My new reinforcement on C++ unit test

A few weeks ago, while I was working out on CppUnit in unit testing and I found out that it wouldn’t work as I doesn’t have MFC framework install in my Windows. Now I had discovered Boost.Test for this critical mission. The first contact on the new discovery, I have following code ready to charge:

#define BOOST_TEST_MODULE Hello
#include <boost/test/unit_test.hpp>

int add(int i, int j)
{
    return i+j;
}

BOOST_AUTO_TEST_CASE(Case1)
{
    BOOST_CHECK(add(2,2) == 4);
}

Interestingly, the test doesn’t get executed, but the main entry point of the program, int main(int argc, char* argv[]) was called. I spent the whole day reading through the documentation still has not got any clue on it. Until I remove the main entry point, and something were shown on the screen:

Running 1 test case...

*** No errors detected
Press <return> to close this window...

This is pretty exciting as I got a first unit test up and running. Thinking out from the plan, I need a separate project just for the unit test.
