Forked from cppfreemock, based on gmock, can mock global function, member (virtual/nonvirtual) function, class static function without change source code.

What you have to do:

• include easymock.h into you test source file
• if using googlemock please make sure that you have included the easymock.h after #include<gmock/gmock.h>
• create a mocker to a desired function using CREATE_MOCKER(&...) macro
• on the created mocker do a expect call using gmock EXPECT_CALL(...) macro
• after calling method or function under test make sure that you've cleared the mocker created using DISABLE_MOCKER(mocker) or CLEAR_MOCKER(mocker)

Hello world example:

string func() {
    return "Non mocked.";
}

TEST(HelloWorld, First) {
    EXPECT_CALL(*CREATE_MOCKER(func), MOCK_FUNCTION()).Times(Exactly(1)).WillOnce(Return("Hello world."));
    EXPECT_EQ("Hello world.", func());
}
