google mock EXPECT_CALL return value

I have the following code in C want to be test in using google testing framework:

a.h

void getValue(int age, int * value);

a.c

#include <a.h>

void getValue(int age, int * value)
{
   value[0] = 0;
   value[1] = 1;
}

b.c

#include <a.h>

void formValue()
{
   int value[2];
   getValue(age, value);

   /* the code to handle the value[] array */
   /* for() */
}

I want to test the function void formValue() in file b, so I created the following mock for void getValue(int age, int * value): // AFileMock.hh #include #include "a.h"

class AFileMock {
  public:
    AFileMock();
    ~AFileMock();
    MOCK_METHOD1(getValue, void(int, int *));
};

then in the test file I want to call the mocked function getValue and return the value for the void getValue(int age, int * value) part, but how to return the out coming parameter of value array when call a mock function?

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

#include <b.h>
#include <AFileMock.h>

using testing::_;
using testing::Return;
using testing::InSequence;

class BTest: public testing::Test {

protected:
   AFileMock aFile;

public:
   void SetUp() { }
   void TearDown() { }
};


TEST_F(BTest, test1)
{
   InSequence sequence;
   EXPECT_CALL(aFile, getValue(_, _)).
      Times(1); // when this mock function is called, how to return the value of the array?

   formValue();
}

so in this case, when the mock function is called, how to return the value of array?

I cannot understand your sample code, a.c doesn't even compile. But I guess the answer you are looking for is Gmock Actions. A rich set of them is provided.
