Our phpunit tests are failing with the following:

PHP Fatal error:
    require_once():
        Failed opening required '/tmp/wordpress-tests-lib/src//wp-includes/class-phpmailer.php'
        (include_path='.:/home/travis/.phpenv/versions/7.1.11/share/pear')
        in /tmp/wordpress-tests-lib/includes/mock-mailer.php on line 2

When troubleshooting, we found two things:

The path where class-phpmailer.php is trying to be loaded from, /tmp/wordpress-tests-lib/src//wp-includes/class-phpmailer.php is wrong, it should be /tmp/wordpress/wp-includes/class-phpmailer.php

For the tests themselves, when using the 5.2 branch instead of trunk, it works, it seems like something changed recently to cause this.

Thanks!

Hi there, welcome back to WordPress Trac! Thanks for the report.

Are you using the wp scaffold plugin command? This appears to be the same issue as in comment:15:ticket:48082.

In 47201:

Tests: Revert the dirname( __FILE__ ) replacement in wp-tests-config-sample.php for now, to avoid breaking unit tests created with WP-CLI scaffold command.

Follow-up to [47198].

Props kaggdesign, danielbachhuber, bwmarkle.
Fixes #48082, #49377.
