Unit testing Fungku's Hubspot API Library. Laravel 5

Goal: Use TDD to test code that works with Fungku's Hubspot Library (http://ift.tt/1wE432c) to submit subscription info to Hubspot.

Where: Running Laravel 5.1 inside vagrant VM on a Mac.

What: On a final checkout page, there is a subscribe checkbox. If that is checked we want the already entered and validated customer information to be sent to hubspot. I have setup a class that will be a middleman between Fungkus library and our code:

namespace app\Classes;

use App\Models\CountriesQuery;
use Fungku\HubSpot\HubSpotService;

class Hubspot
{
    private $hubspotOBJ;

    public function __construct() {
        $this->hubspotOBJ = HubSpotService::make();
    }

    public function subscribeCustomer($customerEmail, $customerArray)     {
        $result = $this->hubspotOBJ->contacts()->createOrUpdate($customerEmail, $customerArray);

        if($result->getStatusCode() == 200){
            return true;
        }
        return false;
    }
}

The arguments passed to the function look like:

$customerEmail = "test@test.com"

$customerArray = array(
    array('property' => 'email', 'value' => $customerEmail),
    array('property' => 'firstname', 'value' => "FirstName"),
    array('property' => 'lastname', 'value' => "LastName"),
    array('property' => 'phone', 'value' => "1234567890"),
    array('property' => 'mobilephone', 'value' => "9876543210"),
    array('property' => 'fax', 'value' => "1112223456"),
    array('property' => 'address', 'value' => "123 Some St."),
    array('property' => 'street_address_2', 'value' => "Apt. 4"),
    array('property' => 'state', 'value' => "IL"),
    array('property' => 'city', 'value' => "City"),
    array('property' => 'zip', 'value' => "12345"),
    array('property' => 'country', 'value' => "USA"),
    array('property' => 'lifecyclestage', 'value' => "customer"),
    array('property' => 'hs_persona', 'value' => "persona_3")
);

currently, I don't even have a full test written. This:

use Illuminate\Foundation\Testing\WithoutMiddleware;

class HubspotTest extends TestCase {
    use WithoutMiddleware;

    public function tearDown() {
        Mockery::close();
    }

    /**
     * @test
     */
    function it_subscribes_new_customer()
    {
        $mock = Mockery::mock('Fungku\HubSpot\HubSpotService');
    }
}

When I run phpunit, gives me this:

1) HubspotTest::it_subscribes_new_customer
ErrorException: Declaration of Mockery_0_Fungku_HubSpot_HubSpotService::__call() should be compatible with Fungku\HubSpot\HubSpotService::__call($name, $arguments = NULL)

/vagrant/REPO/vendor/mockery/mockery/library/Mockery/Loader/EvalLoader.php:34
/vagrant/REPO/vendor/mockery/mockery/library/Mockery/Container.php:231
/vagrant/REPO/vendor/mockery/mockery/library/Mockery.php:80
/vagrant/REPO/tests/HubspotTest.php:17

What is this error telling me?

As a side note. The code that sends information to hubspot is working fine. So I know everything other than the test is working as expected. Why am I getting the above error?

I know I need to mock Fungku's Library as I don't want to actually include the Hubspot API in the test. I'd like to be able to say that the call to

$this->hubspotOBJ->contacts()->createOrUpdate()

happens to say, I want to return that it was successful. Or maybe that it failed, and to test my code that handles that.

What am I missing? Any pointers or assistance would be gratefully appreciated!

Thanks
