Example 2 with TaskHandler

use of io.zeebe.client.task.TaskHandler in project zeebe by zeebe-io.

the class TaskSubscriptionTest method shouldNotLoseCreditsOnFailureToReportTaskFailure.

/**
 * i.e. if signalling task failure itself fails
 */
@Test
public void shouldNotLoseCreditsOnFailureToReportTaskFailure() throws InterruptedException {
    // given
    broker.stubTaskSubscriptionApi(123L);
    failTaskFailure();
    final int subscriptionCapacity = 8;
    final AtomicInteger failedTasks = new AtomicInteger(0);
    final TaskHandler taskHandler = (c, t) -> {

    final RemoteAddress clientAddress = broker.getReceivedControlMessageRequests().get(0).getSource();
    for (int i = 0; i < subscriptionCapacity; i++) {
        broker.pushLockedTask(clientAddress, 123L, i, i, "owner", "foo");
    }
    // when
    TestUtil.waitUntil(() -> failedTasks.get() == 8);
    // give the client a bit of time to submit credits; this is not coupled to any defined event, so we just sleep for a bit
    Thread.sleep(500L);
    // then
    final List<ControlMessageRequest> creditRequests = getCreditRequests().collect(Collectors.toList());
    assertThat(creditRequests).isNotEmpty();
    final int numSubmittedCredits = creditRequests.stream().mapToInt((r) -> (int) r.getData().get("credits")).sum();
    assertThat(numSubmittedCredits).isGreaterThan(0);
}
