Add Chromedriver as a JavaScript dependency

This was deliberately removed, because some people are not using the drupalci/chromedriver container and run tests with other versions of Chrome, so it is left up to you to install the correct version of chromedriver now for local development. See https://www.drupal.org/node/3319135 →

Thanks @longwave

Yes, you are right about running Nightwatch, but this is also used for running PHPUnit's Functional Javascript Tests, and the current (recommended) image for this is chrome=106.0.5249.103)

e.g.

image: drupalci/chromedriver:production

As the name implies, that container includes chromedriver (as well as Chrome); configure Mink to connect to the container on port 9515 where chromedriver runs, you don't need to run it separately.

See https://www.drupal.org/docs/automated-testing/phpunit-in-drupal/running-... → for an example based on Docker Compose.

Thanks @longwave.

You are right. I have updated my docker-compose.chromedriver.yaml file as per the instructions on the link you gave when running with ddev. e.g.

version: '3.6'
services:
  chromedriver:
    container_name: ddev-${DDEV_SITENAME}-chromedriver
    image: drupalci/chromedriver:production
    shm_size: '1gb'
    ulimits:
      core:
        soft: -1
        hard: -1
    ports:
      - "4444:4444"
      - "9515:9515"
    entrypoint:
      - chromedriver
      - "--log-path=/tmp/chromedriver.log"
      - "--verbose"
      - "--allowed-ips="
      - "--allowed-origins=*"
    labels:
    # These labels ensure this service is discoverable by ddev
      com.ddev.site-name: ${DDEV_SITENAME}
      com.ddev.approot: $DDEV_APPROOT
      com.ddev.app-url: ${DDEV_PRIMARY_URL}
      
  # This links the Chromedriver service to the web service defined
  # in the main docker-compose.yml, allowing applications running
  # in the web service to access the driver at `chromedriver`.

    links:
      - chromedriver:$DDEV_HOSTNAME

Also removed chromedriver from core/package.json and re-ran yarn.

Tests also appear to be running a bit quicker now.
