1 This test creates a fragment containing three elements: "B", "U", and "P", attempts to appendChild this fragment and studies effects of mutation events on the fragment. 2 3 Inserting an element in front of the next item in fragment should not affect the result: PASS 4 Removing next item should not abort iteration: PASS 5 Appending an element at the end of the fragment should not affect the result: PASS 6 Continually re-appending removed element to the fragment should eventually throw NOT_FOUND_ERR: PASS 7 Moving next item to become previous sibling of the re-parentee should not result in stack exhaustion: PASS 8 9 This test creates a fragment containing three elements: "B", "U", and "P", attempts to insertBefore this fragment and studies effects of mutation events on the fragment. 10 11 Inserting an element in front of the next item in fragment should not affect the result: PASS 12 Removing next item should not abort iteration: PASS 13 Appending an element at the end of the fragment should not affect the result: PASS 14 Continually re-appending removed element to the fragment should eventually throw NOT_FOUND_ERR: PASS 15 Moving next item to become previous sibling of the re-parentee should not result in stack exhaustion: PASS 16 17 18
