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

Feedback and contributions are very welcome.

Examples

• Assert that completes successfully without emitting any error:

  java
  assertThat(observable.toBlocking()).completes();
  

• Assert that completes after emitting a single value "hello":

  java
  assertThat(observable.toBlocking())
  .completes()
  .emitsSingleValue("hello");
  

• Assert that completes without emitting any value:

  java
  assertThat(observable.toBlocking())
  .completes()
  .emitsNoValues();
  

• Assert that emits an error:

  java
  assertThat(observable.toBlocking()).fails();
  

• Assert that emits an error of type

  IllegalArgumentException

  java
  assertThat(observable.toBlocking())
  .failsWithError(IllegalArgumentException.class);
  

• Assert that completes after emitting three values that are exactly "a", "b" and "c":

  java
  assertThat(observable.toBlocking())
  .completes()
  .listOfValuesEmitted()
  .containsExactly("a", "b", "c");
  

• Assert that fails after emitting "a" and "b":

  java
  assertThat(observable.toBlocking())
  .fails()
  .listOfValuesEmitted()
  .containsExactly("a", "b");
  

• Assert that completes after emitting 10 values

  java
  assertThat(observable.toBlocking())
  .completes()
  .valuesCountIs(10);
