RSpec stub helper method in controller spec

Found similar questions but surprisingly none, that I've found, give a simple answer...

Trying to stub a helper method in my controller spec; not quite sure what object would need to be doubled?

Controller calls this method:

#app/helpers/sessions_helper.rb

def signed_in?
  current_user.present?
end

I'd like to stub it in spec to return true/false.

Solution

  • You can stub it from the controller spec:

    controller.stub!(:signed_in?).and_return(true) # emulate signed in user
controller.stub!(:signed_in?).and_return(false) # emulate unsigned user

    Object 'controller' is predefined in a controller specs.

    UPDATE:

    With RSpec 3 syntax:

    allow(controller).to receive(:signed_in?).and_return(true)
allow(controller).to receive(:signed_in?).and_return(false)

    Thanks to @jakeonrails for reminding.
