I would like to check the array given to a view in a controller function has certain key value pairs. 
//my controller I am testing
public function getEdit ($user_id)
{
    $this->data['user'] = $user = \Models\User::find($user_id);
    $this->data['page_title'] = "Users | Edit";
    $this->data['clients'] = $user->account()->firstOrFail()->clients()->lists('name', 'id');
    $this->layout->with($this->data);
    $this->layout->content = \View::make('user/edit', $this->data);
}
//my test
public function testPostEdit (){
    $user = Models\User::find(parent::ACCOUNT_1_USER_1);
    $this->be($user);
    $response = $this->call('GET', 'user/edit/'.parent::ACCOUNT_1_USER_1);   
    //clients is an array.  I want to get this 
    //array and use $this->assetArrayContains() or something
    $this->assertViewHas('clients');
    $this->assertViewHas('content');
}
How do I do this using phpunit testing?
