//=========================================================================
//  Test Harness
//=========================================================================
// 
//  There are two styles of test in here.  The older ones are vaguely
//  inspired by Kent Beck's book on eXtreme Programming (XP) and use
//  the TEST...() macros.
//
//  But this style is not really appropriate for C++.  It's based on
//  code that explicitly tests for errors, as one would do in C.  In C++,
//  it is cumbersome to catch exceptions on every call, so we don't in
//  the new style.

//  And there's not much point in trying to count test successes and
//  failures.  Any failure is a problem, so in the new style, we just
//  quit after we recognize one (again, more in line with regular exception
//  throwing).  With exception throwing, you can't count what _didn't_
//  cause an exception, so there's no meaningful count of test successes.
//
//  To run the tests, type './cpptest'.
//  To check for memory leaks, install RedHat's 'memprof' utility, and
//  type 'memprof cpptest'.
//
//  If you add new tests to this file, please deallocate any data
//  structures you use in the appropriate fashion. This allows us to test
//  various destructor code for memory leaks.
