Examples with InstanceStateEvent org.eclipse.che.api.machine.server.event.InstanceStateEvent used on opensource projects

Example 1 with InstanceStateEvent

use of org.eclipse.che.api.machine.server.event.InstanceStateEvent in project che by eclipse.

the class CheEnvironmentEngineTest method shouldDestroyAndRemoveMachineFromEnvironmentIfEventAboutItsDeath.

@Test
public void shouldDestroyAndRemoveMachineFromEnvironmentIfEventAboutItsDeath() throws Exception {
    // given
    List<Instance> instances = startEnv();
    Instance instance = instances.get(0);
    String machineId = instance.getId();
    String workspaceId = instance.getWorkspaceId();
    when(instance.getLogger()).thenReturn(LineConsumer.DEV_NULL);
    engine.init();
    verify(eventService).subscribe(eventServiceSubscriberCaptor.capture());
    EventSubscriber<InstanceStateEvent> subscriber = eventServiceSubscriberCaptor.getValue();
    ArgumentCaptor<Runnable> runnableArgumentCaptor = ArgumentCaptor.forClass(Runnable.class);
    // when
    subscriber.onEvent(new InstanceStateEvent(machineId, workspaceId, InstanceStateEvent.Type.DIE));
    // catch event actor
    verify(sharedPool).execute(runnableArgumentCaptor.capture());
    Runnable eventActor = runnableArgumentCaptor.getValue();
    // run event actor to verify its behavior
    eventActor.run();
    // then
    for (Instance instance1 : instances) {
        // other machines are not destroyed
        if (instance1.equals(instance)) {
            verify(instance1).destroy();
        } else {
            verify(instance1, never()).destroy();
        }
    }
    for (Instance instance1 : engine.getMachines(workspaceId)) {
        assertNotEquals(instance1.getId(), machineId);
    }
}
