Function definition for "MOCK_METHOD0" not found when using gmock with C++ RRS feed

  • Question

  • Hello all,

    I have the below original file that has class and structure.


    struct windows_data
    std::wstring computer_model;
    std::wstring computer_name;
    std::wstring computer_manufacturer;
    class windows_interface
    virtual void read_windows_data() = 0;
    virtual ~windows_interface();

    std::wstring get_wmi_interface();

    To use gtest and gmock, i followed the below approach:


    #include "stdafx.h"
    #include <Windows.h>

    #include "gtest/gtest.h"
    #include "gmock/gmock.h"
    #include "test_all_modules.h"

    int main(int argc, char **argv) {
    ::testing::InitGoogleTest(&argc, argv);
    ::testing::InitGoogleMock(&argc, argv);
    int result = RUN_ALL_TESTS();
    return result;


    #include "gtest/gtest.h"
    #include "gmock/gmock.h"
    #include <string>
    #include <system_error>

    using namespace ::testing;

    class test_windows_data : public ::testing::Test
    test_windows_data() {};
    ~test_windows_data() {};
    void SetUp() override {};

    In the below file I am using the gtest to call the original function and to test the structure variables.
    Is it the correct way to test the structure variables using gtest?

    And also I am using gmock by creating the mock class.

    But when I am using MOCK_METHOD0, it is showing Function definition for "MOCK_METHOD0" not found.
    Do I need to define the "MOCK_METHOD0"? If so, please help me how to define?

    Could anyone please help me how to resolve?

    I am using gtest and gmock version 1.8.1. And properly pointing to correct lib and include files.


    #include "stdafx.h"
    #include "test_all_modules.h"
    #include "gmock/gmock.h"
    #include "gtest/gtest.h"

    using namespace MyTest;
    TEST_F(test_windows_data, test_windows_data_default) 
    windows_data windows_data_obj;  // structure
    std::wstring ptr_windows_interface = get_windows_interface();
    windows_data_obj = ptr_windows_interface->read_windows_data();

    EXPECT_GT( windows_data_obj->computer_name.length(), 0);
    EXPECT_GT( windows_data_obj->computer_manufacturer.length(), 0);
    EXPECT_GT( windows_data_obj->computer_model.length(), 0); 

    class mock_windows_interface : public windows_interface {
    MOCK_METHOD0(read_windows_data, void());
    mock_windows_interface mock_windows;
    TEST(mock_windows, test_windows_data_default) {

    EXPECT_CALL(mock_windows, read_windows_data());

  • Hi,

    Thank you for posting here.

    Our forum is discussing about Visual C++ IDE, since your issue contains gmock, it is likely that it is beyond our support. so we suggest you could open a new thread in stack overflow with c++, gmock,google test tag for better support.
