2.x: BaseObserver.assertOnlyValues(T...)

I’d like to introduce assertOnlyValues to the BaseObserver. It’s the counterpart to assertResult(T...) which does almost the same except for the fact that the type hasn’t completed yet.

I’m open if anyone has a better function name. Internally it’d delegate to:

  assertValues(values)
      .assertNoErrors()
      .assertNotComplete()
      .assertSubscribed();

Okay, let’s add it.

I’d name it assertValuesOnly so it should show up right after assertValues in code completion.

For sure, I’m also pretty sure @vanniktech uses Kotlin so he could add extension function.

That’s what I’m doing right now. However I still think a lot of other people could benefit from this and the cost of adding this is really low.

Not a fan of naming though, but I see the pattern, assertOnlyValues() should fit test API design.

Open for any better name.
