Solr 4.10.4 version unit testing

I am trying to add unit tests to the binaryResponseWriter. I am not using solrcloud. It is just a simple master-slave setup(4.10.4 version). There is no concept of zkclients as this is traditional master-slave setup. Problem is when I extend AbstractSolrTestCase and run unit tests, I see error as "java.lang.NoClassDefFoundError: org/apache/solr/common/cloud/SolrZkClient ".

How do I configure the unit test that it is master-slave setup and not to configure zkclients? Please any suggestions to write unitTests for this.

The test looks somewhat like below.

    public class SolrSearchConfigTest extends AbstractSolrTestCase {

    private SolrServer server;

    public String getSolrHome() {
        return "src/Collection";
    }

    @Before
    @Override
    public void setUp() throws Exception {
        super.setUp();
        server = new EmbeddedSolrServer(h.getCoreContainer(), h.getCore().getName());
    }
}
