Relenium has imported the java module Selenium (implemented in many languages, though) which has been traditionally used for web testing, via the package rJava. Its use is very intuitive, since reproduces the actions that a human would perform on a web page. The webpage of the project can be found here. There is an example explaining in detail how to use it. The package is still in development, so any comments/suggestions are welcome.
We hope you enjoy it.
