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 achieve this easily by granting permission before starting the test. For example if you are supposed to use camera during the test run, you can grant permission as follows

@Before
public void grantPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        getInstrumentation().getUiAutomation().executeShellCommand(
                "pm grant " + getTargetContext().getPackageName()
                        + " android.permission.CAMERA");
    }
}
