Re: [Cppunit-devel] How to Test a Module that is dependent on other module?

[CppUnit d. m. l. <cpp...@li...>]

Hello
Ya i got what you wanna say.
But i have another problem....
Suppose i want to create test cases for system calls. for e.g. a call to
createthread()
or to createevent. how to provide test cases for those calls
Suppose i replace those system calls with dummy functions. that's fine but =
i
think it will clash with system dlls. then how do i tackle this problem.

Thanks.
