In my opinion, the way that most unit tests are written is mostly a waste of effort, but there are a class of unit tests that are much better suited to the task. The class of unit tests I'm referring to is property-based tests.
The most famous property-based testing framework is QuickCheck, but there are plenty of others, e.g. FsCheck for C#/F#, ScalaCheck for Scala, Hypothesis for Python, etc...
The general idea being that you write out a specification that the code should meet, and the test parameters are determined at runtime, rather than being hardcoded. There's more to it than that, but that's the general idea. If you want a simple introduction, I'd recommend this video:
