PHPUnit Mocking View Helper ZF2

我创建了一个View Helper：

class SousMenuContrat extends AbstractHelper
{
    private $maiContratService;

    public function __construct(
        FMaiContratService $maiContratService,
    ) {
        $this->maiContratService                = $maiContratService;
    }

    public function __invoke($iMaiContratId, $sActive)
    {
        $oContrat = $this->maiContratService->selectById($iMaiContratId);

        return $this->getView()->partial('maintenance/sousmenucontrat', array(
            'oContrat'         => $oContrat
        ));
    }
}

所以现在我需要使用PHPUnit测试它：

class SousMenuContratTest extends TestCase
{
    private $myService;

    public function setUp()
    {
        $maiContratService = $this->getMockBuilder('Maintenance\Service\Model\FMaiContratService')
            ->disableOriginalConstructor()
            ->getMock();

        $oContrat = new FMaiContrat();
        $stub = $this->returnValue($oContrat);
        $maiContratService->expects($this->any())->method('selectById')->will($stub);
        $this->myService = new SousMenuContrat(
            $maiContratService
        );
    }

    public function testInvoque()
    {
        $this->myService->__invoke(2, 'contrat');
    }
}

但测试发送错误,因为测试不知道：

$this->getView()->partial();

提前致谢 ：)

解决方法:

在测试中,您需要模拟getView()返回的渲染器：

    /** @var PHPRenderer|\PHPUnit_Framework_MockObject_MockObject $rendererMock */
    $rendererMock = $this->getMockBuilder('Zend\View\Renderer\PHPRenderer')
        ->disableOriginalConstructor()
        ->getMock();
    $rendererMock->expects($this->once())
        ->method("partial")
        ->with(array(
            'maintenance/sousmenucontrat',
            array('oContrat' => new FMaiContrat()),
        ));
    $this->myService->setView($rendererMock);

最好的解决方案是使用你在with()中的setUp()中实例化的相同FMaiContrat对象,但在这种情况下,这也适用.

编辑：完整的测试代码如下所示：

class SousMenuContratTest extends TestCase
{
    private $myService;

    public function setUp()
    {
        $maiContratService = $this->getMockBuilder('Maintenance\Service\Model\FMaiContratService')
            ->disableOriginalConstructor()
            ->getMock();

        $oContrat = new FMaiContrat();
        $stub = $this->returnValue($oContrat);
        $maiContratService->expects($this->any())->method('selectById')->will($stub);
        $this->myService = new SousMenuContrat(
            $maiContratService
        );
    }

    public function testInvoque()
    {
        /** @var PHPRenderer|\PHPUnit_Framework_MockObject_MockObject $rendererMock */
        $rendererMock = $this->getMockBuilder('Zend\View\Renderer\PHPRenderer')
            ->disableOriginalConstructor()
            ->getMock();
        $rendererMock->expects($this->once())
            ->method("partial")
            ->with(array(
                'maintenance/sousmenucontrat',
                array('oContrat' => new FMaiContrat()),
            ));
        $this->myService->setView($rendererMock);
        $this->myService->__invoke(2, 'contrat');
    }
}
