Description

A start-to-finish methodology for testing object-oriented software: What, why, how, who, and when!

  • Understanding the unique challenges of testing object-oriented software.
  • Establishing test priorities, choosing approaches, developing test software, and more.
  • Includes a beginning-to-end case study.
While developers and IT organizations increasingly acknowledge the importance of software testing, few know how to proceed -- especially when it comes to testing advanced object-oriented software systems. In this book, two leading O-O test researchers and consultants outline a start-to-finish methodology for testing: what to test, why to test it, how to test it, who should do the testing, and when. The book is organized around a task orientation, encompassing testing models; testing components, systems and subsystems; and planning for testing. The authors review the unique challenges associated with object-oriented software testing, offer practical insights into testing priorities, introduce each leading testing technique, and walk step-by-step through applying them. They review the development of custom test software, and demonstrate how to strengthen the ties between testing and the rest of the development process. Features include a detailed object-oriented testing FAQ, and a running case study that ties together all stages and elements of O-O testing. For every IT manager, project manager, software developer and engineer, and for any professional concerned with the measurement of software quality.

John D. McGregor is an internationally recognized software testing consultant currently affiliated with Clemson University in South Carolina, where he leads a team of researchers investigating state-of-the-art object-oriented software test methods. David A. Sykes is an independent consultant specializing in object-oriented testing.
