Abstract
Covering arrays are being increasingly used as a tool to determine test cases for testing complex engineered systems. The primary appeal of using covering arrays for this purpose is that they are an efficient way to construct test cases that are effective at precipitating failures that are due to the combination of several inputs. However, when failures occur, determining the inputs that triggered the failures is usually a time consuming task. In this article we present a method that allows a test engineer to efficiently analyze the outcomes of a set of test cases by making use of prior knowledge about the system under test. This analysis provides a ranking of input combinations that potentially triggered the failures.
