Best practices for final software validation?

[weberstmichael]

Hi all! I'm working on a small media management tool similar to digiKam and reached the stage of user validation. I want to make sure I don't miss any critical feedback before the release. I found this guide on acceptance testing very detailed: https://testomat.io/blog/the-ultimate-guide-to-acceptance-testing/ — does anyone here use automated tools for this, or do you prefer manual beta-testing sessions with real users?
