FAILURES!
Tests: 1, Assertions: 0, Errors: 1.

非常感谢任何人都可以提供的任何见解！！！谢谢

更新：这是测试代码：

namespace Tests\AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class DefaultControllerTest extends WebTestCase
{
    public function testIndex()
    {
        $client = static::createClient();

        $crawler = $client->request('GET', '/');

        $this->assertEquals(200, $client->getResponse()->getStatusCode());
        $this->assertContains('TEST TEXT', $crawler->filter('#homepage .jumbotron')->text());
    }
}

更新：这是我的 phpunit.xml.dist

<?xml version="1.0" encoding="UTF-8"?>

<!-- https://phpunit.de/manual/current/en/appendixes.configuration.html -->
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </exclude>
        </whitelist>
    </filter>
</phpunit>

这是我的 autoload.php

<?php

use Doctrine\Common\Annotations\AnnotationRegistry;
use Composer\Autoload\ClassLoader;

/** @var ClassLoader $loader */
$loader = require __DIR__.'/../vendor/autoload.php';

AnnotationRegistry::registerLoader([$loader, 'loadClass']);

return $loader;

这里是 vendor/autoload.php

<?php

// autoload.php @generated by Composer

require_once __DIR__ . '/composer' . '/autoload_real.php';

return ComposerAutoloaderInit2554ac6f5d571f82debebd2d3d7133d2::getLoader();

附上 cli / phpinfo 模块的截图。

【问题讨论】：

  • 您可能应该在包含testIndex 的文件中显示代码。
  • 谢谢@AlvinBunk。好点子。我已经为单元测试添加了代码。
  • 该代码看起来不错。你是如何运行你的测试的？您能否显示您运行的确切 phpunit 命令以及从哪个路径运行，请更新您的帖子以显示此内容。
  • 再次感谢@AlvinBunk 的回复-您的问题让我对要检查的事情有了想法。我在 public_html 文件夹中，我运行了 phpunit tests/AppBundle/Controller/ 这次我注意到一条消息，上面写着“从 /var/www/sitename.com/public_html/phpunit.xml.dist 读取的配置”我已经编辑包含该文件的原始问题。我去看看是否需要将数据库连接信息添加到该配置文件中。
  • 您是否从您的 Symfony 根文件夹（即 /var/www/sitename.com/public_html）运行命令 phpunit？仅此而已，只需phpunit。

【解决方案1】：

正如日志所说，它正在尝试使用PDO_MYSQL 驱动程序连接到数据库。如果网站在通过 Apache/mod_php 或 PHP-FPM 运行时可以工作，那么您的配置在运行网站的 PHP 版本和用于运行 PHPUnit 的 CLI sapi 之间是不同的。比较 phpinfo() 和 php -m 中显示的 PHP 模块列表，这将显示可用于命令行“cli”服务器 API 的模块。

【讨论】：

  • 感谢@AlisterBulman 的回复。我觉得你是对的！我在那个 -m 列表中看到了 PDO，并认为这就是我所需要的。你能看看这个吗？你知道我需要在 Ubuntu 中安装什么才能让 pdo_mysql 工作吗？ （附截图）
  • 您已经安装了 pdo_mysql，但只在网络服务器中启用。您还需要在 CLI 中启用。 phpenmod -s cli pdo_mysql 可能就足够了。检查php -m | grep pdo_mysql。
  • 哇哦！ @AlisterBulman 你成功了。我已经安装了 PHP5，但是当我安装了 phpunit 时，PHP7 也被安装了...... php7 没有安装模块，而 PHP5 安装了。更新符号链接以指向 php5 现在允许单元测试运行！！！我想让 PHP7 工作，但我得到“警告：模块 pdo_mysql ini 文件在 /etc/php/7.1/mods-available 下不存在”......你介意让我知道你是否知道一种方法解决这个问题？是不是像在php/5/mods-available下找到一个ini文件，移动到php/7.1/mods-available一样简单？
  • @AlisterBulman - 我使用的是 Ubuntu，但它无法识别 phpenmod。 Ubuntu 有 php5enmod 命令。我执行了'php5enmod -s cli pdo_mysql'。没有得到回应。当我执行php -m时，它仍然没有php_mysql。
  • @user2305673 - 你好。除了我没有使用任何框架外，我对 phpunit 也有类似的问题。目前，我使用的是 PHP 7.0.10 Ubuntu 14.04、MySQL 5.5.49。我正在使用亚马逊的 Cloud9。我无法在 CLI 上安装 PDO_mysql。如果您能列出安装 PDO_mysql 的每个步骤，我将不胜感激。谢谢。
