I haven't heard of the single-assertion thing in at least 10 years, probably 15. In the early 2000s, when I was starting out and doing .NET, it used to be something you'd hear in the community as a very general guideline, more like "there's something to be said about very focused tests, and too many assertions might be a smell." At the time, I got the impression that the practice had come over from Java and converted from a rule to a guideline (hardly the only bad practice that the .NET community adopted from Java, but thankfully they largely did move the needle forward in most cases). (I wrote Foundations of Programming for any 2000s .NET developer out there!) To hear this is still a fight people are having...It really makes me appreciate the value of having deep experience in multiple languages/communities/frameworks. Some people are really stuck in the same year of their 10 (or 20, or 30) years of experience.

> I wrote Foundations of Programming for any 2000s .NET developer out there! Holy moly! Think I still have your book somewhere. So thank you for that. In my last +10 years of .net development I haven't heard anything about single-assertion. > Some people are really stuck in the same year of their 10 (or 20, or 30) years of experience. I think this has manifested even more with the transition into .net core and now .net 5 and beyond. There are so many things changing all the time (not that I complain), which can make it difficult to pick up what's the current mantra for the language and framework.

Like you I was surprised to hear this is a thing or is even controversial. Admittedly I've only been programming for about 10 years, but I haven't heard (or seen) this come up even one time. Every test I've ever seen has usually had multiple mutations and assertions, all of them testing the same premise.
