# Dependency graph
requires:
  - phase: 14-06
    provides: CLI commands for phase dispatch
  - phase: 14-04
    provides: PhaseDispatchManager adapter implementation
provides:
  - E2E tests for parallel phase execution scenarios
  - TestHarness integration with PhaseDispatchManager
affects: [15-frontend-wireframes]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Phase dispatch testing via TestHarness (same pattern as task dispatch)
    - Diamond dependency pattern testing for phase graph

key-files:
  created:
    - src/test/e2e/phase-dispatch.test.ts
  modified:
    - src/test/harness.ts

key-decisions:
  - "PhaseDispatchManager wired into TestHarness following DispatchManager pattern"
  - "E2E tests cover 4 core scenarios: independent, sequential, diamond, blocked"

patterns-established:
  - "Phase E2E tests mirror task E2E test structure"
  - "Diamond dependency pattern validation (A -> B,C -> D)"

# Phase 14 Plan 08: E2E Tests for Phase Dispatch Summary

**E2E tests for parallel phase execution with dependency ordering, covering independent dispatch, sequential dependencies, diamond patterns, and blocked phases**

## Performance

- **Duration:** 3 min
- **Started:** 2026-02-02T13:47:00Z
- **Completed:** 2026-02-02T13:50:00Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- Added phaseDispatchManager to TestHarness wired with phaseRepository and eventBus
- Created 5 E2E tests covering parallel phase execution scenarios
- Verified independent phases dispatch in parallel
- Verified dependent phases wait for prerequisites
- Verified diamond dependency pattern (A -> B,C -> D)
- Verified blocked phases prevent dispatch and propagate down chain

## Task Commits

Each task was committed atomically:

1. **Task 2: Add phaseDispatchManager to TestHarness** - `38ee2d1` (feat)
2. **Task 1: Create phase dispatch E2E tests** - `03fefd8` (test)

## Files Created/Modified

- `src/test/harness.ts` - Added phaseDispatchManager property and wiring
- `src/test/e2e/phase-dispatch.test.ts` - New E2E test file with 5 tests

## Decisions Made

- PhaseDispatchManager added to TestHarness following exact pattern of DispatchManager
- E2E tests use direct repository/manager calls rather than fixtures (phases created inline for clarity)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Verification

- [x] `npm run build` succeeds without errors
- [x] `npm test` passes all 452 tests (including 5 new E2E tests)
- [x] E2E tests verify actual parallel behavior

## Next Phase Readiness

- Phase 14 parallel execution complete
- All E2E tests pass
- Ready for Phase 15 (Frontend Wireframes)
