Remove hard coded parameter ( drupal_url )

[martinfrances107]

Just making notes in public while I look over this module.

run-js-tests.sh

has a hardcoded value -- which I want to make more generic

php core/scripts/run-tests.sh
--url http://web
--dburl mysql://root:${MYSQL_ROOT_PASSWORD}@db/${MYSQL_DATABASE}
--php /usr/bin/php
--types "PHPUnit-FunctionalJavascript"
--module $MODULE_NAME

I think the url parameter should be drupal_url

see group_vars/dropwhale.yml
