Add automated test for "Space Rights Show Users and Groups"

The manual test is here: Space Rights Show Users and Groups.

The test verifies if the list of Users and Groups is displayed properly in Page Administration.

Ilie Andriuta: Hi! Continuing the manual tests migration, there is a test about checking if the list of Users and Groups is displayed properly in Page Administration: https://test.xwiki.org/xwiki/bin/view/Administration%20Tests/Space%20Rights%20Show%20Users. I've checked https://github.com/xwiki/xwiki-platform/blob/2d9450e8e8b3e3a4f2a5dc05c97116abb27846aa/xwiki-platform-core/xwiki-platform-administration/xwiki-platform-administration-test/xwiki-platform-administration-test-pageobjects/src/main/java/org/xwiki/administration/test/po/GroupsPage.java but I'm not sure automated tests exist. Can you please confirm whether the automated test exists for it or not and maybe providing the link to it? Thanks!

 
Simon Urli: I'd have expected such test to be part of https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwiki-platform-administration/xwiki-platform-administration-test/xwiki-platform-administration-test-docker/src/test/it/org/xwiki/administration/test/ui/UsersGroupsRightsManagementIT.java but apparently it tests only the Administration UI for Groups and Users not for rights
