# Dependency graph
requires:
  - phase: 14-04
    provides: DefaultPhaseDispatchManager implementation
  - phase: 14-01
    provides: DrizzlePhaseRepository with dependency methods
provides:
  - Unit tests for PhaseRepository dependency methods
  - Unit tests for DefaultPhaseDispatchManager
  - Test coverage for phase dependency and dispatch logic
affects: [14-parallel-phase-execution]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - Mock EventBus pattern for capturing emitted events
    - Database test helpers extended for phase_dependencies table

key-files:
  created:
    - src/dispatch/phase-manager.test.ts
  modified:
    - src/db/repositories/drizzle/phase.test.ts
    - src/db/repositories/drizzle/test-helpers.ts

key-decisions:
  - "Added phase_dependencies table to test-helpers.ts for in-memory test database"
  - "Test patterns follow existing manager.test.ts and task.test.ts conventions"

patterns-established:
  - "Phase dispatch tests use same mock EventBus pattern as task dispatch"
  - "Dependency scenario tests verify diamond dependency ordering"

# Phase 14 Plan 07: Unit Tests for Phase Dependencies and Dispatch Summary

**Unit test coverage for PhaseRepository dependency methods and DefaultPhaseDispatchManager queue/dispatch logic with 46 new test cases**

## Performance

- **Duration:** 3 min
- **Started:** 2026-02-02T12:45:51Z
- **Completed:** 2026-02-02T12:48:43Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments

- Added 9 test cases for PhaseRepository dependency methods (createDependency, getDependencies, getDependents)
- Added 21 test cases for DefaultPhaseDispatchManager covering full dispatch lifecycle
- Added phase_dependencies table to test database setup for proper test isolation
- Diamond dependency scenario test verifies correct dispatch ordering

## Task Commits

Each task was committed atomically:

1. **Task 1: Add PhaseRepository dependency tests** - `26778c6` (test)
2. **Task 2: Add DefaultPhaseDispatchManager tests** - `1aac486` (test)

## Files Created/Modified

- `src/dispatch/phase-manager.test.ts` - New test file with 21 test cases for phase dispatch manager
- `src/db/repositories/drizzle/phase.test.ts` - Added 9 test cases for dependency methods
- `src/db/repositories/drizzle/test-helpers.ts` - Added phase_dependencies table to test schema

## Decisions Made

- Added phase_dependencies table to test-helpers.ts CREATE_TABLES_SQL to enable dependency testing in isolated in-memory databases
- Tests follow same mock EventBus pattern as existing manager.test.ts for consistency

## 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
- [x] New tests cover all new functionality from 14-01 and 14-04

## Next Phase Readiness

- Phase 14 now has full unit test coverage for phase dependencies and dispatch
- Ready for plan 14-08 (final plan of phase)
