Web UI Testing - Cross Browser and Operating System

I've been looking at approaches for automating UI tests on our web applications. My question is:

Are there any tools out there that will allow me to replay UI tests in multiple browsers and multiple operating syste开发者_StackOverflow社区ms (in particular IE, FF, Chome and Safari on Windows and OSx)?

Thanks,

Mark

You can try: Selenium or Watir or iMacros

These allow you to either record a user journey (Selenium, IMacros) or to program in a user journey.

Watir comes in a number of flavours to fit your programming needs, ruby, dotnet, java, etc.
