How Should I Throw?

I tried to write should.js style throw statements like so (new Bill(input)).should.throw(Error); but its not working. Where can I find resources wherein I can checkout documentation on should assertion style?

Try this…

(function () {
  new Bill(input);
}).should.throw(Error);

@sabrinaluo Try using .should.throw() and .should.not.throw() (with parenthesis).

You might also want to consider using throw Error('NOT A NUMBER') or even throw TypeError('NOT A NUMBER') in your class so that the stack is captured, though I don’t think this is directly related to your issue.
