The book Quality Web Systems (Addison Wesley, August 2001) contains a Tool Evaluation appendix, comparing major tools from Mercury, Rational, Empirix, Compuware, Segue. This matrix will be useful for anyone curious about the capabilities of the various tools - it gives a general comparison overview, but it does not substitute for an in-house evaluation of the tool (see the Automated Software Testing book for the author's guidelines to help the test professional prevent uninformed decisions concerning the use of automated testing tools). This matrix (copyright Addison-Wesley) is provided courtesy of Addison-Wesley and Elfriede Dustin.
