Example 1 with ProgramControllerServiceAdapter

use of io.cdap.cdap.internal.app.runtime.ProgramControllerServiceAdapter in project cdap by caskdata.

the class ProgramControllerTest method testInitState.

@Test
public void testInitState() throws ExecutionException, InterruptedException {
    // To test against race-condition, we start/stop service multiple times.
    // If there is race, there is a chance that this test will fail in some env.
    // Otherwise it should always pass

    int serviceCount = 1000;
    final CountDownLatch latch = new CountDownLatch(serviceCount);
    ProgramId programId = new ApplicationId(NamespaceId.DEFAULT.getNamespace(), "test").service("test");
    for (int i = 0; i < serviceCount; i++) {
        // Creates a controller for a guava service do nothing in start/stop.
        // The short time in start creates a chance to have out-of-order init() and alive() call if there is a race.
        Service service = new TestService(0, 0);
        ProgramController controller = new ProgramControllerServiceAdapter(service, programId.run(RunIds.generate()));
