38 * SUMMARY: Testing Error.length

39 * See http://bugzilla.mozilla.org/show_bug.cgi?id=123002

40 *

41 * NOTE: Error.length should equal the length of FormalParameterList of the

42 * Error constructor. This is currently 1 in Rhino, 3 in SpiderMonkey.

43 *

44 * The difference is due to http://bugzilla.mozilla.org/show_bug.cgi?id=50447.

45 * As a result of that bug, SpiderMonkey has extended ECMA to allow two new

46 * parameters to Error constructors:

47 *

48 * Rhino: new Error (message)

49 * SpiderMonkey: new Error (message, fileName, lineNumber)

50 *

51 * NOTE: since we have hard-coded the length expectations, this testcase will

52 * have to be changed if the Error FormalParameterList is ever changed again.

53 *

54 * To do this, just change the two LENGTH constants below -
