PhpStorm "Test framework quit unexpectedly"

Question

I'm trying to setup PHPUnit tests in PhpStorm.

In Settings > Languagees & Frameworks > PHP > PHPUnit I have chosen the option to use Composer autoload to load PHPUnit.

In Path to script I have put <path to project>/vendor/bin/phpunit.

When I run the test suite I get the error message:

Test framework quit unexpectedly

Answer 1

Path to script should be the path to the composer autoloader.

<path to project>/vendor/autoload.php
