When a document management system is decommissioned, maintenance testing must include data migration testing to ensure that all documents are correctly transferred to a state archive, meeting legal requirements for long-term storage. This process verifies that data integrity is maintained during migration.

The statement that the shift-left approach can only be implemented with test automation is false. The shift-left approach emphasizes early testing activities in the software development lifecycle to detect and address defects as soon as possible. While test automation can support shift-left practices, it is not the only method. The shift-left approach can also involve practices such as static analysis, early requirement reviews, and integrating security vulnerability assessments early in the development process.

During release planning, a tester adds value by assessing the testability of user stories. This involves evaluating whether the user stories are clear, concise, and testable. The tester ensures that the acceptance criteria are well-defined and that the stories can be effectively tested within the given timeframe.

Equivalence partitioning involves dividing input data into partitions that are treated the same by the system under test. The given specifications create overlapping partitions:

For n < 0n < 0n < 0, an error message "Value out of range" is issued.

For 0 < n < 1000 < n < 1000 < n < 100, the factorial is calculated.

For 100 < n < 200100 < n < 200100 < n < 200, the same error message "Value out of range" is issued.

However, the range between 0 and 100 is exclusive of 0 and 100, meaning that the partitions overlap and create ambiguity for the boundary values. Thus, the correct statement is that the requirements are not correct because the partitions are overlapping​​.

Comprehensive and Detailed Explanation From Exact Extract:

“Acceptance testing focuses on validation and on demonstrating readiness for deployment… Ideally, acceptance testing should be performed by the intended users.”

(ISTQB CTFL Syllabus v4.0, Section 2.2.1 – Test Levels, Page 28)

Statements II and V are incorrect because:

Acceptance testing is not required to be performed by an independent team.

Acceptance tests are usually based on requirements or business needs , not component specifications.

A factor that contributes to a successful review is ensuring that all participants are trained to understand the review type and its objectives. This training helps participants to effectively contribute to the review process, identify issues, and suggest improvements. Proper training also fosters a constructive and collaborative review environment.

When deciding on the order of test execution based on priorities and dependencies, the correct sequence should consider both the priority levels and any dependencies between test cases. Here’s the analysis:

Test B has the highest priority (1) and depends on Test D .

Test D should be executed before Test B .

Test C has a medium priority (2) and depends on Test A .

Test A can be executed at any time since it has no dependencies.

Considering these dependencies and priorities, Test D should be executed first, followed by Test B . After that, Test A and finally Test C . Therefore, the correct sequence is D-B-A-C ​​.
