testing lists

for a method like this (given in modified TwoEndedLinkedList)
 
 public Object tail() {
       if (size() == 0) {
           throw new NoSuchElementException();
       }

       return tail.getItem();
   }

do we still have to test it for empty case?
and for the throwing excpetion case...we only need to test ONE method out of the whole class that throws an exception, correct? or do we need to force every method that throws an exception to throw an exception?

Holy crap, I can see this taking me forever tommorow. I've left all doc comments and testing for the whole day tommorow.

yah........I think we just test one that throws an exception.

When we force an error, and throw an exception, are we suppose to do the try~catch thing.....so catch the exception then print a prompt saying ERROR.....or something, ~OR~ are we suppose to just do nothing at all???just throw it???AHHHHHHH

[gabbie]

try the method
catch the exception
since exception is supposed to occur
you catch it
and do whatever you want..
as long as your method does that
it means you have forced a exception and your method works

Quick Q: do we need to test for private methods in the test classes? I don't remember ...  

[Yin]

nope..dun need to test private methods..
