Dave's Unit Test Description

Dave's Unit Test (DUT) is a simple unit testing infrastructure implemented in c-preprocessor macros and GNU make. Dave's Unit Test (DUT) is a simple unit testing infrastructure implemented in c-preprocessor macros and GNU make.Here are some key features of "Dave s Unit Test":· Test the (non-)equality of any types (including C++ classes) which can be compared using the = operator. · Special purpose tests for the (non-)equality of floating point types allow for a user specified granularity in machine arithmetic. · Built in string comparison tests. · Able to test for the (non-)existence of C++ exceptions and to trap and report unexpected exceptions. · Able to test for the (non-)existence of POSIX signals (i.e. signal (2)) and to trap and report on unexpected signals.CompatibilityDUT has been tested with (and only with) various versions of gcc. As of 1 March 2008, the SVN head works with tcc 0.9.23 as well, but not with nwcc 0.7.5. At this point I do not know if this is a fault in my code or in the compiler.If you know that it does or especially does not work with another compiler, please let me know.Testing with other compilers turned up a miscellaneous "compatibility" issue: the behaviour of various libc function on bad input is not always specified. So on my PowerBook G4 the codechar *str4 = NULL;printf("%cn",str4);throws a SIGBUS signal. But it does not on my Debian 4.0 machine. A fact which makes requiring certain code to raise a signal problematic.Requirements:· You'll need a c or c++ compiler with a working preprocessor (if objective c or the like works for you, let me know!) · You must be able to link the code you're testing with c or c++, and you can only test object files which do not define main() · GNU makeWhat's New in This Release:· This version adds an optional, simple-minded locking mechanism based on POSIX semaphores.
