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

Posted by: admin July 12, 2020 Leave a comment


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    

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
How to&Answers:

I ran into the same issue and found the following solution in the documentation:

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:

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

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.


Steps to make it work (test in PHPStorm 8.0.1):

1) In Preferences > PHP > PHPUnit make sure that nothing is set for Default configuration file or default bootstrap file.

2) Make a custom PHPUnit Configuration via Run > Edit Configurations > in the Command Line subsection, and be sure to:

a) set Custom working directory: to be /absolute/path/to/vendor.

b) check “Use alternative configuration file:” and set it to /absolute/path/to/vendor/your_app/(sub_app_if_applicable)/phpunit.xml.dist

Then you can run any test class in the suite by specifying the class and file, or just check “Defined in the configuration file” to run all of them according to the config.


I ran into the same issue. If you are using yii2/phpStorm, try to select codeception.yml instead unit.yml under ‘alternative configuration file’ in the debug configuration section.
