Getting following error when running core functional test with PHPUnit:

vendor/bin/phpunit -c core/phpunit.xml core/modules/user/tests/src/Functional/AccessRoleUITest.php

There was 1 error:

<!-- TODO set printerClass="\Drupal\Tests\Listeners\HtmlOutputPrinter" once
 https://youtrack.jetbrains.com/issue/WI-24808 is resolved. Drupal provides a
 result printer that links to the html output results for functional tests.
 Unfortunately, this breaks the output of PHPStorm's PHPUnit runner. However, if
 using the command line you can add
 - -printer="\Drupal\Tests\Listeners\HtmlOutputPrinter" to use it (note there
 should be no spaces between the hyphens).

I have followed Running PHPUnit tests to configure Phpunit.xml, What else I am missing here ?

  • can you post what changes you made to get it to work? – powpow12 Mar 24 at 15:52

I think this is because it's not picking up the port number from your mysql host. I had the same issue and by using a mysql connection on the default port (3306) it started working.
