42 * SUMMARY: Testing Error.length
43 * See http://bugzilla.mozilla.org/show_bug.cgi?id=123002
45 * NOTE: Error.length should equal the length of FormalParameterList of the
46 * Error constructor. This is currently 1 in Rhino, 3 in SpiderMonkey.
48 * The difference is due to http://bugzilla.mozilla.org/show_bug.cgi?id=50447.
49 * As a result of that bug, SpiderMonkey has extended ECMA to allow two new
50 * parameters to Error constructors:
52 * Rhino: new Error (message)
53 * SpiderMonkey: new Error (message, fileName, lineNumber)
55 * NOTE: since we have hard-coded the length expectations, this testcase will
56 * have to be changed if the Error FormalParameterList is ever changed again.
58 * To do this, just change the two LENGTH constants below -
