If a person has at least three and less than six children, an additional 10% reduction is applicable.
- A. Test set (ii)
- B. Test set (i)
- C. Test set (iv)
- D. Test set (iii)
Answer: B
Explanation:
Explanation
Test set (i) is the best option as it tests the boundary condition of a salary of less than €20,000 and being married, with a varying number of children including the boundary value of three children. This test set covers the minimum and maximum values for the salary and the number of children, as well as the nominal values.
The other test sets donot test the boundary value of the salary or the number of children fully, as they either omit or repeat some values. References =

NEW QUESTION # 23
As a Test Analyst on a project using the V-model lifecycle model, you have been working with expert business users for a program designed to assist car buyers in selecting options for new car models. The program has been in use for some time, and now your company has decided to implement some significant improvements, based on customer and sales representative's feedback.
You visit specific locations and gather information on how the product is currently being used, spend time with expert users, and walk through their envisioned scenarios.
Based on this information, what are you using for your test basis and what information is still missing?
- A. Use cases; the validation that the transactions are realistic
- B. State transitions; the starting and ending states
- C. State transitions; the events that cause the transitions between states
- D. Use cases; the exception and error handling behaviors
Answer: A
Explanation:
Explanation
Use cases are a test basis that describe the interactions between the users and the system in terms of scenarios.
Use cases capture the functional requirements and the expected outcomes of the system. By visiting locations, spending time with expertusers, and walking through their scenarios, the test analyst is using use cases as the test basis. However, use cases do not provide enough information to validate that the transactions are realistic, such as the prices, discounts, taxes, and fees involved in the car buying process. This information is still missing and needs to be obtained from other sources, such as the business rules or the data model. References

You are testing the processing of a critical traffic control system to which various regulations apply The processing of the input variables is dependent on defined ranges within which the actual retrieved data values can lie.
Which of the following black-box test techniques should you use to test the processing functionality of this system?
- A. Pairwise testing
- B. State transition testing
- C. Use case testing
- D. Equivalence partitioning enhanced with boundary value analysis
Answer: D
Explanation:
Explanation
Equivalence partitioning is a black-box test technique that divides the input domain of a system into partitions of equivalent data. Boundary value analysis is a technique that tests the boundaries of these partitions, where errors are more likely to occur. These techniques are suitable for testing the processing functionality of a critical traffic control system, as they can ensure that the system handles the input variables within the defined ranges and detects any invalid or out-of-range values.

NEW QUESTION # 27
Supercar is an online vehicle sales website specialising in a 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 mam 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 at least one of the chosen vehicle configurations is in stock, otherwise a message will be displayed asking the user to try again later As a Test Analyst you are asked to review the Supercar specification before starting to design the corresponding usability test cases. Which of the comments below should you make?
- A. Dependencies between power unit and body style are ambiguous
- B. I have no comments, specification looks OK
- C. Boundaries for stock levels are ambiguous.
- D. It is not clear which message will be displayed when the car is "out of stock"
Answer: A
Explanation:
Explanation
The specification does not clearly define the dependencies between the power unit and the body style options.
For example, it is not clear if the user can select a hybrid power unit and then choose a saloon body style, or if the hybrid option is only available after selecting a hatchback body style. Similarly, it is not clear if the user can select an SUV body style and then choose a hybrid power unit, or if the SUV option is only available with petrol or diesel power units. These dependencies affect the usability of the site, as they may confuse the user or limit their choices. The specification should specify the valid combinations of power unit and body style, and how the site will handle invalid or unavailable combinations.

NEW QUESTION # 28
While experience-based testing can be very effective, it does have some drawbacks. What is a drawback of experience-based testing?
- A. It can be time-consuming and create a large amount of test documentation
- B. It requires an extensive amount of pre-planning by experienced testers
- C. It is difficult to achieve specific test coverage levels
- D. It is too structured for some test situations
Answer: C
Explanation:
Explanation
Experience-based testing is a technique that relies on the tester's intuition, skills, and past experiences to create test scenarios. However, this approach makes it challenging to measure and assess the test coverage, as there is no clear criteria or method to determine which areas of the software have been tested and which have not. This can lead to gaps in the testing process and potential risks of missing defects1 References =

Ken finds the quality of the tea locally available to be 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 marketing strategy is to offer superior products on a well-designed website that has fast loading graphics, 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 with the ability to give general feedback.
Ken selects an iterative model for the development of the prototypes. The team consists of three developers who are experienced in web development Ken, although he doesn't have a 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 set of non-functional requirements.
With the strategy taking shape, it is decided that exploratory testing should be used to complete the required testing, bearing in mind the nature of the application and the nature of Ken's overall objectives. You have now been given the task of identifying the exploratory tests, which will be executed as test sessions.
Which of the options below state what you will typically use for identifying the exploratory tests?
- A. Use external testers on the team to provide a new approach and fresh view to the testing effort
- B. Define low-level test cases to be executed by the end users.
- C. Apply equivalence partitioning and boundary value analysis using the storyboard ideas as a basis to maximise functional coverage
- D. Create test chatters to be used to guide the testing
