Mockery testing constructor call, new keyword

Question

I have a class name as a string property. One method (fetchObject) creates new instance of this class. I would like to test this method with PHPUnit and Mockery.

That's the code

class Maker
{
    private $_className = 'Article';

    public function fetchObject( $array )
    {
        return new $this->_className( $array );
    }
}

I tried something like this

$data = array( 'title' => 'Amazing title' );
$article = m::mock( 'Article', array( $data ) );

$maker= new Maker;
$result = $maker->fetchObject( array() );

Test works but I'm not sure if it checks for constructor call and I don't know how to check if param was passed.

Answer 1

Normally you would mock the Maker() class, and ensure it returned from the mock, the object you are looking for.

The other option I have done to test things like this, is to simply test Maker and call the fetchObject() routine with a given class expectation, and then test with an InstanceOf check that the returned object is of the desired class.
