My team has QTP scripts that we run against different configurations to confirm that our application works as expected.
One of the upcoming initiatives is to validate our product in IE9. I was happy to learn today that HP just released a patch
QTPWEB_00078) for testing web applications in Internet Explorer 9.
Patch QTPWEB_0078 includes support for working with Internet Explorer 9 on all operating systems that are supported by QuickTest Professional 11.
