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 an RNG which accepts int to random_shuffle. Inside random_shuffle, the STL tries to call that RNG with the difference_type of the user provided iterators. For std::vector, this is ptrdiff_t, which on amd64 builds is wider than int. This triggers a narrowing warning because the 64 bit difference is being truncated to 32 bits. Note that this RNG implementation still does not produce a correctly uniformly shuffled result -- it's currently asserting that std::rand can produce 1000000 which is false -- but I don't know enough about how much repeatable shuffles are necessary here, so I'm leaving that alone for now. |

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.
