Run tests in ES3 #6
Description
Right now, we're only testing in phantomjs2 which is webkit's JavaScriptCore (ES5-6). But we have extensive feature detection and poly-filing for ES3 (around 20%) that is not tested.
saucelabs provides free testing capability for IE6-8 on WindowsXP. I have created an account but are in email correspondence with sourcelabs about the details of the test implementation.
This issue is just a public reminder to get it done.
