerfile #### 3c. HEALTHCHECK format mismatch **Location**: `tests/docker-build.test.js:201` - **Root Cause**: Test regex expects different format - **Current**: `HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \\` - **Test Expects**: Pattern `/HEALTHCHECK\s+--interval=.*CMD/` - **Fix Required**: Update test regex to match multiline HEALTHCHECK ### 4. Unit Tests - Module Resolution Failures **Status**: FAILING TO RUN **Files**: - `tests/unit/youtube-transcript.service.test.ts` - `tests/unit/mcp-server.test.js` - `tests/unit/youtube-transcript.service.test.js` **Root Cause**: Tests try to mock non-existent module paths - Attempting to mock `'../../src/utils/logger'` - Attempting to mock `'../../src/utils/cache'` - Attempting to mock `'../../src/services/youtube-transcript.service'` **Actual File Structure**: - Logger exists at: `src/utils/logger.ts` - Cache exists at: `src/utils/cache.ts` - Service exists at: `src/services/youtube-transcript.service.ts` **Fix Required**: The tests are compiled JavaScript files trying to import TypeScript source files. Need to update import paths or mock strategy. ### 5. Integration Test - TypeScript Interface Mismatch **Status**: FAILING TO COMPILE **File**: `tests/integration/end-to-end.test.ts` **Locations**: Lines 30, 59, 83, 126, 153, 184, 208 **Root Cause**: Mock data missing required `offset` property - YouTube Transcript API `TranscriptResponse` interface requires: ```typescript interface TranscriptResponse { text: string; duration: number; offset: number; // REQUIRED lang?: string; } ``` - Test mocks only provide: ```javascript { text: 'string', start: number, duration: number } ``` **Fix Required**: Update all mock transcript objects to include `offset` property. ## Fix Priority Order 1. **HIGH**: Fix TypeScript interface mismatch in integration tests (blocking compilation) 2. **HIGH**: Fix module resolution in unit tests (blocking test execution) 3. **MEDIUM**: Create .dockerignore file 4. **MEDIUM**: Update Dockerfile with ENV NODE_ENV 5. **LOW**: Update test expectations for GitHub Release workflow 6. **LOW**: Update Jest ESM test expectations 7. **LOW**: Fix HEALTHCHECK regex pattern ## Categorization by Fix Type ### Configuration Fixes - Create `.dockerignore` - Add `ENV NODE_ENV` to Dockerfile ### Test Expectation Updates - GitHub Release workflow test (accept gh CLI) - Jest ESM config test (accept ts-jest transform) - Docker HEALTHCHECK test (fix regex) ### Code Fixes - Add `offset` property to all mock transcript objects - Fix module import paths in unit tests ### Module Resolution Strategy - Tests are compiled to JavaScript but trying to import TypeScript files - Either: - Import from compiled `/dist` directory - Use path mapping in Jest config - Mock at a different level
