<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Some phpunit jobs take really long because they execute dozens (or hundreds or...) of tests and assertions and the job takes too long, maybe even times out.</p>
<p>It'd be great to leverage parallel run within the same job. The library <a href="https://github.com/paratestphp/paratest">https://github.com/paratestphp/paratest</a> offers exactly that with minimal configuration, so it'd be worth exploring it.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>If you want to test it, all you need to do is to add the following at the bottom of your .gitlab-ci.yml</p>

<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Maybe consider adopting the new package as the way to run the tests to leverage multicore server runners. Not sure if this needs to bubble up to "core" for discussion or if "contrib" space can go with this approach regardless.</p>
