Android Marshmallow: Test permissions with Espresso?

Question

The new permissions scheme introduced by Android Marshmallow requires checking for specific permissions at runtime, which implies the need to provide different flows dependi

Answer 1

You can grant permissions before the test is run with something like:

@Before
public void grantPhonePermission() {
    // In M+, trying to call a number will trigger a runtime dialog. Make sure
    // the permission is granted before running this test.
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        getInstrumentation().getUiAutomation().executeShellCommand(
                "pm grant " + getTargetContext().getPackageName()
                        + " android.permission.CALL_PHONE");
    }
}

But you can't revoke. If you try pm reset-permissions or pm revoke... the process is killed.
