Based on the system state transition diagram of an ATM system shown below, using the state transition test technique which of the following is an example of a test case required to achieve 1-switch coverage?
The test case C is an example of a test case required to achieve 1-switch coverage, using the state transition test technique. A 1-switch test case is a test case that covers two states and the transition between them. To achieve 100% 1-switch coverage, all transitions between states must be covered by at least one test case. The test case C covers the transition from the state 1st try to the state 2nd try, and the transition from the state 2nd try to the state eat card.
