Quick and easy tip, sometimes a test could take too much time/memory, you can set your local environmentmemory_limit, but take in mind that you should repeat this process on every environment (local, staging, production) and all development team environments should add this configuration, not best solution right?

Fortunately.PHPUnit provides a simple solution for this cases you can set amemory_limit value that would instruct the memory limit only when the app runs tests.

In yourphpunit.xml file add this configuration:

<php> ...<ininame="memory_limit"value="512M"/></php>
