Hi @esa-irri @Rob ,
I will try to answers all test site related questions raised here:
Test site allows you to test your editor changes in a production environment before going live. Your can view your pages and interact with your site and live data, share the link of the test site version with other team members and get feedback on your editor updates. You can also expose the test site version to some percentage of your visitors, before publishing to all.
If you continue to work in the editor after creating a test site, it will not affect the already existing test site version. In order to have a test site version that includes these changes, you have to create a new test site, that will replace the previous version.
Test site doesn’t allow you to work on multiple versions of your site. We have another feature called site branches, which allows you to work on an additional versions of the site, while at the same time being able to make changes to the existing one. Site branches is currently in alpha mode, and is not available in EditorX. If this might be relevant for you and you wish to join the alpha program, let me know.
