unittest module uses programResult to report number of failures which can wrap

[onqtam]

the exit code of a program can wrap at values as low as 256 (for some platforms) so depending on the exit code of a program for the number of failed tests can be misleading - and might even wrap to 0 - as if no tests have failed!

typically testing frameworks return either success or failure (meaning 0 or 1) - see these links:

In addition to that, I don't like system.programResult, other languages don't have the need for it either.
