This is a connected to #EZP-21408 as it concerns an installation of eZ Publish legacy with eZ/Zeta Components installed through composer only.

In the given environment (with activated extension ezcomments), eZ Publish's PHPUnit tests fails after a while with the message

Fatal error: Class 'ezcLog' not found in /../vendor/zetacomponents/debug/src/debug.php on line 145

Adding zetacomponents/event-log to the composer.json file fixes this issue.

How to reproduce

• Checkout ezpublish-legacy
• Install Zeta Components with composer install
• Checkout ezcomments
• Copy ezcomments into extension/ezcomments
• Activate extension
• Run the PHPUnit tests
