Abstract

Complete interaction testing of components is too costlyin all but the smallest systems. Yet component interactionsare likely to cause unexpected faults. Recently, design of experimenttechniques have been applied to software testingto guarantee a minimum coverage of all t-way interactionsacross components.However, t is always fixed.This paperexamines the need to vary the size of t in an individual testsuite and defines a new object, the variable strength coveringarray, that has this property.We present some computationalmethods to find variable strength arrays and provideinitial bounds for a group of these objects.
