I have been stuck on these test failures and have narrowed it down to the Order.calHandlingCharge() method. When I run and compile the program it works but I have these last 4 of 21 tests that fail in JUnit. Any thoughts? The error given is "caused an ERROR: java.lang.NullPointerException"
Any thoughts on what I can do to get it to pass the tests? I think that its not creating and instance of something that it needs for testing?
Good point they do not get created/instantiated or assigned a value by anything. I thought this was ok because I'm only comparing them to another null value, but maybe they are not a null value. I will assign them a value and compare to that value.
