An Input Space Modeling Methodology for Combinatorial Testing

March 22, 2013
Author(s)
Mehra N. Borazjany, Laleh Ghandehari, Yu Lei, Raghu N. Kacker, D. Richard Kuhn
The input space of a system must be modeled before combinatorial testing can be applied to this system. The effectiveness of combinatorial testing to a large extent depends on the quality of the input space model. In this paper we introduce an input space

Applying Combinatorial Testing to the Siemens Suite

March 22, 2013
Author(s)
Laleh Ghandehari, Mehra N. Borazjany, Yu Lei, Raghu N. Kacker, D. Richard Kuhn
Combinatorial testing has attracted a lot of attention from both industry and academia. A number of reports suggest that combinatorial testing can be effective for practical applications. However, there still seems to lack systematic, controlled studies on

Combinatorial Coverage Measurement Concepts and Applications

March 22, 2013
Author(s)
David R. Kuhn, Itzel (. Dominquez Mendoza, Raghu N. Kacker, Yu Lei
Empirical data demonstrate the value of t-way coverage, but in some testing situations, it is not practical to use covering arrays. However any set of tests covers at least some proportion of t-way combinations. This paper describes a variety of measures

Protecting Wireless Local Area Networks

December 3, 2012
Author(s)
Shirley M. Radack, David R. Kuhn
This article summarizes the information that was presented in the February 2012 Information Technology Laboratory (ITL) bulletin, Guidelines for Securing Wireless Local Area Networks (WLANs). The bulletin, which was noted by WERB in February 2012, was

Combinatorial Coverage Measurement

October 26, 2012
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
Combinatorial testing applies factor covering arrays to test all t-way combinations of input or configuration state space. In some testing situations, it is not practical to use covering arrays, but any set of tests covers at least some portion of t-way

Efficient Algorithms for T-way Test Sequence Generation

October 16, 2012
Author(s)
Linbin Yu, Yu Lei, Raghu N. Kacker, D. Richard Kuhn, James F. Lawrence
Combinatorial testing has been shown to be a very effective testing strategy. Most work on combinatorial testing focuses on t-way test data generation, where each test is an unordered set of parameter values. In this paper, we study the problem of t-way

Measuring Combinatorial Coverage of System State-space for IV&V

September 13, 2012
Author(s)
David R. Kuhn, Raghu N. Kacker
This report describes some measures of combinatorial coverage that can be helpful in estimating this risk that we have applied to tests for spacecraft software but have general application to any combinatorial coverage problem. This method will be

Efficient Methods for Interoperability Testing Using Event Sequences

July 31, 2012
Author(s)
David R. Kuhn, James M. Higdon, J .M. Lawrence, Raghu N. Kacker, Yu Lei
Many software testing problems involve sequences of events. The methods described in this paper were motivated by testing needs of mission critical systems that may accept multiple communication or sensor inputs and generate output to several communication

Combinatorial Testing

June 25, 2012
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
Combinatorial testing is a method that can reduce cost and improve test effectiveness significantly for many applications. The key insight underlying this form of testing is that not every parameter contributes to every failure, and empirical data suggest

Evaluation of Fault Detection Effectiveness for Combinatorial and Exhaustive Selection of Discretized Test Inputs

June 4, 2012
Author(s)
Carmelo Montanez-Rivera, David R. Kuhn, Mary C. Brady, Richard M. Rivello, Jenise Reyes Rodriguez, Michael K. Powers
Testing components of web browsers and other graphical interface software can be extremely expensive because of the need for human review of screen appearance and interactive behavior. Combinatorial testing has been advocated as a method that provides

Combinatorial Methods for Event Sequence Testing

April 21, 2012
Author(s)
D. Richard Kuhn, James M. Higdon, James F. Lawrence, Raghu N. Kacker, Yu Lei
Many software testing problems involve sequences. This paper presents an application of combinatorial methods to testing problems for which it is important to test multiple configurations, but also to test the order in which events occur. For example, the

Combinatorial Testing of ACTS: A Case Study

April 21, 2012
Author(s)
Mehra N. Borazjany, Linbin Yu, Yu Lei, Raghu N. Kacker, D. Richard Kuhn
In this paper we present a case study of applying combinatorial testing to test a combinatorial test generation tool called ACTS. The purpose of this study is two-fold. First, we want to gain experience and insights about how to apply combinatorial testing
