質問 2：
You work for a company who are pioneers in smart energy technology. One of their core products is their energy monitor in-home display device, used to display current and historic energy consumption data to many thousands of customers. It has been designed to integrate with their other smart home products, including domestic lighting control systems via their HomeHub.
The energy monitor in-home display device has been designed to interact with the home's lighting system and automatically dim bedroom lights when the daily energy budget has reached 90%. A defect has been found in the energy monitor's software which causes lights to be dimmed at 80% of the daily budget. What type of testing would MOST likely have uncovered this defect?
A. Functional appropriateness testing.
B. Adaptability testing.
C. Interoperability testing.
D. Accessibility testing.
正解：A

質問 3：
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 Kens overall objectives.
Which of the following represents the best choice of testing techniques in this scenario?
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 4：
A web-based system is being developed to support the administration of tennis tournaments.
The system provides advice on how much money to offer each player as their individual attendance fee. The amount depends on a COMBINATION of the following factors:
Overall attendance fund (divided into five numeric ranges).
Player's current world ranking (divided into ten numeric ranges (i.e. top 10, top 20, top 30, other).
Whether it is a local tournament for the player (i.e. YES or NO)
Their relationship with the tournament sponsors (i.e. clothing, equipment, or endorsement).
Their previous attendance history at this event (i.e. finalist, played, withdrew before event or withdrew during event) It has been noted that the attendance fee calculation does not take account of 'last minute' invitations that are made to replace a player who withdraws close to the tournament start date. In this case enhanced attendance fees are offered depending on whether the invitation is made within a week, a fortnight, or a month of the tournament start date.
Which of the following specification-based techniques would be the BEST choice for testing that the appropriate fees are calculated for the 'last minute' scenario, and what type of defect is being targeted by the testing?
A. Use Case testing technique; Fee specification defects
B. Equivalence Partitioning technique; Date formatting defects.
C. Decision Table testing technique; Fee calculation defects.
D. Boundary Value Analysis technique, Date comparison defects.
正解：C

質問 5：
A major upgrade of business software has been undertaken, with many new facilities added in response to the wishes of the (internal company) staff. There are now very different screens presented to users, depending on their roles within the business.

Which of the following quality characteristics would you focus on the MOST when testing the system?
A. Functional appropriateness.
B. Installability.
C. Functional correctness.
D. Functional completeness.
正解：C

質問 6：

You may assume all actions are different and independent.
A. 12
B. 8
C. 102
D. 6
正解：D

質問 7：

A. Make sure the scribe logs issues at a rate of 1 issue per minute
B. Ask moderators to cut back on discussion in the logging meeting
C. Ask checkers to try a checking rate of 6 pages per hour
D. Ask checkers to try a checking rate of 4 pages per hour
正解：D

質問 9：
Which pair of statements correctly describes when functional completeness, functional correctness and/or functional appropriateness are undertaken?
A. Functional completeness for system integration may focus on high level business cases; functional appropriateness is usually performed prior to system testing.
B. Functional appropriateness testing is usually undertaken during system testing (but also during the later stages of integration testing); functional correctness testing can be conducted at any test level.
C. Functional correctness testing is only performed at the system test level; functional completeness is performed at the system integration testing stage.
D. Functional completeness is performed as the last stage of testing; Functional correctness can be undertaken at any test level and often uses the specification or legacy system as a test oracle.
