Question 2

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?

B : Pairwise Testing with orthogonal arrays

C : State Transition Testing using 1-switch coverage

D : Classification Tree Method

Answer: C

Question 3

You are testing the processing of a critical traffic control system to which various regulations apply. The processing of the input variables is dependent of defined ranges within which the actual retrieved data values can lie.

Which of the following test techniques will you use to the processing functionality of the traffic control system?

[K4] 3 credits

Options :

A : defect taxonomies

B : exploratory testing

C : equivalence partitioning enhanced with boundary value analysis

Answer: C

Question 4

Supercar is an online vehicle sales website specializing in a single manufacturer's Sports Utility Vehicles (SUVs) and saloons. A vehicle has two key elements, power unit and body style. The manufacturer offers three choices of power unit: petrol, diesel and hybrid. There are 3 main body styles:

Saloon, Hatchback and SUV. SUVs only come as petrol and diesel options. Hybrid is available for Hatchback only. The site will allow an order to be processed if at least one of the chosen vehicle configuration is in stock, otherwise a message will be displayed asking the user to try again later.

As a tester you are asked to review the ''Supercar'' specification before starting to design the corresponding test cases.

Which of the comments below would you make?

[K3] 2 credits

Options :

A : I have no comments, specification looks ok

B :

Boundaries for stock levels are ambiguous

C : Dependencies power unit and body styles are ambiguous

D : It is not clear which message will be displayed when ''out of stock''

Answer: D

Question 5

stakeholders?

[K2] 1 credit

Options :

B : They should be able to use them as a basis for designing test cases

C :

They should be able to use them to establish traceability to requirements

D : Test documentation should always be understandable by all stakeholders
