The objective in both cases is to determine which test cases exercise which methods in which components in order to enable selective regression testing..
.
This fact underscores the significance of selective regression testing, which has always been a major topic of software maintenance research.
.
.
This requires human intervention to extract test cases from the requirement documents.

.
This example shows that approaches like the clean room approach and black-box testing which work well enough in development do not work att all in maintenance. Since most maintenance work is done at the code level, the test must also be directed toward the code level. To make testing cost effective, there must be some way of relating test cases directly to code runctions.
