Devise testing controllers - minitest / rails4

secret_controller.rb

class SecretController < ApplicationController

  before_filter :authenticate_user!
  def show
  end
end

secret_controller_test.rb

require 'test_helper'

class SecretControllerTest < ActionController::TestCase
  include Devise::TestHelpers

  test "logged in should get show" do
    sign_in users(:one)
    get :show
    assert_response :success
  end

  test "not authenticated should get redirect" do
    get :show
    assert_response :redirect
  end

end

I did the same but I am getting the following error:
NoMethodError: undefined method `env' for nil:NilClass

Hi, @seemantasaha, please check this out.

• include Devise::Test::ControllerHelpers on its parent ActionController::TestCase superclass.
• include Devise::Test::IntegrationHelpers on its parent ActionDispatch::IntegrationTest superclass.

Maybe the root cause is that ControllerTest inherits from IntegrationTest:

class SecretControllerTest < ActionDispatch::IntegrationTest
  include Devise::Test::ControllerHelpers

So make sure what class you inherit from, FYI.

I did the same but a user is not signing in.
For logged in user also I am getting 302:
Expected response to be a , but was <302>

Found the error. I was not signing in as admin.
Can you describe here for the reference how it works with signing in as admin

Thank you!
