Deprecated

Assertj-rx is now deprecated. In-order to test observabales, please use the TestSubscriber - more information on this can be found here. Whilst the current version still remains usable, there will no longer be any new development taking place.

AssertJ RxJava

AssertJ assertions for RxJava Observables.

This library extends AssertJ core with the aim of providing elegant assertions to test RxJava Observables. The current version of this library only provides assertions aimed at testing "cold" Observables. You will need to transform your Observable into a BlockingObservable before performing any assertion.

Feedback and contributions are very welcome.

##Examples

  • Assert that completes successfully without emitting any error:
assertThat(observable.toBlocking()).completes();
  • Assert that completes after emitting a single value "hello":
assertThat(observable.toBlocking())
    .completes()
    .emitsSingleValue("hello");
  • Assert that completes without emitting any value:
assertThat(observable.toBlocking())
    .completes()
    .emitsNoValues();
  • Assert that emits an error:
assertThat(observable.toBlocking()).fails();
  • Assert that emits an error of type IllegalArgumentException
assertThat(observable.toBlocking())
    .failsWithError(IllegalArgumentException.class);
  • Assert that completes after emitting three values that are exactly "a", "b" and "c":
assertThat(observable.toBlocking())
    .completes()
    .listOfValuesEmitted()
    .containsExactly("a", "b", "c");
  • Assert that fails after emitting "a" and "b":
assertThat(observable.toBlocking())
    .fails()
    .listOfValuesEmitted()
    .containsExactly("a", "b");
  • Assert that completes after emitting 10 values
assertThat(observable.toBlocking())
   .completes()
   .valuesCountIs(10);
