I guess noone makes a really extensive unit test except for critical applications where they can supply components fully tested and possibly even under rated to achieve better reliability. For development tools could be done the same with special libraries that have run-time range checking or more rigid compile time validators. As far as I know currently only Ada supports that, but I my wrong on this. Tamas On Wed, Apr 16, 2008 at 2:01 PM, Alan B.
