Example 31 with Observer

use of io.reactivex.rxjava3.core.Observer in project RxJava by ReactiveX.

the class ObservableDebounceTest method debounceWithError.

@Test
public void debounceWithError() {
    Observable<String> source = Observable.unsafeCreate(new ObservableSource<String>() {

        @Override
        public void subscribe(Observer<? super String> observer) {
            observer.onSubscribe(Disposable.empty());
            Exception error = new TestException();
            // Should be published since "two" will arrive after the timeout expires.
            publishNext(observer, 100, "one");
            // Should be skipped since onError will arrive before the timeout expires.
            publishNext(observer, 600, "two");
            // Should be published as soon as the timeout expires.
            publishError(observer, 700, error);
        }
    });
    Observable<String> sampled = source.debounce(400, TimeUnit.MILLISECONDS, scheduler);
    sampled.subscribe(observer);
    scheduler.advanceTimeTo(0, TimeUnit.MILLISECONDS);
    InOrder inOrder = inOrder(observer);
    // 100 + 400 means it triggers at 500
    scheduler.advanceTimeTo(500, TimeUnit.MILLISECONDS);
    inOrder.verify(observer).onNext("one");
    scheduler.advanceTimeTo(701, TimeUnit.MILLISECONDS);
    inOrder.verify(observer).onError(any(TestException.class));
    inOrder.verifyNoMoreInteractions();
