Feature Request: Add CI test for docker-entrypoint.sh #511
Description
Describe the Feature Request
Add CI testing for the Xvfb script in docker-entrypoint.sh.
Is your feature request related to a particular problem?
The CI config .circleci/config.yml does not test the functionality of the docker-entrypoint.sh script used in cimg/node:*-browsers images. It is possible for PRs making changes to this script to pass CI tests and cause downstream issues. For example PR #499 caused the essential DISPLAY environment variable to be removed. If this had been included in any released image it would have caused hard failures in Cypress pipelines using new images.
How will this feature request benefit CircleCI jobs using this image?
It will help prevent the release of images with bugs in the docker-entrypoint.sh script
Describe the solution you would like to see
Build an image and test the script docker-entrypoint.sh in CI when PRs are submitted and commits are merged into the default branch.
Describe alternatives you have considered
The only current alternative is to manually build a Docker image from a PR branch and then manually test it.
