This gem brings back assigns to your controller tests as well as assert_template to both controller and integration tests.

Note: This gem is only useful once assigns and assert_template have been removed from Rails.


Add this line to your application’s Gemfile:

gem 'rails-controller-testing'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails-controller-testing


See https://github.com/rspec/rspec-rails/issues/1393.

rspec-rails automatically integrates with this gem since version 3.5.0. Adding the gem to your Gemfile is sufficient.

If you use an older version of rspec-rails, you can manually include the modules in your rails_helper.

ruby RSpec.configure do |config| [:controller, :view, :request].each do |type| config.include ::Rails::Controller::Testing::TestProcess, :type => type config.include ::Rails::Controller::Testing::TemplateAssertions, :type => type config.include ::Rails::Controller::Testing::Integration, :type => type end end

Outside Rails

For projects and gems using controller tests outside of a Rails application, invoke the Rails::Controller::Testing.install method inside your test suite setup to include the required modules on controller test cases.

```ruby # test/test_helper.rb

require ‘rails-controller-testing’ Rails::Controller::Testing.install ```



assigns allows you to access the instance variables that have been passed to your views.

```ruby class PostsController < ActionController::Base def index @posts = Post.all end end

class PostControllerTest < ActionController::TestCase def test_index get :index assert_equal Post.all, assigns(:posts) end end ```


assert_template allows to you assert that certain templates have been rendered.

ruby class PostControllerTest < ActionController::TestCase def test_index get :index assert_template 'posts/index' end end
