Espresso - click on the button of the dialog

I want to test the permissions of Android 6, but I didn't find the way to click on the "Allow" button using Espresso. Is there a way to do this?

enter image description here

The version of Espresso is 2.2.1.

The test:

@Test
public void acceptFirstPermission() throws Exception {
onView(withText("ALLOW")).perform(click());
}


Behaviour:


I still receiving the frozen screen with the Dialog (like on the screenshot). Test executing all time until he becomes finished.


Output:

Running tests
Test running started
android.support.test.espresso.NoActivityResumedException: No activities in stage RESUMED. Did you forget to launch the activity. (test.getActivity() or similar)?

Answer

I see that you're trying to test app permission. I think it might be pretty impossible to test it with Espresso. You may need to take this action another UI testing tool called uiatomator.

uiatomator, another great tools made by Google allows you to test your Android system functions like notifications and screen lock. You can use it with Espresso test framework.

For finding more info, please read this article:

and uiautomator documentation, which you would find here.
