Abstract: Testing the product just before its release to the customer is very important as it marks the success of that product. In software development, testing of the software is conducted at the last stage of the development cycle. During software testing, there will a large number of variables and their possible values. For this if conventional testing process becomes cumbersome and hence a more efficient testing strategy has to be applied. This paper discusses the application of Orthogonal Array based Software Testing (OATS) for minimizing the number of bugs in the software. In this paper, Taguchi’s Orthogonal Array (OA) is applied for compatibility testing of a website, by considering five control factors and one interaction between the factors. Experiments have been conducted using L18 orthogonal array; experimental results are analyzed using Smaller-The-Better (STB) type of Signal-toNoise (S/N) ratio and optimal levels for the control factors are obtained. With these optimal levels it is found that the number of bugs has been considerably reduced.
