RIA is built on Watir and Ruby. Watir itself can automate any web element where we can view the source of that element. Any proper HTML element that appears in the DOM can be interacted with by using Watir. RIA at this time will support any website that uses HTML elements as defined by the W3C and will support all Javascript as supported by Microsoft Internet Explorer 7.0 Javascript engine.

A complete list of elements supported by Watir can be located at here

Watir does not support the automating of plugin based components that are embedded in websites. The set of these plugin based components include Adobe Flash, Microsoft ActiveX, OpenLaszlo. These applications often do not affect the DOM and therefore IE has no way to discerning the type of element it needs to interact with. To Internet Explorer, these apps are simply a big black box. Their use is unconventional and not a standard approved by the W3C. Because these applications are black boxes, we have no way to testing it to ensure proper operation.

In addition, although Watir scripts support the use of conditions, branching, and loops, these constructs will not be supported by the Webmetrics RIA product.
