question: public void testStepByOne ( ) { final Range range = createRange ( 1 , 5 ) ; final List result = range . step ( 1 ) ; assertEquals ( "wrong number of calls" , 5 , result . size ( ) ) ; final Iterator iter = result . iterator ( ) ; for ( int i = 1 ; i <= 5 ; i ++ ) { assertEquals ( "incorrect value in result" , createValue ( i ) , iter . next ( ) ) ; } }
target:  Tests stepping through a range by one.
