You can't avoid manually testing the frontend anyways. In my experience there is a small part that benefits from automated tests but the vast majority of frontend code needs to be looked at and interacted with by a human being, preferably people who are really good testers. I work with someone who does this _really_ well, he finds stuff (very quickly) that your typical user/client just wouldn't - and all the other stuff as well. We sometimes joke about how cool it would be if we were able to encode this in automated tests somehow. A good tester knows their users and knows the tech well enough to find anything that could break that communication between them. Some of that you can encode in acceptance tests - after the fact. But the tricky things you just can't. You have to interact with it, discuss it, look at it from different angles and try to break it - play.

This is why I use frontend error tracking tools (Rollbar, Sentry, LogRocket, take your pick) to notify me when there are edgecase errors. There are too many combinations of browsers and settings to really rely on any sort of manual frontend testing. It is definitely a case of letting your users test for you, but if you've got notification of thrown exceptions, then now you have a chance of fixing things. Getting rid of frontend unit testing is a huge mistake though. I don't blame people for doing it. Testing frontend is poorly documented and misunderstood. It took me hours of research to even figure out how to do it myself. That said, I did it. It works. I've proven it works over many years of doing frontend development. Don't use initial difficulty as an excuse to not do it.

There's a difference between regression testing and exploratory testing. For regression testing, stuff that gets repeated every release is hard to catch by human eye, especially as releases get more and more frequent. Automating rote regression testing just to ensure that what works yesterday still works today is a great way to ensure that the manual testing is about to focus on exploratory testing only
