Bjarne Stroustrup said in a video on CppCon that, one of his desires for the future of the language is to remove the preprocessor ecosystem from the standard.
I am looking for a unit test that is design is not macro based, but I am unable to found anything decent.
Does anyone knows about one?
No decent ones currently exist, because there are still some things that are impossible to do in C++ without macros (e.g. getting a stringified version of an assert expression). Before we can remove our usage of macros, the C++ language needs to evolve. Check back in 10 years.
In the meantime, I recommend Catch2.
