| This is a testharness.js-based test. |
| FAIL Document.prepend() without any argument, on a Document having no child. parent.prepend is not a function |
| FAIL Document.prepend() with only one element as an argument, on a Document having no child. parent.prepend is not a function |
| FAIL Document.append() with only one element as an argument, on a Document having one child. assert_throws: function "function () { parent.prepend(y); }" threw object "TypeError: parent.prepend is not a function" that is not a DOMException HierarchyRequestError: property "code" is equal to undefined, expected 3 |
| FAIL Document.prepend() with text as an argument, on a Document having no child. assert_throws: function "function () { parent.prepend('text'); }" threw object "TypeError: parent.prepend is not a function" that is not a DOMException HierarchyRequestError: property "code" is equal to undefined, expected 3 |
| FAIL Document.prepend() with two elements as the argument, on a Document having no child. assert_throws: function "function () { parent.prepend(x, y); }" threw object "TypeError: parent.prepend is not a function" that is not a DOMException HierarchyRequestError: property "code" is equal to undefined, expected 3 |
| Harness: the test ran to completion. |
