Vidock: A Tool for Impact Analysis of Aspect Weaving on Test Cases

The addition of a cross-cutting concern in a program, through aspect weaving, has an impact on its existing behaviors. If test cases exist for the program, it is necessary to identify the subset of test cases that trigger the behavior impacted by the aspect. This subset serve to check that interactions between aspects and the base program do not introduce some unexpected behavior. Vidock performs a static analysis when aspects are compiled with a program to select the test cases impacted by the aspects. It leverages the pointcut descriptor to locate the set of methods impacted by aspects and then selects the test cases that can reach an impacted method. This static analysis has to perform overapproximations when the actual point where the aspect is executed can be computed only at runtime and when test cases call polymorphic objects. We measure the occurrence of these assumptions in 4986 projects containing 498 aspects to show they have a limited impact. Then, we run experiments with V...
