### Running Tests

```bash
# Run all tests
mvn test

# Run specific test class
mvn test -Dtest=CrawlerTest

# Run specific test method
mvn test -Dtest=CrawlerTest#test_execute_web

# Run tests for specific module
mvn test -pl fess-crawler
```

## Examples

        for (int i = 0; i < threadCount; i++) {
            executor.submit(new Runnable() {
                @Override
                public void run() {
                    try {
                        startLatch.await();

```

### Testing

The project uses JUnit 4 with embedded OpenSearch for integration testing:

```bash
# Run all tests
mvn test

# Run specific test class
mvn test -Dtest=SuggesterTest

# Run with verbose output
mvn surefire:test -Dmaven.surefire.debug=true
```

### Running Tests with Coverage
