C++ Unit Testing and stubbing a 3rd party C library

Question

I need to unit test some C++ objects that I've written that use a 3rd party C library. For reasons beyond the scope of this question, I can't call the 3rd party C library directly, and need to stub it out for the test suite.

For other parts of our unit test suite we use googlemock , but I don't think it can be used for C libraries. I can stub out the library manually, but prefer not to (partly due to laziness (its rather large), but mainly because its just a matter of principles).

So here's my question: is there a tool that generates stubbed code based on a C library header file? Once I have the stubbed-out code, I'll do some minor mods to it, then I'll link against it for the unit testing.

Answer 1

stubgen可以从头文件生成存根成员，除非你有特殊要求，它应该能够做你想要的。

Answer 2

You cant wrap those calls in a class like described in http://code.google.com/p/googlemock/wiki/CookBook#Mocking_Free_Functions

Then You can inject (in dynamic or static way) this class and set expectation on it.
