Replace C++ Igloo with a better testing framework

Voileexperiments commented 5 years ago

I'm looking at Igloo and there are lots of problems with it:

Very outdated (last commit is 3 years ago) and definitely out of support
Very poor documentation: no docs at all except an example at official repo, the official domain for the project is expired, what's remaining is an (official?) wordpress site, but that doesn't show much at all either
Outdated in terms of C++ version: CW is using C++14, and Igloo isn't even aiming for C++11 (so no lambdas and such). In fact the recommendations for Igloo I've seen are... mostly back in 2010
Section names are forced to be a valid token in the language. Ideally section names should be arbitrarily, like a string

I'm looking at a wide range of C++ test framework and it seems that Catch2 is a nice replacement. Header-only, light-weight, does the same thing, supports strings as section names, support predicates and such. RapidCheck, a C++ QuickCheck clone, also uses Catch within itself.

googletest and boost.org test are two that are actively maintained and fairly popular too. But I really want want arbitrary section names, so I personally likes Catch2 more.

I've been wanting to replace with Catch2. It has a way to customize the output as well (considered unstable at the moment).

It'll get done eventually because it's needed for Qualified. I'll worry about how to handle converting Codewars contents later.

And thanks for RapidCheck!

Indeed, Igloo is horrible. It's near to impossible to create custom error messages, something even the clunky C Criterion test framework is able to do. And documentation is severely lacking.

The proposed Catch2 at least support custom error messages. And documentation seems OK.
