TestScheduler

Scheduler with artificial time, useful for testing.

For example, you could test the Observable.interval operation using a TestScheduler as follows:

@Test def testInterval() {
  import org.mockito.Matchers._
  import org.mockito.Mockito._
  import rx.lang.scala.JavaConversions._

  val scheduler = TestScheduler()
  val observer = mock(classOf[rx.Observer[Long]])

  val o = Observable.interval(1 second, scheduler)
  val sub = o.subscribe(toScalaObserver(new TestObserver(observer)))

  verify(observer, never).onNext(0L)
  verify(observer, never).onCompleted()
  verify(observer, never).onError(any(classOf[Throwable]))

  scheduler.advanceTimeTo(2 seconds)

  val inOrdr = inOrder(observer);
  inOrdr.verify(observer, times(1)).onNext(0L)
  inOrdr.verify(observer, times(1)).onNext(1L)
  inOrdr.verify(observer, never).onNext(2L)
  verify(observer, never).onCompleted()
  verify(observer, never).onError(any(classOf[Throwable]))

  sub.unsubscribe();
  scheduler.advanceTimeTo(4 seconds)
  verify(observer, never).onNext(2L)
  verify(observer, times(1)).onCompleted()
  verify(observer, never).onError(any(classOf[Throwable]))
}

Retrieve or create a new rx.lang.scala.Worker that represents serial execution of actions.
Retrieve or create a new rx.lang.scala.Worker that represents serial execution of actions.
When work is completed it should be unsubscribed using unsubscribe.
Work on a rx.lang.scala.Worker is guaranteed to be sequential.
returns
