When I try to use:

ON_CALL(mock, foo(_))

Compilation error is thrown:

Error   1   error C2065: '_' : undeclared identifier

I am using visual studio 2012.

undeclared identifier always means that compiler does not understand what it (i.e. _) is. So perhaps you forgot

#include <gtest/gtest.h>
#include <gmock/gmock.h>

or

using::testing::_;

Refer to examples and check.
