Symfony2：CRUD生成的功能测试失败

Question

在CRUD生成器生成的简单且略微修改的功能测试中，爬虫测试失败。这是通过检查在断言之前创建的外部文件中的内容来确定的。并通过页面的元素检查。并通过手动运行jquery代码$("td:contains('Test')").length;那么为什么测试失败？

测试类：

class ApplianceControllerTest extends WebTestCase {

    private $client;

    public function __construct() {
        $this->client = static::createClient(array(), array(
         ...
        ));
        $this->client->followRedirects();
    }

    public function testCompleteScenario() {
        // Create a new entry in the database
        $crawler = $this->client->request('GET', '/appliance/');
        $crawler = $this->client->click($crawler->selectLink('Create a new entry')->link());

        // Fill in the form and submit it
        $form = $crawler->selectButton('Create')->form(array(
            'appliance[appliance]' => 'Test',
                // ... other fields to fill
        ));

        $this->client->submit($form);
//        $crawler = $this->client->followRedirect();
        $content = $this->client->getResponse()->getContent();
        file_put_contents('somefile', $content);

        // Check data in the show view
        $this->assertGreaterThan(0, $crawler->filter('td:contains("Test")')->count(), 'Missing element td:contains("Test")');
}

输出：

  

缺少元素td：包含（＆＃34;测试＆＃34;）失败断言0更大   比0。

捕获内容的摘录：

<div class="title">Appliance</div>
<div class="width40">

    <table class="record_properties">
        <tbody>
            <tr>
                <th>Id</th>
                <td>14</td>
            </tr>
            <tr>
                <th>Appliance</th>
                <td>Test</td>
            </tr>
            <tr>
                <th>Enabled</th>
                <td>Yes</td>
            </tr>
        </tbody>
    </table>

总结评论主题：

由于错误“LogicException：请求未被重定向”，您已注释掉$crawler = $this->client->followRedirect();。此错误表示表单提交不成功。

正如您所发现的那样，从__construct（）中删除行$this->client->followRedirects();并恢复行$crawler = $this->client->followRedirect();会修复您的测试。
