Cannot run performance test

Created on 6 August 2025, 25 days ago

I'm trying to run my first performance DTT test. I've only copied the ExamplePerformanceTest in my code base and fixed the namespace. I'm using the ddev-selenium-standalone-chrome DDEV add-on. But when I run the test, I'm getting"

Behat\Mink\Exception\DriverException : Could not open connection: Could not start a new session. No nodes support the capabilities in the request

WHats your version of drupal/core-dev? Some googling suggested you must be very recent on your webdriver packages.

I don't have drupal/core-dev as dependency. That dependency is specifically designated to test Drupal core.

Ah right, ignore that. ddev-selenium-standalone-chrome recently got a release to start using the W3C proptocol. Perhaps try upgrading to latest release there. And make sure your drupal/core is up to date.
