| * Date: 22 Jan 2002 |
| * SUMMARY: Testing Error.prototype.toString() |
| * |
| * Revised: 25 Nov 2002 |
| * See http://bugzilla.mozilla.org/show_bug.cgi?id=181909 |
| * |
| * Note that ECMA-262 3rd Edition Final, Section 15.11.4.4 states that |
| * Error.prototype.toString() returns an implementation-dependent string. |
| * Therefore any testcase on this property is somewhat arbitrary. |
| * |
| * However, d-russo@ti.com pointed out that Rhino was returning this: |
| * |
| * js> err = new Error() |
| * undefined: undefined |
| * |
| * js> err = new Error("msg") |
| * undefined: msg |
| * |
| * |
| * We expect Rhino to return what SpiderMonkey currently does: |
| * |
| * js> err = new Error() |
| * Error |
| * |
| * js> err = new Error("msg") |
| * Error: msg |
| * |
| * |
| * i.e. we expect err.toString() === err.name if err.message is not defined; |
| * otherwise, we expect err.toString() === err.name + ': ' + err.message. |
| * |
| * See also ECMA 15.11.4.2, 15.11.4.3 |
