The software capability maturity model (SW-CMM) provides software organizations with guidance to how to gain control of their processes for developing and maintaining software and how to evolve toward a culture of software engineering and management excellence. Prof. J.N.Warfield has tried to identify and name each distinctive origin of one or more behaviorally related symptoms. Mindbugs (cognitive...
Code smells are poor implementation choices, thought to make object-oriented systems hard to maintain. In this study, we investigate if classes with code smells are more change-prone than classes without smells. Specifically, we test the general hypothesis: classes with code smells are not more change prone than other classes. We detect 29 code smells in 9 releases of Azureus and in 13 releases of...
Test coverage is a promising measure of test effectiveness and development organizations are interested in cost-effective levels of coverage that provide sufficient fault removal with contained testing effort. We have conducted a multiple-case study on two dissimilar industrial software projects to investigate if test coverage reflects test effectiveness and to find the relationship between test effort...
Comprehensive testing is necessary to ensure the quality of complex Web services that are loosely coupled, dynamic bound and integrated through standard protocols. Testing of such web services can be however very expensive due to the diversified user requirements and the large numbers of service combinations delivered by the open platform. Group testing was introduced in our previous research as a...
The problem of testing from an extended finite state machine (EFSM) can be expressed in terms of finding suitable paths through the EFSM and then deriving test data to follow the paths. A chosen path may be infeasible and so it is desirable to have methods that can direct the search for appropriate paths through the EFSM towards those that are likely to be feasible. However, generating feasible transition...
