Scenario "Supercar"
Supercar is an online vehicle sales website specialising 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.

The development manager asks you to identify suitable test coverage entry criteria for the "Supercar" system test.
Which of the following would you recommend as appropriate for entry criteria to a system testing phase?
(i) 100% business requirements coverage
(ii) 100%statement coverage
(iii) 75% decision coverage
(iv) Availability of test release notes
(v) Design review completed

• A. (i), (ii), (iii)
• B. (i), (iv), (v)
• C. (ii), (iii), (iv)
• D. (i), (iv), (v)

If you are testing a set of signal changes at a railway station, which technique would you most likely use?

• A. Exploratory testing
• B. Boundary Value Analysis
• C. Pairwise testing
• D. State transition testing

Scenario "Tax system"
The tax system needs to be updated due to new legislation, For a person with a salary of less than f20.000 and who is married, the tax needs to be re-calculated. If the person also has more than two and less than five children, an additional 10% reduction is applicable.
How many input classes can be distinguished when applying equivalence partitioning to the Tax System specification?

• A. 5
• B. 7
• C. 8
• D. 6

Scenario "Banking Project"
As a test analyst in the banking domain you have received the following requirement:
"The system shall allow cash advances of at least 200 Euros for all supported credit cards, The correct list of credit cards is American Express, Diners, VISA, Mastercard and Eurocard. For the 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 PlN 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
• B. Pairwise Testing with orthogonal arrays
• C. Classification Tree Method
• D. State Transition Testing using 1-switch coverage

It is possible that the test execution phase will be shortened and that test cases will need to be prioritised.
What is the main reason to prioritise the test cases?

• A. Get finished within the time and budget available
• B. Ensure that when you stop you have done the best tests in the time available
• C. To ensure as many tests as possible are run
• D. Get the areas the programmer is most worried about finished first
