Hallo Michael,
the usual question: which HtmlUnit version do you use?
HtmlUnit tries to emulate browsers but doesn't (yet ;-)) do it
perfectly. When such a problem is discovered, most of the time it can
quickly implemented.
Switching to Firefox emulation is done by specifying the User-Agent
header. Suggestions for a nicer way to handle it are welcome.
Cheers,
Marc.

Hello / Grüezi WebTest experts,
I am doing a <clickButton xpath="..."> on an HTML <button onclick="get(...)" where that get JS function calls some stuff which ultimately tries to do this:
// Automagically resize the layer to needed space.
function resizeLayer(theLayer){
theLayer=theLayer?theLayer:$("someframe");
if (document.all){ // IE
theLayer.style.width = theLayer.document.body.scrollWidth;
theLayer.style.width = theLayer.document.body.scrollWidth; //IE needs
doublecheck
theLayer.style.height = theLayer.document.body.scrollHeight+10;
}else{ // FF
theLayer.style.width = theLayer.contentDocument.body.scrollWidth+19;
theLayer.style.height = theLayer.contentDocument.body.scrollHeight;
}
}
which causes the following error:
Wrapped com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot read property
"body" from undefined (some.js#123) (...)
at submitForm(some.js:1638)
at get(some.js:1596)
at (onclick event for HtmlButton[<button class="iconbutton" title="submit"
onclick="get(...)">]:1)
where line 1638 is that "theLayer.style.width = theLayer.Document.body.scrollWidth;" from
above. If I understand this right, the theLayer thing probably works, but theLayer.Document is
undefined? I also tried the FF version (just by changing the some.js file) and it reports the
same error, just in the line "theLayer.style.width =
theLayer.contentDocument.body.scrollWidth+19", so again does this probably means the
contentDocument is not defined?
My question is: In principle, is this kind of thing supposed to work - like does HTMLUnit used by WebTest emulate a "full browser" where getting the Document from a layer should be fine - or am I already reaching the limits here?
Many thanks for any comments / ideas / etc. in advance!
PS: How/where can I "switch" to a "Firefox emulation" (does that exist?) so that there is
no document.all and it tries the else (without me changing the .js code). I noticed a log line "INFO
(com.canoo.webtest.engine.Configuration) - Surfing with browser 4.0 (compatible; MSIE 6.0; Windows 98)",
but that's just the Agent probably. Where to change that, and if it's change, will the document.all JS be
different?
