WebSys- Robustness Assessment and Testing

In recent years, the World Wide Web (WWW) has become a popular platform for system development. There are several factors that make Web-development special. There is a large number of quality requirements in the Web-based system. Web projects involve people with a diverse background, such as technical people with background in programming and non-technical people with background in graphical design. In addition, the Web-based system are often not developed separately, but is integrating existing subsystems. The time-to-marked requirement is strong. Web-based system must tolerate errors and abnormal situations caused by internal component failure or user mistakes. Therefore, robustness is considered to be a critical factor for Web-based systems. Building a robust Web-based system is never an easy task. Furthermore, the end users of Web-based systems have different backgounds. Many have knowledge of the Web, others have little or no knowledge of the Web. Since Web-systems are used by people with a rather diverse background, it is important that the Web-based systems must have error tolerance and ability to survive due to user mistake. The main focus of this project is analyzing robustness of Web-based system. In order to analyze robustness of Web-based system, it is necessary to carry out a robustness assessment. Assessment methods are used to evaluate the robustness and give an estimating of the system's robustness. Further, robustness testing of a Web-based system has to be performed to get an idea of the system's current robustness. The result of estimating and test result will also be discussed, compared and evaluated. An Automatic Acceptance Testing of Web Applications (AutAT) will be used to test the robustness of a Web-based system. DAIM (Norwegian: Digtal Arkivering og Innlevering av Masteroppgaver) is the target system that will be tested the robustness of.
