Pull Request Overview
This PR adds a comprehensive testing framework to the ConnectKit application with 7 specialized testing workflows covering performance, end-to-end, contract, chaos engineering, API, smoke, and mutation testing. Each workflow implements industry best practices with proper error handling, artifact management, and detailed reporting to ensure enterprise-grade quality assurance across the entire application stack.
- Performance Testing: K6 and Artillery-based load, stress, and spike testing with configurable thresholds
- End-to-End Testing: Multi-browser Playwright tests including mobile and visual regression testing
- Contract Testing: Pact-based consumer-driven contract testing between frontend and backend services

The condition checks for exact string equality with '0', but jq may return numeric 0 or null. This could cause the calculation to fail. Use proper numeric comparison: [ \"$BACKEND_SCORE\" != \"0\" ] && [ \"$BACKEND_SCORE\" != \"null\" ]

[nitpick] The hardcoded import path '../../src/app' may not exist in all project structures. Consider making this configurable or checking if the file exists before importing.

- Fixed api-testing.yml to use 'db' instead of 'postgres' service name - Fixed smoke-testing.yml to use correct container names (connectkit-db, connectkit-redis) - Added continue-on-error to contract testing artifact download
- Fixed E2E Testing workflow: - Removed problematic job dependencies between setup and test jobs - Each test job now uses service containers for PostgreSQL and Redis - Services are self-contained within each job for proper availability - Added proper health checks and wait conditions - Fixed API Testing workflow: - Consolidated jobs to ensure service availability - Added service containers to each test job - Fixed Newman and REST Assured test execution - Ensured proper backend startup before tests - Updated Playwright configuration to properly locate test files These changes ensure all test jobs have access to required services and run independently.
- Removed npm cache configuration from workflows - Package-lock.json files don't exist yet in the repository - This was causing Node.js setup step to fail
- Added --include=dev flag to npm ci for backend installation - tsx is needed to run TypeScript files in development mode - This ensures the backend can start properly for tests
…ments - Backend requires JWT secrets to be at least 32 characters long - Updated test JWT secrets to meet minimum length requirement - This fixes the backend startup failure in test environments
- Backend requires ENCRYPTION_KEY to be 64 hex characters (32 bytes) - Updated test encryption key to valid hex format - This fixes the backend startup encryption validation error
- Changed health check URL from /api/health to /health - Backend health endpoint is at root /health not under /api - This fixes the 404 errors during health checks
- Added empty REDIS_PASSWORD env var to E2E testing workflow - This matches the API testing configuration that works successfully - Ensures Redis connection doesn't fail due to missing password config
- Changed from 'npm run dev' to 'npx tsx watch src/index.ts' - This ensures tsx is found in node_modules even if not in PATH - Matches the direct execution pattern that works in API tests
- Install dependencies from root using npm ci to properly resolve workspace packages - Use npm run dev:backend and dev:frontend commands that leverage workspace scripts - Remove individual cd backend/frontend and npm ci commands that break in monorepo setup - Ensures 'cors' and other backend dependencies are properly available The issue was that the workflow was trying to install dependencies separately in each workspace directory, but in an npm workspaces monorepo, dependencies must be installed from the root to properly link workspace packages.
- Install all dependencies from root with npm ci - Use Stryker v7.3.0 which is compatible with vitest 1.x - Fixed version conflicts between Stryker and vitest - Removed npm cache configuration that doesn't work with monorepo - Install Stryker dependencies at root level for proper resolution This ensures mutation testing can run properly in the monorepo structure.
- Removed conditional if statements for Firefox, WebKit, and Mobile tests - All browser tests now run automatically on every PR - This ensures comprehensive cross-browser compatibility testing - Tests will run in parallel for: Chromium, Firefox, WebKit (Safari), and Mobile devices This provides better test coverage across all major browsers and mobile devices.
- Create CI-specific Playwright config without webServer to prevent port conflicts - Assign unique ports to each browser test job: - Chromium: 3000/3001 - Firefox: 3100/3101 - WebKit: 3200/3201 - Mobile: 3300/3301 - Visual: 3400/3401 - Update all test commands to use CI config and dynamic port variables - Remove unnecessary mobile test configuration
- Use npx vite --port for frontend to respect dynamic port assignment - Use cd backend && npm run dev for backend with PORT env variable - Ensures each browser test gets its assigned unique port
…est creation - Created comprehensive keyboard navigation test suite with 12 test scenarios - Added keyboard test helper utilities for reusable test functions - Fixed workflow to use existing test files instead of creating inline versions - Updated Axe-core test configuration to prevent overwriting existing tests - Enhanced test reporting with better error handling and artifacts - Tests now properly validate WCAG 2.1 Level AA keyboard accessibility

The correct way to address this unused import is to remove Page from the import statement on line 1 in frontend/tests/accessibility/keyboard.spec.ts, while retaining test and expect (both are clearly in use). No other code changes, import injections, or refactoring are required. All changes should be limited to the first line of the file, removing Page from the destructured import list.

To fix the problem, update the check for unsafe schemes on line 178, expanding the predicate to also block href values that start with data: or vbscript:, in addition to javascript:. This should be a case-insensitive check, and can be done by normalizing href to lower case and trimming whitespace, as shown in best practices. Since the check is only made in one place (within the test for link activation), limit the edit to the predicate in the corresponding if-statement, ensuring existing functionality remains unchanged.
Edit:
- Update line 178 in
frontend/tests/accessibility/keyboard.spec.tsto include checks fordata:andvbscript:schemes. - Optionally, trim and lowercase the
hreffor robustness.
No additional imports are required.

To fix this issue, simply remove the assignment to cycleDetected on line 356, as it is not used anywhere after being set. This will clean up the code by removing dead code and improve its maintainability. Specifically, delete the assignment statement cycleDetected = true; within frontend/tests/accessibility/keyboard.spec.ts in the test block should not trap keyboard focus unintentionally. No further changes or imports are required.
