Model-Based Approach to Design web Application Testing Tool

摘要

Software engineering is a systematic approach defined as a science of industrial engineering that measures the practical methods and working process of the software engineers. This approach is based on analyzing, designing, assessment implementing testing and reengineering processes of given software All those phases are very important and have a specific role in SE's cycle, especially software testing that acts as a significant element in this cycle and it represents also a fundamental key for software quality assurance. Software testing has as goal to test the software performance by measuring the gap between the expected behavior of the software under test and the test results. This comparison allows the tester to analyze errors and bugs in order to fix them and develop the software performance. As a critical factor in SQA, software testing is considered like a definitive review of the tool's specification: it permits the tester to redesign the tool specification after the test in case of failure. This procedure is also applied on web applications, in similar ways to obtain the same goal: applications quality assurance, but the web applications are more complicated to be tested because of the interaction of the application with the rest of the distributed system. In fact, in more precisely terms, web application testing is a process that measures the functional and non functional proprieties of a given web application to analyze its performance in order to fix errors or even to reach a better level of the application under test. The demand on web applications or generally on software testing tools groups up with the increase in applications or software failures and cost.
