public class SolrCloudTestCase
extends SolrTestCaseJ4

Base class for SolrCloud tests

Derived tests should call configureCluster(int) in a BeforeClass static method or Before setUp method. This configures and starts a MiniSolrCloudCluster, available via the cluster variable. Cluster shutdown is handled automatically if using BeforeClass.

   
   @BeforeClass
   public static void setupCluster() {
     configureCluster(NUM_NODES)
        .addConfig("configname", pathToConfig)
        .configure();
   }
