The following tests need to be written in Cypress:

• Check if post search does not work with EP during full sync

Post Search

Password Protected Content

• If the user is a subscriber, they should be able to the post title displayed on the front page, and on search results.
• If the user is logged out, they should be able to the post title displayed on the front page, but not on the search result

Facets (#2667)

• If user posts an anonymous comment, it should not be synced
• If user approves a pending comment, it should be synced
• If user disables the options "Comment must be manually approved" and "Comment author must have a previously approved comment" on Settings > Discussion and post an anonymous comment, it should be synced.
• If feature is activated, user should see “ElasticPress - Comment” widget in the dashboard.

• If not in ElasticPress.io nor using a custom PHP proxy, user should not be able to enable the feature.
• If using https://github.com/10up/elasticpress-proxy, user should see a warning about security measures
• In the frontend, typing something in a search form and hitting enter should open the Instant Results popup
• Changing filters and search term should update results
• Different taxonomies with the same name but applied to different post types (Categories vs. Product Categories) should have the post type label appended in the filter displayed in the front end

Although #2615 was already merged, we still need to, at least, adapt tests to better reflect the changes we made in the dashboard screen and roughly test Instant Results.

I'm changing the purpose of this issue. Instead of simply tracking the tests that should be added due to changes in 4.0.0, it is now tracking all the e2e tests that we need to implement.
