Phase 9 Plan 2: Unit & Component Tests Summary

Comprehensive utility function tests and browser-mode component tests establishing testing patterns for the codebase

Performance

• Duration: 4 min
• Started: 2026-02-03T23:32:00Z
• Completed: 2026-02-03T23:37:00Z
• Tasks: 3
• Files modified: 6

Accomplishments

• All 3 utility functions (filterEntries, highlightText, parseHashtags) have 100% test coverage
• 3 Svelte 5 components tested with browser-mode pattern (SearchBar, TagInput, CompletedToggle)
• 94 total tests passing (76 server/node mode, 18 client/browser mode)
• Coverage thresholds configured to prevent regression

Task Commits

Each task was committed atomically:

1. Task 1: Write unit tests for utility functions - 20d9ebf (test)
2. Task 2: Write browser-mode component tests - 43446b8 (test)
3. Task 3: Configure coverage thresholds - d647308 (chore)

Files Created/Modified

• src/lib/utils/highlightText.test.ts - 24 tests for text highlighting
• src/lib/utils/parseHashtags.test.ts - 35 tests for hashtag parsing
• src/lib/components/CompletedToggle.svelte.test.ts - 5 tests for toggle component
• src/lib/components/SearchBar.svelte.test.ts - 7 tests for search input
• src/lib/components/TagInput.svelte.test.ts - 6 tests for tag selector
• vitest-setup-client.ts - Added mocks for $app/state, preferences, recentSearches
• vite.config.ts - Configured coverage thresholds

Test Coverage

Category	Statements	Branches	Functions	Lines
Overall	11.9%	6.62%	23.72%	9.74%
Utils	100%	100%	100%	100%
Threshold	10%	5%	20%	8%

Decisions Made

• Coverage thresholds below current levels - Set to prevent regression while allowing incremental improvement toward 80% target
• Centralized mocks in setup file - Avoids vi.mock hoisting issues in individual test files
• vitest/browser import - Updated from deprecated @vitest/browser/context

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• vi.mock hoisting - Factory functions cannot use external variables; mocks moved to setup file
• page.locator not available - Used render() return value or page.getByRole/getByText instead
• Deprecated import warning - Fixed by using 'vitest/browser' instead of '@vitest/browser/context'

User Setup Required

None - test infrastructure is fully configured.

Next Phase Readiness

• Test infrastructure proven with both browser and node modes
• Component testing pattern documented for future test authors
• Coverage thresholds active to prevent regression
• Ready for E2E tests (09-03) and CI pipeline integration (09-04)
