Correct Answers of earlier Q. 161 to 170 are at the end of this page:

Q. 171: You are testing a computerized gas pump that allows users to pay using credit cards. The pump is initially in the waiting-for-customer state. A transaction is initiated when a customer first inserts

a credit card. Four types of cards are accepted: Visa, MasterCard, Discover, and American Express. The pump will reject any other type of card. If given an accepted credit card, the pump validates the card. If the card is valid, the pump is turned on and the customer is told to begin pumping gas. The pump remains on until the transaction ends. The transaction ends when one of the following events occurs:# Pump handle is returned to pump

# Amount reaches transaction limit for card

# No gas is pumped within two minutes of validation of card

# The station attendant throws the emergency shut-off switch Once the transaction ends, the pump processes the transaction, charging the credit card and producing a receipt. It then returns to the waiting-for-customer state.

The following state transition diagram applies for the pump.

state transition diagram applies for the pump

Assume a test always starts and may only end in the waiting for-customer state, a test must end after a transaction-ending event, and a test input consists of (initial state, event[condition], next state, event[condition], …, event[condition], initial state). Design tests covering every unique sequence of up to four states/ three events. How many tests are needed for this level of coverage?

A. 2
B. 7
C. 14
D. 26

Q. 173: Your organization instituted requirements and design reviews for all projects 18 months ago. Reviews are still happening, are effective when they do occur, and data from the reviews is being used to locate other process improvement opportunities. However, you notice that only less critical projects manage to hold reviews for requirements and design documents. Ironically, the more business-critical projects are skipping some or all reviews and losing out on the schedule and quality benefits. Typically, as the schedule pressures build up on a project, fewer reviews are carried out, compounding schedule problems later when more bugs are discovered during system test.

Which of the following common causes of review failure is most likely at work in this scenario?

A. Insufficient training for the reviewers.
B. No continuous improvement from reviews.
C. Resistance by staff to the chosen review procedures.
D. Insufficient time scheduled for reviews in critical projects.

Q. 174: Suppose you are testing a banking system using real customer data. You are an employee of the bank and bound by complete confidentiality rules. Some of the bank’s customers are your neighbors. One of them lives in a very nice house. During a test, you discover that this neighbor is seeking bankruptcy protection. Which of the following statements is true?

A. You can tell anyone you’d like about this, as it’s a matter of public record.

B. You can tell your spouse about this but not your friends or other relatives.

C. You can’t tell anyone, but you can take advance steps to buy his house quickly if he defaults on his home loan.

D. You may not use or reveal that information for any purpose

Q. 175: Assume you want to test pairwise combinations of configuration options for a browser-based application. The application will support the following operating systems: Windows XP, Windows Vista, Linux, and Mac. The application will support the following browsers: Internet Explorer (latest version), Internet Explorer (previous version), Firefox (latest version), Firefox (previous version), and Opera (latest version only). The application must work at dial-up and broadband speeds.

Q. 176: You are testing a computerized gas pump that allows users to pay using credit cards. Four types of cards are accepted. Visa, Mastercard, Discover, and American Express. The pump will reject any other type of card. If given an accepted credit card, the pump validates the card. If the card is valid, the pump is turned on and the customer is told to begin pumping gas. The pump remains on until the transaction ends. The transaction ends when one of the following events occurs:

# Pump handle is returned to pump

# Amount reaches transaction limit for card

# No gas is pumped within two minutes of validation of card

# Emergency shut-off switch is thrown by the station attendant

Assume that a test is consists of a triple set of values, (card type, card validity, transaction ending). Design the minimum number of tests needed to cover all the equivalence partitions for each card brand, including both valid and invalid cards of each accepted type, along with covering each equivalence partition for transaction endings.

A. 4
B. 5
C. 9
D. 17
