HttpUnit and document.referrer
Another small patch to HttpUnit 1.6.1 to go along with my other one. The following JavaScript blows up in HttpUnit, but runs fine in a normal browser:
var temp = document.referrer;
if (temp.length <= 1) {
temp = "no referrer"
}
The resulting stack trace is below. The fix is to add the following method to the Document nested class in HttpUnit's JavaScript class.
public String jsGet_referrer() throws SAXException {
return "";
}
You could stub that method out with something more interesting, but that's good enough for me at this time.
