/*
*
* 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
