Question

In rails I have a before_filter that checks and requires that the user is an admin for certain actions in the controller.

However, I need to write tests for these controllers.

So, I have something that looks like this:

test "should get create" do
    assert_difference('Event.count') do
      post :create, FactoryGirl.build(:event)
    end
    assert_not_nil assigns(:event)
    assert_response :success
  end 

user_factory.rb:

FactoryGirl.define do

  factory :admin do
   email '[e-mail]'
   password 'password'
   password_confirmation 'password'
   admin true
  end
end

But need to login as an admin to be able to create the event. Any ideas on how to do this? The admin column is just a true/false column in the users table.

Edit: First Attempt:

 test "should get create" do
    admin = Factory(:admin)
    login_as(admin)
    assert_difference('Event.count') do
      post :create, FactoryGirl.build(:event)
    end
    assert_not_nil assigns(:event)
    assert_response :success
  end

generates error:

 1) Error:
test_should_get_create(EventsControllerTest):
NameError: uninitialized constant Admin

Update:

FactoryGirl.define do

  factory :user do
   email '[e-mail]'
   password 'password'
   password_confirmation 'password'
  end
end

and

test "should get create" do
    login_as(FactoryGirl.create(:user, admin: true))
    assert_difference('Event.count') do
      post :create, FactoryGirl.build(:event)
    end
    assert_not_nil assigns(:event)
    assert_response :success
  end

and I get the error test_should_get_create(EventsControllerTest):
NoMethodError: undefined method 'login_as' for #<EventsControllerTest:0x007fb4faec1b28>

When you define your factory(:admin), FactoryGirl looks for a class called Admin, which is why you’re getting that error.

You don’t need to create a separate factory for admin; you can simply use your User factory, passing in admin: true (that’ll override the default factory settings). So do admin = Factory(:user, admin: true). Make sure you have the user factory defined of course.

If you want to keep the :admin factory, you need to specify that the class is User. The syntax goes something like this:factory(:admin, class: "User").
