| * This file just picks one case where browsers are supposed to throw an |
| * exception, and tests the heck out of whether it meets the spec. In the |
| * future, all these checks should be in assert_throws(), but we don't want |
| * every browser failing every assert_throws() check until they fix every |
| * single bug in their exception-throwing. |
| * |
| * We don't go out of our way to test everything that's already tested by |
| * interfaces.html, like whether all constants are present on the object, but |
| * some things are duplicated. |
