Experimental setup of Drupal 8 testing for ddev

d8test_setup.sh

#!/bin/bash

# This script runs inside the ddev web container and sets up Drupal 8 testing.
# It assumes a regular Drupal 8 checkout, with the docroot in the project root.
# It can be added to the config.yaml as a step to automatically happen on start

# - Run this manually with "ddev exec ./d8test_setup.sh"
# - Run this in the container (after "ddev ssh) by just running "./d8test_setup.sh"
# - Run it automatically run on start by adding it to the project's config.yaml:
#hooks:
#  post-start:
#    - exec: ./d8test_setup.sh
