Test Case Design Using Classification Trees
نویسنده
چکیده
The systematic test is an inevitable part of the verification and validation process for software. The most important prerequisite for a thorough software test is the design of relevant test cases, since they determine the kind and scope and hence the quality of the test. The classification-tree method and the graphical editor CTE (classification-tree editor) support the systematic design of black-box test cases. The classification-tree method is an approach to partition testing which uses a descriptive tree-like notation and which is especially suited for automation. Method and tool have already been tried out successfully on actual examples in various divisions of the Daimler-Benz Group. Three steps were found to be most important in the test case design for real-world applications: (1) Selecting test objects, (2) Designing a classification tree and (3) Combining classes to form test cases. In this paper a strategy to accomplish these steps systematically is outlined.

Graph Transformations for Model-based Testing
Model-based development uses modeling and simulation as essential means for specification, rapid prototyping, design, and realization of embedded systems. The classification-tree method complements model-based development with a formal approach for test case description and automation. This paper shows how “raw” classification trees are transformed into complete classification trees using an ex...

متن کاملUsing Machine Learning, Neural Networks, and Statistics to Predict Corporate Bankruptcy
Recent literature strongly suggests that machine learning approaches to classification outperform “classical” statistical methods. We make a comparison between the performance of linear discriminant analysis, classification trees, and neural networks in predicting corporate bankruptcy. Linear discriminant analysis represents the “classical” statistical approach to classification, whereas classi...
