AndroidJUnit4.class is deprecated: How to use androidx.test.ext.junit.runners.AndroidJUnit4?

Question

For my instrumentation tests I was using

@RunWith(AndroidJUnit4.class)

from

import androidx.test.runner.AndroidJUnit4;
         


        

Answer 1

According to the documentation for AndroidJUnit4,

1. The gradle file should contain the following line:

androidTestImplementation 'androidx.test.ext:junit:1.1.1'

2. Change test class to AndroidJUnit4ClassRunner from AndroidJUnit4

If it still doesn't work, make sure that you clean and/or rebuild your project. Also you can check the current version directly in Google's maven repository
