PhpUnit窗体不提交，没有错误

Question

我正在PhpUnit中进行功能测试，以测试只有一个字段和两个按钮的简单模式窗口功能（我尝试过各种方法，因此代码可能不干净，米粘贴只是为了显示的想法）：

$form = $crawler 
     // find all buttons with the text "Pridėti" 
     ->filter('button:contains("Pridėti")') 
     ->eq(0) 
     ->form()// select the first button in the list 
    ; 

    $form['appbundle_classinfo[name]'] = '5a'; 
    $crawler = $client->submit($form); 

    //It doesn't even save to database 
    $container = self::$kernel->getContainer(); 
    $em = $container->get('doctrine')->getManager(); 
    $classinfo = $em->getRepository('AppBundle:ClassInfo'); 

    //Echoes modal window 
    echo $client->getResponse()->getContent() ;die; 

我也试图的var_dump形式，它示出了值被添加到形式： 串（25）“appbundle_classinfo [名称]” [“值” ：protected] => string（2）“5a”

所以表单没有提交。你能帮我找出原因吗？

<?php 

namespace AppBundle\Tests\Controller; 

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase; 

class PostTest extends WebTestCase 
{ 
    public function testShowPost() 
    { 
     //returns a Client, your browser use your web site 
     $client = static::createClient(); 

     // The request() method (read more about the request method) returns a Crawler object which can be used to select elements in the response, click on links and submit forms. 
     $crawler = $client->request('GET', '/your/route/controller/action'); 

     // select button by name or id 
     $form = $crawler->selectButton('Login')->submit(); 

     //submit the form 
     $crawler->submit($form); 

     $this->assertGreaterThan(
      0, 
      $crawler->filter('html:contains("hello world")')->count() 
     ); 

     // get HTML content returned 
     dump($client->getResponse()->getContent()); 

    }
