【中文标题】仅当访问 Laravel 5 中的根页面（ visit(\'/\') ）时，PHPUnit 测试才会失败【英文标题】：PHPUnit testing FAILS ONLY when visiting the root page( visit('/') ) in Laravel 5仅当访问 Laravel 5 中的根页面（ visit('/') ）时，PHPUnit 测试才会失败 【发布时间】：2016-10-28 20:21:30 【问题描述】：

我在 docker 容器 dockervel 中运行 Laravel 应用程序，并且

测试 

<?php
use Illuminate\Foundation\Testing\WithoutMiddleware ;
use Illuminate\Foundation\Testing\DatabaseMigrations ;
use Illuminate\Foundation\Testing\DatabaseTransactions ;
use App\User1;

class MyTest extends TestCase


    public function testExample()
    
        $this->assertTrue(true);
    
     public function providerAllUrisWithResponseCode()
    
        return [
            ['/', 200],
            ['/thank', 200],
            ['/non-existing', 404],
        ];
    
    public function testDisplayThankYou($value='')
    
        $this->visit('/thankyou')
        ->see('THank you!');

    

    public function testNewUserRegistration()
    
        $this->visit('/')
         ->type('Taylor', 'name')
         ->type('taylor@talor.com', 'email')         
         ->press('Register')
         ->seePageIs('/thankyou');
    

    public function testPageControllerGet()
    
        $this->call('GET', '/');
    

    public function testPageControllerGettoThankYou()
    
        $this->call('GET', 'thankyou');
    

    public function testUser1ControllerPost()
    
        $response= $this->call('POST', '/');

只有当 $this->visit('/') 显示方法 testNewUserRegistration 时它才会失败： 

There was 1 failure:

1) MyTest::testDisplayWelcome
A request to [http://localhost] failed. Received status code [500].

Caused by
exception 'PDOException' with message 'SQLSTATE[HY000] [2005] Unknown mysql server host 'mysql' (2)' in ..vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:55

注意：可以通过我的应用进入数据库。

laravel.log：

请帮忙！

【问题讨论】：

您收到的状态码为500。检查您的日志以查看引发了什么错误。 @z3r0ck 以上更新了一个日志文件。 'mysql' =&gt; [ 'driver' =&gt; 'mysql', 'host' =&gt; env('DB_HOST', 'mysql'), 尝试将 .env 中的 DB_HOST 值更改为 localhost。 @z3r0ck 同样的事情正在发生。 但是当我改变 我得到这个异常 'PDOException' 并带有消息 'SQLSTATE[HY000] [2002] Can't connect to local MySQL通过 /home/zagorka/Desktop/docker/dockervel/www/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php 中的套接字 '/var/run/mysqld/mysqld.sock' (2)' 服务器:55 【参考方案1】：

尝试其他版本要容易得多。它基于 PHP 7，可以在一个命令中运行 phpunit 测试dunit

$ dstop $ git checkout builder $ . ./aliases.sh $ dup $ dunit

【讨论】：

这对 PhpUnits 有帮助！谢谢！但我想知道为什么它失败了，因为我在运行 Behat 时在日志中得到了同样的错误，问题就在这里：***.com/questions/38109339/…【参考方案2】：

试试这个： 查看mysql 容器是否已启动：docker ps 您应该会看到一个 mysql 容器。如果没有，则运行dstop & dup

【讨论】：

【参考方案3】：

我认为您的代码 sn-p 中发生了两件事。

第一件事是您将 host 定义为mysql，而不是 driver（我认为这是您要设置的那个）。尝试将环境变量DB_CONNECTION 设置为mysql 而不是DB_HOST。

第二件事是你需要在你的测试类中添加DatabaseMigrations trait，尝试添加这个：

<?php

// Imports

class MyTest extends TestCase 

    use DatabaseMigrations; // This line
    ...

如果没有这个，你的测试可能会失败，因为它会找到数据库，但它不会找到在其中创建的任何表。

希望对你有帮助。

编辑

测试的最佳实践是模拟需要与数据库通信的依赖项，或者使用内存数据库进行测试，将它们与真实数据库分开。

为了将测试数据库与真实数据库分开，您可以在内存中使用sqlite 驱动程序。只需在 database.php 文件中更新您的 sqlite 驱动程序，如下所示：

'sqlite' => [
    'driver'   => 'sqlite',
    'database' => ':memory:',
    'prefix'   => '',
],

并在您的测试中将其用作DB_CONNECTION 环境变量（修改phpunit.xml）：

<env name="DB_CONNECTION" value="sqlite"/>

【讨论】：

嗯，当添加 DatabaseMigration 时，每个测试方法都会发送一个与上面相同的错误，因为即使其中一些不需要它，它也会尝试连接到数据库。 这里的最佳实践可能是模拟所有需要与数据库通信的控制器依赖项，或者使用sqlite 驱动程序和内存中的数据库，这样你就不需要不得不担心数据库访问。我用 sqlite 配置修改了我的答案。 sqlite 更改没有帮助，同样的问题。
