Why can't I import AndroidJUnit4 and ActivityTestRule into my unit test class?

Question

I\'m having trouble importing some of the Android UI testing framework classes - I just can\'t figure out what is going wrong!

This is my class:

@Run         


        

Answer 1

From androidX use

androidTestImplementation 'androidx.test:rules:1.1.1'

androidTestImplementation 'androidx.test:runner:1.1.1'

In your dependencies section in your app level build.gradle file

for eg :

 dependencies {

     androidTestImplementation 'androidx.test:rules:1.1.1'
     androidTestImplementation 'androidx.test:runner:1.1.1'
 }

Then import

import androidx.test.rule.ActivityTestRule;

Answer 2

If you migrated to AndroidX, use this:

androidTestImplementation 'androidx.test:rules:1.1.1'
androidTestImplementation 'androidx.test:runner:1.1.1'
