I agree with core developers, that there is no need for that to be implemented
inside JsTestDriver. Everybody has slightly different needs and this
would make configuration complicated.
It is easy to solve in JavaScript:
* request HTML page with XMLHttpRequest
* extract body
* inject into the body of the document under test
req = new XMLHttpRequest();
req.open('GET', url, false); /* synchronous */
req.send(null);
/* body element with children */
body_content = req.responseText.match(/<body[\s\S]*<\/body>/);
body = document.documentElement.getElementsByTagName('body')[0];
/* body tag itself is ignored, only its children will be inserted */
body.innerHTML = body_content;
}
