laravel unit test index function in controlller

this is my index function

public function index($alias, $profileId)
{
    $this->setClientAndClientProfile($alias, $profileId);

    $routeData = Routedata
                        ::where('client_id', $this->client->id)
                        ->paginate(10);

    return view('client.route_data.index', compact('routedata'))->with('client', $this->client)->with('clientProfile', $this->clientProfile);
}

setClientAndClientProfile is function just to check type of user and bring his profile

so how to write a test for this function?
