- Zero test flakiness

Patterns Established:
- Constructor injection mocking (TimeTrackingService)
- Metadata (JSON) field testing
- Time calculation validation
- Date range query testing
- Aggregation testing (SUM, COUNT)

Documentation:
- phase-3-done.md: Detailed implementation plan
- phase-3-summary.md: Comprehensive completion report

+
+### Success Criteria
+- ✅ All Activities methods tested (7 endpoints)
+- ✅ All Time Tracking methods tested (8 endpoints)
+- ✅ 85%+ test coverage on both modules
+- ✅ Activity creation validation
+- ✅ Time tracking calculations verified
+- ✅ User tracking validated
+- ✅ All tests passing

+
+## 📋 Modules to Test
+
+### **1. Activities** (Priority: High)
+**Current Coverage:** 0 tests
+**Target:** 30-35 tests
+
+**Endpoints/Methods:**
+1. `createActivity` - Log activity on cards
+2. `getActivitiesByCardId` - Get card activity history
+3. `getActivitiesByBoardId` - Get board-wide activities
+4. `getActivitiesByUserId` - Get user's activities
+5. `getActivitiesWithUserDetails` - Activities with user info
+6. `deleteActivity` - Remove activity logs
+7. `getActivityCount` - Count activities
+
+**Key Features to Test:**
+- Activity creation for different types (comment, move, assign, etc.)
+- Filtering by card/board/user
+- User details joins
+- Chronological ordering
+- Activity counting
+- Metadata handling (JSON fields)
+- Deletion logic
+- Empty result handling
+
+---
+
+### **2. Time Tracking** (Priority: High)
+**Current Coverage:** 0 tests
+**Target:** 35-40 tests
