Tool-Supported Test Case Design for Black-Box Testing by Means of the Classification-Tree Editor

Abstract

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 graphical editor CTE (classification-tree editor) presented in this paper supports the systematic design of black-box test cases. The tool is based on the classification-tree method, an approach to partition testing which uses a descriptive tree-like notation and which is especially suited for automation. The tool has already been tried out successfully on actual examples in various divisions of the Daimler-Benz Group.
