Unit Tests are still underrated in my experience. It pains me when I see developers testing their functionality end to end, manually. Discover a formatting error in their input, then do this again. When I was working in the office I could see that easily 90% of a lot of developer's time is spent like this. Then I showed that a unit test can discover this, people are still in denial, that it was just for this small error. But software development is a lot about nitty gritty details. And unit testing fixes this.
