## 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();
}

          └────────────┘                                        │   KMS   │
                                                                └─────────┘
```

In a given setup, there are `n` MinIO instances talking to `m` KES servers but only `1` central KMS. The most simple setup consists of `1` MinIO server or cluster talking to `1` KMS via `1` KES server.

  private val fakeDns = FakeDns()
  private val recordingAuthenticator = RecordingAuthenticator()
  private val factory =
    TestValueFactory()
      .apply {
        dns = fakeDns
      }

  @BeforeEach
  fun setup() {
    Authenticator.setDefault(recordingAuthenticator)
  }

  @AfterEach
  fun tearDown() {
    Authenticator.setDefault(null)
    factory.close()
  }

  @Test
  fun testBasicAuth() {

    @Inject
    protected RepositorySystem system;

    @Inject
    protected PlexusContainer container;

    protected RepositorySystemSession session;

    @BeforeEach
    public void setUp() throws Exception {
        session = newMavenRepositorySystemSession(system);
    }

    protected PlexusContainer getContainer() {
        return container;
    }

## Your Environment
<!--- Include as many relevant details about the environment you experienced the bug in -->
* Version used (`minio --version`):
* Server setup and configuration:

The additional resource specific metrics which include additional go metrics or process metrics are exposed at
`<Address for MinIO Node>/minio/v2/metrics/resource`.

To use this endpoint, setup Prometheus to scrape data from this endpoint. Read more on how to configure and use Prometheus to monitor MinIO server in [How to monitor MinIO server with Prometheus](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/README.md).

 * This test covers URL parsing, connection state management, and thread-safety.
