錯誤：「在您的phpunit.xml中設置KERNEL_DIR」但KERNEL_DIR在phpunit.xml.dist中設置爲「<server name =」KERNEL_DIR「value =」./「>」

Question

while trynig to PHPUnit functional test I got error ：

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說：

if your kernel is in a non-standard directory, you'll need to modify your phpunit.xml.dist

我有文件deafult的Symfony（2.8）的地方phpunit.xml.dist和AppKErnel.php，裏面app\目錄。無論如何，我下面加線app/phpunit.xml.dist：

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

與結果同樣的錯誤。

以絕對路徑：

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

同樣的錯誤。

Answer 1

使用Symfony 2.8.17我們的內核在/app和phpunit.xml.dist處於同一級別。 所以我們增加了;

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

PS：Extra info; 由於我們的設置，我們還需要使用putenv("X_ENV=test")來獲取配置詳細信息以完成測試。
