Androidx.test.InstrumentationRegistry Is Deprecated

Answer :

You can use InstrumentationRegistry.getInstrumentation().getTargetContext() in the most cases from androidx.test.platform.app.InstrumentationRegistry.

If you need the Application, you can use ApplicationProvider.getApplicationContext<MyAppClass>().

If you haven't already, I think you can also use the new test dependency: androidTestImplementation 'androidx.test:core:1.0.0-beta02'.

When you're using Android X you need to make sure you have the following in your app's build.gradle file

androidTestImplementation 'androidx.test:core:1.1.0' androidTestImplementation 'androidx.test.ext:junit:1.1.0' 

The second one is to make sure you have the correct AndroidJUnit4 to use in your tests.

Make sure you import both of these.

import androidx.test.platform.app.InstrumentationRegistry import androidx.test.ext.junit.runners.AndroidJUnit4 

Now instead of using val context = InstrumentationRegistry.getContext() you can use the line shown below

val context = InstrumentationRegistry.getInstrumentation().getTargetContext() 

The following code is deprecated now:

Context context = InstrumentationRegistry.getInstrumentation().getTargetContext(); 

Instead use:

Context context = ApplicationProvider.getApplicationContext();
