質問 2：
Ken, an entrepreneur in Leeds finds the quality of the tea locally available so low, that he decides to research superior teas around the world. He decides to market, sell and distribute these superior teas via the web. His market strategy is to offer superior products on a well-designed website with graphics that are fast to load, has high availability, superior usability and fast response times.
The website will offer the following:
-An innovative interactive catalogue of teas, which not only enables customers to buy the product, but also enables them to provide feedback by rating the teas (which will influence his stock purchasing levels)
-
Provide the customer with the ability to use secure credit card transactions
-
Provide the customer to give general feedback
Ken selects an iterative model for the development of the prototypes. The team consists of three developers that are experienced in web development. Ken, although he doesn't have technical skillset, is concerned with quality. He doesn't believe a lot of documentation is necessary and he wants the website to be completed quickly.
The test basis contains the following:
-Story boards that show the information flow and page links through the site
-HTML pages developed to date.
-A statement of non-functional requirements.
With the strategy taking shape, Ken asks your advice on the specific testing techniques that should be used to complete the required testing, bearing in mind the nature of the application and the nature of Ken's overall objectives.
Which of the following represents the best choice of testing techniques in this scenario?
[K4] 3 credits
A. Exploratory testing to maximize the value of the team' experience
B. State transition testing to test the web site's availability statuses
C. Equivalence partitioning and boundary value analysis using the storyboard ideas as a basis to maximize functional coverage.
D. Decision testing to ensure that there is no redundant code
正解：A

質問 3：
You are working as a tester on a project to develop a point-of-sales system for grocery stores. Which of the following is a product risk that could be identified for such a system?
[K3] 2 credits

B. Failure to accept allowed credit cards
C. The arrival of a more reliable competing product on the market

質問 4：
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
A. Since the standard deviation of most SUMI scales is much too large, a new SUMI test must be performed
B. Since the scores are not really showing a high level of user-satisfaction additional usability testing based on use case is needed
C. Since the SUMI scores are largely above market average no further action on usability is needed
D. Since the SUMI results do not provide details, an additional focused heuristic evaluation on the lower scales is recommended
正解：D
