It could be that my use case was simple enough, but for a class i'm taking, we were tasked with creating some code for a web application, as well as unit tests for it, and while copilot wasn't of much use for coding the actual application, it pretty much nailed autogenerating the test cases.

Now, as i said, this was for a class, so it was simple. Sadly work policies at my employer forbids the use of copilot (or anything transmitting code out of the company), so i can't really test it with "real code",
