Pphunit 不断给出错误：[1049] 未知数据库 ':memory:'

Question

我刚刚开始在 Laravel 7 中使用 phpunit。我遇到了一个无法找到解决方案的问题。我正在使用 Laravel 7 和 Xampp。

My phpunit.xml:

    <?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="./vendor/phpunit/phpcd ..
         cdit/phpunit.xsd"
         bootstrap="vendor/autoload.php"
         colors="true"
>
    <testsuites>
        <testsuite name="Unit">
            <directory suffix="Test.php">./tests/Unit</directory>
        </testsuite>
        <testsuite name="Feature">
            <directory suffix="Test.php">./tests/Feature</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./app</directory>
        </whitelist>
    </filter>
    <php>
        <server name="APP_ENV" value="testing"/>
        <server name="BCRYPT_ROUNDS" value="4"/>
        <server name="CACHE_DRIVER" value="array"/>
        <server name="DB_CONNECTION" value="mysql"/>
        <server name="DB_DATABASE" value=":memory:"/>
        <server name="MAIL_MAILER" value="array"/>
        <server name="QUEUE_CONNECTION" value="sync"/>
        <server name="SESSION_DRIVER" value="array"/>
        <server name="TELESCOPE_ENABLED" value="false"/>
    </php>
</phpunit>

我的测试功能：

<?php

namespace Tests\Feature;


use Illuminate\Foundation\Testing\DatabaseMigrations;


use Tests\TestCase;

class ThreadsTest extends TestCase
{

    use DatabaseMigrations;

    public function test_a_user_can_browse_threads()
    {
        $response = $this->get('/threads');

        $response->assertStatus(200);
    }
}

当我运行 phpunit (vendor/phpunit/phpunit/phpunit) 时，我得到以下信息：

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

.E                                                                  2 / 2 (100%)

Time: 1.57 seconds, Memory: 20.00 MB

There was 1 error:

ERRORS!
Tests: 2, Assertions: 1, Errors: 1.

而且我的MYSQL数据库中的表都被删除了。

有什么建议么？

亲切的问候，

休伯特

Answer 1

我猜你想sqlite作为内存数据库运行，至少这是我首选的测试设置。

为了实现这一点，你必须像这样在测试中设置你的环境。现在您已连接为Mysql，这不能使用内存设置为sqlite。

<server name="DB_CONNECTION" value="sqlite"/>
<server name="DB_DATABASE" value=":memory:"/>
