How to add macros to the generated mock files ???

[guillermoarb]

Hi, I wonder for example why CMock does not include in the mock_reference.h created from reference.h the macros that are created in reference.h file.

For example if I am testing test.c then I mock reference.h and inside this there is a definition e.g. #def MASK 0x01 and I want to use it in my unit testing file ut_test.c so the definition is not copied into the mocked version mock_reference.h so then I have to add the #def MASK 0x01 to my test file ut_test.c, if I want it to work. But then I have to maintain to macros with the same value.

Here is a code example, sorry if there is not Ok, is just something quick to explain my question.

reference.h

#def MASK 0x01

test.c

#include reference.h

uint8 check_mask(unit8 input)
{
    return (input & MASK);
}

ut_test.c

#include test.h
#include mock_reference.h

test_TC01(void)
{

ret_val = check_mask(0x02);

TEST_ASSERT_EQUAL_UINT8(MASK, ret_val);  /*This won't compile, MASK is not defined in mock_reference.h */

reset_test( );
}

My generated mocks usually do #include the original header file - what are the first 10 lines of mock_reference.h?

Are you using ceedling? If so, check if the :use_test_preprocessor: is set to FALSE.
Otherwise cmock will receive a preprocessed header, which has all defines/macros/includes/... removed, and so the generated header will also have this stuff removed.
