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

Two cases are left when this decision table is collapsed. A decision table is a technique that shows the combinations of conditions and actions for a given scenario. A decision table that is collapsed eliminates the combinations that are invalid or impossible, such as having a scholarship without meeting the qualifications. The two valid cases for this scenario are:

C1 = Y, C2 = Y, C3 = Y, A1 = Y, A2 = Y

C1 = Y, C2 = Y, C3 = N, A1 = Y, A2 = N

The best black-box test technique to test the processing functionality of this system is equivalence partitioning enhanced with boundary value analysis. Equivalence partitioning is a technique that divides the input domain into subdomains that are expected to behave similarly. Boundary value analysis is a technique that tests the values at or near the boundaries of an input domain. These techniques are suitable for testing a system that depends on defined ranges of input variables, as they can ensure that all subdomains and boundary values are covered by test cases.

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).
