Example code doesn't work

[aydot]

public function setUp()
{
    $this->FeedFactory = new \App\Test\Factory\PostFactory();
}

public function testSomething()
{
    $post = $this->FeedFactory(1); // create a single record
    $this->assertTrue(isset($post->id));

    $this->FeedFactory(10); // create 10 records
}

fails with PHP Fatal error: Call to undefined method...

However, if I assign the "class variable" into a local variable like so:

public function testSomething()
{
    $post = $this->FeedFactory; // create a single record
    $post(1); 
    $this->assertTrue(isset($post->id));

    $post(10); // create 10 records
}

it works

do you plan on implementing relationships?

public $user_id = 'factory|App\Model\Entity\User';
