# Dependency graph
|
|
requires:
|
|
- phase: 01-foundation
|
|
provides: SvelteKit project structure with vite.config.ts
|
|
provides:
|
|
- Multi-project Vitest configuration (browser + node modes)
|
|
- SvelteKit module mocks ($app/navigation, $app/stores, $app/environment)
|
|
- Test scripts (test, test:unit, test:coverage)
|
|
- Coverage reporting with v8 provider

key-decisions:

|
|
- "Coverage thresholds with autoUpdate initially (no hard threshold yet)"

|
- "SvelteKit mocks use simple vi.mock, not importOriginal (avoids SSR issues)"

|
|
|
patterns-established:
|
|
- "*.svelte.test.ts for component tests (browser mode)"

- "*.test.ts for utility/server tests (node mode)"

# Phase 9 Plan 1: Vitest Infrastructure Summary
|
|
|
|
**Multi-project Vitest configuration with browser mode for Svelte 5 components and node mode for server/utility tests**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 3 min
|
|
- **Started:** 2026-02-03T22:27:09Z
|
|
- **Completed:** 2026-02-03T22:29:58Z
|
|
- **Tasks:** 3
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
- Vitest installed and configured with multi-project setup
|
|
- Browser mode ready for Svelte 5 component tests (via Playwright)
|
|
- Node mode ready for server/utility tests
|
|
- SvelteKit module mocks ($app/*) for test isolation
|
|
- Coverage reporting functional (v8 provider, autoUpdate thresholds)
|
|
- 17 unit tests proving infrastructure works
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Install Vitest dependencies and configure multi-project setup** - `a3ef94f` (feat)
|
|
2. **Task 2: Create SvelteKit module mocks in setup file** - `b0e8e4c` (feat)
|
|
3. **Task 3: Write sample test to verify infrastructure** - `b930f18` (test)
|
|
|
|
## Files Created/Modified
|
|
- `vite.config.ts` - Multi-project Vitest config (client browser mode + server node mode)
|
|
- `vitest-setup-client.ts` - SvelteKit module mocks for browser tests
|
|
- `package.json` - Test scripts (test, test:unit, test:unit:watch, test:coverage)
|
|
- `src/lib/utils/filterEntries.test.ts` - Sample unit test with 17 test cases, 100% coverage
|
|
|
|
## Decisions Made
|
|
- Used v8 coverage provider (10x faster than istanbul, equally accurate since Vitest 3.2)
|
|
- Set coverage thresholds to autoUpdate initially - Plan 02 will enforce 80% threshold
|
|
- Browser mode uses Playwright provider (real browser via Chrome DevTools Protocol)
|
|
- SvelteKit mocks are simple vi.fn() implementations, not importOriginal (causes SSR issues per research)
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
|
|
None
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Test infrastructure ready for Plan 02 (coverage thresholds, CI integration)
|
|
- Component test infrastructure ready but no component tests yet (Plan 03 scope)
|
|
- filterEntries.test.ts demonstrates node-mode test pattern
