I wish I had known earlier in my college days about writing unit tests. It would have made testing my programs a lot easier than manually testing my input all the time instead of having to execute something like this on the command line: ./a.out < testfile_n.
With that being said, I've started to look into some C++ testing frameworks, and one that I've been playing around with is Google's C++ testing framework: https://github.com/google/googletest .
It's nice, but before I start to really get into it, are there some testing frameworks that you guys can recommend me to check out? It seems there are a few out there.
