PhpUnit failing in PhpStorm w/ exit code 255 in Symfony 2 project

Question

I'm having trouble getting phpunit working inside of a Symfony project in PhpStorm - phpunit -c app works fine in the OSX terminal.

Here is the error:

Unable to attach test reporter to test framework of test framework quit unexpectedly
/Applications/MAMP/bin/php/php5.4.4/bin/php/private/var/folders/4l/hw8g4qlj6nnc37lfkc6hcj7w0000gn/T/ide-phpunit.php --bootstrap
/Users/greg/Repos/MyApp/app/bootstrap.php.cache --configuration    
/Users/greg/Repos/MyApp/app/phpunit.xml.dist
MyApp\MyBundle\Tests\Controller\MyControllerTest 
/Users/greg/Repos/MyApp/src/HvH/MyBundle/Tests/Controller/MyControllerTest.php

Testing started at 11:45 AM ...

Process finished with exit code 255

Edit: Here is the error from the PHP log:

Fatal error: Uncaught exception 'InvalidArgumentException' with message 'The "app/" directory does not exist.' in /Users/greg/Repos/MyApp/vendor/symfony/symfony/src/Symfony/Component/Finder/Finder.php:650

Answer 1

I ran into the same issue and found the following solution in the documentation: http://symfony.com/doc/current/book/testing.html#your-first-functional-test

To run your functional tests, the WebTestCase class bootstraps the kernel of your application. In most cases, this happens automatically. However, if your kernel is in a non-standard directory, you'll need to modify your phpunit.xml.dist file to set the KERNEL_DIR environment variable to the directory of your kernel:

<phpunit>
    <!-- ... -->
    <php>
        <server name="KERNEL_DIR" value="/path/to/your/app/" />
    </php>
    <!-- ... -->
</phpunit>

So check your phpunit.xml.dist configuration file and try to add the absolute path to your app-directory.

Hope it helps.

PhpStorm does not always instantiate the test runner from the project root, to fix this add the absolute path to the project root under 'custom working directory' in the run/debug config. This will save you having to add the absolute path to the app in the phpunit.xml.dist config, it will also ensure that any relative path file includes (such as JSON test data) can be found.
