Koin testing on Androidx with Activity

Question

I am trying to do some instrumented tests of a boilerplate code after migrating it to AndroidX. Note that before migration, all of them worked, but after, only unit tests work, the instrumented test crashes on Null Pointer exception, where it shouldnt.

Here is the errror:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'io.reactivex.Flowable io.reactivex.Flowable.subscribeOn(io.reactivex.Scheduler)' on a null object reference
02:55:31 V/InstrumentationResultParser: at org.buffer.android.boilerplate.data.interactor.FlowableUseCase.execute(FlowableUseCase.kt:26)
02:55:31 V/InstrumentationResultParser: at org.buffer.android.boilerplate.ui.browse.BrowseBufferoosViewModel.fetchBufferoos(BrowseBufferoosViewModel.kt:25)
02:55:31 V/InstrumentationResultParser: at org.buffer.android.boilerplate.ui.browse.BrowseActivity.onCreate(BrowseActivity.kt:40)

as you see, it's in the declaration of my "UseCase" in this case, get bufferoos. For reference, here is the class that fails:

GetBufferoos

Flowable Use case

Here is the test that fails

ActivityTest

Here is modules.kt for koin

Modules

So `bufferooRepository.getBufferoos()` returns `null`? Please show some relevant Koin code. — shkschneider, Jan 04 '19 at 15:01
Exactly, and I do not know why because in normal run everything works fine. Is it a problem with injecting ? — Lukas Anda, Jan 04 '19 at 15:02
Most likely. That's why I'd like you to show form Koin related code near that repository and its factory. — shkschneider, Jan 04 '19 at 15:03
@shkschneider i've edited my question with link to modules, that's where I wrap all things together — Lukas Anda, Jan 04 '19 at 15:06
I have a limited skill in Koin and fail to see the issue. I Simply upvoted your question as it seems legit — shkschneider, Jan 04 '19 at 16:20
@shkschneider oh, thanks then :) Well, I think I might have to just go away with other instrumentation tests — Lukas Anda, Jan 04 '19 at 16:35
