DEPRECATION WARNING: request methods will accept only keyword arguments in future Rails versions.

DEPRECATION WARNING: ActionController::TestCase HTTP request methods will accept only
keyword arguments in future Rails versions.

examples:

get :show, params: { id: 1 }, session: { user_id: 1 }
process :update, method: :post, params: { id: 1 }

I'm using Rails 5 alpha.
Instead of:

post :create, my_model: { some_attribute: 'some attribute' }

Rails 5 will accept only:

post :create, params: { my_model: { some_attribute: 'some attribute' } }

Warning called from:

shoulda-matchers-3.0.1/lib/shoulda/matchers/action_controller/permit_matcher.rb:250)

My spec:

it "permit only whitelisted params" do
    params = { my_model: valid_attributes }

    is_expected.to permit(
        :name, 
        :release_date, 
        :description
    ).for(:create, params: params).on(:my_model)
end

My "solution" for now is
change:

.for(:create, params:  params )

to:

.for(:create, params:  { params: params } )

Okay! Thanks for the report. I've got a backlog right now of stuff to work through right now, but hopefully I can get to this before Rails 5 ships. PR appreciated. :)

So I don't need to make any changes to my RSpec, I can wait for the patch and it will fix all these deprecation warnings and save myself a bunch of trouble?

[mcmire]

If you're still using Rails 4, yeah -- I know the warnings are annoying, but it's okay for right now. If you're using Rails 5 then there isn't a fix for this yet, unfortunately.

[JeremyEllingham]

No worries. Is there going to be eventually? I'll keep an eye on this and leave it be if it will be fixed eventually, it's not actually causing a failed case yet.

[mcmire]

This will be fixed by #964, so I'm going to go ahead and close this to clean things up.
