Tests with TP - Mockk
Hello !
I didn't find a solution in the others issues or in the samples.
I think this case can help the others developpers.
I'm trying to do some simple tests on my useCase and i use Mockk and jUnit.
I have an error in the injection of my object geocoder, this is the stacktrace of my error:

}
}
I install my modules in the application. My useCase is call in a viewModel which doesn't contain TP.
I also try to Inject my useCase directly in my test class but it's not working.
Does someone have an idea ?
Thank's !
Hi @ClaireGizard ,
I see a few problems there:
- Inside the test class, i see that you are calling
toothPickRule.inject(this), but I don't see any class being injected (the class under Test). - I cannot see
WeatherApplicationModulebeing installed inside the tests. Still, if you wanna use mocks for all your dependencies, you shouldn't need to install it. - Right now
ToothPickRuleonly grabs mocks from the annotations with name@Mock, supporting Mockito and EasyMock. Do you want to create an issue so we add support toMockK?
Anyway, to provide you a working code, I'd need to see the code that you are testing: GetAddressUseCase.
Hi @dlemures ! Sorry for my late response. I tried to find a solution by creating another simple project. I solved the first and the third problem but i didn't find a solution for the second.

@Claire, I think your mockito rule is useless ;), even if it doesn't change the behavior/issue.

Hi @ClaireGizard ,
Sorry for the late response, we have been quite busy releasing the 3rd version.
The error you are having is with mockK. It is trying to find a mock of Application to inject in the MainViewModel constructor, but you haven't defined any:
class MainViewModelTests {
@get:Rule
var toothPickRule = ToothPickRule(this, "test scope")
@get:Rule
var instantTaskExecutorRule = InstantTaskExecutorRule()
@InjectMockKs // <- USING MOCKK TO INJECT THE DEPENDENCIES
lateinit var mainViewModel: MainViewModel
@Before
fun before() {
MockKAnnotations.init(this) // <- YOU DONT HAVE ANY MOCK ANNOTATION
RxAndroidPlugins.setInitMainThreadSchedulerHandler { Schedulers.trampoline() }
toothPickRule.inject(this) // <- DOING NOTHING
}
}
Even though you are using toothPickRule.inject(this), you are not using TP to inject MainViewModel. You are using mockK instead. You need to use one or the other.
I've not used mockK before, but if you decide to with that option, I think that something like this should work:
class MainViewModelTests {
@get:Rule
var instantTaskExecutorRule = InstantTaskExecutorRule()
@MockK
lateinit var application: Application
@InjectMockKs
lateinit var mainViewModel: MainViewModel
@Before
fun before() {
MockKAnnotations.init(this)
RxAndroidPlugins.setInitMainThreadSchedulerHandler { Schedulers.trampoline() }
}
}
