<@U7TJY2ZD3> Is <http://mockK.io|mockK.io> compatible w/ Android Espresso?

I haven't tested that, dont know about other users, so have no idea.

We are still using mockito, but adding a `TestAppModule` which provides your mocks should work just the same

```
@Module
class TestAppModule(private val application: Application) {

    @Singleton
    @Provides
    fun provideMockNavigationRouter(): NavigationRouter = mock()
...
}
```
```
        val component = DaggerEspressoTestComponent
                .builder()
                .testAppModule(TestAppModule(application))
                .build()

        Application.dependencies = component
```

<@U6X2VRZN1> You declare a `public var dependencies` in your Application's `companion object`? So the real dependencies get loaded and then you overwrite them w/ the test deps?

<@U7TJY2ZD3> It would have been nice to have something like <https://github.com/fabioCollini/DaggerMock> for mockK...

Or is it maybe compatible or easily adaptable to mockK?

Yea we have a `EspressoTestComponent` which extends the `ApplicationComponent` so that we can override what gets injected
```
@Singleton
@Component(modules = [TestAppModule::class])
interface EspressoTestComponent : ApplicationComponent {
```
```
@Singleton
@Component(modules = [AppModule::class])
interface ApplicationComponent {
```

we also created a custom rule for setting it up

that’s where that component snippet is stolen from :slightly_smiling_face:

<@U6X2VRZN1> Do you have a little gist with a complete setup? I'm still not clear on all the details... :thinking_face:

If I get a minute later I’ll strip out any copyrighted stuff and send you it
