This is the 18th video in the Getting Started with Rails 7 series. In this video Mike adds the ability to delete comments. Similar to article deletion, he needs to make sure the Turbo confirm and :see_other status are configured correctly. In order to test this he uses browser-driven Rails system tests.

• 00:18:55 Troubleshoot invalid match in browser test part 2.
• 00:23:38 Add dom_id helper to comment partial to identify the comment to destroy
