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?
