PhpStorm "Test framework quit unexpectedly"
<p>I'm trying to setup PHPUnit tests in PhpStorm.</p>

<p>In <strong>Settings > Languagees &amp; Frameworks > PHP > PHPUnit</strong> I have chosen the option to use Composer autoload to load PHPUnit.</p>

<p>In <strong>Path to script</strong> I have put <code>&lt;path to project&gt;/vendor/bin/phpunit</code>.</p>

<p>When I run the test suite I get the error message:</p>

<blockquote>
  <p>Test framework quit unexpectedly</p>
</blockquote>
