I wrote a DLL with inline implementations. I'm pretty new to Unit Tests in C++, so I added some as described here and they just worked perfectly fine. Assertions were reacting correctly etc.
After extracting the methods in their .cpp for reasons, I learned that the class has to be exported (LNK2019, LNK2001). Or at least the methods which should be able to be tested. But exporting methods expecting fe. std::string or STL containers as an argument, or even members of another class causes trouble with C4251, what I wanted to avoid with #4 from here (TL;DR export everything else as well - does not work: C2242).
It's possible to ignore the C4251 but then the tests are failing with an C000005 exception and the following stack trace:
Error Message: Exception Code: C0000005 Stack Trace:

But that evolved already in directions where I never wanted to go. Is there any solution for my issue? Like test project config or sth.? Do I have to change the test framework?
