Ext JS interacts with jQuery and Prototype. Microsoft Silverlight is a technology that is used in developing internet applications which can be thought similarly as Adobe Flash. Quality is one of the most critical factors which govern the business growth of any company. Software Testing is a fundamental technique that is used to guarantee the quality of the product by finding the bugs in the application. In this growing and competitive market timely delivery of a quality product plays an important role for an organization to be rated high. Therefore this makes the software testing a discipline and a time-consuming task as the applications are getting complex in nature day by day. Test automation gained importance in Industry as it can be used to avoid this situation and helps in improving the quality of the software at the expenditure of optimum cost and time demands continuous and systematic growth. The intent of this paper is to show how MVC with ExtJS has changed the patterns of web development. In this paper, we discuss MVC user interface, enhancements, performance, syntax and productive features which includes pre-built widgets, database migrations and tools for web APIs, asynchronous support and uniform responsive designs. A Test Automation Framework is a structure where several tools and concepts are made to work together to provide a platform for automating the testing process. The RESTful web services are also known as REST API is a Hybrid framework that incorporates both Keyword-Driven as well as the Data-Driven framework, which works like a plug and play template. This Hybrid framework provides a very fast way of creating test automation and also helps users who have less programming knowledge to perform automation easily.
