Symfony WebTestCase：文件上载未删除，断言仍在传递

多亏了，我有一个文件上传表单，效果很好。但是它没有测试覆盖率，所以我写了自己的断言，上传一个图像，检查图像是否已上传，然后删除图像，检查图像是否未显示在页面上

它们都是第一次通过的，包括检查图像（或图像名称）是否不存在的最终断言，但它不会删除它，而且我仍然可以在网页上看到它。因此，在此之后运行的任何测试都将失败，因为爬虫程序会找到旧条目。为什么会这样

测试

public function testUploadScenario()
{
    // Upload image
    $crawler = $client->click($crawler->selectLink('Upload')->link());
    $this->assertEquals(1, $crawler->filter('html:contains("Upload file attachment")')->count());

    $pathToTestUploadFile = static::$kernel->getRootDir().'/../src/Acme/MyBundle/Resources/public/logo.gif';

    $uploadForm = $crawler->selectButton('Upload')->form();

    $uploadForm['upload[name]'] = "Logo Test";
    $uploadForm['upload[file]']->upload($pathToTestUploadFile);

    $crawler = $client->submit($uploadForm);

    // Check that the session flash message confirms the attachment was uploaded.
    $this->assertTrue($client->getResponse()->isSuccessful());
    $this->assertEquals(1, $crawler->filter('html:contains("File uploaded")')->count());

    // Delete the image
    $crawler = $client->submit($crawler->selectButton('Delete')->form());

    $this->assertEquals(0, $crawler->filter('html:contains("Logo Test")')->count());
    $this->assertEquals(1, $crawler->filter('html:contains("File has been deleted")')->count());
}

控制器

/**
 * Finds and displays an attachment.
 *
 * @param integer $id
 */
public function showAction($id)
{
    $em = $this->getDoctrine()->getManager();

    $attachment = $em->getRepository('AcmeMyBundle:Attachment')->find($id);

    if (!$attachment) {
        throw $this->createNotFoundException('Unable to find attachment file.');
    }

    return $this->render('AcmeMyBundle:Attachment:show.html.twig', array(
        'attachment'  => $attachment,
        'delete_form' => $this->createDeleteForm($id)->createView()
    ));
}

/**
 * Deletes an attachment file from the database.
 *
 * @param Request $request
 * @param integer $id
 *
 * @return Response
 */
public function deleteAction(Request $request, $id)
{
    $form = $this->createDeleteForm($id);
    $form->bind($request);

    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $attachment = $em->getRepository('AcmeMyBundle:Attachment')->find($id);

        if (!$attachment) {
            throw $this->createNotFoundException('Unable to find attachment file.');
        }

        $em->remove($attachment);
        $em->flush();
    }

    $this->getRequest()->getSession()->getFlashBag()->add('notice', 'File has been deleted.');

    return $this->redirect($this->generateUrl('attachment_index'));
}

/**
 * Creates a form to delete an attachment file by id.
 *
 * @param mixed $id The attachment id
 *
 * @return Symfony\Component\Form\Form The form
 */
private function createDeleteForm($id)
{
    return $this->createFormBuilder(array('id' => $id))->add('id', 'hidden')->getForm();
}

无论提交的表单是否有效，您都将添加flash通知

您正在检查是否存在“文件已被删除”。但通知不会添加到if语句中

 if ($form->isValid()) {
     // ...
     $this->getRequest()->getSession()->getFlashBag()->add('notice', 'File has been deleted.');
 }

您应该在try-catch块中进一步包装

$em->remove（$entity）

，因为如果您在pre/postRemove侦听器中删除该文件，该实体仍然可能有效，但由于权限问题导致异常，无法删除该文件。

干杯。不知道我怎么会错过那个。。。现在看起来很明显；）我肯定也会使用try-catch挡块。
