Android Robolectric unit test for Marshmallow PermissionHelper -

i wanna learn robolectric use unit tests on android marshmallow app. wrote permissionhelper methods make permission handling bit easier. started unit tests class, trying test simple method:

public static boolean haspermissions(activity activity, string[] permissions) {     (string permission : permissions) {         int status = activitycompat.checkselfpermission(activity, permission);         if (status == packagemanager.permission_denied) {             return false;         }     }     return true; } 

here robolectric test wrote far:

@runwith(robolectrictestrunner.class) @config(constants = buildconfig.class) public class permissionhelpertest {      private permissionhelper permissionhelper;     private shadowapplication application;      @before     public void setup() {         pictureactivity activity = robolectric.buildactivity(pictureactivity.class).get();         permissionhelper = new permissionhelper(activity, activity, 1);         application = new shadowapplication();     }      @test     public void testhaspermission() throws exception {         string[] permissions = new string[]{manifest.permission.record_audio, manifest.permission.write_external_storage};         boolean haspermissions = permissionhelper.haspermissions(permissions);         assert.assertequals(false, haspermissions);          application.grantpermissions(permissions);         haspermissions = permissionhelper.haspermissions(permissions);         assert.assertequals(true, haspermissions);     } } 

the first assert works (no permission granted). after granting permissions via shadowapplication still denied in next assert.

i think pictureactivity created robolectric.buildactivity() not using shadowapplication permission checks. pictureactivity.getapplication() not give me shadowapplication call grantpermissions on. how can test this?

i new robolectric , unit testing on android...so if there other framework makes easier/possible: open suggestions.

your problem you're using different application grant permissions, not own.

instead of this:

application = new shadowapplication(); 

you should shadow of your application, this:

application = shadows.shadowof(activity.getapplication());
