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.
How does phase containment contribute to reducing the cost of development?

A.
By eliminating defects as early as possible to minimize defect propagation

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

C.
By using specific test techniques at each level and only at that level

D.
By concentrating the testing effort on the phases where failures occur
