ISTQB ISTQB-CTAL-TA Exam With Confidence Using Practice Dumps

Eight cases are required to test the tax system specification using a decision table that is not collapsed. A decision table is a technique that shows the combinations of conditions and actions for a given scenario. A decision table that is not collapsed contains all possible combinations of conditions and actions, regardless of whether they are valid or not. The conditions for this scenario are:

Salary less than €20 000

Married

Number of children more than two and less than five

The number of cases is equal to the number of possible combinations of these conditions, which is 2^3 = 8. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.3.1, page 37.

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).

The most important information that is missing from this use case is the alternative behaviour, which describes the exceptional or error flows of events that may occur during the execution of the use case. For example, the use case should specify what happens if the user enters an invalid PIN, if the ATM runs out of cash, if the user cancels the transaction, etc. The alternative behaviour is essential to test the robustness and reliability of the system under test.
