How to run unit test cases in Socket-Client program using C language in eclipse-cdt ubuntu 14.0?

Question

I made simple StringReverse C project in eclipse-cdt (ubuntu 14.0) and made to .so (shared library). I made test cases for StringReverse C project in eclipse-cdt. Tests runs successfully.

But, these C project and test cases I wants to run in Socket-Client Programming in eclipse-cdt. Suppose, I wants to pass test cases in Client side and that test cases find the C function in Server side. How can I make this..?

My StringReverse C code :

Include :

#define LENGTH_OF_STRING 20

#include <stdio.h>
#include <string.h>
#include "error.h"

int StringReverse (char *ptrToDestination, char *ptrToSource);

Source :

#include "StringReverse.h"
#include "error.h"

int StringReverse(char *ptrToDestination,char *ptrToSource)
    {

    int i,j;

    if(NULL == (void *)ptrToSource) {
        return ERR_NULL_POINTER;
    }

    if (LENGTH_OF_STRING <= strlen(ptrToSource)) {
        return ERR_STRING_LENGTH;
    }

    if(NULL == (void *)ptrToDestination) {
        return ERR_NULL_POINTER;
    }

    for(i=0; ptrToSource[i]; i++) {
    }

    for(i=i-1,j=0; i>=0; i--,j++) {
            ptrToDestination[j] = ptrToSource[i];
    }
    ptrToDestination[j]  ='\0';

    if(strlen(ptrToSource) != strlen(ptrToDestination)) {
        return ERR_STRING_LENGTH;
    }
    return SUCCESS;
}

My test case :

AllTests.cpp :

#include "CommandLineTestRunner.h"

int main(int ac, char** av)
{
    int result = RUN_ALL_TESTS(ac, av);

    return result;
}

StringReverse_Test.cpp :

extern "C"
{
#include "StringReverse.h"
#include "error.h"
}

#define COUNT_FOR_NULL 1

#include "TestHarness.h"
#include "TestHarness_c.h"
#include <string.h>

int StatusOfStringReverseFunction;
TEST_GROUP(StringReverse)
{
    void setup()
    {
        /**
          * This method is used to initialize the test. It is runs before each test.
          *
          */
        printf("Tests start here...\n");
    }
    void teardown()
    {
        /**
         * This method is used to finalized the test. It is runs after each test.
         */
        printf("Tests end here...\n");
    }
};

/**

 *

TEST(StringReverse, tst_StringReverse_PointerToString)
{
    char *ptrToSource = "abcdefghijkl";
    char *ptrToDestination = NULL;

    CHECK(NULL != ptrToSource);

    ptrToDestination = (char *)    malloc((strlen(ptrToSource)+COUNT_FOR_NULL)*sizeof(char));

    CHECK(NULL != ptrToDestination);

    StatusOfStringReverseFunction = StringReverse(ptrToDestination, ptrToSource);

    CHECK(strlen(ptrToDestination) == strlen(ptrToSource));
    LONGS_EQUAL(SUCCESS, StatusOfStringReverseFunction);

    free ((void *)ptrToDestination);
}

TEST(StringReverse, tst_StringReverse_Null)
{
    char source[LENGTH_OF_STRING] = "";
    char destination[LENGTH_OF_STRING];

    StatusOfStringReverseFunction = StringReverse (destination, source);

    LONGS_EQUAL(SUCCESS, StatusOfStringReverseFunction);
}

What is the solution ?
