TestScheduler

class TestScheduler extends Scheduler

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._

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

val o = Observable.interval(1 second, scheduler)
val sub = o.subscribe(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]))
}

  11. def createWorker: Worker

    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

    Inner representing a serial queue of actions to be executed
