• Question 15:

  Supercar Supercar is an online vehicle sales website specializing in 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 the chosen vehicle configurations are in stock, otherwise a message will be displayed asking the user to try again later. Based on the specification the following classification tree has been developed:

  

  Based on the "Supercar" classification tree the following positive test cases have been created:

• Question 19:

  As a test analyst you are involved in the early stages of an acceptance test for a Product Data Management system. You are asked to write test designs and test cases based on use cases. An early version of the system is also already available. It is a known fact that on the implementation level many things will change (including the user-interface). The tests will be carried by end-users with much domain knowledge who have also been involved in the project defining the user requirements and reviewing documentation. What is the BEST option regarding the level of detail and documentation required for test cases in the project? [K4] 3 credits

  A. Detailed concrete test cases since many re-runs of the tests are expected

  B. Logical test cases supported by concrete test cases to allow for traceability and enable future changes

  C. Concrete test cases only since the end-users have extensive domain knowledge

  D. Logical test cases only since the end-user have extensive domain knowledge and many changes are expected thus reducing testware maintenance effort

  Correct Answer: D

• Question 20:
