Boost Unit Testing and Visual Studio 2005/Visual C++ and the BOOST_AUTO_TEST_SUITE(stringtest) namespace?

Question

I'm reading this article on the Boost Unit Testing Framework.

However I'm having a bit of trouble with the first example, my guess is that they left something out (something that would be obvious to hardcore C++ coders) as IBM often does in their articles. Another possibility is that my Visual Studio 2005 C++ compiler is just too old for the example.

#include "stdafx.h"
#define BOOST_TEST_MODULE stringtest
#include <boost/test/unit_test.hpp>
//#include "mystring.h"

BOOST_AUTO_TEST_SUITE(stringtest) // name of the test suite is stringtest

BOOST_AUTO_TEST_CASE(test1)
{
  /*
  mystring s;
  BOOST_CHECK(s.size() == 0);
  */
  BOOST_CHECK(0 == 0);
}

BOOST_AUTO_TEST_CASE(test2)
{
  /*
  mystring s;
  s.setbuffer("hello world");
  BOOST_REQUIRE_EQUAL('h', s[0]); // basic test
  */
   BOOST_CHECK(0 == 0);
}

BOOST_AUTO_TEST_SUITE_END()

To me the BOOST_AUTO_TEST_SUITE and BOOST_AUTO_TEST_CASE lines look a little suspect (especially since they don't have quotes around the arguments, and they are undeclared identifiers...but this probably means they are macros and I'm not certain I understand the concept or if that is available in VC++ 8.0)...

#ifdef _MYSTRING
#define _MYSTRING

class mystring {
   char* buffer;
   int length;
   public:
      void setbuffer(char* s) { buffer s = s; length = strlen(s); }
      char& operator[ ] (const int index) { return buffer[index]; }
      int size() {return length; }
}

#endif

Is there any reason why this code won't work?

Answer 1

Looks correct to me. My Boost.Test code looks the same way. I'm running VS2008, but I know it works in 2005 as well.

Seems like your problem lies elsewhere. If you use precompiled headers (and why do you do that in such a small test program?), shouldn't stdafx.h be included as the very first thing in the file?

And what is the first line for? You don't seem to use it, and _MYSTRING is a reserved name in C++ (everything that begins with underscore followed by a capital letter is off limits)
