For doing the unit tests Google Test framework is to be used.
The Google Test can be found at https://code.google.com/p/googletest/downloads/list (version 1.7.0 was tested) . You should put the extracted contents alongside your Code Trainer frameworks, to have an example hierarchy like this:
#!c++ -- C:\Code ----- CodeTrainer ----- CodeTrainerPlugins ----- gtest
The C:\Code\gtest folder should contain something like this:
#!python test build-aux src cmake scripts codegear samples msvc make fused-src include m4 xcode CONTRIBUTORS Makefile.am Makefile.in configure.ac README configure CMakeLists.txt CHANGES aclocal.m4 LICENSE
After this, you should launch buildall.bat (or buildall.sh) and it should detect automatically that you have available the Google Test framework. This will result in building the currently minimal unit tests.
After building, you should go into install directory and you will find an executable "unit_test.exe". You can launch this and see the unit tests execute.
