I use Java 8, Elasticsearch High level client 6.1.1 and Maven and want to write some integration tests.  
Here my java class for tests:

```
@ESIntegTestCase.ClusterScope(scope = ESIntegTestCase.Scope.SUITE, numDataNodes=1)
public class ElasticSearchServiceITest extends ESIntegTestCase {
}

```

I have added dependencies:

```
<dependency>
            <groupId>org.elasticsearch.test</groupId>
            <artifactId>framework</artifactId>
            <version>6.1.1</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.lucene</groupId>
            <artifactId>lucene-test-framework</artifactId>
            <version>7.1.0</version>
            <scope>test</scope>
        </dependency>

```

When I try to run my test - I see cuch errors:

```

Add @RunWith(class com.carrotsearch.randomizedtesting.RandomizedRunner.class) to your test class. Make sure your code accesses random contexts within @BeforeClass and @AfterClass boundary (for example, static test class initializers are not permitted to access random contexts).

```

What I'm doing wrong? I haven't added any functionality but get the error.
