CUnit is a lightweight system for writing, administering, and running unit
tests in C. It provides C programmers a basic testing functionality with a
flexible variety of user interfaces.

CUnit is built as a static library which is linked with the user's testing
code. It uses a simple framework for building test structures, and provides a
rich set of assertions for testing common data types. In addition, several
different interfaces are provided for running tests and reporting results.
These interfaces currently include:

- Automated: Non-interactive output to xml file
- Basic: Non-interactive flexible programming interface
- Console: Interactive console interface (ansi C)
- Curses: Interactive graphical interface (Unix)
