At the moment we're evaluating Winrunner 8.2 to test our Powerbuilder (8.0) applications.
We'd like to know wat the experiences are using this combination of products, and how many users use these product in the Netherlands.
Powerbuilder w/ WinRunner is no more difficult than any other advertised WR compatible DE, depending on the versions of each. Can't speak from experience for your specific setup.
There is a Powerbuilder 8.0 Add-in for WinRunner 7.01 available from the Mercury support site.
I think you'll find that the Powerbuilder development universe is somewhat limited when compared to more recent and trendy tools.
