Error on Instrumented Tests #18

Hi folks,

I cloned your repository and tried to run the Instrumented Test for the MainActivity (MainActivityTest), but it keeps raising the following error:

org.mockito.exceptions.base.MockitoException:

Is the error "right" or am I doing something wrong?

I also tried to copy the .MockMaker file to the androidTest directory, but it raises another error:

I have a project similar to yours, and I'm struggling almost a week to configure Mockito 2.x + Dagger 2 + Kotlin.
