add support for mocking C++ static class member methods

and start over clean. This is really useful when wanting to test a function in
|

an iterative manner with different arguments.

C++ Support
|
||||
---------
|
||||
C++ unit test/mocking frameworks often use a completely different approach (vs.
|
||||
CMock) that relies on overloading virtual class members and does not support
|
||||
directly mocking static class member methods or free functions (i.e., functions
|
||||
in plain C). One workaround is to wrap the non-virtual functions in an object
|
||||
that exposes them as virtual methods and modify your code to inject mocks at
|
||||
run-time... but there is another way!
|
||||
|
||||
Simply use CMock to mock the static member methods and a C++ mocking framework
|
||||
to handle the virtual methods. (Yes, you can mix mocks from CMock and a C++
|
||||
mocking framework together in the same test!)
|
||||
|
||||
Keep in mind that since C++ mocking frameworks often link the real object to the
|
||||
unit test too, we need to resolve multiple definition errors with something like
|
||||
the following in the source of the real implementation for any functions that
|
||||
CMock mocks:
|
||||
|
||||
#if defined(TEST)
|
||||
__attribute__((weak))
|
||||
#endif
|
||||
|
||||
To address potential issues with re-using the same function name in different
|
||||
namespaces/classes, the generated function names include the namespace(s) and
|
||||
class. For example:
|
||||
|
||||
namespace MyNamespace {
|
||||
class MyClass {
|
||||
static int DoesSomething(int a, int b);
|
||||
};
|
||||
}
|
||||
|
||||
Will generate functions like
|
||||
|
||||
void MyNamespace_MyClass_DoesSomething_ExpectAndReturn(int a, int b, int toReturn);
