Authenticated RSpec testing and Factory Girl - ruby-on-rails

I'm writing basic tests for a simple CRUD rails application. I am using devise for authentication and Factory Girl for object creation whilst testing, after testing I am clearing the test.db with the Database Cleaner gem.
I am testing a controller with RSpec but need an admin user to be signed in for this to be a 'true' test.
So far I have been following documentation but I don't believe it is working.
I have a test which checks if the count has been changed by one:
describe "POST create" do
context "with valid attributes" do
it "creates a new room" do
expect{ post :create, room: FactoryGirl.attributes_for(:room) }.to change(Room,:count).by(1)
end
When I run the test suite I get the error:
expected #count to have changed by 1, but was changed by 0
From reading around it seems I need to setup authentication with my tests. To do this I have created relevant Factories:
# Devise User Class
factory :user do
email "basicuser#mvmanor.co.uk"
password "u"
password_confirmation "u"
admin false
customer false
end
# Admin
factory :admin, class: User do
email "basicadmin#mvmanor.co.uk"
password "a"
password_confirmation "a"
admin true
customer false
end
I have also created the relevant Devise mappings macros:
module UserControllerMacros
def login_admin
before(:each) do
#request.env["devise.mapping"] = Devise.mappings[:admin]
sign_in FactoryGirl.create(:admin) # Using factory girl as an example
end
end
def login_user
before(:each) do
#request.env["devise.mapping"] = Devise.mappings[:user]
sign_in FactoryGirl.create(:user) # Using factory girl as an example
end
end
end
I'm not sure if I'm heading in the right direction with this. I certainly need my controller tests to be authenticated.

Before the first describe statement add this:
let!(:admin) { FactoryGirl.create(:admin) }
before { subject.stub(current_user: admin, authenticate_user!: true) }
it should stub your authentication.
And one little trick for your happiness: add in your spec_helper.rb anywhere within
RSpec.configure do |config|
...
end
block this code:
config.include FactoryGirl::Syntax::Methods
and now you don't need to preface all factory_girl methods with FactoryGirl, so instead of FactoryGirl.create you can write just create.

RSpec with FactoryGirl explicit subject

I'm using RSpec with FactoryGirl within a Ruby on Rails environment for testing.
I want to specify my factories as follows:
factory :user do
role # stub
factory :resident do
association :role, factory: :resident_role
end
factory :admin do
association :role, factory: :admin_role
end
end
And I'd like to do something like this in my spec:
require 'rails_helper'
RSpec.describe User, type: :model do
context "all users" do
# describe a user
# subject { build(:user) }
# it { is_expected.to be_something_or_do_something }
end
context "residents" do
# describe a resident
# subject { build(:resident) }
# it { is_expected.to be_something_or_do_something }
end
context "admins" do
# describe a admin
# subject { build(:admin) }
# it { is_expected.to be_something_or_do_something }
end
end
Can this be done by explicitly setting the subject? When I do, I keep getting duplicate roles errors.
If anyone has any advice or suggestion, it would be greatly appreciated!
But this causes the user_spec.rb to use the :user factory.
No, it does not. Assuming you configured FactoryGirl correctly, RSpec can use whatever factory you'd like "on demand" in any test file. Configuration-wise, in rails_helper.rb throw this in:
RSpec.configure do |config|
# ...
config.include FactoryGirl::Syntax::Methods
# ...
end
Then, in your spec file:
require 'rails_helper'
RSpec.describe User, type: :model do
context "all users" do
let(:user) { create(:user) }
it 'is a user' do
# Here `user` is going to be a user factory
expect(user.unit).not_to be_present
end
end
context "residents" do
let(:user) { create(:resident) }
it 'is a resident' do
# Here `user` is going to be a resident factory
expect(user.unit).to be_present
end
end
context "admins" do
let(:user) { create(:admin) }
it 'is an admin' do
# Here `user` is going to be an admin factory
expect(user.role).to be('admin_role')
end
end
end
In short, you can use create(<factory_name>) on any factory definition that exists in any one of these paths:
test/factories.rb
spec/factories.rb
test/factories/*.rb
spec/factories/*.rb
Note that if you haven't placed the config.include FactoryGirl::Syntax::Methods inside your RSpec.configure, you can still create any factory, by doing FactoryGirl.create(<factory_name>) instead of create(<factory_name>).
I don't think you would want to stop them from auto loading, and I'm not actually sure what your use case is for not allowing them to load?
RSpec automagically fetches the factory for a spec
Rspec loads all the factories into memory when your spec helper loads I believe. Because your using factory inheritence your just loading each of these into memory before your tests run, nothing is being called, no objects are being created or built. They are just ready to use in your tests.
Are you getting a specific error or is there some case I'm not seeing that you need?
I found the solution to my problems here: https://github.com/thoughtbot/factory_girl/blob/master/GETTING_STARTED.md#associations
What I needed to use in my user factories was association :role, factory: :role, strategy: :build

RSpec testing Devise Mailer

I am new to RSpec and TDD and I am having difficulties writing a RSpec test to test if Devise is actually sending the confirmation email after a user signs up. I know that my application is working as expected because I have physically tested the functionality in both development and production. However, I am still required to write the RSpec test for this functionality and I cannot figure out how to send a confirmation email through RSpec tests.
factories/user.rb
FactoryGirl.define do
factory :user do
name "Jack Sparrow"
email { Faker::Internet.email }
password "helloworld"
password_confirmation "helloworld"
confirmed_at Time.now
end
end
spec/models/user_spec.rb
require 'rails_helper'
RSpec.describe User, type: :model do
describe "user sign up" do
before do
#user = FactoryGirl.create(:user)
end
it "should save a user" do
expect(#user).to be_valid
end
it "should send the user an email" do
expect(ActionMailer::Base.deliveries.count).to eq 1
end
end
end
Why is Devise not sending a confirmation email after I create #user? My test returns ActionMailer::Base.deliveries.count = 0. As I said, I am new to RSpec and TDD so am I completely missing something here?
Devise uses its own mailer, so try Devise.mailer.deliveries instead of ActionMailer::Base.deliveries if putting the test in the right controller's file doesn't work by itself.

Is there a better way to test this Rails controller with RSpec?

I have an Account model that validates that its subdomain is unique.
I'm trying to learn how to test controllers with RSpec.
Here's what I've come up with, but it's quite different than the generated RSpec test and i'm wondering if this is a good way to test this or if there's a better way.
My test:
describe "POST create" do
describe "with valid params" do
it "creates a new Account" do
original_count = Account.count
account = FactoryGirl.build(:account, :subdomain => 'newdomain')
post :create, {:account => account}
account.save!
new_count = Account.count
expect(new_count).to eq(original_count + 1)
end
...
EDIT
I forgot to point out the fact that in my spec_helper I have the code below. It is needed because of the way i'm handling subdomains:
config.before(:each, :type => :controller) do
#account = FactoryGirl.create(:account)
#user = FactoryGirl.create(:user)
#request.host = "#{#account.subdomain}.example.com"
sign_in #user
end
There is, by using Rspec's expect to change, and FactoryGirl's attributes_for (might need tweaking, not tested):
describe "POST create" do
describe "with valid params" do
it "creates a new Account" do
expect{
post :create, { account: attributes_for(:account) }
}.to change{Account.count}.by(1)
end
...
Validate your unique subdomain constraint in your unit tests, perhaps using shoulda-matchers:
describe Account do
it { should validate_uniqueness_of(:subdomain) }
end
I would make a controller spec a true unit test and not involve the database. Something like:
describe AccountsController do
describe '#create' do
it "creates a new Account" do
account_attrs = FactoryGirl.attributes_for :account
expect(Account).to receive(:create!).with account_attrs
post :create, account: account_attrs
end
end
end
I'd also have a feature spec (or a Cucumber scenario) that integration-tested the entire interaction of which the post to AccountsController was a part. Actually if I had a happy-path feature spec/scenario there would be no need to write the controller spec above, but I'd need controller specs for error paths (like trying to create an Account with the same subdomain as an existing Account) and other variations and I'd write them similarly to the spec above, by stubbing and mocking database calls.

Testing authentication with Sorcery and RSpec

I've spent far too long messing with this before asking for help. I can't seem to get RSpec and Sorcery to play together nicely. I've read through the docs on Integration testing with Sorcery and can post the login action properly, but my tests still doesn't think the user is logged in.
# spec/controllers/user_controller_spec
describe 'user access' do
let (:user) { create(:user) }
before :each do
login_user(user[:email], user[:password])
end
it "should log in the user" do
controller.should be_logged_in
end
end
And my login_user method
# spec/support/sorcery_login
module Sorcery
module TestHelpers
module Rails
def login_user email, password
page.driver.post(sessions_path, { email: email , password: password, remember_me: false })
end
end
end
end
The sessions controller handles the pages properly when I use them on the generated pages just fine. I tried outputting the results of the login_user method and it appears to properly post the data. How do I persist this logged in user through the tests? Does a before :each block not work for this? I'm just not sure where it could be running wrong and I'm pretty new to testing/RSpec so I may be missing something obvious. I'd appreciate any help.
Here's the output of the failed tests:
1) UsersController user access should log in the user
Failure/Error: controller.should be_logged_in
expected logged_in? to return true, got false
I just went through this yesterday. Here's what I did, if it helps.
Sorcery provides a test helper login_user that relies on a #controller object being available. This works great in controller specs, but doesn't work in integration tests. So the workaround in integration tests is to write another method (like the one you have above) to simulate actually logging in via an HTTP request (essentially simulating submitting a form).
So my first thought is that you should try renaming your method to login_user_post or something else that doesn't collide with the built-in test helper.
Another potential gotcha is that it looks to me like the Sorcery helper assumes that your user's password is 'secret'.
Here's a link to the built-in helper so you can see what I'm talking about:
https://github.com/NoamB/sorcery/blob/master/lib/sorcery/test_helpers/rails.rb
Good luck - I really like this gem except for this part. It is really only fully explained by patching together SO posts. Here's the code I use:
Integration Helper
module Sorcery
module TestHelpers
module Rails
def login_user_post(user, password)
page.driver.post(sessions_url, { username: user, password: password})
end
def logout_user_get
page.driver.get(logout_url)
end
end
end
end
Integration Spec (where user needs to be logged in to do stuff)
before(:each) do
#user = create(:user)
login_user_post(#user.username, 'secret')
end
Controller Spec (where the regular login_user helper works fine)
before(:each) do
#user = create(:user)
login_user
end
Note that login_user doesn't need any arguments if you have an #user object with the password 'secret'.
Did you try adding to spec/spec_helpers.
RSpec.configure do |config|
# ...
config.include Sorcery::TestHelpers::Rails::Controller
end
Nota that you need to include Sorcery::TestHelpers::Rails::Controller, not just Sorcery::TestHelpers::Rails.
Then you will be able to login_user from any controller specs like:
describe CategoriesController do
before do
#user = FactoryGirl::create(:user)
end
describe "GET 'index'" do
it "returns http success" do
login_user
get 'index'
expect(response).to be_success
end
end
end
The way you pass a password is probably wrong. It may be encrypted at this point. In provided example I will try to do this at first:
describe 'user access' do
let (:user) { create(:user, password: 'secret') }
before :each do
login_user(user[:email], 'secret')
end
it "should log in the user" do
controller.should be_logged_in
end
end
This seems to be very poorly documented. The above solutions did not work for me. Here's how I got it to work:
Check your sessions_url. Make sure it is correct. Also, check what params are necessary to log in. It may be email, username, etc.
module Sorcery
module TestHelpers
module Rails
def login_user_post(email, password)
page.driver.post(sessions_url, { email:email, password: password })
end
end
end
end
RSpec config:
config.include Sorcery::TestHelpers::Rails
Spec helper:
def app
Capybara.app
end
spec/controllers/protected_resource_spec.rb:
describe UsersController do
before do
# Create user
# Login
response = login_user_post( user.email, :admin_password )
expect( response.headers[ 'location' ]).to eq 'http://test.host/'
# I test for login success here. Failure redirects to /sign_in.
#cookie = response.headers[ 'Set-Cookie' ]
end
specify 'Gets protected resource' do
get protected_resource, {}, { cookie:#cookie }
expect( last_response.status ).to eq 200
end

How do I simulate a login with RSpec?

I have been playing with Rails for a couple of years now and have produced a couple of passable apps that are in production. I've always avoided doing any testing though and I have decided to rectify that. I'm trying to write some tests for an app that I wrote for work that is already up and running but undergoing constant revision. I'm concerned that any changes will break things so I want to get some tests up and running. I've read the RSpec book, watched a few screencasts but am struggling to get started (it strikes me as the sort of thing you only understand once you've actually done it).
I'm trying to write what should be a simple test of my ReportsController. The problem with my app is that pretty much the entire thing sits behind an authentication layer. Nothing works if you're not logged in so I have to simulate a login before I can even send forth a simple get request (although I guess I should write some tests to make sure that nothing works without a login - I'll get to that later).
I've set up a testing environment with RSpec, Capybara, FactoryGirl and Guard (wasn't sure which tools to use so used Railscasts' suggestions). The way I've gone about writing my test so far is to create a user in FactoryGirl like so;
FactoryGirl.define do
sequence(:email) {|n| "user#{n}#example.com"}
sequence(:login) {|n| "user#{n}"}
factory :user do
email {FactoryGirl.generate :email}
login {FactoryGirl.generate :login}
password "abc"
admin false
first_name "Bob"
last_name "Bobson"
end
end
and then write my test like so;
require 'spec_helper'
describe ReportsController do
describe "GET 'index'" do
it "should be successful" do
user = Factory(:user)
visit login_path
fill_in "login", :with => user.login
fill_in "password", :with => user.password
click_button "Log in"
get 'index'
response.should be_success
end
end
end
This fails like so;
1) ReportsController GET 'index' should be successful
Failure/Error: response.should be_success
expected success? to return true, got false
# ./spec/controllers/reports_controller_spec.rb:13:in `block (3 levels) in <top (required)>'
Interestingly if I change my test to response.should be_redirect, the test passes which suggests to me that everything is working up until that point but the login is not being recognised.
So my question is what do I have to do to make this login work. Do I need to create a user in the database that matches the FactoryGirl credentials? If so, what is the point of FactoryGirl here (and should I even be using it)? How do I go about creating this fake user in the testing environment? My authentication system is a very simple self-made one (based on Railscasts episode 250). This logging in behaviour will presumably have to replicated for almost all of my tests so how do I go about doing it once in my code and having it apply everywhere?
I realise this is a big question so I thank you for having a look.
The answer depends on your authentication implementation. Normally, when a user logs in, you'll set a session variable to remember that user, something like session[:user_id]. Your controllers will check for a login in a before_filter and redirect if no such session variable exists. I assume you're already doing something like this.
To get this working in your tests, you have to manually insert the user information into the session. Here's part of what we use at work:
# spec/support/spec_test_helper.rb
module SpecTestHelper
def login_admin
login(:admin)
end
def login(user)
user = User.where(:login => user.to_s).first if user.is_a?(Symbol)
request.session[:user] = user.id
end
def current_user
User.find(request.session[:user])
end
end
# spec/spec_helper.rb
RSpec.configure do |config|
config.include SpecTestHelper, :type => :controller
end
Now in any of our controller examples, we can call login(some_user) to simulate logging in as that user.
I should also mention that it looks like you're doing integration testing in this controller test. As a rule, your controller tests should only be simulating requests to individual controller actions, like:
it 'should be successful' do
get :index
response.should be_success
end
This specifically tests a single controller action, which is what you want in a set of controller tests. Then you can use Capybara/Cucumber for end-to-end integration testing of forms, views, and controllers.
Add helper file in spec/support/controller_helpers.rb and copy content below
module ControllerHelpers
def sign_in(user)
if user.nil?
allow(request.env['warden']).to receive(:authenticate!).and_throw(:warden, {:scope => :user})
allow(controller).to receive(:current_user).and_return(nil)
else
allow(request.env['warden']).to receive(:authenticate!).and_return(user)
allow(controller).to receive(:current_user).and_return(user)
end
end
end
Now add following lines in spec/rails_helper.rb or spec/spec_helper.rb
file
require 'support/controller_helpers'
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
config.include ControllerHelpers, :type => :controller
end
Now in your controller spec file.
describe "GET #index" do
before :each do
#user=create(:user)
sign_in #user
end
...
end
Devise Official Link
The easiest way to login with a user on feature tests is to use the Warden's helper #login_as
login_as some_user
As I couldn't make #Brandan's answer work, but based on it and on this post, I've came to this solution:
# spec/support/rails_helper.rb
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } # Add this at top of file
...
include ControllerMacros # Add at bottom of file
And
# spec/support/controller_macros.rb
module ControllerMacros
def login_as_admin
admin = FactoryGirl.create(:user_admin)
login_as(admin)
end
def login_as(user)
request.session[:user_id] = user.id
end
end
Then on your tests you can use:
it "works" do
login_as(FactoryGirl.create(:user))
expect(request.session[:user_id]).not_to be_nil
end
For those who don't use Devise:
spec/rails_helper.rb:
require_relative "support/login_helpers"
RSpec.configure do |config|
config.include LoginHelpers
end
spec/support/login_helpers.rb:
module LoginHelpers
def login_as(user)
post "/session", params: { session: { email: user.email, password: "password" } }
end
end
and in the specs:
login_as(user)
