Which of the following statements best characterises maintenance testing? [K2]
Correct Answer: A
The statement that best characterizes maintenance testing is A. Maintenance testing is triggered by changes to delivered software and uses impact analysis to minimize the amount of regression testing needed. Maintenance testing is a type of testing that is performed on a software product after it has been delivered to the customer or user, and aims to ensure that the software product still meets its requirements and expectations after any changes or modifications. Maintenance testing is triggered by changes to delivered software, such as bug fixes, enhancements, patches, updates, etc., and uses impact analysis to determine the scope and extent of regression testing needed. Impact analysis is a technique that analyzes the potential effects of changes on the existing software product and its components, dependencies, interfaces, etc., and identifies which parts of the software product need to be retested or modified. Impact analysis helps to minimize the amount of regression testing needed by focusing on the most affected or critical parts of the software product. A detailed explanation of maintenance testing can be found in [A Study Guide to the ISTQB Foundation Level 2018 Syllabus], pages 81-82.
