ISTQB Exam ATA Topic 6 Question 79 Discussion

Actual exam question for ISTQB's ATA exam

Question #: 79
Topic #: 6

For an ATM banking project introduced earlier, ''When the user first inserts a valid credit card type, the system considers the user to be in an unauthenticated state. When requesting a cash advance, the user must be in an authenticated state. The user authenticates by entering the proper PIN code. When authenticating the user, the system shall allow the user to enter their PIN code up to three times before failing the authentication and rejecting the card. On the first and second try, the system shall prompt the user to re-enter the PIN code.''

Suppose you are concerned that, depending on the exact number of invalid PIN codes entered, the system might behave improperly. Which of the following test design techniques is specifically targeted at such failures?

A) Equivalence Partitioning extended by boundary value analysis could also be useful, but it might not be as targeted as the state transition testing approach.

C) State Transition Testing using 1-switch coverage seems to be the most targeted technique for handling failures related to invalid PIN code entries.

B) Pairwise Testing with orthogonal arrays could be another option to consider for testing different combinations of inputs.

I'm not sure, but I think State Transition Testing using 1-switch coverage could also be relevant in this scenario.

I agree with Timothy. Equivalence Partitioning is a good technique to test different input values, including boundary cases.

Haha, I bet the PIN code is '1234' - the most common password ever. No wonder they need to limit the number of tries!

You know, they should just replace the PIN code with a fingerprint scanner. That would be much more secure and eliminate the whole 'three tries' issue.

I agree. It would make the authentication process smoother too.

That's a good point. A fingerprint scanner would definitely be more secure.

The correct answer is C) State Transition Testing using 1-switch coverage. This technique is specifically designed to test for failures in state transitions, which is exactly what we're concerned about in this ATM banking project.
