Software Product Testing Using Orthogonal Array OA Testing Technique

Abstract This document describes the Orthogonal Array OA technique used in software testing. Orthogonal Array help in improving the Software product testing.Orthogonal Array employs design of experiments DOE which is one of the most important statistical tools of Total Quality Management TQM for designing high quality systems at reduced cost. Some of the benefits of Orthogonal Array techniques are the productivity improvement quality including high code coverage reduction in the test execution cycle time and enhanced customer satisfaction. The actual essence of testing lies in designing the minimal set of test cases which can uncover the maximum number of bugs in the system and at the same time gives a comfortable feeling about the quality of the system. Orthogonal Array Testing Strategy is a kind of Dream Come True for the test designers to design their test cases.
