Web Application Testing using Selenium and JUnitSoftware Testing The intent of Software Testing is to find the errors in a Software Applicationwhile it is being executed. These errors are called by different terminologies suchas errors, bugs, deviations or defects (Bertolino, 2007). A complete andcomprehensive testing strategy checks each and every requirement that the softwareapplication intends to satisfy. Both Verification and validation are two processesthat ensures that software meets the business requirements of the client as well as itworks exactly as it is expected to. Software systems are not error free. The reasons and chances of programerrors are plentiful. Thus companies around the world are spending a big portion oftheir resources to make the software systems robust, reliable, scalable, safe, secureand defect free. This is where the significance of an economical and decisivesoftware testing methodology becomes important. In spite of the best effort in thedesign, development and coding of software programs, some errors may persist inthe software after its completion. Ever increasing faults in the softwareapplications at various stages of development has invoked interest in SoftwareTesting. As a result, the importance of software testing as an integral part of thesoftware development process has been steadily growing and it has been regardedas the standard technique in the Software Industry to ensure quality and verify thecorrectness of the software.Formally, Software Testing is defined as “the process of exercising orevaluating a system or system component by manual or automated means to verifythat it satisfies specified requirements and actual results”. Software testing plays avital role in the software development process. Nearly one-third of the loss causeddue to software errors can be easily eliminated by an improved testinginfrastructure. A well designed testing process ensures that the software programperforms as per the requirement under all conditions. The process of testing asoftware system is a humongous task which is not only time consuming but alsovery costly. It was estimated that software testing and debugging alone consume3
