http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#widl-IDBObjectStore-get-IDBRequest-any-key states "This function produces the same result if a record with the given key doesn't exist as when a record exists, but has undefined as value. If you need to tell the two situations apart, you can use openCursor with the same key. This will return a cursor with undefined as value if a record exists, or no cursor if no such record exists." This test does exactly that. WebKit passes this test.
