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

1. Include these lines in build.gradle app module.

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

2. In the test class replace your test runner to

   import androidx.test.ext.junit.runners.AndroidJUnit4;

3. If InstrumentationRegistry.getTargetContext() is deprecated use InstrumentationRegistry from androidx.test.platform.app like this

   InstrumentationRegistry.getInstrumentation().getTargetContext()
