RSpec控制器分页测试

Question

I'm adding some controller tests to make sure my pagination works correctly. I use the gemfile "Will-paginate", which automatically adds pagination at 30 users. In this test I add 31 users and look for the selector but the error I'm getting tells me that the pagination never appears. What am I doing wrong?

Thanks guys!

HAML:

= will_paginate @users, :class => 'pagination'

user_controller_spec.rb

let(:user) { FactoryGirl.create(:user) }

describe 'GET #index' do
    before { get :index }

    it { should respond_with(200) }
    it { should render_template('index') }
    it { should render_with_layout('application') }
    it { should use_before_action(:authorize_user!) }

    it 'shows pagination' do
      users = FactoryGirl.create_list(:user, 31)
      expect(:index).to have_css('div.pagination')
    end
  end

Error:

1) Admin::UsersController GET #index shows pagination
 Failure/Error: expect(:index).to have_css('div.pagination')
   expected to find css "div.pagination" but there were no matches

The previous and now deleted answer had it right. You need to create the users before you do the get . The problem with both your question and the other answer is the use of let to create users, which lazily evaluates. Try it with let! for defining the users or by putting the creation of users inside a before , as in the following, which also uses subject to keep the setup separate from the code under test.

describe 'GET #index' do
    before { FactoryGirl.create(:user, 31) }

    subject { get :index }

    it { should respond_with(200) }
    it { should render_template('index') }
    it { should render_with_layout('application') }
    it { should use_before_action(:authorize_user!) }

    it 'shows pagination' do
      expect(:index).to have_css('div.pagination')
    end
  end
end
