Assertions are not failing in onErrorReturn rx java

I am having following code:

public Single<Post> doSomething(Post post) {
    String endPoint = "some-url";
    JsonObject payload = new JsonObject().put("message", post.getPost());
    return oAuth.rxApi(HttpMethod.POST, endPoint, payload)
            .map(r -> {
                post.setPostId(r.getString("id"));
                post.setStatus(PostStatus.PROCESSED);
                return post;
            }).onErrorReturn(e -> {
                post.setStatus(PostStatus.FAILED);
                post.setError(e.getMessage());
                return post;
            });
}

And I have written following test case for it.

@Test
public void shouldHandleFailureWhilePosting() {
    Post post = new Post();
    post.setSocialAccountID("1234");
    post.setAccessToken("ABC");
    post.setPost("Some post to share!!!");

    String shareEndPoint = "some-url";
    JsonObject sharePayload = new JsonObject().put("message", post.getPost());
    when(oAuth2Auth.rxApi(HttpMethod.POST, shareEndPoint, sharePayload)).thenReturn(Single.error(new NoStackTraceThrowable("Error")));

    service.doSomething(post)
            .subscribe(postResponse -> {
                assert postResponse.getError().equals("Errorssss");
                assert postResponse.getAttachedMedia() == null;
                assert postResponse.getPostId() == null;
                assert postResponse.getStatus().equals(PostStatus.FAILED);
            });
}

Now my assertions in this case always pass. Even if I make a wrong assertion, it is always green.

Have you enabled assertion checks with the -ea option?

Assertion, by default, are disabled ... Also, testing framework usually expose own "asserts" methods. For instance, on jUnit (org.junit.Assert), you may find static assertTrue(), assertArrayEquals(), assertNull() and so on

Assertions are executed in the context of the observable chain, and won't be directly accessible from your tests.

Instead use a TestSubscriber to subscribe to the observable chain. It has a number of assertions on it.
