## 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();
}

@Before
public void before() {

 */

    static OpenSearchRunner runner;

    @Rule
    public final TestName testName = new TestName();

    @BeforeClass
    public static void beforeClass() throws Exception {
        runner = new OpenSearchRunner();
        runner.onBuild((number, settingsBuilder) -> {
            settingsBuilder.put("http.cors.enabled", true);

    static final String[] tagFieldNames = new String[] { "label", "virtual_host" };
    static final String roleFieldName = "role";

    @BeforeClass

        runner = new OpenSearchRunner();
        runner.onBuild((number, settingsBuilder) -> {
            settingsBuilder.put("http.cors.enabled", true);
