Example 1 with Topic

use of io.spine.client.Topic in project core-java by SpineEventEngine.

the class SubscriptionServiceShould method activate_subscription.

@Test
public void activate_subscription() {

    subscriptionObserver.verifyState();
    // Activate subscription
    final MemoizeStreamObserver<SubscriptionUpdate> activationObserver = new MemoizeStreamObserver<>();

    final int version = 1;
    final VersionableEntity entity = mockEntity(projectId, projectState, version);
    boundedContext.getStand().post(entity, requestFactory.createCommandContext());
    // isCompleted set to false since we don't expect activationObserver::onCompleted to be called.
    activationObserver.verifyState(false);
