Test addEventListener() and removeEventListener() fail silently if arguments are missing.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


PASS new XMLHttpRequest().addEventListener("foo") is undefined
PASS new XMLHttpRequest().removeEventListener("bar") is undefined
PASS new XMLHttpRequest().addEventListener() is undefined
PASS new XMLHttpRequest().removeEventListener() is undefined
PASS successfullyParsed is true

TEST COMPLETE
