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

Question

I\'m trying to create a spec for a sign out flow by using factorygirl to create a user and then use Devise\'s sign_in method to authenticate the user, then use

Answer 1

I was having this problem when trying to sign_in a user in a before hook:

before(:context) do
  create(:skill, name: 'Google Maps API'.downcase)
  user = create(:user)
  sign_in user
end

Placing sign_in inside the before hook leads to:

Failure/Error: sign_in user

 NoMethodError:
   undefined method `env' for nil:NilClass

But placing it inside an example works fine:

shared_examples_for('an authenticated resource.') do
  describe 'An authenticated request' do
    it "responds with HTTP status OK" do
      user = create(:user)
      sign_in user
      make_request
      expect(response).to have_http_status(:ok)
    end
  end
end

But this can be improved, placing the sign_in into a before(:example) that will also work:

context 'allow search by keyword' do
  let!(:skill){ create(:skill, name: 'Google Maps API'.downcase) }
  let!(:user) { create(:user) }

  before(:example) { sign_in user }

  it 'finds matching records' do
    get :search, name: "Google Maps API", format: :json
    expect(assigns(:skills).size).to be(1)
  end
  it 'finds records that start with keyword'
  it 'finds records that end with keyword'
  it 'finds records that contains keyword'
end
