I use it and I call it approval testing. I make up the input for the test and approve it if I like it. Ideal for GUI while I wouldn't do it for logic where it is better to decide the expected outcome first and let that deive rhe solution, aka TDD.
The thing with GUI is that there are so many curved balls that get thrown at you so you need to look through the GUI quickly. I use Backstopjs that runs my app, take snapshots for different screen sizes and reports the difference from earlier approved snaps. It is a visual report that highlights the difference. It is a quick thing to do.
It has helped me when I upgraded the framework I'm using. However, there's still the problem with the asynchronous rendering browser does. When is it done?

yep this is mostly how we used it for our UI, we had a tool take snapshot and highlighting the differences. was quite cool. but only when we were making changes to the code ( refactoring the framework) and no visual changes were supposed to happen. as soon as we started working on the UI, adding buttons, removing graphics etc, it was a bit of a pain to maintain all the screenshots

We're a place where coders share, stay up-to-date and grow their careers.
