to test usability is to perform a list of tasks for the tester, define the optimal and most accurate path, track both time and amount of clicks spent on the achievment of that goal. It will be important also to track where users click or touch to define if there are any distracting or confusing elements within the interface. Test their confidence (rating). Finally, test the difficulty by asking the testers and compare results with the ones provided by other testers.
