错误：“在KERNEL_DIR中设置phpunit.xml”，但KERNEL_DIR在phpunit.xml.dist中被设置为"<server name="KERNEL_DIR“value=”/“>”

Question

在尝试PHPUnit功能测试时，我得到了错误：

1) TreningBundle\Tests\Controller\DefaultControllerTest::testIndex
RuntimeException: Either set KERNEL_DIR in your phpunit.xml according to https://symfony.com/doc/current/book/testing.html#your-first-functional-test or override the WebTestCase::createKernel() method.

http://symfony.com/doc/2.8/book/testing.html说：

如果内核位于非标准目录中，则需要修改phpunit.xml.dist。

我在phpunit.xml.dist目录中的聋Symfony (2.8) place中找到了文件app\和AppKErnel.php。无论如何，我在app/phpunit.xml.dist中添加了下面一行

<php>
     <server name="KERNEL_DIR" value="./" />
</php>

结果相同的错误。

绝对路径：

<server name="KERNEL_DIR" value="C:\wamp\www\treningPHPUnitSymfony2.8\app" />

同样的错误。

Answer 1

使用Symfony 2.8.17，我们的内核在/app和phpunit.xml.dist中处于相同的级别。所以我们加了；

<php>
    ....
    <server name="KERNEL_DIR" value="app" />
</php>

PS:额外信息；由于我们的设置，我们还需要使用putenv("X_ENV=test")获得配置细节，以完成测试。
