I'm trying to build a request spec which tests the full gamut of creating a new user via devise API.
I currently have this sitting in RegistrationsController spec, but this won't work if I want to follow the mail link to the confirmations controller.
I haven't been able to find a good example of how people have tested the 'hand-off' from one controller to another and the intermittent 'steps' (we have custom devise methods scattered throughout the process which this test will encompass too).
it "creates a user, sends a welcome email, confirms the user, and registers the user in email campaigns" do
post :create, {user: new_user_params}
last_email = ActionMailer::Base.deliveries.last.body
ConfirmationsController.any_instance.should_receive(:after_filter_method_to_subscribe_user)
redirect_to confirmation_link(last_email) # helper method
last_email.should include("Thanks for joining!")
user = User.find_by_first_name(new_first_name)
user.confirmed?.should be_true
user.email_lists.should_not be_empty
end
Edit:
I should also add that I need http_basic_auth to run the spec which I'm including in a spec/support file and sets the request.env['HTTP_AUTHORIZATION'] to variables stored in the API::Base controller. I currently have nil as a request obect when running specs in the spec/request folder, which I'll need to run the specs.
Edit:
Thanks to people who've taken a look. I figured it out after piecing together two SO searches and the code I had. I'll post an answer for future SO'ers when I can.
I figured this out shortly after posting my question with good luck finds on more google searches. Kudos to a couple SO references ~> request spec relish: http://goo.gl/iBg7v1 && setting request headers for http basic auth in request specs: http://goo.gl/hdDBMd
My spec turned out to look something like the below Hope this helps someone not waste 4 hours like me :).
spec/requests/api/user_registration_spec.rb.
it "sends a welcome email, confirms the user, and signs the user up to email campaigns" do
email_list = FactoryGirl.create(:email_list, name: "funky-email-campaign")
user_name = Api::RegistrationsController::USER
password = Api::RegistrationsController::PASSWORD
# post to /users/registration
post api_registrations_path({user: new_user_params}), nil , {'HTTP_AUTHORIZATION' => ActionController::HttpAuthentication::Basic.encode_credentials(user_name, password)}
last_email = ActionMailer::Base.deliveries.last.body
UserService.should_receive(:subscribe_to_email).and_call_original # check that after_filter is called
get confirmation_link(last_email) # follow link in email (/users/confirmation)
response.should redirect_to(custom_path) # tests after_confirmation_path_for override
last_email.should include(new_first_name)
last_email.should include("Thanks for joining!")
user = User.find_by_first_name(new_first_name)
user.confirmed?.should be_true
user.email_lists.first.name.should eq(email_list.name)
end
I want to keep on using the same session and by that I mean Rails' session between various Test::Unit integration tests that use Capybara. The Capybara::Session object is the same in all the tests as it is re-used, but when I access another page in another test, I'm immediately logged out.
Digging in I found that capybara_session.driver.browser.manage.all_cookies is cleared between one test and the next.
Any ideas how? or why? or how to avoid it?
Trying to work-around that, I saved the cookie in a class variable and re-added later by running:
capybara_session.driver.browser.manage.add_cookie(##cookie)
and it seems to work, the cookie is there, but when there's a request, the cookie gets replaced for another one, so it had no effect.
Is there any other way of achieving this?
Add the following after your capybara code that interacts with the page:
Capybara.current_session.instance_variable_set(:#touched, false)
or
page.instance_variable_set(:#touched, false)
If that doesn't work, these might help:

If what you are doing is trying to string together individual examples into a story (cucumber style, but without cucumber), you can use a gem called rspec-steps to accomplish this. For example, normally this won't work:
describe "logging in" do
it "when I visit the sign-in page" do
visit "/login"
end
it "and I fill in my registration info and click submit" do
fill_in :username, :with => 'Foo'
fill_in :password, :with => 'foobar'
click_on "Submit"
end
it "should show a successful login" do
page.should have_content("Successfully logged in")
end
end
Because rspec rolls back all of its instance variables, sessions, cookies, etc.
If you install rspec-steps (note: currently not compatible with rspec newer than 2.9), you can replace 'describe' with 'steps' and Rspec and capybara will preserve state between the examples, allowing you to build a longer story, e.g.:
steps "logging in" do
it "when I visit the sign-in page" #... etc.
it "and I fill in" # ... etc.
it "should show a successful" # ... etc.
end
You can prevent the call to #browser.manage.delete_all_cookies that happens between tests by monkey patching the Capybara::Selenium::Driver#reset! method. It's not a clean way of doing it, but it should work...
Add the following code to your project so that it is executed after you require 'capybara':
class Capybara::Selenium::Driver < Capybara::Driver::Base
def reset!
# Use instance variable directly so we avoid starting the browser just to reset the session
if #browser
begin
##browser.manage.delete_all_cookies <= cookie deletion is commented out!
rescue Selenium::WebDriver::Error::UnhandledError => e
# delete_all_cookies fails when we've previously gone
# to about:blank, so we rescue this error and do nothing
# instead.
end
#browser.navigate.to('about:blank')
end
end
end
For interest's sake, the offending line can be seen in Capybara's codebase here: https://github.com/jnicklas/capybara/blob/master/lib/capybara/selenium/driver.rb#L71
It may be worth posting the reason why you need this kind of behaviour. Usually, having the need to monkey patch Capybara, is an indication that you are attempting to use it for something it was not intended for. It is often possible to restructure the tests, so that you don't need the cookies persisted across integration tests.
I've been struggling with creating a login function that should be executed before any rspec test is run.
What I have right now is:
def login
post "/session", { "session[username]" => "bjones" }
end
in my spec_helper.rb file
Then, I have the following in one of my spec.rb files in the requests directory.
require 'spec_helper'
describe "Sessions" do
describe "GET /dashboards" do
login
it "displays the dashboard" do
get dashboard_path
puts response.body
end
end
end
However, when I try running the test, I get:
undefined method `post' for #<Class:0x4f08828> (NoMethodError)
I'm pretty new to rails and completely new to testing and rspec so maybe there's something fundamental I'm missing here. Basically, all I want to do is set that session variable so that when the test is run I will be logged in. Perhaps a different approach would be better? Or maybe I need to put that login function in a different place?
I came across this answer which was sort of useful but it's not for rspec so I'm having trouble understanding where such a helper function would go.
Try
let(:login) {
post "/session", { "username" => "bjones" }.to_json
}
This might have to be revised to use .to_json or not, depending on what content type the controller accepts.
Anyone have any tips for best practices for mocking out facebook requests in functional tests? Is it just as simple as adding all of the proper params to the request? Is there a way to stub those out?
I'm using facebooker, which comes with a mock service:
# A mock service that reads the Facebook response from fixtures
# Adapted from http://gist.github.com/44344
#
# Facebooker::MockService.fixture_path = 'path/to/dir'
# Facebooker::Session.current = Facebooker::MockSession.create
But when I write a basic get test, it tries to redirect the browser to the facebook page for adding the app, which I assume indicates that the mocking isn't working.
test "loads respondent" do
Facebooker::Session.current = Facebooker::MockSession.create
get :index
puts #response.body # => <html><body>You are being redirected.</body></html>
end
I got this working with the latest version of facebooker (1.0.58):
# test_helper.rb
require 'facebooker/mock/session'
require 'facebooker/mock/service'
Facebooker::MockService.fixture_path = File.join(RAILS_ROOT, 'test', 'fixtures', 'facebook')
Obviously you will have to create the facebook directory in fixtures, or put it wherever. Inside you have to add a folder for each facebook method, and an xml file for the different types of responses you want to test for. I had to add facebook.users.getInfo and facebook.users.hasAppPermission. The easiest is just to add a file named default.xml with the example code from the facebook wiki for those actions.
# Controller test
test "facebook action" do
get :index, {:fb_sig_added => true}, :facebook_session => Facebooker::MockSession.create
assert_response :success
end
The fb_sig_added param is necessary as far as I can tell, because the internal facebooker logic checks the params directly before checking the session on that one. Which seems a bit wanky to me but maybe there's a reason for that.
I am working on some Cucumber stories for a 'sign up' application which has a number of steps.
Rather then writing a Huuuuuuuge story to cover all the steps at once, which would be bad, I'd rather work through each action in the controller like a regular user. My problem here is that I am storing the account ID which is created in the first step as a session variable, so when step 2, step 3 etc are visited the existing registration data is loaded.
I'm aware of being able to access controller.session[..] within RSpec specifications however when I try to do this in Cucumber stories it fails with the following error (and, I've also read somewhere this is an anti-pattern etc...):
Using controller.session[:whatever] or session[:whatever]
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.session (NoMethodError)
Using session(:whatever)
wrong number of arguments (1 for 0) (ArgumentError)
So, it seems accession the session store isn't really possible. What I'm wondering is if it might be possible to (and I guess which would be best..):
Mock out the session store etc
Have a method within the controller and stub that out (e.g. get_registration which assigns an instance variable...)
I've looked through the RSpec book (well, skimmed) and had a look through WebRat etc, but I haven't really found an answer to my problem...
To clarify a bit more, the signup process is more like a state machine - e.g. the user progresses through four steps before the registration is complete - hence 'logging in' isn't really an option (it breaks the model of how the site works)...
In my spec for the controller I was able to stub out the call to the method which loads the model based on the session var - but I'm not sure if the 'antipattern' line also applies to stubs as well as mocks?
Thanks!
I'll repeat danpickett in saying mocks should be avoided whenever possible in Cucumber. However if your app does not have a login page, or perhaps performance is a problem, then it may be necessary to simulate login directly.
This is an ugly hack, but it should get the job done.
Given /^I am logged in as "(.*)"$/ do |email|
#current_user = Factory(:user, :email => email)
cookies[:stub_user_id] = #current_user.id
end
# in application controller
class ApplicationController < ActionController::Base
if Rails.env.test?
prepend_before_filter :stub_current_user
def stub_current_user
session[:user_id] = cookies[:stub_user_id] if cookies[:stub_user_id]
end
end
end
mocks are bad in cucumber scenarios - they're almost kind of an antipattern.
My suggestion is to write a step that actually logs a user in. I do it this way
Given I am logged in as "auser#example.com"
Given /^I am logged in as "(.*)"$/ do |email|
#user = Factory(:user, :email => email)
#user.activate!
visit("/session/new")
fill_in("email", :with => #user.email)
fill_in("password", :with => #user.password)
click_button("Sign In")
end
I realize that the instance variable #user is kind of bad form—but I think in the case of logging in/out, having #user is definitely helpful.
Sometimes I call it #current_user.
Re. Ryan's solution - you can open up ActionController in you env.rb file and place it there to avoid putting in your production code base (thanks to john # pivotal labs)
# in features/support/env.rb
class ApplicationController < ActionController::Base
prepend_before_filter :stub_current_user
def stub_current_user
session[:user_id] = cookies[:stub_user_id] if cookies[:stub_user_id]
end
end
I don't know how much this relates to the original question anymore, but I decided to post anyway in the spirit of discussion...
We have a cucumber test suite that takes > 10 minutes to run so we wanted to do some optimization. In our app the login process triggers a LOT of extra functionality that is irrelevant to majority of the scenarios, so we wanted to skip that by setting the session user id directly.
Ryanb's approach above worked nicely, except that we were unable to log out using that approach. This made our multi-user stories fail.
We ended up creating a "quick login" route that is only enabled in test environment:
# in routes.rb
map.connect '/quick_login/:login', :controller => 'logins', :action => 'quick_login'
Here is the corresponding action that creates the session variable:
# in logins_controller.rb
class LoginsController < ApplicationController
# This is a utility method for selenium/webrat tests to speed up & simplify the process of logging in.
# Please never make this method usable in production/staging environments.
def quick_login
raise "quick login only works in cucumber environment! it's meant for acceptance tests only" unless Rails.env.test?
u = User.find_by_login(params[:login])
if u
session[:user_id] = u.id
render :text => "assumed identity of #{u.login}"
else
raise "failed to assume identity"
end
end
end
For us this ended up being simpler than working with the cookies array. As a bonus, this approach also works with Selenium/Watir.
Downside is that we're including test-related code in our application. Personally I don't think that adding code to make application more testable is a huge sin, even if it does add a bit of clutter. Perhaps the biggest problem is that future test authors need to figure out which type of login they should use. With unlimited hardware performance we obviously wouldn't be doing any of this.
Re: Ryan's solution:
Does not work with Capybara, unless small adaptation done:
rack_test_driver = Capybara.current_session.driver
cookie_jar = rack_test_driver.current_session.instance_variable_get(:#rack_mock_session).cookie_jar
#current_user = Factory(:user)
cookie_jar[:stub_user_id] = #current_user.id
(found here: https://gist.github.com/484787)
My understanding is that you get:
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.session (NoMethodError)
when session[] is accessed before request has been instantiated. In your case, I'd imagine if you put webrats' visit some_existing_path before accessing session[] in your step defenition, the error will go away.
Now, unfortunately, session doesn't seem to persist across steps (at least, I couldn't find the way), so this bit of information doesn't help to answer your question :)
So, I suppose, Ryan's session[:user_id] = cookies[:stub_user_id]... is the way to go. Although, imo, test related code in the application itself doesn't sound right.
I use a testing-only sign-in solution like Prikka's, but I do it all in Rack instead of creating a new Controller and routes.
# in config/environments/cucumber.rb:
config.middleware.use (Class.new do
def initialize(app); #app = app; end
def call(env)
request = ::Rack::Request.new(env)
if request.params.has_key?('signed_in_user_id')
request.session[:current_user_id] = request.params['signed_in_user_id']
end
#app.call env
end
end)
# in features/step_definitions/authentication_steps.rb:
Given /^I am signed in as ([^\"]+)$/ do |name|
user = User.find_by_username(name) || Factory(:user, :username => name)
sign_in_as user
end
# in features/step_definitions/authentication_steps.rb:
Given /^I am not signed in$/ do
sign_in_as nil
end
module AuthenticationHelpers
def sign_in_as(user)
return if #current_user == user
#current_user = user
get '/', { 'signed_in_user_id' => (user ? user.to_param : '') }
end
end
World(AuthenticationHelpers)
#Ajedi32 I ran into the same issue (undefined method 'current_session' for Capybara::RackTest::Driver) and putting this in my step definition fixed the problem for me:
rack_test_browser = Capybara.current_session.driver.browser
cookie_jar = rack_test_browser.current_session.instance_variable_get(:#rack_mock_session).cookie_jar
cookie_jar[:stub_user_id] = #current_user.id
In my controller action, I referred to cookies[:stub_user_id], instead of cookie_jar[:stub_user_id]
Why don't you use FactoryGirl or (Fixjour or Fabricator) with Devise (or Authlogic) and SentientUser? Then you can simply sniff which user is already logged in!
#user = Factory(:user) # FactoryGirl
sign_in #user # Devise
User.current.should == #user # SentientUser
Another slight variation:
# In features/step_definitions/authentication_steps.rb:
class SessionsController < ApplicationController
def create_with_security_bypass
if params.has_key? :user_id
session[:user_id] = params[:user_id]
redirect_to :root
else
create_without_security_bypass
end
end
alias_method_chain :create, :security_bypass
end
Given %r/^I am logged in as "([^"]*)"$/ do |username|
user = User.find_by_username(username) || Factory(:user, :username => username)
page.driver.post "/session?user_id=#{user.id}"
end
After a lot of soul searching and web surfing, I finally opt'ed for a very simple and obvious solution.
Using cookies adds two problems. First you have code in the application specific for testing and second there is the problem that creating cookies in Cucumber is hard when using anything other than rack test. There are various solutions to the cookie problem but all of them are a bit challenging, some introduce mocks, and all of them are what I call 'tricky'. One such solution is here.
My solution is the following. This is using HTTP basic authentication but it could be generalized for most anything.
authenticate_or_request_with_http_basic "My Authentication" do |user_name, password|
if Rails.env.test? && user_name == 'testuser'
test_authenticate(user_name, password)
else
normal_authentication
end
end
test_authenticate does what ever the normal authenticate does except it bypasses any time consuming parts. In my case, the real authentication is using LDAP which I wanted to avoid.
Yes… it is a bit gross but it is clear, simple, and obvious. And… no other solution I've seen is cleaner or clearer.
Note, one feature is that if the user_name is not 'testuser', then the normal path is taken so they can be tested.
Hope this helps others...
