C++ code to test another .cpp if its possible to compile it

I would like to ask if there is any good tool for create a code for testing another code if its possible to compile it without errors.

I am coding app in C++ and Qt for testing another codes.

Have you got any recomendation ? I was thinking if it would be possible to use QProcess with assert() somehow. But I want to know more possibilities.

Thank you and have a nice day.
