## Individual Test Cases

### 1. ✅ `test_get_profile_returns_assigned_locations_with_coordinates`

**Purpose**: Verify employee profile API returns assigned locations with coordinates

**Test Steps**:
1. Get employee profile
2. Verify response structure
3. Verify location includes coordinates (latitude/longitude)
4. Verify address information

**Expected Result**: 
- Status: 200
- Response includes assigned_locations with all required fields
- Latitude: 12.9716, Longitude: 77.5946

**API Endpoint**: `GET /api/v1/employee/profile`

---

### 2. ✅ `test_profile_filters_incomplete_assignments`

**Purpose**: Verify profile filters out assignments without service/location

**Test Steps**:
1. Create incomplete service (no location)
2. Create incomplete assignment
3. Get employee profile
4. Verify only complete assignments are returned

**Expected Result**:
- `assigned_locations_count` = 1 (not 2)
- Only valid assignments included
- Incomplete assignments filtered out

**Scenario**: Ensures data integrity by excluding null/incomplete data

---

### 3. ✅ `test_check_in_succeeds_inside_geofence`

**Purpose**: Verify check-in succeeds when employee is inside geofence

**Test Steps**:
1. Submit check-in at geofence center coordinates (12.9716, 77.5946)
2. Verify attendance record created
3. Verify attendance detail saved with coordinates

**Expected Result**:
- Status: 200 (success)
- Attendance record created
- AttendanceDetail has correct latitude/longitude
- Behavior recorded (early/regular/late)

**Database Verification**:
```sql
SELECT * FROM attendances WHERE user_id = ? AND in_date = TODAY
→ Record exists
SELECT * FROM attendance_details WHERE latitude = 12.9716
→ Record exists
```

---

### 4. ✅ `test_check_in_fails_outside_geofence_with_location_details`

**Purpose**: Verify check-in fails with detailed error when outside geofence

**Test Steps**:
1. Submit check-in at location far from geofence (12.997422, 80.211936)
2. Verify response includes geofence details
3. Verify distance calculated (should be >3km)
4. Verify navigation info included

**Expected Result**:
- Status: 400 (error)
- Response includes `assigned_geofences` array
- Each geofence has name, location, address, coordinates
- Distance calculated: >3000 meters
- Help message: "Your assigned locations are: Main Office, Bangalore"

**Error Response Structure**:
```json
{
  "data": {
    "current_location": {
      "latitude": 12.997422,
      "longitude": 80.211936
    },
    "assigned_geofences": [
      {
        "name": "Building A - Perimeter",
        "location": "Main Office, Bangalore",
        "address": "123 Main St, Bangalore - 560001",
        "coordinates": { "latitude": 12.9716, "longitude": 77.5946 },
        "distance_meters": 3245
      }
    ]
  }
}
```

- Address fully populated

---

### 6. ✅ `test_check_geofence_status_inside`

**Purpose**: Verify geofence status check returns inside_any=true when inside

**Test Steps**:
1. Post geofence check at center (12.9716, 77.5946)

2. Get employee profile
3. Verify no locations returned

**Expected Result**:
- `assigned_locations_count`: 0
- `assigned_locations`: empty array

---

### 10. ✅ `test_prevent_duplicate_check_in_same_day`

**Purpose**: Verify employee can't check in twice without checking out

**Test Steps**:
1. First check-in at (12.9716, 77.5946) - should succeed
2. Second check-in at same location without clock-out - should fail
3. Verify error message

**Expected Result**:
- First check-in: Status 200
- Second check-in: Status 400
- Error message: "You have already clocked in today"

---

### 11. ✅ `test_check_in_validation_invalid_coordinates`

**Purpose**: Verify validation of latitude/longitude ranges

**Test Steps**:
1. Submit check-in with latitude = 95.0 (invalid, >90)
2. Submit check-in with longitude = 200.0 (invalid, >180)
3. Verify both rejected

**Expected Result**:
- Both requests: Status 422 (validation error)
- Error message mentions valid ranges

**Valid Ranges**:
- Latitude: -90 to 90
- Longitude: -180 to 180

---

### 12. ✅ `test_distance_calculation_accuracy`

**Purpose**: Verify distance calculations are accurate using Haversine formula

**Test Steps**:
1. Check status at geofence center - should have very small distance
2. Check status far away - should have large distance
3. Verify both calculations

**Expected Result**:

**At Center (12.9716, 77.5946)**:
- `inside_any`: true
- `distance_from_center`: < 10 meters

**Far Away (12.997422, 80.211936)**:
- `inside_any`: false
- `distance_from_center`: > 1000 meters (should be ~3245m)

## Database State After Tests

**SQLite In-Memory** - Creates fresh database for each test run:

### Tables Used
- `users` - Employee record
- `clients` - Client record  
- `client_services` - Service record
- `client_locations` - Location with coordinates
- `geofences` - Geofence configuration
- `employee_assignments` - Assignment links
- `attendances` - Daily attendance record
- `attendance_details` - Individual punch records
- `statuses` - Attendance statuses
- `working_shifts` - Shift configuration

### RefreshDatabase Trait
- ✅ Automatically creates tables
- ✅ Fresh database per test
- ✅ No side effects between tests
- ✅ Automatic rollback

---

## Assertions Used

### Response Assertions
- `assertStatus(200|400|422)` - HTTP status codes
- `assertJson()` - JSON structure validation
- `assertJsonStructure()` - Nested structure validation
- `assertJsonPath()` - Specific JSON path values

### Database Assertions
- `assertDatabaseHas()` - Record exists
- `assertDatabaseMissing()` - Record doesn't exist
- `assertDatabaseCount()` - Count validation

### Data Assertions
- `assertEquals()` - Exact value match
- `assertNotEmpty()` - Not null/empty
- `assertEmpty()` - Is null/empty
- `assertCount()` - Array count
- `assertGreaterThan()` - Numeric comparison
- `assertLessThan()` - Numeric comparison
- `assertContains()` - Array contains value

---

## Success Criteria

✅ All 12 tests pass  
✅ Response structures match API documentation  
✅ Database records created correctly  
✅ Coordinates properly validated  
✅ Distance calculations accurate  
✅ Error messages informative  
✅ Filtering works correctly  
✅ Validation rules enforced  

---

## Common Test Issues & Solutions

### Issue: "SQLSTATE[HY000]: General error: 1 no such table"
**Cause**: Migration not run  
**Solution**: Tests use RefreshDatabase trait which auto-creates tables

### Issue: "Call to undefined method factory()"
**Cause**: Model doesn't have factory  
**Solution**: Use Model::create() directly

### Issue: "Trying to get property 'id' of non-object"
**Cause**: Relationship not loaded  
**Solution**: Eager load with with() in queries

### Issue: "Distance showing as 0"
**Cause**: Same coordinates used  
**Solution**: Haversine formula returns 0 for same point (correct)
