|
||||
- ✅ Quiz type validation (practice, timed, exam)
|
||||
- ✅ Random question selection from category
|
||||
- ✅ Difficulty filtering applied (or mixed for all difficulties)
|
||||
- ✅ Handles insufficient questions gracefully
|
||||
- ✅ Total points calculated from selected questions
|
||||
- ✅ Time limit set for timed/exam quizzes (2 minutes per question)
|
||||
- ✅ Quiz session created with in_progress status
|
||||
- ✅ Junction records created for quiz-question linkage
|
||||
- ✅ Questions ordered sequentially (1-based)
|
||||
- ✅ Correct answers NOT exposed in response
|
||||
- ✅ Transaction rollback on errors
|
||||
- ✅ UUID validation for category IDs
|
||||
- ✅ Proper error handling and status codes
|
||||
- ✅ All 20 tests passing (user quizzes, guest quizzes, validation, structure)
|
||||
|
||||
#### Implementation Notes:
|
||||
- Created `models/QuizSessionQuestion.js` for junction table (58 lines)
|
||||
- Added `controllers/quiz.controller.js` with startQuizSession function (274 lines)
|
||||
- Created `routes/quiz.routes.js` with dual authentication middleware (58 lines)
|
||||
- Registered quiz routes in server.js at `/api/quiz`
|
||||
- Dual auth middleware: tries user JWT first, then guest token using async/await with Promise wrapping
|
||||
- Fixed guest middleware to set both `req.guestId` (string) and `req.guestSessionId` (UUID for foreign keys)
|
||||
- Fixed time limit to be stored in seconds (model validation requires min 60 seconds)
|
||||
- Time limit calculation: totalQuestions × 2 minutes × 60 seconds = 120 seconds per question
|
||||
- Time limit displayed in response as minutes for better UX
|
||||
- Transaction ensures atomic quiz creation with rollback on errors
|
||||
- Random question selection via `sequelize.random()`
|
||||
- Questions returned with sequential order (1, 2, 3...)
|
||||
- Guest limit enforcement integrated into quiz start flow
|
||||
- Category guestAccessible flag checked for guest users
|
||||
- Junction table stores questionOrder for maintaining quiz sequence
|
||||
- Response excludes correctAnswer, createdBy, and other sensitive fields
|
||||
- Test suite covers user quizzes (6 tests), guest quizzes (4 tests), validation (7 tests), structure (3 tests)

#### Implementation Details:
|
||||
- **Files Created**:
|
||||
- `controllers/user.controller.js` (252 lines)
|
||||
- `routes/user.routes.js` (13 lines)
|
||||
- `test-user-dashboard.js` (527 lines)
|
||||
- **Files Modified**:
|
||||
- `server.js` - Registered user routes at `/api/users`
|
||||
- `controllers/quiz.controller.js` - Fixed streak tracking logic
|
||||
|
||||
#### Features Implemented:
|
||||
- User information (username, email, role, profile image, member since)
|
||||
- Statistics (total quizzes, pass rate, accuracy, questions answered, streaks)
|
||||
- Recent 10 quiz sessions with category, scores, and time spent
|
||||
- Category-wise performance (quizzes taken, pass rate, accuracy per category)
|
||||
- Recent activity (daily quiz counts for last 30 days)
|
||||
- Streak status calculation (active if quiz today, at-risk if last active yesterday, inactive otherwise)
|
||||
|
||||
#### Bug Fixes:
|
||||
- Fixed field name mapping: `lastQuizDate` instead of `lastActiveDate`
|
||||
- Removed non-existent `percentage` field, calculating from `score/totalPoints`
|
||||
- Fixed authorization order: check user existence before authorization (proper 404 responses)
|
||||
- Fixed streak logic: update `longestStreak` when resetting `currentStreak`
|
||||
|
||||
#### Test Results:
|
||||
✅ All 14/14 tests passing:
|
||||
- Dashboard data retrieval

- Users can only access their own dashboard (authorization enforced)
|

- Streak calculation: active if quiz completed today, at-risk if last active yesterday, inactive otherwise
|

- Category performance uses SQL aggregation for efficiency
|
||||
- Recent activity limited to last 30 days

#### Bug Fixes During Testing:
|
||||
1. Fixed field names for quiz submission:
|
||||
- Changed `selectedOption` → `userAnswer`
|
||||
- Changed `timeTaken` → `timeSpent`
|
||||
- Used `quizSessionId` for submit endpoint
|
||||
2. Fixed complete quiz endpoint field:
|
||||
- Used `sessionId` (not `quizSessionId`) for complete endpoint
|
||||
|
||||
#### Files Modified:
|
||||
- ✅ `controllers/user.controller.js` - Added getQuizHistory function (485 lines total)
|
||||
- ✅ `routes/user.routes.js` - Added history route (27 lines total)
|
||||
- ✅ `test-quiz-history.js` - Created comprehensive test suite (552 lines)
|
||||
|
||||
#### Notes:
|
||||
- Users can only access their own quiz history (enforced by verifyToken and authorization check)
|
||||
- Date filtering supports ISO 8601 format (e.g., "2025-11-12" or "2025-11-12T10:00:00Z")
|
||||
- End date filter includes the entire day (00:00:00 to 23:59:59.999)
|
||||
- Default sorting is by most recent first (date descending)
|
||||
- Maximum 50 items per page to prevent performance issues
|
||||
- Empty result sets return empty array with correct pagination metadata
|
||||
- All validation errors return 400 with descriptive messages
|
||||
- Authorization errors return 403, missing resources return 404

||||
|
||||
#### API Endpoint:
|
||||
```
|
||||
PUT /api/users/:userId
|
||||
```
|
||||
|
||||
#### Implementation Details:
|
||||
- **Controller**: `controllers/user.controller.js` - Added `updateUserProfile` function (87 lines)
|
||||
- **Route**: `routes/user.routes.js` - Added PUT /:userId with verifyToken middleware
|
||||
- **Tests**: `test-update-profile.js` - 21 comprehensive test scenarios (all passing)
|
||||
- **Authorization**: Users can only update their own profile (userId must match JWT token)
|
||||
- **Features Implemented**:
|
||||
- Username update: Alphanumeric only, 3-50 chars, uniqueness check
|
||||
- Email update: Format validation, uniqueness check
|
||||
- Password update: Requires currentPassword verification, min 6 chars, bcrypt hashing via model hook
|
||||
- Profile image: URL string (max 255 chars), nullable
|
||||
- **Validation**: UUID format, field requirements, format checks, uniqueness constraints
|
||||
