nmtest is a small C++ library for writing unit-tests without the need for any macros. I made it mainly as an experiment to see if modern C++ (23 in this case) could provide all the needed functionality.

The journey, including the general design of the library and the motivation behind, it are presented here:

• Macro-free unit-testing framework in modern C++
• Exploring macro-free testing in modern C++

It provides a pretty simple way of registering tests, organizing them into suites and running them with optional filtering.

• Source code consists of a single C++23 module.
• Readme file gives a more in-depth look at the library and its interface.
• dough is an earlier attempt at creating a similar testing library. Also comes with a readme.
