I have a test that looks like this:
test "should get create" do
current_user = FactoryGirl.build(:user, email: 'not_saved_email#example.com')
assert_difference('Inquiry.count') do
post :create, FactoryGirl.build(:inquiry)
end
assert_not_nil assigns(:inquiry)
assert_response :redirect
end
That's testing this part of the controller:
def create
#inquiry = Inquiry.new(params[:inquiry])
#inquiry.user_id = current_user.id
if #inquiry.save
flash[:success] = "Inquiry Saved"
redirect_to root_path
else
render 'new'
end
end
and the factory:
FactoryGirl.define do
factory :inquiry do
product_id 2
description 'I have a question about....'
end
end
but I keep getting errors in my tests:
1) Error:
test_should_get_create(InquiriesControllerTest):
RuntimeError: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
What am I doing wrong? I need to set the current_user, and I believe I am in the test, but obviously, that's not working.
You didn't create current_user. It was initialized only in test block.
There are two differents ways to do it:
First, use devise test helpers. Something like that
let(:curr_user) { FactoryGirl.create(:user, ...attrs...) }
sign_in curr_user
devise doc
Second, you can stub current_user method in your controllers for test env
controller.stub(current_user: FactroryGirl.create(:user, ...attrs...))
And you should use FactoryGirld.create(...) instead of FactoryGirl.build(...), because you factory objects have to be persisted.(be saved in db and has id attribute not nil)
There are several things which come to mind:
FactoryGirl.build(:user, ...) returns unsaved instance of a user. I'd suggest to use Factory.create instead of it, because with unsaved instance there's no id and there's no way for (usually session based) current_user getter to load it from database. If you're using Devise, you should "sign in" user after creating it. This includes saving record in DB and putting reference to it into session. See devise wiki
Also, passing ActiveRecord object to create action like this looks weird to me:
post :create, FactoryGirl.build(:inquiry)
Maybe there's some rails magic in play which recognizes your intent, but I'd suggest doing it explicitly:
post :create, :inquiry => FactoryGirl.build(:inquiry).attributes
or better yet, decouple it from factory (DRY and aesthetic principles in test code differ from application code):
post :create, :inquiry => {product_id: '2', description: 'I have a question about....'}
This references product with id = 2, unless your DB doesn't have FK reference constraints, product instance may need to be present in DB before action fires.

I am working on an online learning portal like bento. For a user to unlock the next lesson, they must have to review at least one submission from the other user on the assignment of any previous lessons(complete by the current user). Considering this logic, I have a rspec test where I have tested if the page is being redirected to the other user's submission or not? In order to pass the test, I have to create dummy submission. For that, I am using create() method but the redirection to submission page is failing on the test but it works fine on the website. The code responsible for redirection in submission_controller is
def review_submission
#submission = Submission.where('lesson_id < ?', current_user.submissions.last.assignment.lesson_id.to_i)
.shuffle[1]
if #submission.nil?
redirect_to #assignment
else
redirect_to assignment_submission_path(assignment_id: #assignment.id, id: #submission.id)
end
end
The code of the test is
it "redirects to submission path" do
admin_user = create(:admin_user)
sign_in admin_user
user = create(:user)
sign_in user
assignment = create(:assignment, admin_user_id: admin_user.id)
#I was creating dummy submissions data using rspec create method.
submission = create(:submission, lesson_id: 1)
post :create, params: { submission: attributes_for(:submission, user_id: user.id), assignment_id: assignment.id}
expect(response).to redirect_to assignment_submission_path( assignment_id: assignment.id, id: Submission.last.id)
end
Dummy data is coming from FactoryGirl
factory :submission do
user_id 1
assignment_id 1
lesson_id 2
content "this is the submission of my assignment"
factory :invalid_submission do
content ""
end
end
Any suggestions are highly appreciated. Thank you in advance.
It looks like #submission is nil, so it's redirecting you to the Attachments#show page instead of the Submissions#show page. You're setting it like:
#submission = Submission.where('lesson_id < ?', current_user.submissions.last.assignment.lesson_id.to_i).shuffle[1]
It's trying to find the Submission based on current_user.submissions. Your Factory is just making the submission like:
submission = create(:submission, lesson_id: 1)
That defaults the user_id to be 1, which probably isn't the ID of your signed in user (since you create the admin user above it). Try passing in the user_id to your FactoryGirl's creation of the Submission. May also want to pass in the assignment_id too actually, so the Submission will correctly belong to the Assignment.
submission = create(:submission, lesson_id: 1, user_id: user.id, assignment_id: assignment.id)
Then the Submission should be assigned to your User, and hopefully the Controller will find it and your test will pass.
I have a controller create action that creates a new blog post, and runs an additional method if the post saves successfully.
I have a separate factory girl file with the params for the post I want to make. FactoryGirl.create calls the ruby create method, not the create action in my controller.
How can I call the create action from the controller in my RSpec? And how would I send it the params in my factory girl factories.rb file?
posts_controller.rb
def create
#post = Post.new(params[:post])
if #post.save
#post.my_special_method
redirect_to root_path
else
redirect_to new_path
end
end
spec/requests/post_pages_spec.rb
it "should successfully run my special method" do
#post = FactoryGirl.create(:post)
#post.user.different_models.count.should == 1
end
post.rb
def my_special_method
user = self.user
special_post = Post.where("group_id IN (?) AND user_id IN (?)", 1, user.id)
if special_post.count == 10
DifferentModel.create(user_id: user.id, foo_id: foobar.id)
end
end
end
Request specs are integration tests, using something like Capybara to visit pages as a user might and perform actions. You wouldn't test a create action from a request spec at all. You'd visit the new item path, fill in the form, hit the Submit button, and then confirm that an object was created. Take a look at the Railscast on request specs for a great example.
If you want to test the create action, use a controller spec. Incorporating FactoryGirl, that would look like this:
it "creates a post" do
post_attributes = FactoryGirl.attributes_for(:post)
post :create, post: post_attributes
response.should redirect_to(root_path)
Post.last.some_attribute.should == post_attributes[:some_attribute]
# more lines like above, or just remove `:id` from
# `Post.last.attributes` and compare the hashes.
end
it "displays new on create failure" do
post :create, post: { some_attribute: "some value that doesn't save" }
response.should redirect_to(new_post_path)
flash[:error].should include("some error message")
end
These are the only tests you really need related to creation. In your specific example, I'd add a third test (again, controller test) to ensure that the appropriate DifferentModel record is created.
I'm testing to make sure that a created user is assigned to my instance variable #user. I understand what get means, but I'm not sure what to write for the test. I'm returning with an argument error for a bad URI or URL. What's wrong with my test and how do I fix it?
it "checks #user variable assignment for creation" do
p = FactoryGirl.create(:user)
get :users
# I'm confused on what this line above means/does. What does the hash :users refer
#to
assigns[:user].should == [p]
end
The expected URI object or string error refers to get :users and the error is as follows
Failure/Error get :users
ArgumentError:
bad argument: (expected URI object or URI string)
I guess that what you want is
it "checks #user variable assignment for creation" do
p = FactoryGirl.create(:user)
get :show, id: p.id
assigns(:user).should == p
end
The line you were not sure about checks that content of the assigned variable (#user) in the show view of the user p, is equal to the p user you just created more information there
what action are you trying to test? usually, for creation, you need to test that the controller's "create" action creates a user and assigns an #user variable
I would test it this way:
describe 'POST create' do
it 'creates a user' do
params = {:user => {:name => 'xxx', :lastname => 'yyy'}}
User.should_receive(:create).with(params)
post :create
end
it 'assigns the user to an #user instance variable' do
user = mock(:user)
User.stub!(:create => user)
post :create
assigns(:user).should == user
end
end
notice that I stub/mock all user methods, since you are testing a controller you don't have to really create the user, you only test that the controller calls the desired method, the user creation is tested inside the User model spec
also, I made 2 tests (you should test only 1 thing on each it block if possible, first it test that the controller creates a user, then I test that the controller assigns the variable
I'm assuming your controller is something like this:
controller...
def create
#user = User.create(params[:user])
end
which is TOO simple, I guess you have more code and you should test that code too (validations, redirects, flash messages, etc)
I have the following block of code in my User_spec.rb:
#user = { username:'newuser',
email:'new#user.com',
fname:'new',
lname:'user',
password:'userpw',
password_confirmation:'userpw'}
for creating a using using these attributes. However while I moved all these attributes to Factories.rb:
require 'factory_girl'
Factory.define :user do |u|
u.username 'newuser'
u.email 'new#user.com'
u.fname 'new'
u.lname 'user'
u.password 'newuserpw'
u.password_confirmation 'newuserpw'
end
and replace the line in user_spec.rb with:
#user = Factory(:user)
all my tests that related to the User model failed(such as tests for email, password, username etc), all were giving me
"undefined method `stringify_keys' for…"
the new user object
I had a similar problem, and it was because I was passing a FactoryGirl object to the ActiveRecord create/new method (whoops!). It looks like you are doing the same thing here.
The first/top #user you have listed is a hash of values, but the second/bottom #user is an instance of your User ojbect (built by FactoryGirl on the fly).
If you are calling something like this in your specs:
user = User.new(#user)
The first (hashed) version of #user will work, but the second (objectified) version will not work (and throw you the 'stringify_keys' error). To use the second version of #user properly, you should have this in your specs:
user = Factory(:user)
Hope that helps.
We need to see an example of a failing test to diagnose, but here is one thing that can cause it – sending an object when attributes are required. I once fixed one of my failing tests by changing:
post :create, organization: #organization
to
post :create, organization: #organization.attributes
#rowanu Answered your question, but let me layout my example too for future reference:
What was failing in my case was:
#user = User.new user_attr
#user.bookings_build(Booking.new booking_attr)
Note that I am trying to build with a booking instance and not hash of attributes
The working example:
user_attr_hash = FactoryGirl.attributes_for(:user)
booking_attr_hash = FactoryGirl.attributes_for(:booking)
#user = User.new user_attr_hash
#user.bookings.build(booking_attr_hash)
And in spec/factories/domain_factory.rb I have
FactoryGirl.define do
factory :user do
# DEFAULT USER...
password "123123123"
email "factory_girl#aaa.aaa"
# there rest of attributes set...
end
factory :booking do
start_date Date.today
end_date Date.today+3
# the rest of attributes
end
end
I'm trying to spec the controller code:
# ClustersController
def create
# create new cluster
#cluster.user = current_user
# save code
end
I am using Rails 3 / RSpec 2 and I'm fairly new to the TDD flow. I basically want to make sure that the user attribute is assigned during the create action.
To begin with i don't think you should create, update an save the object. You can pass the user to the create method, like this:
Cluster.create(:user => current_user)
And to test this you can do:
describe ClusterController do
describe "POST create" do
it "creates a new cluster" do
lamda do
post :create
end.should change(Cluster, :count).by(1)
end
it "set the current user as the new cluster's user" do
user = mock()
Cluster.should_receive(:create).with(:user => user)
post :create
assign(:cluster).user.should == user
end
end
end
I think that will do.
Hope that help.
