/*
To get jquery tests to pass:
- add spaces between span>form selectors, other ones like one,two
- .last() instead of :last
- $("<div>").find("#foo") does not work unless the div is attached to the body.

- trigger .test not work
- No jquery.Event thing.

- jQuery.ajax() modifies incoming arguments?
- test framework not good for our io methods, async, poll.
- Dojo ajax is async: we fire ajaxStop more than jquery.

- jquery makes assumptions of a value to set for an element
by inserting an element and checking display. Does not seem to
account for nested styles, only captures generic tag name style off
of body. Why can't we just set display to empty?





OK for failures:
- test("jQuery.ajax - beforeSend, cancel request (#2688)"
  We cancel the deferred which triggers error and complete callbacks.


Looked at jquery code for:
- how it handled text(): did not use textContent/innerText, but use recursive look over childNodes and nodeValue,
so it may have impact on how <br> is serialized, but it has uniform behavior across browsers.
- Looked at trigger: how it triggered actions on dom nodes. This seemed unsafe.

/*
dojo.query differences that cause some tests to fail:
- does not support XML queries
- $("#sap>form") does not find a match but $("#sap > form") does. Similar issue with comma instead of > (see is() tests)
- "$("form:last") should return the last form object, not if that particular form is that last related
  to its siblings? Same issue with :first?
- $("p").filter("#ap, #sndp"): filter does not work.
- dojo.NodeList uses d.NodeList a few places in the code. Would be nice to use a ctor that can be configured.
  That would make the filter function operate better.
- filterQueryResult, cannot handle queries like "p, div"? See andSelf test with parents().
- adjacent "p + p" not supported?
= a:only-child not supported?
- nth(1)
- even/odd
- eq/gt/lt
- #form :radio:checked does not run the first :radio psuedo selector? Seems to be a general issue where only the last pseud
  is run. For example, "#form :checked:radio" does only the radio pseudo.
