Visual Regression Testing for docs migration

Usage

First, run:

npm install

YQ

You'll need yq in order for the script to deal with the sitemap xml files when it dynamically builds your testing paths for you:

brew install yq

Your Paths

You only need to update the ./tests/template-paths.js file if there are changes you have made that are outside the area you indicate as the base path. Make sure each object has a label and a path property. The label should be unique; the path should be the path to the URL endpoint that should be tested and should not start with a /.

scenarioPaths.paths = [
    {
      "label":"Security Project Isolation",
      "path": "security/project-isolation/"
    } 
];

It's important that each path does NOT start with a leading /. If you dont have any extra testing locations, you can make scenarioPaths.paths an empty array:

scenarioPaths.paths = [];

PR URL

Grab the PR Url as indicated in the PR comments or grab it from the platform CLI tool. You only need the main environment URL, not the one for upsun.

Base path

The section you have updated and need to test. If we were updating the content under the https://docs.platform.sh/learn/ area of the docs, then the base path you enter would be learn

Run the tests

To kick it off run:

./run-tests.sh

It should ask you for the PR Url, the base path of the site that should be tested, and then double-check to make sure you've updated the template-paths.js file. It will then create reference files for docs.platform.sh, then run tests against the PR version. If there are issues, it will let you know and ask if you want to see the VRT report. Then it'll prompt you to continue to the Upsun test.

Example:

❯ ./run-tests.sh
PR environment URL for docs.platform.sh? https://upsun-migrate-glossary-y6u355a-ucq44jg6ofare.eu-5.platformsh.site/
What is the base path we are updating? learn
Have you updated the template-paths.js file in the tests directory? Y/n: y
