Question

I have the following

it 'should assign a new profile to user' do
  get :new
  assigns(:user_profile).should ==(Profile.new)
end

But it’s not working. I’ve tried ‘eql?’ and ‘equal?’ respectively. How do I compare it in order to know if the contents of @user_profile is Profile.new?

I used to do a workaround doing a .class of the assigned variable, checking if it’s Profile but I want to stop with these bad practices.

Thanks.

The problem here is that Object.new invoked twice by design creates two different objects, which are not equal.

One thing you can do here is

let(:profile){ Profile.new }

it 'should assign a new profile to user' do
  Profile.should_receive(:new).and_return profile
  get :new
  assigns(:user_profile).should eq profile
end

Now you’re not actually creating a new profile when the controller action is invoked, but you are still testing that Profile is receiving new, and you’re testing that the return value of that method is being assigned by the controller to @user_profile.
