Example 1 with HelixTaskExecutor

use of org.apache.helix.messaging.handling.HelixTaskExecutor in project helix by apache.

the class TestHelixTaskHandler method testInvocation.

@Test()
public void testInvocation() throws Exception {
    HelixTaskExecutor executor = new HelixTaskExecutor();
    System.out.println("START TestCMTaskHandler.testInvocation()");
    Message message = new Message(MessageType.STATE_TRANSITION, "Some unique id");
    message.setSrcName("cm-instance-0");
    message.setTgtSessionId("1234");
    message.setFromState("Offline");
    message.setToState("Slave");
    message.setPartitionName("TestDB_0");
    message.setMsgId("Some unique message id");
    message.setResourceName("TestDB");
    message.setTgtName("localhost");
    message.setStateModelDef("MasterSlave");
    message.setStateModelFactoryName(HelixConstants.DEFAULT_STATE_MODEL_FACTORY);
    MockMasterSlaveStateModel stateModel = new MockMasterSlaveStateModel();
    NotificationContext context;
    MockManager manager = new MockManager("clusterName");
    HelixDataAccessor accessor = manager.getHelixDataAccessor();
    StateModelDefinition stateModelDef = new StateModelDefinition(StateModelConfigGenerator.generateConfigForMasterSlave());
    Builder keyBuilder = accessor.keyBuilder();
    accessor.setProperty(keyBuilder.stateModelDef("MasterSlave"), stateModelDef);
    context = new NotificationContext(manager);
    CurrentState currentStateDelta = new CurrentState("TestDB");
    currentStateDelta.setState("TestDB_0", "OFFLINE");
    HelixStateTransitionHandler stHandler = new HelixStateTransitionHandler(null, stateModel, message, context, currentStateDelta);
    HelixTask handler;
    handler = new HelixTask(message, context, stHandler, executor);
    handler.call();
    AssertJUnit.assertTrue(stateModel.stateModelInvoked);
    System.out.println("END TestCMTaskHandler.testInvocation() at " + new Date(System.currentTimeMillis()));
