Abstract

This report presents a survey on quality assurance of Web applications. Starting from the introduction of Web application architecture, it discusses the quality factors of Web applications. First, the basic software measurement concepts are introduced. A quality model specifies which properties are important to a Web application and how these properties are to be determined. Based on the specification of the entity type, the attribute definition, metric formula, and application procedures, a catalog of metrics can be used to support different quality assurance processes. Quality control and assurance are widely applied in today's Web-based system development processes. User-centered quality engineering is introduced in the context of Web application development processes, which results in increasing of software quality and end-user satisfaction. Tools and measurement methods are developed and applied in the Web applications quality assessment procedures--SUMI is a method to evaluate the software system usability and a Web-centered Function Points measure gives the estimation of the maintenance cost of Web system.
