Classification-Hierarchy Table: a methodology for constructing the classification tree

Abstract

The Classification-Tree Method developed by Grochtmann and Grimm (1993) provides a systematic approach to produce test cases based on the functional specification. This paper supplements the Classification-Tree Method by proposing a methodology to construct a classification-tree from a given set of classifications and classes based on the notion of Classification-Hierarchy Table. The Classification-Hierarchy Table is used to capture the hierarchy of a classification tree. From this table, useful information such as the relative level of the classifications in the tree, their parent classifications and parent classes could be obtained to guide the construction of the classification tree.
