Automation testing has become more important because it is directly related to quality and productivity. A variety of web application testing tools has been developed, and each has its own set of apparent specifications, advantages, and limitations. It is necessary to have a thorough understanding of the operation, characteristics and limitations before implementing such testing tool, which leads to the desired benefit of automation. Objective of the work is to assess an open source automation testing tool and to provide a synthesized view to researchers and QA teams. Furthermore, to analyze and evaluate features and drawbacks of the tool, to make the process of adoption and implementation easy and accurate. Selenium is most popular, widely used and accepted tool in the industry. The work provides a complete analysis of Selenium’ straits and its impact in automated testing. Google Collaboratory has been utilized to illustrate Selenium's Python component. The results will be helpful to quality assurance teams, academicians and professionals in the direction of more insight in this region.
