A company wants to develop a web site to implement an on-line sales channel. The company has decided to do some usability testing, but resources are limited. The usability testing has therefore to be done as efficient as possible. Which THREE techniques would you recommend? [K4] 3 credits, 2 out of 3 correct 1 credit

• Heuristic evaluation

• Usability laboratory

• Exploratory testing

• Use case testing

• SUMI

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

• Percentage of participants who completed each task correctly

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

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

• SUMI user satisfaction score

A SUMI test was performed at an early stage within the system test. Hereafter you find the results of the SUMI test. Based on these results, what would you recommend as the most appropriate approach for usability testing? [K4] 3 credits

• Since the SUMI scores are largely above market average no further action on usability is needed

• Since the standard deviation of most SUMI scales is much too large, a new SUMI test must be performed

• Since the scores are not really showing a high level of user-satisfaction additional usability testing based on use case is needed

• Since the SUMI results do not provide details, an additional focused heuristic evaluation on the lower scales is recommended

During the test execution defects are found on non-compliancy to requirements, calculations that produce incorrect results, and improper handling of data or situations. Which of the following test types is most likely being performed? [K2] 1 credit

• Usability testing

• Interoperability testing

• Accuracy testing

• Suitability testing

Which of the following comments would be the MOST important one you would make? [K3] 2 credits

• Description of flow is not detailed enough

• Specific characteristics of actor(s) are missing

• No usability acceptance criteria

• User tasks not defined

You are 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. Which one of the findings described below is true regarding this requirement? [K3] 2 credits

• The requirement is ambiguous in terms of supported cards

• The paragraph indicates potential performance problems

• The paragraph is unclear in terms of advance limits

• The paragraph indicates potential usability problems

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

• I have no comments, specification looks ok

• Boundaries for stock levels are ambiguous

• Dependencies power unit and body styles are ambiguous

• It is not clear which message will be displayed when

As a tester you are asked to review the ATM use case provided below. The use case will be used as a basis for functionality testing to be performed later. Which one of the comments, described hereafter, would be the MOST important one you would make? [K3] 2 credits

• Acceptance criteria not defined

• Business priority is missing

• Post condition not defined

• Alternative flows are missing

You are starting to review some of the incident reports that have been submitted as a result of test execution. Which THREE of the comments would be your main findings when you have reviewed the following incident report? [K4] 3 credits, 2 out of 3 correct 1 credit

• Should have been two defect reports

• Ambiguous description

• Reproducibility is not indicated

• Defect type is missing

• Actual cause is missing

How does phase containment contribute to reducing the cost of development? [K2] 1 credit

• By eliminating defects as early as possible to minimize defect propagation

• By ensuring that the deliverables from any life cycle phase are tested only in that phase

• By using specific test techniques at each level and only at that level

• By concentrating the testing effort on the phases where failures occur
