How To Test Subscribe Error In Jasmine. I recently faced this problem, “how could i test my asynchronous subscription and how to test the code before and after subscription”. You need to return something with a subscribe method, as the component calls subscribe directly from login. Let’s test that our component performs correctly after the observable completes. Writing tests for services with internal state. Testing observables returned by services. Rxjs comes with a handy toolset to test observables using marble diagrams as explained above. It should show a success modal when the service responds successfully. To simulate an error correctly, we should use the throwerror function from rxjs, which creates an observable that simply emits an error. To fix that, we need to have a mock of subject, behaviorsubject, replaysubject, and asyncsubject, but it should behave as empty: What we want to test: (a|) // emits 'a' and completes immediately.
