Is there one version to support windows?

I am adding gtests for our codes and found your way that may be used. But you said you had tested it only on mac. Is there one version to support windows? We are now using VS2015 update3.

Thanks.

Compiling fails with error " invalid initialization of non-const reference of type ‘testing::internal::MockSpec.."

Hello,
I am trying to run the example present in "https://github.com/gzc9047/CppFreeMock/tree/master/example".

I am using google test release version - googletest-release-1.8.1

Steps performed:
1.)Download the "CppFreeMock" repository and placed it on my SUT
2.)Navigated to Examples folder and modified the Makefile to update paths to my libraries and include files as follows:

TMPDIR=..
PROJECT_ROOT=..
GMOCK_LIB = -L/opt/gtest/lib
GMOCK_INCLUDE = -I/opt/gtest/include -I/usr/include/gtest/ -I/usr/include/gmock/ -I$(PROJECT_ROOT)

3.)Executed make as below:

[root@SUT example]# make all
g++ -g -O0 -std=c++11 -fno-inline -falign-functions=32 test_member_function.cpp -I/opt/gtest/include -I/usr/include/gtest/ -I/usr/include/gmock/ -I.. -L/opt/gtest/lib -o ../test_member_function.out

Not sure what I am missing..
Any guidance on same will be helpful..

Mock std::abort meet problem.

When mocker function of abort return, program don't run the code just after it, it's run unexpected.
If add "return 0;" after https://github.com/gzc9047/CppFreeMock/blob/master/runtime_patch.h#L46 it don't run.

So find the root cause and fix it.

Add UT for mock constructor and destructor

Move errno usage from runtime_patch.h to posix/runtime_patch_impl.h

Do we need create mocker object explicit?

Such as:
MOCK(func); // instead of CREATE_MOCKER(mocker, func);
EXPECT_CALL(MOCKER(func), MOCKER_FUNCTION(...)).Times(...);

No matter how many time we try to mock the same function, we should always return the same mocker object

I'm trying to implement #15 , there is a way to create anonymous mocker. But multi mocker creation will return different mocker, this is not we want, so we need this issue.

Add UT for member function in large inherit hierarchy. Check mock works and this pointer check works.

Add UT for throw exception in mocker function.

Add some UT for the function implement in *.o

Till now, all the case are for inline function in the source code(except mprotect). Should use some real function.

how to solve overloaded function

Alarm when try to mock a method twice or more

Test on non-posix and non-c++11, just make sure the error message of build is clear

Till now this tool don't support non-posix and non-c++11, so if try to build on them will need compiler error, so just make the error message be helpful.

Add UT for this tool.

This implement code migrate from the prototype, it don't have UT, so we need it.

Member function should always have this point check
