Thanks @nansP your solution worked perfectly! Basically my problem with the guide provided by ericlemes was that it wasn’t building properly the solution but with your method GitHub - NansPellicari/UE4-GoogleTest: A simple third-party library for UE4 to use the Google test it worked like a charm.
Also, great work with reports! That could be extremely useful with continuous integration. Do you have perhaps also some game code with tdd to show? It would be nice to see how someone else is mocking and implementing tdd with Unreal.
