ISTQB Exam CTAL-TTA Topic 6 Question 19 Discussion

In software testing, especially within contexts like nuclear power plants, achieving a 'highly recommended' level of coverage often requires strategic test case selection to verify all logical conditions are accurately assessed. For the condition 'If ((A > B) or (C > D)) and (E = F) then print A', the critical tests involve evaluating the boolean logic.

Test Case Analysis: Test Set 1 is selected because it should ideally include scenarios where:

Both conditions (A > B) and (C > D) are true, and (E = F) is true to ensure the print statement executes.

One of the conditions (A > B) or (C > D) is false while the other is true, combined with (E = F) being true, to test the OR logic.

Both conditions (A > B) and (C > D) are false with (E = F) being true, which should not trigger the print statement, testing the AND logic.

Condition where (E != F), irrespective of other conditions, to confirm that the print statement does not execute.
