           Summary: IndexedDB: keyrange methods should throw TypeError if
                    required arguments are missing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified

http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#idl-def-IDBKeyRange states that only(), lowerBound(), upperBound(), and bound() have required arguments. As per the WebIDL spec, calling these functions without the required arguments should throw a TypeError. This test calls these functions without arguments, or with too few arguments, and checks that they throw properly.

Expected behavior: throw TypeError
Actual behavior: does not throw, creates IDBKeyRange object

Patch included. The fix is to remove the LegacyDefaultOptionalArguments flag from the IDBKeyRange.idl. This will force the code generator to check for required arguments and throw TypeError if they are missing.
