Top 15 C++ unit-testing Projects

catch2 has become fairly bloated. doctest takes all of the best parts of catch2 without all the bloat and the end result is a test framework that is literally over 10x faster than catch2. It's also like 90% compatible with catch2 so porting your tests to it is pretty easy.
Especially if you have a build process that always runs your unit tests, it's nice to have a very fast test/compile/debug loop.

chessCAMO
chessCAMO is a newly proposed chess engine with a built-in variant that stands for Calculations Always Make Opportunities and was inspired by the very popular chess variant Crazyhouse. The "CAMO" portion comes from the idea that in this variant a player can sacrifice making a move to replace one of their pieces from the "piece reservoir".
