phpunit\framework\testcase未找到symfony 4

我正在尝试将窗体添加到控制器,但它只返回以下错误:

致命错误:在第21行的/var/www/site/vendor/symfony/form/test/formintegrationtestcase.php中找不到类“phpunit\framework\testcase”

不过,我不太清楚为什么。乍一看,似乎没有找到普普尼特,而是在跑。 cat composer.json 在我的目录里,不是这样说的:

所以我可以在那里看到…这是我的控制器:

<?php
    namespace App\Controller\Bug;

    use App\Entity\Bug;
    use App\Form\Bug\AddType;
    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
    use Symfony\Component\HttpFoundation\Request;

    class AddController extends Controller
    {
        public function add(Request $request, \Swift_Mailer $mailer)
        {
            # I know setting errors this way isn't best
            # but was faced with White Screen of Death
            ini_set('display_startup_errors', 1);
            ini_set('display_errors', 1);
            error_reporting(-1);

            $bug = new Bug();

            $form = $this->createForm(AddType::class, $bug);
            $form->handleRequest($request);

            $user = $this->getUser();

            if ($form->isSubmitted() && $form->isValid()) {
                $em = $this->getDoctrine()->getManager();

                $bug->setCreatedTs(new \DateTime());
                $bug->setSubmittedBy($user);
                $bug->setStatus('new');

                try {
                    $em->persist($bug);
                    $em->flush();

                    $this->addFlash('success', 'Bug Submitted.');

                    $message = (new \Swift_Message('Incoming Bug'))
                        ->setTo('t.taylor@sinnis.co.uk')
                        ->setBody(
                            $this->renderView(
                                'emails/bugs/add.html.twig',
                                array(
                                    'bug' => $bug,
                                    'submitted_by' => $user
                                )
                            ),
                            'text/html'
                        );

                    $mailer->send($message);
                } catch (\Exception $e) {
                    $this->addFlash('danger', 'Processing Error. Please try again.');
                }

                return $this->redirectToRoute('bug_add');
            }

            return $this->render('bug/add.html.twig', array('form' => $form->createView()));
        }
    }

我的FormType:

<?php
    namespace App\Form\Bug;

    use App\Entity\Bug;
    use Symfony\Component\Form\AbstractType;
    use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
    use Symfony\Component\Form\Extension\Core\Type\TextareaType;
    use Symfony\Component\Form\FormBuilderInterface;
    use Symfony\Component\Form\Tests\Extension\Core\Type\TextTypeTest;
    use Symfony\Component\OptionsResolver\OptionsResolver;

    class AddType extends AbstractType
    {
        public function buildForm(FormBuilderInterface $builder, array $options)
        {
            $builder->add('summary', TextTypeTest::class)
                ->add('description', TextareaType::class)
                ->add('priority', ChoiceType::class, array(
                    'choices' => array(
                        'Low' => 'low',
                        'Medium' => 'medium',
                        'High' => 'high',
                        'Site Breaking' => 'extreme'
                    )
                ))
                ->add('website', ChoiceType::class, array(
                    'choices' => array(
                        'Site One' => 'site-one',
                        'Site Two' => 'site-two',
                        'Site Three' => 'site-three'
                    )
                ));
        }

        public function configureOptions(OptionsResolver $resolver)
        {
            $resolver->setDefaults(array());
        }
    }

我的twig文件只是表单的基本实现:

{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}

我不知道为什么会发生这个错误,也不知道如何阻止它?我不想跟普普尼特过不去,但它却在这里抬起它丑陋的头。
