Leveraging Design Patterns and Design of Experiments for Testing Software

The inclusion of software design patterns in a thoughtful development process may be leveraged to expedite the testing process. Our results imply that the use of a testing strategy designed to access subsystem interfaces such as the facade pattern is a more efficient approach than statistical experimental design, one of the more traditional testing strategies. Statistical experiments are attractive if one is concerned with factor interactions but are more time-consuming to set up both in the selection of factors and levels and in the execution of repeated test cases
