A 0-switch test case is a test case that covers one transition from one state to another. To achieve 100% 0-switch coverage, all the transitions in the state diagram must be tested. The state diagram has seven states: Login, Menu, Logout, Withdraw, Deposit, Get Balance, and Access Account. There are 13 transitions in the state diagram, as shown by the arrows. Therefore, 13 0-switch test cases are needed. References =

The smallest set of test conditions to provide minimum coverage of the boundary values is the one that tests the minimum and maximum values for each category of carpet installation prices, as well as the values that are just above or below the boundaries. Option A covers these values, as it tests the boundary values of 0, 20, and 40 square yards, as well as the values that are one square yard more or less than these boundaries. It also tests the maximum possible value for the carpet area and the value that exceeds it. The other options do not test all the boundary values or have redundant values. References =

Boundary value analysis is a technique that focuses on testing the values at the boundaries of valid and invalid partitions. It is suitable for testing the errors caused by incorrect use of relational operators in the code, such as “>” and “<” instead of “>=” and“<=”. By creating test cases using boundary value analysis, the tester can verify that the system handles the borderline cases correctly and does not miss any edge cases.

1-switch coverage means that every possible transition from one state to another is tested at least once. Option C is the only test case that covers the transition from 2nd try to eat card, which is not covered by any other option. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 58, section 4.3.2.2.

The correct answer isD.Functional appropriateness.

Functional appropriateness

Functional appropriateness is the type of testing that ensures the application is suitable for the intended purpose and the user’s needs. It evaluates the relevance, usefulness, and user-friendliness of the application’s functions and features. In this case, the application should be tested for its suitability for senior citizens, who may have different preferences, expectations, and abilities than younger users.The interface should be easy to understand, navigate, and operate, and the application should provide adequate help and feedback to the users1.
