How can we access context of an application in Robolectric?

Update.

Just use for version 1.x and 2.x:

Robolectric.application;

And for version 3.x:

RuntimeEnvironment.application;

And for version 4.x:

• add to your build.gradle file:

  testImplementation 'androidx.test:core:1.0.0'
  

• retrieve the context with:

  ApplicationProvider.getApplicationContext()
