Identifying Failure-Inducing Combinations in a Combinatorial Test Set

A t-way combinatorial test set is designed to detect failures that are triggered by combinations involving no more than t parameters. Assume that the authors have executed a t-way test set and some tests have failed. A natural question to ask is: what combinations have caused these failures? Identifying such combinations can facilitate the debugging effort, e.g., by reducing the scope of the code that needs to be inspected. In this paper, they present an approach to identifying failure-inducing combinations, i.e., combinations that have caused some tests to fail. Given a t-way test set, their approach first identifies and ranks a set of suspicious combinations, which are candidates that are likely to be failure-inducing combinations.
