### 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

  testImplementation(libs.junit.jupiter.params)
}

graalvmNative {
  testSupport = true

  binaries {
    named("test") {
      buildArgs.add("--strict-image-heap")

      // speed up development testing
      buildArgs.add("-Ob")
    }
