The equivalence partitions are based on the size of the carpet purchase and the installation price. There are four possible sizes: small, medium, large, and extra large. There are three possible prices: $5, $4, and $2 per square yard. The smallest set of test conditions that covers all the equivalence partitions is to test each size with its corresponding price, plus a no purchase scenario. Option C is the only one that does that. Option A does not test the large and extra large sizes. Option B does not test the extra large size. Option D tests more than the minimum required. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 50, section 4.1.2.2.

Pairwise testing is a technique that reduces the number of test cases by testing only pairs of values for each data item, instead of testing all possible combinations. Pairwise testing is based on the assumption that most defects are caused by interactions of at most two factors. Pairwise testing can be applied to this problem using the classification tree, which shows the data items and their values. By using pairwise testing, the number of test cases will be lower than exhaustive testing, which would require testing every combination of values for each data item. References =

Equivalence partitioning is a technique that divides the input domain into classes of data that are expected to behave similarly. The test sets should cover one value from each equivalence class, as well as the boundary values between them. The equivalence classes for the metro fare system are:

• Before 9:30 am (full fare)
• Between 9:30 am and 5:00 pm (saver ticket)
• Between 5:00 pm and 7:00 pm (full fare)
• After 7:00 pm (saver ticket)

The boundary values are 9:30 am, 5:00 pm, and 7:00 pm. Therefore, the test set that provides the best equivalence partitioning coverage is the one that includes one value from each equivalence class and the boundary values, which is option D. References =

The correct answer isA.Create test data for the keywords that includes error data and verifies the proper error is returned.

Create test data for the keywords that includes error data and verifies the proper error is returned

This is the best way to test the error conditions and still use the keyword-driven tests because it allows the reuse of the existing keywords and functions, while providing different inputs and expected outputs for the test cases.It also ensures that the error checking is automated and consistent, and that the test coverage is adequate1.

Testing pairs of combinations is a technique that reduces the number of test cases by testing only two factors at a time, instead of testing all possible combinations. Testing pairs of combinations is based on the assumption that most defects are caused by interactions of at most two factors. Testing pairs of combinations can be applied to this problem using the installation environments, which are the browsers, the operating systems, and the languages. By using testing pairs of combinations, the number of test cases will be lower than exhaustive testing, which would require testing every combination of factors. The formula for calculating the number of test cases for testing pairs of combinations is:

N = P * (P - 1) / 2

where N is the number of test cases, and P is the number of values for each factor. In this problem, P is 4, as there are four browsers, four operating systems, and four languages. Therefore, the number of test cases for testing pairs of combinations is:

N = 4 * (4 - 1) / 2 N = 4 * 3 / 2 N = 12 References =

The iterative model is a cyclical process in which the software product is developed and tested incrementally in short cycles called iterations. Each iteration delivers a working version of the product that can be evaluated and improved. Compared to the V-model, which is a linear and sequential process that follows a fixed set of phases and activities, the iterative model requires a reduced set of standard test processes for each iteration, as well as more flexibility and adaptability to changing requirements and feedback. The test analyst and the test team might expect to make this adjustment when working on an iterative model project. References =

Risk mitigation is the process of implementing actions to reduce the probability and/or impact of risks1. When you execute the tests in priority order based on the risk ratings, you are performing risk mitigation, as you are trying to prevent or minimize the potential failures and defects in the system2. Risk planning, identification, and assessment are the previous steps in the risk management process, which help to prepare for risk mitigation3.

The correct answer is C. All the expected environments and combinations.

All the expected environments and combinations

Interoperability testing should target all the expected environments and combinations that the system will interact with in the real world.This will ensure that the system can function correctly and reliably with different hardware, software, network, and external factors that may affect its communication and compatibility with other systems1.

State transition is a technique that analyzes the behavior of an application for different input conditions and how it changes from one state to another in response to events. It is useful for testing scenarios where the date of reservation is a critical factor that affects the system state and output1

The requirement states that the system shall allow cash advances of at least 200 Euros, but it does not specify the maximum amount or the conditions for different cards. This could lead to confusion, inconsistency, and errors in the system’s functionality and testing. The requirement should be more precise and define the exact limits and rules for each card type and scenario. References = ISTQBAdvanced Level Test Analyst Syllabus 2019, section 2.1.1; Requirement Analysis Templates & Techniques, section “Requirement Analysis Best Practices”.
