I have been trying to run Robolectric along with Espresso but, I haven’t been successful yet. After trying to figure out what was causing this, I realized my FragmentContainerView in my activity is causing this and I am not sure how to fix it.
I decided to create a blank project thinking that perhaps something in my project was causing this, and I encountered the same issue on the blank project.
This is the current setup where I am testing this.
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

So, I tried using the suggestion in the exception:

}
}
But I encountered the same exception:

Any help is greatly appreciated!

Answer
I figured out the issue. What was causing this to not work correctly was the following dependency for navigation component.
// Jetpack Compose Integration implementation "androidx.navigation:navigation-compose:2.4.0-alpha01"
After I removed it, it not only fixed my issue with robolectric and espresso but, also another one with navigation testing. I am not sure what happened in the latest version but, since I updated that specific dependency, it doesn’t seem to be compatible with both robolectric and navigation testing.
