Has anyone used PREVUE-X from Rational software?I'm evaluating whether to use the tool for testing of graphical user interface software.I would appreciate it if you could share any information regarding the advantages or disadvantages of using the
tool for testing GUI software.
Also, I would like to know whether it is a good tool for testing GUI software written using Java.I want a tool covering at least all Unix platforms (Solaris, HP, IBM, Linux).It would be good if the tool is independent of JDK version as our JDK version keeps changing. Also, I want a non-intrusive tool for black-box testing.

Please comment on PREVUE-X from RATIONAL with respect to the above points or let me know of any other tool meeting above criteria (if ny).Let me also know your experience with this tool and how you would compare it to XRunner from Mercury.

Thanks in advance.
