Utility for Mocking ResultSets

    //Create a Map that can be used as part of a result set
    //maxCount is the number of rows to be returned
    Map mockResultSet(int maxCount) {
        int count = 0;
	boolean closed = false;
        return [ 
            getCount : { -> count } ,
            next : { ->  count++ < maxCount }, //returns false after 
            close : { -> assertFalse(closed); closed = true; },
            isClosed : { return closed; }
        ];
    }

   ...

     Map pfIDsResultSet = mockResultSet(2);
     Closure pfIDsGetString =  { 
             String name 
            -> assertEquals("value", name);
            return "id"+pfIDsResultSet.getCount();
      }
     pfIDsResultSet.put('getString', pfIDsGetString);
