## Key Testing Patterns

### 1. Isolation Testing
Each component tested independently with mocks:
```java
mockDb = mock(DatabaseService.class);
mockDetector = mock(ObjectDetectionService.class);
service = new ImageProcessingService(mockDb, mockDetector);
```

### 2. Integration Testing
Components tested together for realistic scenarios:
```java
db → imageProcessor → detector → notifier
```

### 3. Concurrency Testing
Thread safety verified with parallel operations:
```java
Thread t1 = new Thread(() -> db.upsertLot(...));
Thread t2 = new Thread(() -> db.upsertLot(...));
t1.start(); t2.start();
```

### 4. Error Handling
Graceful degradation tested throughout:
```java
assertDoesNotThrow(() -> service.process(invalidInput));
```

## Running the Tests

### Run All Tests
```bash
mvn test
```

### Run Specific Test Class
```bash
mvn test -Dtest=ScraperDataAdapterTest
mvn test -Dtest=IntegrationTest
```

### Run Single Test Method
```bash
mvn test -Dtest=IntegrationTest#testCompleteScraperImportWorkflow
```

### Generate Coverage Report
```bash
mvn jacoco:prepare-agent test jacoco:report
```

## Test Data Cleanup
All tests use temporary databases that are automatically cleaned up:
```java
@AfterAll
void tearDown() throws Exception {
    Files.deleteIfExists(Paths.get(testDbPath));
}
```

## Integration Scenarios Covered

### Scenario 1: New Auction Discovery
1. External scraper finds new auction
2. Data imported via ScraperDataAdapter
3. Lots added to database
4. Images downloaded
5. Object detection runs
6. Notification sent to user

### Scenario 2: Bid Monitoring
1. Monitor checks API every hour
2. Detects bid increase
3. Updates database
4. Sends notification
5. User can place counter-bid

### Scenario 3: Closing Alert
1. Monitor checks closing times
2. Lot closing in < 5 minutes
3. High-priority notification sent
4. Flag updated to prevent duplicates
5. User can place final bid

### Scenario 4: Value Estimation
1. Images downloaded
2. YOLO detects objects
3. Labels saved to database
4. Value estimated (future feature)
5. Notification sent with estimate

## Notes

- All tests are independent and can run in any order
- Tests use in-memory or temporary databases
- No actual HTTP requests made (except in integration tests)
- YOLO models are optional (tests work in disabled mode)
- Notifications are tested but may not display in headless environments
- Tests document expected behavior for each component

## Future Test Enhancements

1. **Mock HTTP Server** for realistic image download testing
2. **Test Containers** for full database integration
3. **Performance Tests** for large datasets (1000+ auctions)
4. **Stress Tests** for concurrent monitoring scenarios
5. **UI Tests** for notification display (if GUI added)
6. **API Tests** for Troostwijk API integration
7. **Value Estimation** tests (when algorithm implemented)
