|
* 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
