Dataflow testing of programs ensures the execution of data dependencies between locations in the code (1) where variables are assigned values, and (2) where these definitions are used. Such data dependencies are called Def-Use Associations (DUAs). In an aspect-oriented (AO) program, aspects and classes interact in several ways, such as (1) through parameters passed from advised methods in a class...
Test coverage is an important indicator for unit test quality. Tools such as Clover compute coverage by first instrumenting the code with logging functionality, and then logging which parts are executed during unit test runs. Since computation of test coverage is a dynamic analysis, it presupposes a working installation of the software. In the context of software quality assessment by an independent...
Testing aspect-oriented programs is challenging in part because of the interactions between the aspects and the base classes with which the aspects are woven. Coverage metrics, such as joinpoint coverage, address faults resulting from the changes in base class control flow that may be introduced by the woven advices. Definitions of joinpoint coverage in the literature typically require counting the...
Software reliability can be improved by using code coverage analysis to ensure that all statements are executed at least once during the testing process. When full code coverage information is obtained through software code instrumentation, high runtime performance overheads are incurred. Techniques that perform deferred or selective code instrumentation have shown success in reducing run-time overheads;...
