A PIN entry component of an ATM system has been developed using the following state table: Using the state transition test technique, how many 0-switch test cases are needed to achieve 100% 0-switch…

The correct answer is C. 8. A 0-switch test case is a test case that covers one transition from one state to another. To achieve 100% 0-switch coverage, all the transitions in the state table must be tested. There are eight transitions in the state table, as shown by the arrows. Therefore, eight 0-switch…

Explanation

A 0-switch test case is a test case that covers one transition from one state to another. To achieve 100% 0-switch coverage, all the transitions in the state table must be tested. There are eight transitions in the state table, as shown by the arrows. Therefore, eight 0-switch test cases are needed.
