PHPUnit and ZF2 Services - php

Question

I have a little problem when creating tests with PHPUnit.
Here is my setup :
protected function setUp()
{
$serviceManager = Bootstrap::getServiceManager();
$this->mockDriver = $this->getMock('Zend\Db\Adapter\Driver\DriverInterface');
$this->mockConnection = $this->getMock('Zend\Db\Adapter\Driver\ConnectionInterface');
$this->mockDriver->expects($this->any())->method('checkEnvironment')->will($this->returnValue(true));
$this->mockDriver->expects($this->any())->method('getConnection')->will($this->returnValue($this->mockConnection));
$this->mockPlatform = $this->getMock('Zend\Db\Adapter\Platform\PlatformInterface');
$this->mockStatement = $this->getMock('Zend\Db\Adapter\Driver\StatementInterface');
$this->mockDriver->expects($this->any())->method('createStatement')->will($this->returnValue($this->mockStatement));
$this->adapter = new Adapter($this->mockDriver, $this->mockPlatform);
$this->sql = new Sql($this->adapter);
$mockTableGateway = $this->getMock('Zend\Db\TableGateway\TableGateway', array(), array(), '', false);
$maiFormuleRevisionTable = $this->getMockBuilder('Maintenance\Model\BDD\PMaiFormulerevisionTable')
->setMethods(array())
->setConstructorArgs(array($mockTableGateway, $this->adapter, $this->sql))
->getMock();
$maiFormulerevisionService = $this->getMockBuilder('Maintenance\Service\Model\PMaiFormulerevisionService')
->setMethods(array())
->setConstructorArgs(array($maiFormuleRevisionTable))
->getMock();
$this->assertTrue($maiFormulerevisionService instanceof PMaiFormulerevisionService);
$this->controller = new RevisionsController($maiFormulerevisionService);
$this->request = new Request();
$this->routeMatch = new RouteMatch(array('controller' => 'index'));
$this->event = new MvcEvent();
$config = $serviceManager->get('Config');
$routerConfig = isset($config['router']) ? $config['router'] : array();
$router = HttpRouter::factory($routerConfig);
$this->event->setRouter($router);
$this->event->setRouteMatch($this->routeMatch);
$this->controller->setEvent($this->event);
$this->controller->setServiceLocator($serviceManager);
}
Here is the test for my function :
public function testEditFormuleActionCanBeAccessed()
{
$this->routeMatch->setParam('action', 'loadformule');
$this->routeMatch->setParam('idformule', '23');
$result = $this->controller->dispatch($this->request);
$response = $this->controller->getResponse();
$this->assertEquals(200, $response->getStatusCode());
}
And my Controler :
public function loadformuleAction()
{
try {
$iStatus = 0;
$iMaiFormuleRevisionId = (int) $this->params('idformule');
$oFormule = $this->maiFormulerevisionService->selectByIdOrCreate($iMaiFormuleRevisionId);
$maiFormulerevisionForm = new PMaiFormulerevisionForm($oFormule);
if ($this->getRequest()->isPost()) {
/* etc ... */
}
$viewModel = new ViewModel();
$viewModel->setTerminal(true);
$viewModel->setVariables([
'maiFormulerevisionForm' => $maiFormulerevisionForm,
'iMaiFormuleRevisionId' => $oFormule->getMaiFormuleRevisionId(),
'iStatus' => $iStatus
]);
return $viewModel;
} catch (\Exception $e) {
throw new \Exception($e);
}
}
But when I try to run my test, it shows an error, and I point that my test don't go into my service, when I call it ($this->maiFormulerevisionService) :
1) MaintenanceTest\Controller\RevisionsControllerTest::testEditFormuleActionCanBeAccessed
Exception: Argument 1 passed to Maintenance\Form\PMaiFormulerevisionForm::__construct() must be an instance of Maintenance\Model\PMaiFormulerevision, null given
I don't understand why my mock doesn't work ...
Thanks for your answers :)
Edit :
Hum ... when I try this :
$maiFormulerevisionService = new PMaiFormulerevisionService($maiFormuleRevisionTable);
Instead of this :
$maiFormulerevisionService = $this->getMockBuilder('Maintenance\Service\Model\PMaiFormulerevisionService')
->setMethods(array())
->setConstructorArgs(array($maiFormuleRevisionTable))
->getMock();
It goes into the service but not into the TableGateway specified in the constructor of the service ($maiFormuleRevisionTable) ... so it still doesn't work ...

Answer 1

You set a mock, but you also have to set what your mock returns when calling the method selectByIdOrCreate. Since you do:
$oFormule = $this->maiFormulerevisionService->selectByIdOrCreate($iMaiFormuleRevisionId);
$maiFormulerevisionForm = new PMaiFormulerevisionForm($oFormule);
The mock will return null for the selectByIdOrCreate method as long as you don't set a return value for this method.
Try to add a mock method like this:
$mock = $maiFormulerevisionService;
$methodName = 'selectByIdOrCreate';
$stub = $this->returnValue($maiFormuleRevisionTable);
$mock->expects($this->any())->method($methodName)->will($stub);
