Phase 5 Plan 03: Act() Warning Elimination Summary

Migrated BackendSelectionStep.test.tsx to userEvent v14 and added vi.useFakeTimers() to ReviewStep.test.tsx, eliminating all act() warnings from both test suites

Performance

• Duration: 3 min
• Started: 2026-03-30T07:40:33Z
• Completed: 2026-03-30T07:43:41Z
• Tasks: 2
• Files modified: 2

Accomplishments

• Replaced all fireEvent.click / fireEvent.change calls in BackendSelectionStep.test.tsx with userEvent.setup() + await user.click() / await user.type()
• Added vi.useFakeTimers() to ReviewStep's beforeEach and vi.useRealTimers() to a new afterEach block
• Full suite: 104 tests passing across 12 test files with zero act() warnings and zero TypeScript errors

Task Commits

Each task was committed atomically:

1. Task 1: Migrate BackendSelectionStep.test.tsx from fireEvent to userEvent - 9b6d8a8 (feat)
2. Task 2: Fix ReviewStep act() warnings with vi.useFakeTimers - 913cbe8 (feat)

Plan metadata: (docs commit — see final commit)

Files Created/Modified

• src/components/wizard/BackendSelectionStep.test.tsx - Replaced fireEvent import with userEvent; 5 tests converted to async with userEvent.setup() pattern
• src/components/wizard/ReviewStep.test.tsx - Added afterEach to imports, vi.useFakeTimers() in beforeEach, new afterEach(() => vi.useRealTimers())

Decisions Made

• Used user.clear() before user.type() in all input tests — userEvent.type() appends to existing value, so clear is required to avoid stale default values contaminating typed content
• Kept fireEvent removed entirely from BackendSelectionStep.test.tsx (not just partially replaced) — cleaner import, no risk of future misuse
• Added vi.useFakeTimers() to the existing beforeEach block (not a new one) per plan specification — avoids multiple beforeEach hooks

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None — both migrations were straightforward. All 10 BackendSelectionStep tests and all 15 ReviewStep tests passed on first run after migration.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• TECH-05 requirement satisfied: CI test output is now clean with zero act() warnings
• All 5 TECH-0x requirements (TECH-01 through TECH-05) are verified green in the full test suite
• Phase 05-tech-debt test infrastructure is fully act()-safe — patterns established for future test files in phases 6 and 7
