Test Analysis and Test Design

How many invalid test cases can be identified from the provided “Route Calculation” state table?

You may assume that all actions are distinct and independent.

Explanation

An invalid state-transition test exercises an action that is not permitted in the current state. The Route Calculation state table has six undefined state/action combinations; because the actions are distinct and independent, each combination requires its own invalid test case.
