* for the error's message.

* expect(fn).to.throw(err);
* expect(fn).to.not.throw(new RangeError('Out of range.'));
*
* Please note that when a throw expectation is negated, it will check each
* parameter independently, starting with error constructor type. The appropriate way
* to check for the existence of a type of error but for a message that does not match
* is to use `and`.
