A Graphical Class Representation for Integrated Black- and White-Box Testing
نویسندگان
چکیده
Although both blackand white-box testing have the same objective, namely detecting faults in a program, they are often conducted separately. In our opinion, the reason is the lack of techniques and tools integrating both strategies, although an integration can substantially decrease testing costs. Specifically, an integrated technique can generate a reduced test suite, as single test cases can cover both specification and implementation at the same time. This paper proposes a new graphical representation of classes, which can be used for integrated class-level blackand white-box testing. Its distinguishing feature from existing representations is that each method of a class is shown from two perspectives, namely the specification and implementation view. Both the specification of a method and its implementation are represented as control flow graphs, which allows blackand white-box testing by structural techniques. Moreover, a test suite reduction technique has been developed for adjusting white-box test cases to blackbox testing.

متن کاملIntegrating White- and Black-Box Techniques for Class-Level Regression Testing
In recent years, several techniques have been proposed for class-level regression testing. Most of these techniques focus either on whiteor black-box testing, although an integrated approach can have several benefits. As similar tasks have to be carried out for both whiteand black-box testing, an integrated approach can improve efficiency and cost effectiveness. This article explains a new appr...
متن کاملAn Integrated White+Black Box Approach for Designing and Tuning Stochastic Local Search
Stochastic Local Search (SLS) is a simple and effective paradigm for attacking a variety of Combinatorial (Optimization) Problems (COP). However, it is often non-trivial to get good results from an SLS; the designer of an SLS needs to undertake a laborious and ad-hoc algorithm tuning and re-design process for a particular COP. There are two general approaches. Black-box approach treats the SLS ...
متن کاملImproving the expressiveness of black-box models for predicting student performance
Early prediction systems of student performance can be very useful to guide student learning. For a prediction model to be really useful as an effective aid for learning, it must provide tools to adequately interpret progress, to detect trends and behaviour patterns and to identify the causes of learning problems. White-box and black-box techniques have been described in literature to implement...
متن کاملAn Integrated Testing Technique for Component-Based Software
The main idea of component-based development is to use existing components for building software. The resulting software often has features which complicate testing, such a feature is, for example, the absence of component source code. This article proposes an approach for testing, which explicitly takes into account testing-relevant features of component-based software and thus allows more rig...
