2 Roadmap: - Introduction - Background and problem - Solution - Implementation - Discussion Copyrigh, 2005 © ACET

3 Example: The Collaborative P-Grade Grid Portal Copyright, 2005 © ACET

4 Definition Software TestingSoftware Testing –The purpose of software testing is the determination of error absence in software. An ideal test would therefore only succeed when software is free of errors. Usability TestingUsability Testing –Usability testing is a means for measuring how well people can use something… Copyright, 2005 © ACET

5 Problem Description Distributed Collaborative Software Development Copyright, 2005 © ACET TESTINGUSABILITY Limitation of automatic testing methods Distribution – Multiple locations of clients Test bed implementations often not realistic Collaboration – Multiple users working on one task Reconstruction of errors
