使用ZF2 Paginator进行phpUnit测试

Question

我正在编码phpUnit测试，但失败了：

Tests\Professor\Controller\DisciplinaControllerTest::testListaDisciplinas
Failed asserting response code "200", actual status code is "500"

为了在测试案例中出现问题时获得更多信息，我将受保护的$ traceError成员设置为true。 然后得到这个错误：

Tests\Professor\Controller\DisciplinaControllerTest::testListaDisciplinas
Argument 1 passed to Doctrine\ORM\Tools\Pagination\Paginator::cloneQuery() must be an instance of Doctrine\ORM\Query, array given, called in /uov-videos/www/david/plataovirtual/vendor/doctrine/orm/lib/Doctrine/ORM/Tools/Pagination/Paginator.php on line 239 and defined

发生这种情况是因为我的查询返回了一个Paginator对象，而我的测试需要一个数组 。 如何实例化模拟的Paginator以在测试中使用它？

phpUnit函数代码：

public function testListaDisciplinas()
{
    $this->auth();
    // simulate the repository to not affect the db
    $disciplinaRepository = $this->getMock('Domain\Model\Disciplina\DisciplinaRepository');

    $disciplinaRepository->method('getByProfessorTutor')
                         ->willReturn(array());

    $serviceManager = $this->getApplicationServiceLocator();
    $serviceManager->setAllowOverride(true);
    $serviceManager->setService('DisciplinaRepository', $disciplinaRepository);

    // Route to getList() above
    $result = $this->dispatch('/uov/professor/disciplinas');
    $this->assertResponseStatusCode(200);
}

在我的控制器内部：

public function getList()
{
    $usuario = $this->getSessaoUsuario();

    $professor = $this->professorRepository()->getByUsuario($usuario);

    $disciplinas = $this->disciplinaRepository()->getByProfessorTutor($professor);

    $adapter = new DoctrinePaginator($disciplinas);
    $paginator = new Paginator($adapter);
    $paginator->setDefaultItemCountPerPage(20);

    $view = new ViewModel(array(
        'disciplinas' => $paginator,
    ));

    $request = $this->getRequest();

    $view->setTerminal($request->isXmlHttpRequest());

    return $view;
}

我的存储库中的功能：

public function getByProfessorTutor(Professor $professor)
{
    $query = $this->em->createQueryBuilder();

    $query->select('d')
          ->from($this->class, 'd')
          ->leftJoin('Domain\Model\Turma\Turma', 't', 'WITH', 't.disciplina = d')
          ->leftJoin('Domain\Model\Professor\ProfessorTurma', 'pt', 'WITH', 'pt.turma = t.id')
          ->where('(t.professor = :professor OR pt.professor = :professor)')
          ->setParameter('professor', $professor);

    return new Paginator($query, $fetchJoinCollection = false);
}

我设法解决了这个问题。 这里是代码，如何模拟Doctrine Paginator对象。

public function testListaDisciplinas()
{
    $this->auth();
    // simulate the repository to not modify the db
    $disciplinaRepository = $this->getMock('Domain\Model\Disciplina\DisciplinaRepository');

    $em = $this->getApplicationServiceLocator()->get('Doctrine\ORM\EntityManager');

    $query = $em->createQueryBuilder();
    $query->select('d')
          ->from('Domain\Model\Disciplina\Disciplina', 'd')
          ->setMaxResults(1);

    $disciplinaRepository->method('getByProfessorTutor')
                         ->willReturn(new Paginator($query, $fetchJoinCollection = false));

    $serviceManager = $this->getApplicationServiceLocator();
    $serviceManager->setAllowOverride(true);
    $serviceManager->setService('DisciplinaRepository', $disciplinaRepository);
    $result = $this->dispatch('/uov/professor/disciplinas');
    $this->assertResponseStatusCode(200);
}
