ISTQB Advanced Test Manager (ATM) — Question 8

The following are the exit criteria described in the test plan of a software product:
EX1. The test suite for the product must ensure that at least each quality risk item is covered by at least one test case (a quality risk item can be covered by more test cases).
EX2. All test cases in the test suite must be run during the execution phase.
EX3. Defects are classified into two categories: "C" (critical defect) and "NC" (non-critical defect). No known C defects shall exist in the product at the end of the test execution phase.
Which of the following information is useless when the specified exit criteria is evaluated?

Answer options

• A. A traceability matrix showing the relationships between the product risk items and the test cases
• B. A list of all the open defects with the associated classification information extracted from the defect tracking system
• C. A chart, showing the trend in the lag time from defect reporting to resolution, extracted from the defect tracking system
• D. The execution status of all the test cases extracted from the test management tool

Correct answer: C

Explanation

Option C is not useful for evaluating the exit criteria because it focuses on the speed of defect resolution rather than the existence of critical defects or the coverage of quality risks. In contrast, options A, B, and D provide essential information regarding test coverage, defect classification, and execution status, all of which are directly relevant to the exit criteria.
