You are applying pairwise testing and using orthogonal arrays. The following steps are all part of the process to be followed.
i) Determine the number of choices for each variable ii) Map the test problem onto the orthogonal array iii) Construct the test cases iv) Identify the variables v) Locate an appropriate orthogonal array
What is the correct order of the above mentioned process steps?

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 TWO of the following items may more frequently need to be explained in greater detail for non-functional defect reports than for a functional defect report?

• C.Level of load on the system at the time of failure
• D.Actual results
• E.Expected results

For an ATM banking project introduced earlier, "When the user first inserts a valid credit card type, the system considers the user to be in an unauthenticated state. When requesting a cash advance, the user must be in an authenticated state. The user authenticates by entering the proper PIN code. When authenticating the user, the system shall allow the user to enter their PIN code up to three times before failing the authentication and rejecting the card. On the first and second try, the system shall prompt the user to re-enter the PIN code."
Suppose you are concerned that, depending on the exact number of invalid PIN codes entered, the system might behave improperly. Which of the following test design techniques is specifically targeted at such failures?
[K4] 3 credits

• A.Classification Tree Method
• B.Equivalence Partitioning extended by boundary value analysis
• C.State Transition Testing using 1-switch coverage
• D.Pairwise Testing with orthogonal arrays

While identifying scenario's for the use case "copy A4 - A4" for a new copier, the following scenario's were identified:
Basic scenario: single side to single side
Deviations: single side to double side, copy of a set, copy using the automatic document feeder
Failures: no paper in paper tray, paper jam, out of staples
How many test cases will be needed to achieve minimum coverage?
