Automated Unit Testing of Embedded ARM Applications

Unit tests remove test complexity.

Unit testing isolates a single function from the set of all functions of the application and rigorously tests this function(or unit).

Rigorous means to comprise input data, that may be unexpected by the unit under test.

Isolation from the rest of the application can be achieved by direclty calling the unit under test and replacing the calls to other functions by stub functions.
