ISTQB Updated ISTQB-CTAL-TA Exam Questions and Answers by jaiden

The checklist item that would result in finding a defect for the user story is “Are the acceptance criteria defined and testable?”. The acceptance criteria are the conditions that a system or component must satisfy in order to be accepted by a user, customer, or other authorized entity. The acceptance criteria should be defined and testable for each user story, as they provide the basis for designing and executing test cases. The user story in this question does not have any acceptance criteria defined, which is a defect that needs to be addressed.

Classification trees support the application of pairwise testing in the following ways:

a. They help to identify inputs to be used by the pairwise test technique - This is true because classification trees show the classes and subclasses of inputs for a given scenario in a graphical way.

b. They show the combinations needed to cover all-pairs - This is true because classification trees can be used to generate the combinations of inputs that cover all pairs using a mathematical algorithm.

c. They help to identify particular combinations of interest - This is true because classification trees can be used to highlight or prioritize certain combinations of inputs that are more relevant or important for the scenario.

d. They show both typical and atypical behavior - This is false because classification trees do not show the behavior or the expected results of the system under test, only the inputs and outputs.

e. They show the expected results for the various test cases - This is false because classification trees do not show the expected results or the verification criteria for the test cases, only the inputs and outputs.

The software quality characteristic that must be included in the test plan for this project is interoperability. Interoperability is a software quality characteristic that evaluates the degree to which two or more systems or components can exchange information and use the information that has been exchanged. This characteristic is relevant for a project that involves acquiring a COTS package that needs to interface with backend applications such as finance, stock control, and order delivery.

Comprehensive and Detailed in Depth Explanation:

A1-switch transitionin a state transition diagram is a direct move from one state to another without intermediate states.

FromScreen 1, the possible 1-switch transitions are:

Next:Moves toScreen 2

Back:Moves toMenu

Refresh:Stays onScreen 1

Sincerefreshcan be applied multiple times (loop), it is still considered as one transition.

Therefore, the number of 1-switch transitions fromScreen 1is3.

The correct answer isD (3).
