Abstract

Software testing is one of the most labor-intensive and crucial phases of the software development life cycle. It accounts for about 50–60% of the total cost of a project and requires a substantial amount of effort to ensure that the quality of the software is not compromised. Hence, optimizing the process of software testing has been of paramount importance in the IT industry. In recent times, there has been a significant shift toward software test automation to ensure the quality of the software while minimizing the cost and effort. This study proposes a statistical model analyzing the various factors that affect the testing cost, quality and effort by studying the behavioral pattern of professionals employed in the field of testing. The paper studies the factors, project duration, Software Complexity (SC), testing tools and automated test suite generation, while contrasting it with the overall software test automation, with the aim of finding a measure of how much automation affects the cost, quality and effort in practice. The results indicated that automation accounted for a variation of about 25% in each of the factors: cost, quality and effort much more than factors such as project duration, SC and testing tool . Further, the analysis indicated that the effect of SC on cost and effort was extremely low. This suggests that automation improved the quality while reducing the cost and effort irrespective of the complexity of the software being developed.
