What does maintainability in software testing focus on?

1. Finding defects that require reenactment

2. Automation of test processes

3. Effective defect resolution

4. Test case efficiency

The correct answer is: Finding defects that require reenactment

Maintainability in software testing primarily focuses on the ease with which software can be modified to correct defects, improve performance, or adapt to a changed environment. In this context, the option that aligns closely with the concept of maintainability is centered around the ability to find defects that require reenactment. This implies that maintainability encompasses not only the identification of defects but also the processes that allow those defects to be effectively addressed through reruns or re-execution of tests. When defects are found, it’s important that the testing framework and test cases can be easily modified or reused, which ensures that rerunning tests leads to effective results. If a defect requires reenactment, it suggests that the testing approach is conducive to easily addressing issues as they arise, which is a key aspect of maintainability. While other aspects like automation, defect resolution, and test case efficiency are important in their own right, they do not specifically capture the essence of maintainability which is about how seamlessly a system can adapt to changes or fix issues without excessive overhead.
