@Tag("MiniClusterOnly")
public abstract class SharedMiniClusterBase
extends AccumuloITBase
implements ClusterUsers

Integration-Test base class which starts one MAC for the entire Integration Test. This IT type is faster and more geared for testing typical, expected behavior of a cluster. For more advanced testing see AccumuloClusterHarness There isn't a good way to build this off of the AccumuloClusterHarness (as would be the logical place) because we need to start the MiniAccumuloCluster in a static BeforeAll-annotated method. Because it is static and invoked before any other BeforeAll methods in the implementation, the actual test classes can't expose any information to tell the base class that it is to perform the one-MAC-per-class semantics. Implementations of this class must be sure to invoke startMiniCluster() or startMiniClusterWithConfig(MiniClusterConfigurationCallback) in a method annotated with the BeforeAll JUnit annotation and stopMiniCluster() in a method annotated with the AfterAll JUnit annotation.
