## Testing

### Test Framework

JUnit 4 with opensearch-runner (embedded instance)

### Standard Test Setup

```java
@BeforeClass
public static void beforeClass() {
    runner = new OpenSearchRunner();
    runner.build(newConfigs().clusterName("TestCluster").numOfNode(1));
    client = runner.client();
}

    private NetServerEnum2 netServerEnum2;
    private Configuration realConfig;

    @BeforeEach
    void setUp() throws Exception {
        MockitoAnnotations.openMocks(this);
        // Use real configuration for most tests
        realConfig = new BaseConfiguration(false);
        // Mock configuration setup
        when(mockConfig.getTransactionBufferSize()).thenReturn(65535);
    }

    @Test

- **Java 21 features** - Switch expressions and pattern matching for reduced overhead
