Most existing work on t-way testing has focused on 2-way (or pairwise) testing, which aims to detect faults caused by interactions between any two parameters. However, faults can also be caused by interactions involving more than two parameters. In this paper, we generalize an existing strategy, called In-Parameter-Order (IPO), from pairwise testing to(More)
SUMMARY This paper presents two strategies for multi-way testing (i.e. t-way testing with t>2). The first strategy generalizes an existing strategy, called in-parameter-order, from pairwise testing to multi-way testing. This strategy requires all multi-way combinations to be explicitly enumerated. When the number of multi-way combinations is large, however,(More)
Modeling the navigation structure of a dynamic web application is a challenging task because of the presence of dynamic pages. In particular, there are two problems to be dealt with: (1) the page explosion problem, i.e., the number of dynamic pages may be huge or even infinite; and (2) the request generation problem, i.e., many dynamic pages may not be(More)
Many software testing problems involve sequences of events. This paper applies combinatorial methods to testing problems that have n distinct events, where each event occurs exactly once. The methods described in this paper were motivated by testing needs for systems that may accept multiple communication or sensor connections and generate output to several(More)
Percutaneous pedicle screw fixation for lumbar posterolateral instrumented fusion is an attractive alternative to standard open techniques. The technical aspects of this procedure can be challenging and even frustrating when first learning the technique. However, once these techniques have been mastered, they offer a safe, less invasive, less traumatic,(More)
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 test sequence generation, where each test is an ordered sequence of events. Using a general labeled(More)
This paper describes the eight-day August 2013 test campaign designed to investigate and demonstrate viability of using classical magnetoplasmadynamics to obtain a propulsive momentum transfer via the quantum vacuum virtual plasma. This paper will not address the physics of the quantum vacuum plasma thruster, but instead will describe the test integration,(More)
