How testing associated objects?

Rails

please help solve the problem.

poll controller:

class PollsController < ApplicationController
def index
@user = User.find(params[:user_id])
@polls = @user.polls.paginate(page: params[:page], :per_page =>
10).order(title: :DESC)
end
end

route:

user_polls GET /users/:user_id/polls(.:format)
polls#index

polls_controller_spec.rb:
RSpec.describe PollsController, type: :controller do
describe “GET #index” do
before :all do
@user = FactoryGirl.create(:user)
end

it "assign user as @user" do
  get :index, user_id: @user.id
  expect(assigns(:user)).to eq(@user)
end


it "assigns polls as @polls" do
  get :index, user_id: @user.id
  expect(assigns(:polls)).to eq([@poll])
end


it "redirects to the index view" do
  get :index, user_id: @user.id
  expect(response).to render_template("index")
end

end
end

after run tests, i get follow error message:

I think you need to add a factory for polls, and ensure that you assign
a poll to that array before you test to see if there are any. Each test
runs alone, and not in a predictable order unless you’ve disabled the
test randomization feature in Rspec. Each test has a completely new and
fresh look at the application, with no preconceived data to work with
unless you provide it in your test, as you have done for the @user here.

Unless you accidentally removed it when posting here, you aren’t
creating
any Poll records. @poll is also not set to anything…

Being from India, this a question to Ruby on rails experts in India… i
have some doubts regarding risk based testing? how to perform it?
