How to configure a new Project with googlemock

[fr4ncois]

Hi,

I'm trying to create a new project with Visual C++ 2005 to test
googmock with a little example, but i can't build it, I get always
those errors :

d:\documents and settings\fxschauber\my documents\visual studio
2005\projects\mockpptest\mockpptest\mockpptest.cpp(23) : error C2660:
'MockTest::gmock_Tutu' : function does not take 0 arguments
d:\documents and settings\fxschauber\my documents\visual studio
2005\projects\mockpptest\mockpptest\mockpptest.cpp(23) : error C2228:
left of '.InternalDefaultActionSetAt' must have class/struct/union
d:\documents and settings\fxschauber\my documents\visual studio
2005\projects\mockpptest\mockpptest\mockpptest.cpp(24) : error C2228:
left of '.WillByDefault' must have class/struct/union

I tried to link gtestd.lib but then i get some multiple definition
errors.

thanks,
François

Hi François,

Can you please post the code you are trying to compile?

Thanks,
Vlad

[fr4ncois]

yep, thanks

#include "stdafx.h"
#include <gtest/gtest.h>
#include <gmock/gmock.h>
using namespace testing;

class TestGM {
public:
virtual ~TestGM() {}

virtual void Toto() = 0;
virtual int Tutu(bool flag) = 0;
};

class MockTest : public TestGM {
public:
MOCK_METHOD0(Toto, void());
MOCK_METHOD1(Tutu, bool(int n));
};

TEST(bla, bli) {
MockTest test;

ON_CALL(test, Tutu())
.WillByDefault(Return(1));


}

int main(int argc, char** argv) {
// The following line must be executed to initialize Google Mock
// (and Google Test) before running the tests.
testing::InitGoogleMock(&argc, argv);
return RUN_ALL_TESTS();

}

 virtual void Toto() = 0;

Here you are providing a default action for mock Tutu() to perform  when invoked. The problem here is that Tutu is declared as receiving an integer parameter, and you have to provide a matcher for that parameter. Otherwise the compiler will not be able to find the method. If you want to provide a default for every call to Tutu regardless of the value its parameter, use the _ matcher:

ON_CALL(test, Tutu(_))....

I am afraid we do not emphasize this enough in the wiki documentation, but when you declare your mock default behavior or expectations you have to provide a matcher for every parameter a method has.I will go ahead and make it clearer there.

Hope this helps,
Vlad

hey,
Thanks for your help, i tried the _ matcher, it seemed to work but
then I saw a mistake i did, I switched the return value and the
argument of the Tutu func. I should have written MOCK_METHOD1(Tutu, int
(bool flag)). But then i get 21 unresolved externals...

any idea?

[Vlad Losev]

All these unresolved references save for one are for googlemock symbols. Have you added a gmock.vcproj reference to your mockpptest project or added gmock.lib explicitly to your linker settings?
You can verify in your saved build log whether your project links in gmock.lib.

Indeed i didn't link the gmock.lib and gtestd.lib correctly..

It's good now, thx for your help.
