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)

Catch passes ::tolower into std::transform with string iterators. ::tolower has the signature int(int), which triggers a stealth narrowing warning inside std::transform, because transform calls *_Dest = _Fn(*_First), which implicitly narrows an int to a char. For this particular application the narrowing is fine, so explicitly narrow in a lambda. |

What's the Catch?
Catch stands for C++ Automated Test Cases in Headers and is a multi-paradigm automated test framework for C++ and Objective-C (and, maybe, C). It is implemented entirely in a set of header files, but is packaged up as a single header for extra convenience.
