Headless Chrome Service

Note: You may want to take a look at the ddev-selenium-standalone-chrome add-on for this situation.

This recipe allows you to configure a Headless Chrome which will be available inside the web container, at chrome:9222.

I moved from selenium + Chrome to Headless Chrome because it's faster than Selenium + chrome.

  1. Copy docker-compose.chrome.yaml into your project's .ddev directory.
  2. ddev start
  3. Begin testing. An example scenario is below if you don't have anything set up yet.

An example of how to use this is provided in behat blog post:

  • ddev composer require --dev behat/behat dmore/behat-chrome-extension drupal/drupal-extension bex/behat-screenshot to install the needed tools if not already in your project.
  • Copy the example behat.yml provided here into the root of your project (it will be /var/www/html/behat.yml inside the container).
  • Edit "base_url" under Drupal\MinkExtensionin the behat.yml. Use the http URL for your project rather than https because the chrome container does not trust the mkcert certificate used in the web container.
  • ddev ssh to get into the container and work in /var/www/html (which is the root of your project).
  • vendor/bin/behat --init
  • Copy first-test.feature into the features directory that has just been created in the root of your repository.
  • behat (inside the container) or ddev exec behat on the host will test first-feature (which works on a default Drupal 9 profile install)
