MockitoJUnitRunner for junit in AemContext how to set user details

Hi ,

I am using MockitoJUnitRunner for Junit .

I having the below code in java :-

User currentUser = request.getResourceResolver().adaptTo(User.class);

if(currentUser.isAdmin())
return;

Iterator<Group> currentUserGroups = currentUser.memberOf();

while (currentUserGroups.hasNext()) {
Group grp = (Group) currentUserGroups.next();
if(grp.getID().equals(GROUP)) {
-----
}
}

issue:-

So want to simulate the user and groups using Aemcontext and want to know how to set up user and group details for AEM context

I am using the below code 

@RunWith(MockitoJUnitRunner.class)
public class ComponentTestingTest {

    @Rule
    public final AemContext context = new AemContext(ResourceResolverType.JCR_MOCK);
}



Thanks
