The performance testing of Web applications is not understood properly and no skill sets are available to address the challenges faced by practitioners. In addition, there is currently a lack of available research on the performance aspects of the application. Integrated Approach to Web Performance Testing: A Practitioner's Guide fills this void and provides an integrated approach and guidelines to performance testing of Web-based systems. Based upon a mix of theoretical and practical concepts, this book provides a detailed understanding of the various aspects of performance testing in relation to the different phases of the software development life cycle. Using a rich mixture of examples, checklists, and templates, this book illustrates the different facets of application performance. Integrated Approach to Web Performance Testing: A Practitioner's Guide applies a practical approach to making appropriate choices of tools, methodologies and project management for performance testing.
