Cppunit testing ONLY returns Ok(0)

Question

I'm currently doing cppunit testing on my project. The 2 functions checkWord and checkFile both return 'true' bool values when I compile and run the program normally. Then when I use these 2 functions for my cppunit testing. The output result will always be OK(0). Instead of the OK(1) I should be seeing when i run either of the CPPUNIT_ASSERT(). Anyone can help me with this?

Below are my codes for the project:

checkWord function

bool ScrambleWordGame::checkWord(string checkWord) {
ifstream file("WordDatabase.txt");
vector <string> wordList;

copy(istream_iterator<string>(file),
     istream_iterator<string>(),
     back_inserter(wordList));   
file.close();    

if(find(wordList.begin(),wordList.end(),checkWord) != wordList.end())
    return true;
else 
    return false;
}

checkFile function

bool ScrambleWordGame::checkFile(string filename) {
ifstream file(filename.c_str());
if(file)
    return true;
else 
    return false;
file.close();
}

SWGTest.cpp

#include "ScrambleWordGameTest.h"
#include "ScrambleWordGame.h"

void ScrambleWordGameTest::testEquals() {
  CPPUNIT_ASSERT(swg.checkFile("WordDatabase.dat"));
//CPPUNIT_ASSERT(swg.checkWord("cat"));
}

Turns out that Registration for the test case is missing. Therefore, the following line is needed in the testclassname.cpp

CPPUNIT_TEST_SUITE_REGISTRATION (testclassname);
