I have started my journey with TDD in Rails and have run into a small issue regarding tests for model validations that I can't seem to find a solution to. Let's say I have a User model,
and a simple test
This correctly tests the presence validation, but what if I want to be more specific? For example, testing full_messages on the errors object..
My concern about the initial attempt (using should_not be_valid) is that RSpec won't produce a descriptive error message. It simply says "expected valid? to return false, got true." However, the second test example has a minor drawback: it uses the create method instead of the new method in order to get at the errors object.
I would like my tests to be more specific about what they're testing, but at the same time not have to touch a database.
Anyone have any input?
