|
||||
|
||||

|
||||
|
||||
## 1. Matching Algorithm Tests (19 tests)
|
||||
|
||||
**File:** `backend/src/__tests__/matching-algorithm.test.js`
|
||||
**Coverage:** 94.71% statements, 91.5% branches in `matching.js`
|
||||
|
||||
These tests verify the complete matching algorithm based on `matching-scenarios.md`.
|
||||
|
||||
### Phase 1: Fundamentals (TC1-3)
|
||||
|
||||
#### TC1: One dancer, one free recorder → simple happy path
|
||||
- **Scenario:** Basic 1:1 matching
|
||||
- **Expected:** Recorder assigned, status PENDING
|
||||
- **Verifies:** Basic algorithm functionality
|
||||
|
||||
#### TC2: No recorders available → NOT_FOUND
|
||||
- **Scenario:** Dancer with heat, but no other participants
|
||||
- **Expected:** Suggestion created with status NOT_FOUND
|
||||
- **Verifies:** Graceful handling of no-recorder situations
|
||||
|
||||
#### TC3: Only recorder is self → NOT_FOUND
|
||||
- **Scenario:** Dancer is the only potential recorder
|
||||
- **Expected:** NOT_FOUND (can't record yourself)
|
||||
- **Verifies:** Self-recording prevention
|
||||
|
||||
### Phase 2: Collision Detection (TC4-9)
|
||||
|
||||
#### TC4: Recorder dancing in same heat → cannot record
|
||||
- **Scenario:** Both dancer and recorder in heat 10
|
||||
- **Expected:** NOT_FOUND (collision)
|
||||
- **Verifies:** Same-heat collision detection
|
||||
|
||||
#### TC5: Recorder in buffer BEFORE dance → cannot record
|
||||
- **Scenario:** Dancer heat 9, Recorder heat 10
|
||||
- **Config:** `HEAT_BUFFER_BEFORE = 1`
|
||||
- **Expected:** NOT_FOUND (recorder needs prep time)
|
||||
- **Verifies:** Before-buffer collision detection
|
||||
|
||||
#### TC6: Recorder in buffer AFTER dance → cannot record
|
||||
- **Scenario:** Dancer heat 11, Recorder heat 10
|
||||
- **Config:** `HEAT_BUFFER_AFTER = 1`
|
||||
- **Expected:** NOT_FOUND (recorder needs rest time)
|
||||
- **Verifies:** After-buffer collision detection
|
||||
|
||||
#### TC7: No collision when heat outside buffer
|
||||
- **Scenario:** Dancer heat 12, Recorder heat 10
|
||||
- **Buffer:** ±1 means recorder busy in 9,10,11
|
||||
- **Expected:** SUCCESS (heat 12 is free)
|
||||
- **Verifies:** Correct buffer calculation
|
||||
|
||||
#### TC8: Collision between divisions in same slot
|
||||
- **Scenario:** scheduleConfig maps Novice and Intermediate to same slot
|
||||
- **Setup:** Dancer in Novice heat 1, Recorder dancing in Intermediate heat 1
|
||||
- **Expected:** NOT_FOUND (same time slot collision)
|
||||
- **Verifies:** scheduleConfig slot mapping
|
||||
|
||||
#### TC9: No collision when divisions in different slots
|
||||
- **Scenario:** Novice in slot 1, Advanced in slot 2
|
||||
- **Expected:** SUCCESS (different time slots)
|
||||
- **Verifies:** Multi-slot schedule handling
|
||||
|
||||
### Phase 3: Limits & Workload (TC10-11)
|
||||
|
||||
#### TC10: MAX_RECORDINGS_PER_PERSON is respected
|
||||
- **Scenario:** 4 dancers, 1 recorder
|
||||
- **Config:** `MAX_RECORDINGS_PER_PERSON = 3`
|
||||
- **Expected:** 3 assigned, 1 NOT_FOUND
|
||||
- **Verifies:** Per-person recording limit enforcement
|
||||
|
||||
#### TC11: Recording-recording collision (critical bug fix)
|
||||
- **Scenario:** 2 dancers in same heat, 1 recorder
|
||||
- **Expected:** 1 assigned, 1 NOT_FOUND
|
||||
- **Verifies:** Recorder can only handle one heat at a time
|
||||
|
||||
### Phase 4: Fairness & Tiers (TC12-16)
|
||||
|
||||
#### TC12: Higher fairnessDebt → more likely to record
|
||||
- **Scenario:** RecorderA (debt +10), RecorderB (debt 0)
|
||||
- **Formula:** `fairnessDebt = recordingsReceived - recordingsDone`
|
||||
- **Expected:** RecorderA chosen (higher debt = more obligation)
|
||||
- **Verifies:** Fairness algorithm prioritization
|
||||
|
||||
#### TC13: Location score beats fairness
|
||||
- **Scenario:** RecorderA (same city, debt 0) vs RecorderB (different country, debt 100)
|
||||
- **Expected:** RecorderA chosen
|
||||
- **Verifies:** Location > Fairness in priority hierarchy
|
||||
|
||||
#### TC14: Basic vs Supporter vs Comfort tier penalties
|
||||
- **Scenario:** 3 recorders with same location/stats, different tiers
|
||||
- **Penalties:** BASIC (0), SUPPORTER (-10), COMFORT (-50)
|
||||
- **Expected:** BASIC chosen
|
||||
- **Verifies:** Tier penalty system
|
||||
|
||||
#### TC15: Supporter chosen when Basic unavailable
|
||||
- **Scenario:** Basic has collision, Supporter free
|
||||
- **Expected:** Supporter chosen (penalty overridden by availability)
|
||||
- **Verifies:** Fallback tier selection
|
||||
|
||||
#### TC16: Comfort used as last resort
|
||||
- **Scenario:** Only Comfort available (Basic has collision)
|
||||
- **Expected:** Comfort chosen (better than NOT_FOUND)
|
||||
- **Verifies:** Last-resort matching
|
||||
|
||||
### Phase 5: Edge Cases (TC17-19)
|
||||
|
||||
#### TC17: Dancer with no heats is ignored
|
||||
- **Scenario:** Participant with competitorNumber but no EventUserHeat records
|
||||
- **Expected:** 0 suggestions generated
|
||||
- **Verifies:** Heat existence requirement
|
||||
|
||||
#### TC18: Multiple heats for one dancer - all assigned
|
||||
- **Scenario:** 1 dancer with 3 heats (different divisions), 2 recorders
|
||||
- **Expected:** All 3 heats get suggestions
|
||||
- **Verifies:** Load balancing across multiple recorders (2-1 or 1-2 distribution)
|
||||
|
||||
#### TC19: Incremental matching respects accepted suggestions
|
||||
- **Scenario:**
|
||||
1. Run 1: 2 heats → 2 PENDING suggestions
|
||||
2. Recorder accepts suggestion for heat A
|
||||
3. Run 2: Re-run matching
|
||||
- **Expected:**
|
||||
- Heat A: Still has ACCEPTED suggestion (preserved)
|
||||
- Heat B: Updated/new suggestion
|
||||
- **Verifies:** `saveMatchingResults` preserves accepted/completed suggestions
|
||||
|

|
||||
|
||||
## 2. Ratings & Stats Flow Tests (9 tests)
|
||||
|
||||
**File:** `backend/src/__tests__/ratings-stats-flow.test.js`
|
||||
**Purpose:** End-to-end workflow from matching to stat updates
|
||||
|
||||
### Test Flow
|
||||
|
||||
#### STEP 1-3: Setup
|
||||
- Create event with past registration deadline
|
||||
- Register 2 users (dancer + recorder)
|
||||
- Enroll users and declare heat
|
||||
|
||||
#### STEP 4: Matching
|
||||
- Run `runMatching()` → generates suggestions
|
||||
- Call `saveMatchingResults()` → persists to DB
|
||||
- **Verifies:** Matching algorithm integration
|
||||
|
||||
#### STEP 5: Suggestion Acceptance
|
||||
- Recorder accepts suggestion via API
|
||||
- **Verifies:** Auto match creation (`source: 'auto'`)
|
||||
|
||||
#### STEP 6a-6b: Double Rating (Critical Flow)
|
||||
|
||||
**STEP 6a:** First rating (dancer rates recorder)
|
||||
```javascript
|
||||
POST /api/matches/:slug/ratings
|
||||
{
|
||||
score: 5,
|
||||
comment: "Great recorder!",
|
||||
wouldCollaborateAgain: true
|
||||
}
|
||||
```
|
||||
- **Expected:** Match status → `IN_PROGRESS`
|
||||
- **Stats:** NOT updated yet (need both ratings)
|
||||
|
||||
**STEP 6b:** Second rating (recorder rates dancer)
|
||||
```javascript
|
||||
POST /api/matches/:slug/ratings
|
||||
{
|
||||
score: 4,
|
||||
comment: "Good dancer!",
|
||||
wouldCollaborateAgain: true
|
||||
}
|
||||
```
|
||||
- **Expected:**
|
||||
- Match status → `COMPLETED`
|
||||
- `statsApplied` → `true` (atomic update)
|
||||
- Stats updated **exactly once**:
|
||||
- `recorder.recordingsDone += 1`
|
||||
- `dancer.recordingsReceived += 1`
|
||||
|
||||
#### STEP 7: Idempotency Test
|
||||
- Try rating the same match again
|
||||
- **Expected:** Stats remain unchanged (double-counting prevention)
|
||||
|
||||
#### STEP 8: Manual Match Verification
|
||||
- Create manual match (`source: 'manual'`)
|
||||
- Exchange ratings
|
||||
- **Expected:** Stats NOT updated (only auto-matches affect fairness)
|
||||
|
||||
### Key Edge Cases Covered
|
||||
|
||||
✅ **Race Condition Prevention**
|
||||
```javascript
|
||||
// Atomic check-and-set in backend/src/routes/matches.js:961-995
|
||||
const updateResult = await prisma.match.updateMany({
|
||||
where: {
|
||||
id: match.id,
|
||||
statsApplied: false // Only update if not already applied
|
||||
},
|
||||
data: {
|
||||
status: MATCH_STATUS.COMPLETED,
|
||||
statsApplied: true
|
||||
}
|
||||
});
|
||||
|
||||
// Only winner of the race applies stats
|
||||
if (updateResult.count === 1) {
|
||||
await matchingService.applyRecordingStatsForMatch(fullMatch);
|
||||
}
|
||||
```
|
||||
|
||||
✅ **Source Filtering**
|
||||
```javascript
|
||||
// Only auto-matches update stats (backend/src/services/matching.js:679-701)
|
||||
if (match.source !== 'auto') {
|
||||
return; // Manual matches don't affect fairness
|
||||
}
|
||||
```
|
||||
|
||||
✅ **Transaction Safety**
|
||||
```javascript
|
||||
// Stats update is transactional
|
||||
await prisma.$transaction([
|
||||
prisma.user.update({
|
||||
where: { id: recorderId },
|
||||
data: { recordingsDone: { increment: 1 } }
|
||||
}),
|
||||
prisma.user.update({
|
||||
where: { id: dancerId },
|
||||
data: { recordingsReceived: { increment: 1 } }
|
||||
})
|
||||
]);
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 3. Matching Runs Audit Tests (6 tests)
|
||||
|
||||
**File:** `backend/src/__tests__/matching-runs-audit.test.js`
|
||||
**Purpose:** Verify audit trail and origin_run_id tracking
|
||||
|
||||
### TC1: Run assigns origin_run_id correctly
|
||||
- **Action:** Admin clicks "Run now"
|
||||
- **Verifies:**
|
||||
- MatchingRun record created (`trigger: 'manual'`, `status: 'success'`)
|
||||
- All suggestions get `origin_run_id = runId`
|
||||
- Stats recorded (`matchedCount`, `notFoundCount`)
|
||||
- Admin endpoint returns correct data
|
||||
|
||||
### TC2: Sequential runs create separate origin_run_ids
|
||||
- **Scenario:**
|
||||
1. Run #1 → 1 heat → suggestion S1 (`origin_run_id=1`, `status=PENDING`)
|
||||
2. Add 2nd dancer with heat
|
||||
3. Run #2 → 2 heats → suggestions S1', S2 (`origin_run_id=2`)
|
||||
|
||||
- **Expected Behavior (IMPORTANT):**
|
||||
- Run #2 **deletes** PENDING suggestions from Run #1
|
||||
- `GET /matching-runs/1/suggestions` → **0 results** (replaced)
|
||||
- `GET /matching-runs/2/suggestions` → **2 results**
|
||||
- Both have `origin_run_id = 2`
|
||||
|
||||
- **Why:** Incremental matching **intentionally** replaces old PENDING suggestions with fresh ones
|
||||
|
||||
### TC3: Accepted/completed suggestions preserve origin_run_id
|
||||
- **Scenario:**
|
||||
1. Run #1 → suggestion S1 (`status=PENDING`, `origin_run_id=1`)
|
||||
2. Recorder accepts → `status=ACCEPTED`
|
||||
3. Run #2 → re-run matching
|
||||
|
||||
- **Expected:**
|
||||
- S1 **still exists** with `status=ACCEPTED`
|
||||
- S1 **keeps** `origin_run_id=1` (doesn't change to 2!)
|
||||
- `GET /matching-runs/1/suggestions` → returns S1
|
||||
- `GET /matching-runs/2/suggestions` → 0 results (heat already has accepted)
|
||||
|
||||
- **Verifies:** Accepted/completed suggestions are preserved across re-runs
|
||||
|
||||
### TC4: Filter parameters (onlyAssigned, includeNotFound)
|
||||
|
||||
**Setup:** 4 dancers (heats well-spaced), 1 recorder (MAX=3)
|
||||
**Result:** 3 assigned + 1 NOT_FOUND
|
||||
|
||||
**Test 4.1:** `?onlyAssigned=true&includeNotFound=false` (default)
|
||||
```bash
|
||||
GET /api/admin/events/:slug/matching-runs/:runId/suggestions?onlyAssigned=true
|
||||
```
|
||||
- **Expected:** 3 suggestions (only assigned, NOT_FOUND filtered out)
|
||||
|
||||
**Test 4.2:** `?onlyAssigned=false&includeNotFound=true`
|
||||
```bash
|
||||
GET /api/admin/events/:slug/matching-runs/:runId/suggestions?includeNotFound=true
|
||||
```
|
||||
- **Expected:** 4 suggestions (all, including NOT_FOUND)
|
||||
|
||||
**Test 4.3:** Default behavior
|
||||
```bash
|
||||
GET /api/admin/events/:slug/matching-runs/:runId/suggestions
|
||||
```
|
||||
- **Expected:** 3 suggestions (`onlyAssigned=true` by default)
|
||||
|
||||
### TC5: Manual vs scheduler trigger differentiation
|
||||
- **Verifies:**
|
||||
- Manual API call → `trigger: 'manual'`
|
||||
- Scheduler cron → `trigger: 'scheduler'`
|
||||
- Status lifecycle: `running` → `success`/`failed`
|
||||
|
||||
### TC6: Failed runs are recorded in audit trail
|
||||
- **Scenario:** Event with 0 heats → matching returns 0 results
|
||||
- **Expected:**
|
||||
- MatchingRun created with `status: 'success'`
|
||||
- `matchedCount=0`, `notFoundCount=0`
|
||||
- Audit trail complete even for empty runs
|
||||
|

|
||||
|
||||
## 4. Incremental Matching Tests (5 tests)
|
||||
|
||||
**File:** `backend/src/__tests__/matching-incremental.test.js`
|
||||
|
||||
### Test Scenarios
|
||||
|
||||
1. **New suggestions replace PENDING**
|
||||
- Old PENDING deleted, new created
|
||||
|
||||
2. **ACCEPTED suggestions preserved**
|
||||
- Not deleted or overwritten in re-runs
|
||||
|
||||
3. **COMPLETED suggestions preserved**
|
||||
- No duplicates for finished matches
|
||||
|
||||
4. **New heats added after first run**
|
||||
- Get suggestions in next run
|
||||
|
||||
5. **Status workflow**
|
||||
- PENDING → ACCEPTED → match creation → COMPLETED
|
||||

## 5. Recording Stats Integration Tests (6 tests)
|
||||
|
||||
**File:** `backend/src/__tests__/recording-stats-integration.test.js`
|
||||
|
||||
### Test Scenarios
|
||||
|
||||
1. **Stats update after double rating**
|
||||
- Atomic update verification
|
||||
- Both sides checked
|
||||
|
||||
2. **Stats don't update for manual matches**
|
||||
- `source: 'manual'` → no stats change
|
||||
|
||||
3. **Stats affect next matching round**
|
||||
- High debt user gets priority
|
||||
- Fairness feedback loop works
|
||||
|
||||
4. **Multiple matches update stats correctly**
|
||||
- 3 matches → 3x updates
|
||||
- No race conditions
|
||||
|
||||
5. **Rejected suggestions don't affect stats**
|
||||
- REJECTED/NOT_FOUND → no impact
|
||||
|
||||
6. **Stats persistence**
|
||||
- Survive restart
|
||||
- Correctly read in subsequent rounds

## Key Implementation Files
|
||||
|
||||
### Core Logic
|
||||
- **Matching Algorithm:** `backend/src/services/matching.js` (94.71% coverage)
|
||||
- `runMatching()` - generates suggestions
|
||||
- `saveMatchingResults()` - persists with origin_run_id
|
||||
- `applyRecordingStatsForMatch()` - updates fairness stats
|
||||
|
||||
### API Endpoints
|
||||
- **Run Matching:** `POST /api/events/:slug/run-matching`
|
||||
- Creates MatchingRun audit record
|
||||
- Triggers matching algorithm
|
||||
- Updates run stats on completion/failure
|
||||
|
||||
- **Rating Endpoint:** `POST /api/matches/:slug/ratings` (`backend/src/routes/matches.js:850-1011`)
|
||||
- Atomic statsApplied check-and-set
|
||||
- Match completion on double-rating
|
||||
- Stats update via `applyRecordingStatsForMatch()`
|
||||
|
||||
- **Admin Audit:** `GET /api/admin/events/:slug/matching-runs/:runId/suggestions`
|
||||
- Filter by origin_run_id
|
||||
- Support `onlyAssigned` and `includeNotFound` params
|
||||
- Returns per-run statistics
|
||||
|
||||
### Database Schema (Prisma)
|
||||
```prisma
|
||||
model RecordingSuggestion {
|
||||
id Int @id @default(autoincrement())
|
||||
eventId Int
|
||||
heatId Int
|
||||
recorderId Int?
|
||||
status String // 'pending', 'accepted', 'completed', 'not_found'
|
||||
originRunId Int? // 🆕 Tracks which run created this suggestion
|
||||
createdAt DateTime
|
||||
updatedAt DateTime
|
||||
}
|
||||
|
||||
model MatchingRun {
|
||||
id Int @id @default(autoincrement())
|
||||
eventId Int
|
||||
trigger String // 'manual' or 'scheduler'
|
||||
status String // 'running', 'success', 'failed'
|
||||
startedAt DateTime
|
||||
endedAt DateTime?
|
||||
matchedCount Int?
|
||||
notFoundCount Int?
|
||||
errorMessage String?
|
||||
}
|
||||
|
||||
model Match {
|
||||
// ... other fields
|
||||
source String // 'auto' or 'manual'
|
||||
statsApplied Boolean @default(false) // Race condition prevention
|
||||
}
|
||||
|
||||
model User {
|
||||
// ... other fields
|
||||
recordingsDone Int @default(0) // Fairness tracking
|
||||
recordingsReceived Int @default(0) // Fairness tracking
|
||||
}
|
||||
```

## Edge Cases Covered
|
||||
|
||||
### ✅ Matching Algorithm
|
||||
- Self-recording prevention
|
||||
- Same-heat collisions
|
||||
- Buffer-based collisions (BEFORE/AFTER)
|
||||
- Schedule slot mapping
|
||||
- MAX_RECORDINGS enforcement
|
||||
- Recording-recording collisions
|
||||
- Fairness debt calculation
|
||||
- Tier penalty hierarchy
|
||||
- Location prioritization
|
||||
- Load balancing
|
||||
- Multiple heats per dancer
|
||||
- Incremental matching (preserve accepted)
|
||||
|
||||
### ✅ Stats Updates
|
||||
- Race conditions (atomic check-and-set)
|
||||
- Double-counting prevention (idempotency)
|
||||
- Source filtering (auto vs manual)
|
||||
- Transaction safety
|
||||
- Match completion workflow
|
||||
- Double-rating requirements
|
||||
|
||||
### ✅ Audit Trail
|
||||
- origin_run_id assignment
|
||||
- Sequential run behavior
|
||||
- PENDING vs ACCEPTED/COMPLETED handling
|
||||
- Filter parameters
|
||||
- Trigger differentiation
|
||||
- Empty run handling
|
||||
- Failed run recording
|
||||

|
||||
|
||||
## Test Data Isolation
|
||||
|
||||
All tests use:
|
||||
- Unique timestamps in emails/usernames
|
||||
- Cleanup in `afterAll()` hooks
|
||||
- Proper foreign key deletion order
|
||||
- Event-scoped data queries
|
||||
|
||||
**Example:**
|
||||
```javascript
|
||||
const dancer = await prisma.user.create({
|
||||
data: {
|
||||
email: `dancer-${Date.now()}@test.com`, // ✅ Unique per test run
|
||||
username: `dancer_${Date.now()}`,
|
||||
// ...
|
||||
}
|
||||
});
|
||||
```
|
||||

||||
## Future Test Improvements
|
||||
|
||||
Potential additions identified in review:
|
||||
|
||||
1. **Concurrent matching runs** - thread-safety testing
|
||||
2. **Database transaction failures** - rollback behavior
|
||||
3. **Deleted users/events** - cascade delete handling
|
||||
4. **Invalid scheduleConfig** - malformed data handling
|
||||
5. **Extreme data scenarios** - 1000+ dancers, performance testing
|
||||
6. **Time zone edge cases** - DST transitions, midnight boundaries
|
||||
7. **Rating validation** - score=0, very long comments, special characters
|
||||
8. **Match deletion** - compensating transactions for stats
