Espresso ActivityTestRule For Activity With Generic Type Parameter

I have declared an activity like this class QuestionnaireActivity : AppCompatActivity() I want to write an espresso test so I'm writting ActivityTestRule l

Solution 1:

similar to here the solution involves defining an inline function like this

inline fun <reified T: Activity> activityTestRuleWithIntent(intent: Intent) =  object : ActivityTestRule<T>(T::class.java){
    override fun getActivityIntent(): Intent = intent
}

then the rule becomes:

@Rule @JvmField
val rule = activityTestRuleWithIntent<QuestionnaireActivity<ProfileModel.LifeStyleInfo>>(QuestionnaireActivity.getQuestionnaireIntent(InstrumentationRegistry.getTargetContext(), 3, ProfileModel.LifeStyleInfo()))
