Today I published an article to developerWorks that describes how our team was able to extend RFT to allow us to more consistently recognize the GUI objects in a Flex/Flash application. As you probably know RFT does come out of the box with Flex application automation support but it does not keep up with the constant browser and Flash plug-in updates. Even if you are not specifically testing Flex applications the article will help you see a hands-on example of how RFT can be extended, after all we tend to forget that RFT is a full fledged Eclipse IDE that can be molded into whatever kind of tool you need to solve various automation problems.See the article linked below:
How do you extend RFT?? I'd love to hear!!!
