Hi Eduard!
> And who exactly are the intended users of this package? > > Due to features mentioned at long description of the package, CxxTest is designed to be more lightweight than other testing frameworks (like CppUnit). Thus, it is a good alternative for embedded systems where Run-Time Type Information (RTTI) or exception handling are not supported by certain compilers. I have test both CppUnit and CxxTest and IMHO, writing unit test is easier in CxxTest. We are using it on ANSI C and C++ projects with a good results. Others [1] use CxxTest too. Moreover, we have integrated it in the "atheist" (deb package) testing framework. [1] https://software.sandia.gov/trac/acro/wiki/Development/Resources
