A Virtualized Environment and Orthogonal Array as a Method for Software Testing

The combinatorial approach to software testing uses models, particularly an Orthogonal Array Testing Strategy (OATS) is proposed as a systematic, statistical way of testing pair-wise interactions to generate a minimal number of test inputs so that selected combinations of input values are covered. Because of these advantages, combinatorial testing methods are often applied in cases of the configuration testing. Good practice points to the simultaneous application of combinatorial testing and virtualization. Virtualization, in the process of testing, is based on setting the necessary environment to multiple virtual machines, which run on one or in smaller groups of physical computers, which are: reduce the cost of equipment and related resources, reduce the time required to manage the testing process, and favours raising removal of test infrastructure. Together, combinatorial testing and virtualization presents practical approach to improving process of testing, through the balancing quality, cost and time.
