Gmock problem

[manticore]

Hi,

i entounter some problem with the unit testing and gmock.

My objectif is to test some interaction with the filesystem for example if a directory doesn't exist.

Here is a small example method :

bool Foo::foo()
{
	DIR *rep;
	Dirent interface;
	// Aims, test if a exeption append here.
	rep = interface.opendirInt("/home/manticore/Downloads/");
	struct dirent *lecture;

	while ((lecture = readdir(rep)))
	{
		if (strcmp(lecture->d_name,"test.txt") == 0)
		{
			printf("Test found\n");
			return true;
		}
	}
	return false;
}

I have create a interface for the dirent.h :

/*
 * DirentInterface.h
 *
 *  Created on: Jan 16, 2013
 *      Author: Marc Romanens
 */

#ifndef DIRENTINTERFACE_H_
#define DIRENTINTERFACE_H_

#include <dirent.h>

class DirentInterface
{
	public:
		// Prototype: DIR * opendir (const char *dirname)
		virtual DIR* opendirInt (const char *dirname) = 0;
};

class Dirent : public DirentInterface
{
	public:
		DIR* opendirInt (const char *dirname)
		{
			return opendir(dirname);
		}
};

#endif /* DIRENTINTERFACE_H_ */ 

And here is my mock object :

/*
 * MockDirent.h
 *
 *  Created on: Jan 16, 2013
 *      Author: Marc Romanens
 */

#ifndef MOCKDIRENT_H_
#define MOCKDIRENT_H_

#include "gmock/gmock.h"
#include "../../../sourceProject/src/DirentInterface.h"

class MockDirent : public Dirent
{
	public:
		MOCK_CONST_METHOD1(opendirInt, DIR*(const char *dirname));
};

#endif /* MOCKDIRENT_H_ */ 

Finnaly here is my testing code :

  TEST_F(FooTest, foo)
  {
	  MockDirent dirent;
	  EXPECT_CALL(dirent, opendirInt("/home/manticore/Downloads/")).Times(1);//))
	  bool test = foo.foo();
	  ASSERT_TRUE(test);
  }

My objectif is to remplace the call of opendir in Foo::foo() by my mock, but for begin i trying to get EXPECT_CALL, and the test fail, my opendirInt method is never call.

Thanks you, (i'am glad to join this forum).

p.s. Sorry for my poor english ;)
