How to test a controller with steps to use some action - ruby-on-rails

In my system, I have a user that have one company that have multiple accounts.
User sign in system using Devise, and have a virtual attribute called selected_company that was setted in CompaniesController.
I want to make multiple tests in AccountsController with this scenario.
I have this code to sign_in user, this code works well:
before :each do
#user = create(:user)
#user.confirm!
sign_in #user
end
But I must to have a specific context that I tried to code as:
context 'when user already selected a company' do
before :each do
#company = create(:company)
#account = create(:account)
#company.accounts << #account
#user.selected_company = #company
end
it "GET #index must assings #accounts with selected_company.accounts" do
get :index
expect(assigns(accounts)).to match_array [#account]
end
end
But this code won't work, when I run it I got this error:
undefined method `accounts' for nil:NilClass
My AccountsController#index have only this code:
def index
#accounts = current_user.selected_company.accounts
end
I'm new in rspec and TDD and I have some time to test everything I want, and I want to test everything to practice rspec.
I don't know if this is the best way to test this things, so I'm open to suggestions.

Replace with:
expect(assigns(:accounts)).to match_array [#accounts]
Note, :accounts instead of just account.
Also, as I see it, you don't have #accounts in your spec. Please declare that, too. :)

Probably you are not saving selected_company and when you call this on your controller it returns nil.
Try save #user.save after set selected_company:
context 'when user already selected a company' do
before :each do
#company = create(:company)
#account = create(:account)
#company.accounts << #account
#user.selected_company = #company
#user.save
end
it "GET #index must assings #accounts with selected_company.accounts" do
get :index
expect(assigns(accounts)).to match_array [#account]
end
end
Hope to help you.

Finaly, I found the problem!
I changed the before statement to:
before :each do
#company = create(:company)
#account = create(:account)
#company.accounts << #account
controller.current_user.selected_company = #company
end
And changed assigns(accounts) to assings(:accounts) (with symbol) in expect method.

Send variable to view in request spec

I'm working on my first complex test, and I need some help.
I need to create a user, sign him in, and fill a form as him. The page raises an error: undefined method first_name for nil:nilClass
Both functions are pretty easy, here is the test:
it "simulates creator onboard" do
#user = FactoryGirl.create(:user)
puts #user.onboard_token.size
visit onboard_path(:token => #user.onboard_token)
puts #user.nil?
expect(#user.active).to eq(false)
click_on('step-forward')
find('input[name="user[password"]').set "12345678"
find('input[name="user[password_confirmation"]').set "12346578"
find('input[name="commit"]').click
expect(response).to redirect_to(root_path)
expect(#user.active).to eq(true)
end
And here is the controller function:
def onboard
authorize(:user, :onboard?)
if params[:token].present?
if params[:token] != nil && params[:token].size == 40 && !User.where(onboard_token: params[:token]).empty?
#user = User.find_by_onboard_token(params[:token])
end
if !#user.nil?
sign_in(:user, #user)
#brand = #user.profile
sign_out(:user)
end
else
sign_out(:user)
redirect_to root_path
end
end
For some reason, it appears that the #user variable is not passed to the view. I made sure it is not nil, made sure to use the correct capybara functions, but still, #user is nil in view.
Did I miss something ?
Since you're using Selenium with Capybara this test has a number of issues
Objects created in the test thread aren't visible in the app thread if you're using transactional testing - https://github.com/jnicklas/capybara#transactions-and-database-setup
Actions in Capybara are asynchronous so trying to test values on an object immediately after triggering the action (without some kind of expecation on displayed content to make sure the action has completed) is going to be flaky
You can't use visit and 'response' at the same time
An object that is present? can't be nil
If there is a token but no user matches it your code with still attempt to render the view but with no #user and no #brand
To solve these you need to set up something like DatabaseCleaner and make sure you're using truncation or deletion strategy for tests using the selenium driver. That will allow objects created in the test thread to be visible in the app (in your case the user). Then your test should be something more like
it "simulates creator onboard" do
#user = FactoryGirl.create(:user)
visit onboard_path(:token => #user.onboard_token)
#You need to expect for something that should be on the screen before checking user.active - since this can occur before the visit has actually done anything
#expect(#user.reload.active).to eq(false)
click_on('step-forward')
find('input[name="user[password"]').set "12345678"
find('input[name="user[password_confirmation"]').set "12346578"
find('input[name="commit"]').click
expect(page).to have_current_path(root_path)
expect(#user.reload.active).to eq(true)
end
with a controller more like
def onboard
authorize(:user, :onboard?)
if params[:token].present? && params[:token].size == 40
#user = User.find_by_onboard_token(params[:token])
if !#user.nil?
sign_in(:user, #user)
#brand = #user.profile
sign_out(:user)
else
# do something here because it means the token was invalid
end
else
sign_out(:user)
redirect_to root_path
end

RSpec with multi tenancy - Why is this simple test failing?

What I'm doing
I recently implemented multi-tenancy (using scopes) following Multitenancy with Scopes (subscription required) as a guide. NOTE: I am using the dreaded "default_scope" for tenant scoping (as shown in Ryan's Railscast). Everything is working in browser just fine, but many (not all) of my tests are failing and I can't figure out why.
I built authentication from scratch (based on this Railscast: Authentication from Scratch (revised) - subscription required) and using an auth_token for "Remember me" functionality (based on this Railscast: Remember Me & Reset Password).
My question
Why is this test failing, and why do the two workarounds work? I've been stumped for a couple days now and just can't figure it out.
What I think is happening
I'm calling the Jobs#create action, and the Job.count is reducing by 1 instead of increasing by 1. I think what's happening is the job is being created, then the app is losing the 'tenant' assignment (tenant is dropping to nil), and the test is counting Jobs for the wrong tenant.
What's odd is that it's expecting "1" and getting "-1" (and not "0"), which implies it's getting a count (note that there's already a 'seed' job created in the before block, so it's probably counting "1" before calling #create), calling the create action (which should increase the count by 1 to 2 total), then losing the tenant and switching to a nil tenant where there are 0 jobs. So it:
Counts 1 (seed job)
Creates a job
Loses the tenant
Counts 0 jobs in the new (probably nil) tenant
...resulting in a -1 change in the Job.count.
You can see below that I've semi-confirmed this by adding ".unscoped" to my Job.count line in the test. This implies that the expected number of jobs is there, but the jobs just aren't in the tenant the app is testing under.
What I don't understand is how it's losing the tenant.
Code
I've tried to grab the relevant parts of my code, and I've created a dedicated single-test spec to make this as easy to dissect as possible. If I can do anything else to make this easy on possible answerers, just let me know what to do!

I think it's not that RSpec is ignoring the default scope but it's reset in the ApplicationController in the around filter by setting the current user to nil.
I encountered this issue with assigns(...) and it happened because the relation is actually resolved when you're evaluating assigns. I think this may also be the case with the expectation in your case.
UPDATE: In my situation, the cleanest solution I could find (though I still hate it) is to let the default scope leak through by not setting the current user to nil in test environment.
In your case this would amount to:
def scope_current_tenant
update_current_tenant
yield
ensure
Tenant.current_id = nil unless Rails.env == 'test'
end
I haven't tested it with your code but maybe this will help.
I managed to get my tests to pass, although I'm still not sure why they were failing to begin with. Here's what I did:
describe "POST create" do
context "with valid attributes" do
it "creates a new job" do
expect{ # <-- This is line 33 that's mentioned in the failure below
post :create, job: FactoryGirl.attributes_for(:job)
}.to change(Job.where(tenant_id: #tenant1.id),:count).by(1)
end
end
end
I changed:
change(Job,:count).by(1)
...to:
change(Job.where(tenant_id: #tenant1.id),:count).by(1)
NOTE: #tenant1 is the logged-in admin's tenant.
I assumed default_scopes would be applied in RSpec, but it seems they aren't (or at least not in the ":change" portion of an "expect" block). In this case, the default_scope for Job is:
default_scope { where(tenant_id: Tenant.current_id) }
In fact, if I change that line to:
change(Job.where(tenant_id: Tenant.current_id),:count).by(1)
...it will also pass. So if I explicitly mimic the default_scope for Job within the spec, it'll pass. This seems like confirmation that RSpec is ignoring my default_scope on Jobs.
In a way, I think my new test is a better way to make sure tenant data stays segregated because I'm explicitly checking counts within a particular tenant rather than implicitly checking the counts for a tenant (by assuming the count is in the "current tenant").
I'm marking my answer is correct because it's the only answer, and if someone else encounters this, I think my answer will help them get past the issue. That said, I really haven't answered my original question regarding why the test was failing. If anyone has any insight into why RSpec seems to be ignoring default_scope in "expect" blocks, that might help making this question useful for others.
I have the same issue of you guys. I didn't resolve in a way that makes me comfortable but is still better than verifying your RAILS_ENV. Take this example.
it "saves person" do
expect {
some_post_action
}.to change(Person, :count).by(1)
end
Every time i try to save the count method makes a select like:
"select count(*) from persons where tenant_id is null"
I manage to resolve this issue by setting Person.unscoped in the change method i changed this:
}.to change(Person, :count).by(1)
to this:
}.to change(Person.unscoped, :count).by(1)
It's not the best solution but i'm still trying to find a way to get around the default_scope.

Error Testing Create Action

I am trying to use factory girl to test my create action in rails. I keep getting:
"Event.count" didn't change by 1.
<2> expected but was
<1>.
When I run my tests. I don't believe I've done anything to change my tests or the controller:
My test looks like this:
test "should get create" do
assert_difference('Event.count') do
post :create, FactoryGirl.attributes_for(:event)
end
assert_not_nil assigns(:event)
assert_response :success
end
I've also tried using FactoryGirl.build(:event) as well. I've used that previously, and I think that is the right the method to be using from what I've read.
Here is my factory:
factory :event do
name 'First Event'
street '123 street'
city 'Chicago'
state 'IL'
date '1/12/2012'
end
Here is my controller action
def create
#event = Event.new(params[:event])
#event.save
end
Any idea what I'm doing wrong?
In order to scope out your error, try throwing a debugger in your action :
def create
#event = Event.new(params[:event])
debugger
#event.save
end
See if you manally resolve an #event.save and what errors might prevent that. :D

Ruby On Rails Function Testing :index with a polymorphic model

I have a polymorphic model called Address, I am trying to currently write some basic function tests for this model and controller. For the controller I am at a loss on how to go about this. For example I have another model called Patient, each Patient will have an address, so i have started writing the following function test, but i have no idea how to use "get" with a nested polymorphic resource. Now I was able to find some polymorphic test information on Fixtures here: http://api.rubyonrails.org/classes/Fixtures.html
but this will not help me test against the index. Any help is much appreciated im at a total and complete loss here.
FILE: test/functional/addresses_controller_test.rb
require 'test_helper'
class AddressesControllerTest < ActionController::TestCase
setup do
#address = addresses(:of_patient)
#patient = patients(:one)
activate_authlogic
end
test "patient addresses index without user" do
get :index <<<<<<<<<<<< what goes here????
assert_redirected_to :login
end
end
Assuming your controller is setup the way I think it might be:
def index
if #current_user
#addresses = #current_user.addresses.all
else
redirect_to login_path
end
end
Then the test will probably look like this:
test "patient addresses index without user" do
get :index, :patient_id => #patient.id
assert_redirected_to :login
end
test "patient addresses with user" do
#current_user = #patient
get :index, :patient_id => #patient.id
assert_response :success
end
The thing to keep in mind is that the index method needs the patient_id to process.

How to stub Restul-authentication's current_user method?

I'm trying to run the following spec:
describe UsersController, "GET friends" do
it "should call current_user.friends" do
user = mock_model(User)
user.should_receive(:friends)
UsersController.stub!(:current_user).and_return(user)
get :friends
end
end
My controller looks like this
def friends
#friends = current_user.friends
respond_to do |format|
format.html
end
end
The problem is that I cannot stub the current_user method, as when I run the test, I get:
Spec::Mocks::MockExpectationError in 'UsersController GET friends should call current
_user.friends'
Mock "User_1001" expected :friends with (any args) once, but received it 0 times[0m
./spec/controllers/users_controller_spec.rb:44:
current_user is a method from Restful-authentication, which is included in this controller. How am I supposed to test this controller?
Thanks in advance
You will need to mock a user and then pass it into the login_as method to simulate logging in the user.
#user_session = login_as(stub_model(User))
UserSession.stubs(:new).returns(#user_session)
