Embedded Unit is unit testing framework for Embedded C System. Its design was copied from JUnit and CUnit and more, and then adapted somewhat for Embedded C System.
Embedded Unit does not require std C libs.
All objects are allocated to const area.
These libraries did work on every system I tested so far - without problems: MacOS (ppc), Linux (ppc and x86), Windows (even Win98). Embunit is very simple - therefore easy to learn. If your focus is to run tests in a multi-process or multi-threaded environment, if you want to link test cases to requirements and update requirement test coverages in a database, if you want to measure code coverage - this tool might possibly be the wrong choice. Its simplicity is really brilliant! 1) Unpack the embunit package, 2) add the embunit paths to your include and linker paths, 3) copy and adapt a demo-test-case and you have your unit-tests running within only one hour.
