A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch)

It checks Knuth's _close enough with tolerance_ relationship, that is `|lhs - rhs| <= epsilon * max(|lhs|, |rhs|)`, rather then the _very close with tolerance_ relationship that can be written down as `|lhs - rhs| <= epsilon * min(|lhs|, |rhs|)`. This is because it is the more common model around the internet, and as such is likely to be less surprising to the users. In the future we might want to provide the other model as well. Closes #1746 |
