“undefined method `env' for nil:NilClass” in 'setup_controller_for_warden' error when testing Devise using Rspec

Question

Answer 1

Like others have already said, you're including the Devise::TestHelpers. That's for testing controllers. If you'd still like to automatically login a test user in your integration tests, check out the official Devise Instructions on using it with Capybara.

Using Devise with Capybara

Basically, what you need to do is first enable Warden's test mode:

include Warden::Test::Helpers
Warden.test_mode!

Then, (create and) login your user:

user = FactoryGirl.create(:user)
login_as(user, scope: :user)

Example:

# spec/features/survey_spec.rb
require 'rails_helper'

feature 'survey app' do
    include Warden::Test::Helpers

    let(:user)   { create(:user) }
    let(:survey) { create(:survey_with_questions) }

    before do
        # Sign the User in
        Warden.test_mode!
        login_as(user, scope: user)
    end

    it 'renders the survey' do
        visit survey_show_path(survey)
        expect(page).to have_content(survey.title)
    end
end
