NoMethodError: undefined method `setup' for RSpec::ExampleGroups::ApplicationsController:Class

Searching for this problem has only turned up issues with specific gems or classes that other people have dealt with. In my case, I think there's something wrong with rspec in general.

Whenever I generate a controler with rails generate ControllerName, it sets everything up and things seem to work fine. I've routed a few controllers and tested them in development and production and everything works.

The only thing that seems to be broken is testing them with rspec. Right now I have two controllers in my project, and whenever I run rspec/spec, most specs generated by rails g turns up this error:

NoMethodError:
  undefined method `setup' for RSpec::ExampleGroups::MoreStuffHere

For example, I have a WelcomeController and ApplicationsController and these are the errors I keep getting:

undefined method `setup' for RSpec::ExampleGroups::ApplicationsController:Class
undefined method `setup' for RSpec::ExampleGroups::WelcomeController:Class
undefined method `setup' for RSpec::ExampleGroups::WelcomeAboutHtmlErb:Class
undefined method `setup' for RSpec::ExampleGroups::WelcomeIndexHtmlErb:Class

Interestingly, I don't get errors for their helper_spec's

Here is a full error in case this helps:

An error occurred while loading ./spec/controllers/applications_controller_spec.rb.

Failure/Error:
  RSpec.describe ApplicationsController, type: :controller do

  end

NoMethodError:
  undefined method `setup' for RSpec::ExampleGroups::ApplicationsController:Class
# ./spec/controllers/applications_controller_spec.rb:3:in `<top (required)>'

Does anyone have any idea where this issue could lie?

IMHO the solution here is somewhat what Damian Rivas says there, but the important thing is:

  • in rails helper you have a line:

require 'spec_helper'

  • in spec_helper you have in config block line to include devise helpers:

config.include Devise::Test::ControllerHelpers, type: :controller

  • you also as said above have to have rspec/rails require line

The main point there was that you have to watch the order here... always including rspec/rails has to go before spec_helper

So lets say example spec_helper.rb looks like:

require 'rubygems'

Rspec.configure do |config|
  config.include Devise::Test::ControllerHelpers, type: :controller
end

Then our rails_hepler.rb has to look like:

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../config/environment', __dir__)
abort('The Rails environment is running in production mode!') if Rails.env.production?

require 'rspec/rails'
require 'spec_helper'

Then in sample_spec.rb you require rails_helper, or in my case I require through .rspec so I don't have to have it on top of every spec.

Hope it helps somebody :)

In spec_helper.rb I had

require File.expand_path("../../config/environment", __FILE__)
require 'rails/all'

RSpec.configure do |config|
  # More code here.
end

All I had to do was add require 'rspec/rails' under require 'rails/all'. This solved my problem.

Yet, I don't know why. If someone can elaborate that would be great. I already had require 'rspec/rails' in rails_herlper.rb, but obviously that wasn't good enough.
