Take the 2-minute tour ×  I am doing some regression testing
(changes to underlying database structures) where I'm lucky
enough to two separate environments which should contain the
same data. What I'd like to do is open a browser session in each
environment and then have one browser mirror the other (ie I
click on a control for example) so I can check the results
between browsers without having to repeat actions in each
browser. Does such a tool exist? Ideally the targetted browser
is IE.  share|improve this question add comment  4 Answers

tests built around Selenium WebDriver only open one browser
session and perform all operations on that session. However,
there's nothing stopping you from opening up two browser
sessions and performing the same operation in both sessions then
comparing the results like so...  //Begin test ie =
