Question

I have in User.rb model:

before_save { self.email.downcase! }

and I need to stub this method in users_controller_spec.rb:

User.any_instance.stubs(:before_save_callback_method).returns(true) #doesn't work
User.any_instance.stubs(:valid?).returns(true) #works

How can I do this?

Answer 1

You don’t really need to stub out the before_save callback, rather you can stub out methods called by the callback. You can move the behavior to a method and stub that instead.

before_save :downcase_email

def downcase_email
  self.email.downcase!
end

Then in your specs:

user.stub(:downcase_email).and_return(true)
