How can I write test for "where" line - ruby-on-rails

I want to write controller test related password update test. I find authenticated person in the controller's first line with where condition. How can I write test related this line. I couldn't yiled any idea.
ChangePasswordsController
def update
person = Person.where(_id: session[:user_id]).first
identity = Identity.where(_id: person.user_id).first
unless params[:new_password] != params[:new_password_confirmation]
identity.password = params[:new_password].to_s
identity.password_confirmation = params[:new_password].to_s
identity.save
redirect_to root_url, :notice => "Password has been changed." + person.user_id
else
redirect_to :back, :alert => "Password & password confirmation are not match"
end
end
ChangePasswordsController Test
describe ChangePasswordsController do
setup do
request.env["omniauth.auth"] = OmniAuth.config.mock_auth[:identity]
#auth=request.env["omniauth.auth"]
end
it "should have edit action" do
get :edit
assert_response :success
end
it "should find person" do
...
end
it "should find identity" do
...
end
end

I don't think you should write a test whether the where finds a person or not. In this context you'd better just check whether the update method calls the find method on Person with the given parameter. Use something like this:
Person.should_receive(:find).with(id: <the userid you've setup for the test>) {[Person.new]}
It should be able to also check first but I can't remember, something to do with chainstubbing.

Rspec method is being called 2X, but can't find second time

Here is my controller spec
before do
#order = Order.new
end
it "should call find & assign_attributes & test delivery_start methods" do
Order.should_receive(:find).with("1").and_return(#order)
Order.any_instance.should_receive(:assign_attributes).with({"id"=>"1", "cancel_reason" => "random"}).and_return(#order)
Order.any_instance.should_receive(:delivery_start).and_return(Time.now)
post :cancel, order: {id:1, cancel_reason:"random"}
end
The failure is this:
Failure/Error: Unable to find matching line from backtrace
(#<Order:0x007fdcb03836e8>).delivery_start(any args)
expected: 1 time with any arguments
received: 2 times with any arguments
# this backtrace line is ignored
But I'm not sure why delivery_start is being called twice based on this controller action:
def cancel
#order = Order.find(cancel_params[:id])
#order.assign_attributes(cancel_params)
if (#order.delivery_start - Time.now) > 24.hours
if refund
#order.save
flash[:success] = "Your order has been successfully cancelled & refunded"
redirect_to root_path
else
flash[:danger] = "Sorry we could not process your cancellation, please try again"
render nothing: true
end
else
#order.save
flash[:success] = "Your order has been successfully cancelled"
redirect_to root_path
end
end
I would suggest you test the behavior and not the implementation. While there are cases where you would want to stub out the database doing it in a controller spec is not a great idea since you are testing the integration between your controllers and the model layer.
In addition your test is only really testing how your controller does its job - not that its actually being done.
describe SomeController, type: :controller do
let(:order){ Order.create } # use let not ivars.
describe '#cancel' do
let(:valid_params) do
{ order: {id: '123', cancel_reason: "random"} }
end
context 'when refundable' do
before { post :cancel, params }
it 'cancels the order' do
expect(order.reload.cancel_reason).to eq "random"
# although you should have a model method so you can do this:
# expect(order.cancelled?).to be_truthy
end
it 'redirects and notifies the user' do
expect(response).to redirect_to root_path
expect(flash[:success]).to eq 'Your order has been successfully cancelled & refunded'
end
end
end
end
I would suggest more expectations and returning true or false depending on your use. Consider the following changes
class SomeController < ApplicationController
def cancel
...
if refundable?
...
end
end
private
def refundable?
(#order.delivery_start - Time.now) > 24.hours
end
end
# spec/controllers/some_controller_spec.rb
describe SomeController, type: :controller do
describe '#cancel' do
context 'when refundable' do
it 'cancels and refunds order' do
order = double(:order)
params = order: {id: '123', cancel_reason: "random"}
expect(Order).to receive(:find).with('123').and_return(order)
expect(order).to receive(:assign_attributes).with(params[:order]).and_return(order)
expect(controller).to receive(:refundable?).and_return(true)
expect(controller).to receive(:refund).and_return(true)
expect(order).to receive(:save).and_return(true)
post :cancel, params
expect(response).to redirect_to '/your_root_path'
expect(session[:flash]['flashes']).to eq({'success'=>'Your order has been successfully cancelled & refunded'})
expect(assigns(:order)).to eq order
end
end
end
end
Sorry, this is a very unsatisfactory answer, but I restarted my computer and the spec passed...
One thing that has been a nuisance for me before is that I've forgotten to save the code, i.e., the old version of the code the test is running against called delivery_start twice. But in this case, I definitely checked that I had saved. I have no idea why a restart fixed it...

Rspec Test Failing

This following Controller test is failing, and I can't figure out why:
describe "GET 'index'" do
before(:each) do
#outings = FactoryGirl.create_list(:outing, 30)
#user = FactoryGirl.create(:user)
end
it "should be successful" do
get :index
response.should be_success
end
end
Rspec offers up the (rather unhelpful) error:
Failure/Error: response.should be_success
expected success? to return true, got false
Here's the code for the actual Controller, too:
def index
if #user
#outings = Outing.where(:user_id => #user.id)
#outing_invites = OutingGuest.where(:user_id => #user.id)
else
flash[:warning] = "You must log in to view your Outings!"
redirect_to root_path
end
end
Anyone have an idea what's causing my test to fail? I assume it may have something to do with the conditional in the Outing Controller, but I have no idea what a passing test would look like...
You're confusing instance variables between two separate classes - the controller is its own class and the specification is its own class. They don't share state. You could try this simple example to get a better understanding...
def index
// obvious bad code, but used to prove a point
#user = User.first
if #user
#outings = Outing.where(:user_id => #user.id)
#outing_invites = OutingGuest.where(:user_id => #user.id)
else
flash[:warning] = "You must log in to view your Outings!"
redirect_to root_path
end
end
I'll guess that FactoryGirl.create_list(:outing, 30) doesn't create an outing associating the first user with the outing since you're creating the user after you create the outing so your Outing.where will fail as well.
Its important to understand that when you are including the database in your test stack the database needs to contain the data in the way the test expects. So if your controller is querying for outings belonging to a specific user your spec needs to setup the environment such that the user the controller will retrieve (in this case, the terrible line with User.first from my example) will also have the outings associated with it that the specification is expecting.

Rails 3 / Capybara isn't saving model attributes

I'm trying to run a Capybara 1.0 test on my Rails 3 app to test whether when a user clicks on a confirmation link, he is actually confirmed.
Now, this actually works when I test it manually. In addition, as you can see there is a puts #user.confirmed line that I put in the confirm method to debug this, and it actually prints true when I run the test. However, the test itself fails.
It seems as if the confirmed attribute in my user model isn't being remembered by the test after executing the controller method.
What am I missing? Thanks so much in advance.
Test:
it "should allow a user to be confirmed after clicking confirmation link" do
fill_in('user_email', :with => 'test#test.com')
click_button('Submit')
#user = User.find_by_email('test#test.com')
#user.confirmed.should be_false
visit confirm_path(#user.confirmation_code)
#user.confirmed.should be_true
end
Controller method:
def confirm
#confirmation_code = params[:confirmation_code]
#user = User.find_by_confirmation_code(#confirmation_code)
#website = #user.website
#user.confirm
if #user.referrer_id
User.find(#user.referrer_id).increment_signups
end
flash[:success] = "Thanks for signing up!"
flash[:user_show] = #user.id
puts #user.confirmed
redirect_to "http://" + #website.domain_name
end
User model method:
def confirm
self.confirmed = true
self.save
end
Is it that you would need to reload the user object after visiting the confirm_path? Try this:
it "should allow a user to be confirmed after clicking confirmation link" do
fill_in('user_email', :with => 'test#test.com')
click_button('Submit')
#user = User.find_by_email('test#test.com')
#user.confirmed.should be_false
visit confirm_path(#user.confirmation_code)
#user = User.find_by_email('test#test.com')
#user.confirmed.should be_true
end
Alternatively you could use #user.reload.
The user object referred to in your test is just a copy of the object being manipulated by the application so it is not going to be automatically refreshed. You need to fetch it from the database a second time to get the updated values.

Why doesn't this RSpec stub work?

i have created an rspec test like :
it "should redirect to '/tavern' with an error if user already has a tavern quest" do
user = mock('User')
user.stub(:has_tavern_quest).and_return(true)
post :new_quest, :quest_type => 3
flash[:error].should_not be_nil
response.should redirect_to tavern_path
end
Then, i wrote the controller part :
# check if user already has a tavern quest
if current_user.has_tavern_quest?
flash[:error] = 'You already have a quest to finish !'
redirect_to tavern_path and return
end
And the model part :
def has_tavern_quest?
TavernQuest.exists?(self.id)
end
I would expect that the test succeeds, now but i get :
1) TavernController POST '/quest/' to get a new quest of quest_type == 3 should redirect to '/tavern' with an error if user already has a tavern quest
Failure/Error: flash[:error].should_not be_nil
expected: not nil
got: nil
# ./spec/controllers/tavern_controller_spec.rb:29
Do i have a mistake somewhere ?
THE MACRO FOR LOGIN USER :
module ControllerMacros
def login_user
before(:each) do
#request.env["devise.mapping"] = :user
#user = Factory.create(:user)
sign_in #user
end
end
end
Untested:
it "should redirect to '/tavern' with an error if user already has a tavern quest" do
controller.stub_chain(:current_user,:has_tavern_quest?).and_return(true)
post :new_quest, :quest_type => 3
flash[:error].should_not be_nil
response.should redirect_to tavern_path
end
Your mock doesn't do anything... perhaps you meant to use it somewhere?
I personally dislike mocking in this case and feel it's obfuscation. If you are using Devise you could use their test helpers to sign in as a user.

Cucumber/RSpec testing of improbable errors

I've got a problem testing the following controller code:
def publish
if #article.publish
flash[:notice] = "Article '#{#article.title}' was published."
else
# This is not tested
flash[:error] = "Error publishing article."
end
redirect_to :action => :index
end
Where the function publish looks like that:
def publish
self.toggle!(:is_published)
end
Function toggle! is atomic and in theory will fail only when there is a problem with database (in practice I can find number of scenarios where the error should be detected because someone breaks the publish method implementation). How can I test in Cucumber that the correct message is shown in case of error?
Here, check these out:
http://blog.flame.org/2009/11/19/how-i-test-ruby-on-rails-with-rspec-and-cucumber
it "tells me to bugger off (not admin)" do
login_user
users = make_users
get :index
flash[:error].should match "You must be an administrator to access this page."
response.should redirect_to(root_path)
end
Hope this helps :)
