php - Symfony 功能测试失败，但相同的请求在浏览器中有效

Question

我关注了 Symfony documentation关于功能测试以便编写我的第一个，但我有一些问题。我通过浏览器获得的响应效果很好:

但是当我在 shell 中运行 phpunit -c app/ 时，我失败了。

1) AppBundle\Tests\Controller\MeterAPIControllerTest::testGetAllVariables Failed asserting that 500 matches expected 200.

这是代码:

<?php

namespace AppBundle\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MeterAPIControllerTest extends WebTestCase
{
    public function testGetAllVariables()
    {
        $client = static::createClient();
        $crawler = $client->request(
            'GET',
            '/meters/121/120/variables'
        );

        // Assert a specific 200 status code
        $this->assertEquals(200, $client->getResponse()->getStatusCode()); 
    }
}

如果我尝试另一个测试断言，我也会失败。

// Assert that the "Content-Type" header is "application/json"
$this->assertTrue(
    $client->getResponse()->headers->contains(
        'Content-Type',
        'application/json'
    )
);

编辑

当我在 app/logs/test.log 中运行 phpunit 时，我得到一个 PHP 异常:

[2016-03-31 15:25:21] request.CRITICAL: Uncaught PHP Exception Doctrine\Common\Persistence\Mapping\MappingException: "Invalid mapping file 'AppBundle.Entity.EM2Meter.orm.yml' for class 'AppBundle\Entity\EM2Meter'." at /Applications/MAMP/htdocs/iso50k1_tst_symfony/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php line 86 {"exception":"[object] (Doctrine\Common\Persistence\Mapping\MappingException(code: 0): Invalid mapping file 'AppBundle.Entity.EM2Meter.orm.yml' for class 'AppBundle\Entity\EM2Meter'. at /Applications/MAMP/htdocs/iso50k1_tst_symfony/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/MappingException.php:86)"} []

我该如何解决这个问题？

Answer 1

你没有告诉 symfony 客户端在端口 8000 上联系本地主机服务器，它仍然默认为 80。

当您实例化您的客户端时，像这样指定主机。

$client = static::createClient([], [
    'HTTP_HOST' => 'localhost:8000',
] );
