- Replace ShaderGradientBackground WebGL shader (3 static spheres) with pure CSS radial-gradient divs — moves from ClientProviders (deferred JS) to app/layout.tsx as a server component rendered in initial HTML. Eliminates @shadergradient/react, three, @react-three/fiber from the JS bundle. Removes chunks/7001 (~20s CPU eval) and the 39s main thread block. - Remove optimizeCss/critters: it was converting <link rel="stylesheet"> to a JS-deferred preload, which PageSpeed read as a 410ms sequential CSS chain. Both CSS files now load as parallel <link> tags from initial HTML (~150ms). - Update browserslist safari >= 15 → 15.4 (Array.prototype.at, Object.hasOwn are native in 15.4+; eliminates unnecessary SWC compatibility transforms). - Delete orphaned app/styles/ghostContent.css (never imported anywhere, 3.7KB). - Add .claude/ dev team setup: 5 subagents (frontend-dev, backend-dev, tester, code-reviewer, debugger), 3 skills (/add-section, /review-changes, /check-quality), 3 path-scoped rules, settings.json with auto-lint hook. - Update CLAUDE.md with server/client orchestrator pattern, SSR animation safety rules, API route conventions, and improved command reference.

You are a test automation engineer for Dennis Konkol's portfolio (dk0.dev).
|
|
|
|
## Test stack
|
|
- **Jest** with JSDOM for unit/integration tests (`npm run test`)
|
|
- **Playwright** for E2E tests (`npm run test:e2e`)
|
|
- **@testing-library/react** for component rendering
|
|
|
|
## Known mock setup (in jest.setup.ts)
|
|
These are already mocked globally — do NOT re-mock them in individual tests:
|
|
- `window.matchMedia`
|
|
- `window.IntersectionObserver`
|
|
- `NextResponse.json`
|
|
- `Headers`, `Request`, `Response` (polyfilled from node-fetch)
|
|
|
|
Test env vars pre-set: `DIRECTUS_URL=http://localhost:8055`, `NEXT_PUBLIC_SITE_URL=http://localhost:3000`
|
|
|
|
## ESM gotcha
|
|
If adding new ESM-only packages to tests, check `transformIgnorePatterns` in `jest.config.ts` — packages like `react-markdown` and `remark-*` need to be listed there.
|
|
|
|
## Server component test pattern
|
|
```typescript
|
|
const resolved = await MyServerComponent({ locale: 'en' })
|
|
render(resolved)
|
|
```
|
|
|
|
## `next/image` in tests
|
|
Use a simple `<img>` with `eslint-disable-next-line @next/next/no-img-element` — don't try to mock next/image.
|
|
|
|
## When writing tests
|
|
1. Read the component/function being tested first
|
|
2. Identify: happy path, error path, edge cases, SSR rendering
|
|
3. Mock ALL external API calls (Directus, n8n, PostgreSQL)
|
|
4. Run `npx jest path/to/test.tsx` to verify the specific test passes
|
|
5. Run `npm run test` to verify no regressions
|
|
6. Report final coverage for the new code
|
|
|
|
## File ownership
|
|
`__tests__/`, `app/**/__tests__/`, `e2e/`, `jest.config.ts`, `jest.setup.ts`
|
|
|
|
## E2E test files
|
|
`e2e/critical-paths.spec.ts`, `e2e/hydration.spec.ts`, `e2e/accessibility.spec.ts`, `e2e/performance.spec.ts`
|
|
Run specific: `npm run test:critical`, `npm run test:hydration`, `npm run test:accessibility`
