Author should not validate without last name

[swt2public]

Scenario

When creating an author without last name Then validation should fail

Hints

Author data should only be added to the system if it reaches a certain quality. Especially, every author should have a last name, that is also not just an empty string. These checks are called 'validations' in Ruby on Rails.

For the tests, the be_valid matcher can be used to test if a model instance passes all validations: expect(@author).to_not be_valid

What do you think is the correct place to test this behavior, is it a model or a feature test?

You can learn about validations in this part of the guide.
