ISTQB-CTAL-TA Exam Dumps : ISTQB Certified Tester Advanced Level - Test Analyst (CTAL-TACore)v3.1.2

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:

A (Use case testing):Not suitable as it focuses on user interactions rather than combinations of input values.

B (State Transition testing):Irrelevant since the focus is not on state changes.

C (Equivalence partitioning):Good for partitioning input values but not efficient for combinations.

D (Pairwise testing):Correct. This technique is highly efficient for coveringcombinations of multiple variableswith fewer test cases, which is crucial when the schedule is tight.

Therefore, the correct answer isD (Pairwise testing).

Comprehensive and Detailed in Depth Explanation:

InAgile projects, theTest Analyst’s involvementtypically startsat the beginning of the project.

Test Analysts workcollaboratively with developers, product owners, and other team membersfrom the outset to ensure thattesting is integrated into the development process.

Option A (Beginning of the first iteration)is too late since planning and discussing test approaches begin earlier.

Option B (After signing off user stories)contradicts the Agile principle of continuous involvement.

Option C (In parallel with coding)also occurs too late since testing considerations should start during planning.

The correct answer isD (At the beginning of the project).
