# Phase 8 Plan 01: GameDAGRouter Edge Cases Summary
|
|
|
|
**17 TDD tests validating GameDAGRouter edge cases, anchor filtering, repeat city handling, and canTransition time/distance boundaries**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 25 min
|
|
- **Started:** 2026-01-10T17:37:21Z
|
|
- **Completed:** 2026-01-10T18:02:00Z
|
|
- **Tasks:** 3 (Task 2 auto-completed - tests passed on first run)
|
|
- **Files modified:** 2
|
|
|
|
## Accomplishments
|
|
- Created 10 edge case tests covering empty inputs, single games, anchor filtering, and repeat city handling
|
|
- Added 7 canTransition boundary tests for time buffers and distance constraints
|
|
- Removed broken DayCardTests that referenced deleted types (cleanup)
|
|
- All 17 tests pass, validating GameDAGRouter correctness
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Create GameDAGRouterTests with edge case tests** - `a4db9a9` (test)
|
|
2. **Task 2: Fix any failing edge case tests** - N/A (all passed on first run)
|
|
3. **Task 3: Add canTransition boundary tests** - `02cb09f` (test)
|
|
|
|
**Plan metadata:** (pending)
|
|
|
|
## Files Created/Modified
|
|
- `SportsTimeTests/GameDAGRouterTests.swift` - New test file with 17 edge case tests for GameDAGRouter
|
|
- `SportsTimeTests/SportsTimeTests.swift` - Removed broken DayCardTests (types no longer exist)
|
|
|
|
## Decisions Made
|
|
- Used Swift Testing framework consistent with existing tests (ScenarioBPlannerTests)
|
|
- Test canTransition() logic indirectly through findRoutes() behavior rather than making it public
|
|
- Corrected initial borderline timing test (GameEndBuffer) after verifying actual haversine distances
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 3 - Blocking] Fixed pre-existing broken tests**
|
|
- **Found during:** Task 1 (running tests)
|
|
- **Issue:** SportsTimeTests.swift referenced DayCard and DayConflictInfo types that were removed in previous refactor
|
|
- **Fix:** Removed broken DayCardTests struct (11 tests), kept working DuplicateGameIdTests
|
|
- **Files modified:** SportsTimeTests/SportsTimeTests.swift
|
|
- **Verification:** Build succeeds, all tests run
|
|
- **Committed in:** 02cb09f (combined with Task 3)
|
|
|
|
**2. [Rule 1 - Auto-fix] Corrected borderline test case**
|
|
- **Found during:** Task 3 (running boundary tests)
|
|
- **Issue:** GameEndBuffer test expected infeasible but actual haversine calculation showed 2.45hr drive fits in 2.5hr window
|
|
- **Fix:** Adjusted test timing to be clearly infeasible (1.5hr available for 2.45hr drive)
|
|
- **Files modified:** SportsTimeTests/GameDAGRouterTests.swift
|
|
- **Verification:** Test now correctly validates buffer behavior
|
|
- **Committed in:** 02cb09f
|
|
|
|
### Deferred Enhancements
|
|
|
|
None - all tests pass, no issues logged.
|
|
|
|
---
|
|
|
|
**Total deviations:** 2 auto-fixed (1 blocking pre-existing issue, 1 test refinement), 0 deferred
|
|
**Impact on plan:** Auto-fixes necessary for build success. No scope creep.
|
|
|
|
## Issues Encountered
|
|
- Pre-existing test failure in ScenarioAPlannerSwiftTests (plan_StopDepartureDate_IsLastGameDate) - unrelated to this phase, not investigated
|
|
|
|
## Next Phase Readiness
|
|
- GameDAGRouter edge cases validated, ready for Plan 08-02 (performance with large datasets)
|
|
- Test patterns established for future DAG routing tests
|
|
- No blockers
