Symfony 4：如何在KernelTestCase中加载DataFixtures

问题描述

我设置了DataFixtures，可以通过控制台将其加载到测试数据库中。

I got DataFixtures set up, that I can load via console into my test database.

$ php bin/console doctrine:fixtures:load --env=test -n
> purging database
> loading App\DataFixtures\PropertyFixtures
> loading App\DataFixtures\UserFixtures
> loading App\DataFixtures\UserPropertyFixtures

工作方式类似于chram

works like a chram

但是我不知道如何在服务单元测试中自动加载这些灯具，而不必在测试之前手动运行命令。

But I am lost how to load these fixtures automatically with my service unit tests, without having to run the command manually before testing. There has to be another way!

到目前为止，我发现的是使用较旧版本的symfony进行测试或对Controller进行测试的描述。

What I found so far is descriptions for testing with older versions of symfony or for testing Controllers. Who wants to test Controllers anyway, if you can avoid it?

Liip\FunctionalTestBundle似乎也只适用于WebTestCases，至少我没有办法扩展或替换通常的KernelTestCase。

The Liip\FunctionalTestBundle also seems to work only for WebTestCases at least I have seen no way to extend or replace the usual KernelTestCase.

那么我有什么方法可以通过测试类的setUp（）方法运行命令？

So is there any way I can maybe run the command with the setUp() method of my test class?

是否有指向symfony 4教程的链接？有服务示例吗？我无法想象，我是唯一遇到此问题的人。

Any link to a tutorial for symfony 4? Any example for a service? I cannot imagine, that I am the only person with that problem.

推荐答案

我有一个解决方案，尽管它并不完整这里是美丽和风格。我们会欣赏更优雅的替代方法。

I got a solution and although it is not full of beauty and style here it is. More elegant alternatives are appreciated.

我用一个名为AppKernel的类扩展了在Kernel.php中找到的Kernel类。
要激活它以进行测试，并且只有我更改了phpunit.xml文件，才能进行激活：

I extended my Kernel class found in Kernel.php with a class called AppKernel.To activate it for tests and only those I changed my phpunit.xml file:

<php>
    <ini name="error_reporting" value="-1" />
    <env name="KERNEL_CLASS" value="App\AppKernel" />

因此，现在仅对于此类加载的测试。

So now only for tests this class is loaded.

在AppKernel类中，我将启动方法扩展如下：

In the AppKernel Class I extended the boot method as follows:

public function boot()
{
    parent::boot();
    $this->importDataFixtures();
}

/**
 * Loads the tests data for DataFixtures when we start phpUnit.
 */
protected function importDataFixtures()
{
    system('php /var/www/octopus/bin/console doctrine:fixtures:load --env=test -n');
}

因此，通过系统导入的调用当然很丑陋，但它的工作原理。如果有人有更好的主意，请告诉我。

So of course the call of the import via system is ugly, but it works. If somebody has a better idea, please let my know.
