Consider the following pseudo code:
1 Begin
2 Read Time
3 If Time < 12 Then
4 Print(Time, "am")
5 Endif
6 If Time > 12 Then
7 Print(Time 12, "pm")
8 Endif
9 If Time = 12 Then
10 Print (Time, "noon")
11 Endif
12 End
How many test cases are needed to achieve 100 per cent decision coverage?
The three decisions are in sequence and the conditions are all mutually exclusive (if any one is true the others must be false). Hence a test case that makes the first decision true will make the second and third decisions false and so on.
So test case 1 (say Time = 6) would exercise the path True, False, False, test case 2 (say Time = 15) would exercise the path False, True, False. Test case 3 would have to be Time = 12. This combination achieves 100 per cent decision coverage because each decision has been exercised through its true and its false outcomes.
Which of the following statements are correct for walkthroughs?
(i) Often led by the author.
(ii) Documented and defined results.
(iii) All participants have defined roles.
(iv) Used to aid learning.
(v) Main purpose is to find defects.
Walkthroughs are often led by the author of the document and are used to aid learning and understanding among team members. These informal review meetings help in discussing the content and obtaining feedback from participants, but they are less formal than inspections and do not necessarily involve defined roles for all participants or result in documented outcomes. Reference: ISTQB CTFL Syllabus V4.0, Section 3.2.1.
When considering the roles of test leader and tester, which of the following tasks would NOT typically be performed by a tester?
Writing test summary reports is typically the responsibility of a test leader or manager, who consolidates testing activities and results to communicate with stakeholders. Testers are more involved in preparing and acquiring test data, setting up and checking the test environment, and reviewing tests developed by others. These tasks are more hands-on and technical, aligning with the role of a tester .

Which of the following statements best characterises maintenance testing? [K2]
Maintenance testing is conducted on the software after it has been delivered to address any issues or changes required due to defects, environment changes, or new requirements. The ISTQB syllabus explains that maintenance testing typically involves impact analysis to determine the extent of regression testing required, thus optimizing the testing effort and focusing on affected areas.
