Passes manual testing, but automated testing returns "NoSuchElementException: No Line Found" about forum HOT 3 CLOSED

When using the I/O method of testing, you should not create multiple scanners. Reason: all input text (given in one shot via the file) is swallowed by the first Scanner, leaving nothing for the subsequent scanners.

On a general note, the current code is tailored for a CLI interface where each command is stand-alone. Prompting for user input is hard to fit into the current code base, unless you put the code somewhere it doesn't belong, such as what you have done. :-p i.e. Interacting with the user should not be done in one place rather than all over the code base.
EDIT: should not be -> should not be

Oh yeah I tried to get the existing system to accept user inputs one by one, but found it too complicated to modify (hence the cheap hack with creating a new class to tack onto the existing 'add person' method).
