Why does PHPunit request KERNEL_DIR using Silex?

Question

I am trying to configure unit tests for my Silex application, but I keep getting this error message:

RuntimeException: either set KERNEL_DIR in your phpunit.xml according to http://symfony.com/doc/current/book/testing.html#your-first-functional-test , or override the WebTestCase :: createKernel () method.

This is my ./app/phpunit.xml.dist :

 <?xml version="1.0" encoding="UTF-8"?> <!-- http://www.phpunit.de/manual/current/en/appendixes.configuration.html --> <phpunit backupGlobals="false" backupStaticAttributes="false" colors="true" convertErrorsToExceptions="true" convertNoticesToExceptions="true" convertWarningsToExceptions="true" processIsolation="false" stopOnFailure="false" syntaxCheck="false" bootstrap="phpunit_bootstrap.php" > <testsuites> <testsuite name="Project Test Suite"> <directory>../src/Acme/*/Tests</directory> </testsuite> </testsuites> <!--<php>--> <!--<server name="KERNEL_DIR" value="/var/www/acme/api/app/" />--> <!--</php>--> </phpunit> 

This is my ./app/phpunit_bootstrap.php (including composer autoloader):

 <?php if ( !@include __DIR__ . '/../../vendor/autoload.php') { die(<<<'EOT' You must set up the project dependencies, run the following commands: wget http://getcomposer.org/composer.phar php composer.phar install EOT ); } 

My directory structure is this:

It looks like phpunit looking for *Kernel.php , but I don't know why.

Here is my unit test:

 <?php namespace Acme\User\Tests\Controller; use Symfony\Bundle\FrameworkBundle\Test\WebTestCase; class UserControllerTest extends WebTestCase { protected $headers; protected function setUp() { $this->headers = array( 'CONTENT_TYPE' => 'application/json', ); } public function testAuthUser() { $client = static::createClient(); $client->request('POST', ...); // Check the response content type $this->assertTrue( $client->getResponse()->headers->contains( 'Content-Type', 'application/json' ) ); // Assert that the response status code is 2xx $this->assertTrue($client->getResponse()->isSuccessful()); $response = json_decode($client->getResponse()->getContent(), true); var_dump($response);die; } }

Good,

I managed to get it to work. I had a few setup issues.

First in my app/phpunit_boostrap.php , I added:

 <?php $_SERVER['env'] = 'test'; ... 

Then in my web/index.php I added:

 // Return the kernel instead to run it if we are unit testing if ('test' == $app['mode']) { return $app; } $app->run(); 

Then in my app/application.php I added:

 ... // Set dev mode for unit testing if (isset($_SERVER['env']) && 'test' === $_SERVER['env']) { $app['mode'] = 'test'; } ... 

I noticed that I did not use the correct WebTestCase , Silex has its own where you need to create the application (install the kernel):

 <?php namespace Acme\User\Tests\Controller; // Notice the Silex class for the WebTestCase use Silex\WebTestCase; class UserControllerTest extends WebTestCase { protected $headers; public function createApplication() { // index.php should return the $app instead to run() it return require __DIR__ . '/../../../../../web/index.php'; } protected function setUp() { // Don't forget to call the parent setup that is setting the kernel parent::setUp(); $this->headers = array( 'CONTENT_TYPE' => 'application/json', ); } public function testAuthUser() { // Create a client this way $client = $this->createClient(); $client->request('POST', ...); 

Now all is well. I also created my own WebTestCase class that extends one of Silex , so I don’t have to constantly install the application.

Hope this helps some of you as I did not find any good help in testing modules with Silex.
