Tut is a unit test framework for c++, written in pure c++. it makes use of c++ templates to reduce the responsibilities of the user and provide an intuitive and easy-to-use interface. unlike other test unit frameworks for c++, tut doesn't use macros, since their usage conceals actual implementation and (what's worse) can interfere with client application.

tut completely fits into a single header file. no library compilation is required, thus a lot of portability problems are avoided and integration with client code is very simple.
