What do actual browsers do? The e-mail linked above is kind of cryptic.

The rest of the thread talks about that. From the thread, it sounds like other browsers currently throw an error.

Looks fine. The risk of compatibility problems seems small.

Way better to write these as one-liner tests:

    shouldBeNull('document.implementation.createHTMLDocument().querySelector("title")');
    shouldBeEqualToString('document.implementation.createHTMLDocument(null).querySelector("title").textContent', 'null');

That way the test output will show what we’re testing.

This doesn't seem to match http://dom.spec.whatwg.org/#dom-domimplementation-createhtmldocument. I'd expect leaving the argument out being the same as passing in undefined and passing the empty string to create an empty title element.

What am I missing?

Oh, nevermind. I misread. Doing too many things at once. :(
