[K2] 1 credit

AIn a sequential V-model project the test analyst should start test analysis and design concurrently with coding

BIn Agile projects the test analyst should start test analysis and design concurrently with coding

CIn a sequential model project the test analyst should start test analysis and design concurrently with software design

Answer : D

Question 3

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?

[K4] 3 credits

AEquivalence Partitioning extended by boundary value analysis

BPairwise Testing with orthogonal arrays

CState Transition Testing using 1-switch coverage

DClassification Tree Method

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

AI have no comments, specification looks ok

BBoundaries for stock levels are ambiguous

CDependencies power unit and body styles are ambiguous

DIt is not clear which message will be displayed when ''out of stock''

Answer : D

Question 5

As part of defining an approach the usability, acceptance criteria need to be defined. Which of the following acceptance criteria would be appropriate for operability?

[K4] 3 credits

APercentage of participants who completed each task correctly

BMean extent to which each task was completely and correctly achieved, scored as a percentage

CMean time taken to complete each task (for correctly completed tasks)

DSUMI user satisfaction score
