Rails::Controller::Testing

This gem brings back

assigns
to your controller tests as well as
assert_template
to both controller and integration tests.

These methods were removed in Rails 5.

Installation

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

RSpec

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
.
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.
# test/test_helper.rb

require 'rails-controller-testing' Rails::Controller::Testing.install

Usage

assigns

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

assert_template
allows to you assert that certain templates have been rendered.
class PostControllerTest < ActionController::TestCase
  def test_index
    get :index
    assert_template 'posts/index'
  end
end
