Rails 5 deprecation warning for Controller tests

Rails 5 has changed its ActionController::TestCase::Behavior to methods we use in controller tests and now you need to specify params key to the requests.

So if you had this in you tests:

get :show, id: 1

You'll need to change to:

get :show, params: { id: 1 }

There is a warning message like this:

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 }

Even if you use Rpsec you will need to change because rspec-rails uses this module to create the requests to the controllers.
