Testing Eloquent Save method from a repository - unit-testing

Question

Given an eloquent repo that looks something like that.
class PinRepo {
protected $pinModel;
public function __construct( Model $pinModel )
{
$this->pinModel = $pinModel;
}
public function addPinToProject( $page_id, $inputs )
{
$pin = new $this->pinModel();
$pin->fill($inputs);
$pin->save();
return $pin;
}
}
My first attempt was:
class PinRepoTest extends TestCase {
public function setUp()
{
parent::setUp();
$this->modelMock = Mockery::mock( 'Pin' );
$this->pinRepo = PinRepo( $this->modelMock );
}
public function testAddPinToPage()
{
$this->modelMock
->shouldReceive('fill')->with(["project_page_id"=>1])
->once()
->andReturn(Mockery::self())
->shouldReceive('save')
->once();
$this->pinRepo->addPinToProject( 2, ["project_page_id"=>1]);
}
}
But i get this error (Which kind of make sense)
"Method ::fill() does not exist on this mock object"
Given this setup, is there any way to get that test to pass ?

Answer 1

Here is what i came up with:
class modelStub extends Illuminate\Database\Eloquent\Model {
static $methodCalls = [];
public function fill(array $attributes)
{
self::$methodCalls['fill'] = TRUE;
return $this;
}
public function save(array $options = array())
{
self::$methodCalls['save'] = TRUE;
//dd($this);
return $this;
}
public function __set($name, $value)
{
//dd($name, $value);
static::$$name = $value;
return $this;
}
}
class pageModelStub extends modelStub {
static $project_guid = false;
}
public function testAddPageToProject()
{
$modelStub = new pageModelStub;
$this->pageRepo = new \Nota\Repos\PageRepo( $modelStub );
$this->pageRepo->addPageToProject('project_guid', ['fds']);
$this->assertTrue( $modelStub::$methodCalls['fill'] );
$this->assertTrue( $modelStub::$methodCalls['save'] );
$this->assertEquals( $modelStub::$project_guid, "project_guid" );
}
It seems hacky but at least I can test what matter to me on that method. Any improvements on this are very welcome.
