the class FailureHandlingResultSnapshotTest method testLocalFailureHandlingResultSnapshotCreation.

@Test

    final long rootCauseTimestamp = triggerFailure(rootCauseExecutionVertex, rootCause);
    triggerFailure(otherFailedExecutionVertex, otherFailure);
    final FailureHandlingResult failureHandlingResult = FailureHandlingResult.restartable(rootCauseExecutionVertex.getID(), rootCause, rootCauseTimestamp, StreamSupport.stream(executionGraph.getAllExecutionVertices().spliterator(), false).map(ExecutionVertex::getID).collect(Collectors.toSet()), 0L, false);
    final FailureHandlingResultSnapshot testInstance = FailureHandlingResultSnapshot.create(failureHandlingResult, this::getLatestExecution);
    assertThat(testInstance.getRootCause(), is(rootCause));
    assertThat(testInstance.getTimestamp(), is(rootCauseTimestamp));
    assertThat(testInstance.getRootCauseExecution().isPresent(), is(true));
    assertThat(testInstance.getRootCauseExecution().get(), is(rootCauseExecutionVertex.getCurrentExecutionAttempt()));
