Testing RESTful actions of multiple Rails controllers with RSpec can generate a lot of code repetition. The following code is my first attempt at using shared examples to DRY things up.
Here is what I don't like about the code, could not find a better way and would like your help to improve:
The shared examples require that specific variables are set within let blocks within the controller spec (high coupling). I have tried to use the model name to infer the factory name and create the test data within the share examples. It works well to create the record and records variables. However, some models require the presence of associations and FactoryGirl.attributes_for does not create associated records, so validation fails. So, valid_attributes are created differently for different models. The only (likely bad) way I could think of creating valid_attributes within shared examples is to pass a string containing the code used to create the attributes and evaluate it (eval) within the shared examples
The tests that assert redirection use eval to call Rails' route/path helpers. Different controllers in this app have different redirect behaviors. After creating or updating a record, some controllers redirect to the #show action, others to #index. The problem is that when expecting a redirect to #show, AFAIK, we have to know the record ID in order to build the expected URL. And we don't know the record ID within the controller spec. We only know it within the shared examples. So how can we pass an expected redirect URL from the controller spec to the shared example if we do not yet know what that URL is (because we don't know the record ID)?
Also, please let me know if you spot any additional issues.
The controller spec:

Probably not an answer but too long for a comment:
First of all you can wrap all of those in a shared_examples_for block e.g.
shared_examples_for 'a CRUD Controller' do
context "GET #index" do
it "requires login" do
sign_out current_user
get :index
expect(response).to require_login
end
####
end
context "GET #show" do
it "requires login" do
sign_out current_user
get :show, id: record
expect(response).to require_login
end
####
end
end
Secondly You can have shared examples inside shared examples to the above can be
shared_examples_for 'a CRUD Controller' do
shared_examples_for 'authenticatable' do |view:,params:{}|
it "requires login" do
sign_out current_user
get view, **params
expect(response).to require_login
end
end
context "GET #index" do
it_behaves_like 'authenticatable', view: :index
####
end
context "GET #show" do
it_behaves_like 'authenticatable', view: :show, id: record
####
end
end
Third you can assign variables inside a it_behaves_like block eg.
RSpec.describe QuotesController, :focus, :type => :controller do
login_admin
it_behaves_like 'a CRUD Controller' do
let(:model) { Quote }
let(:record) { FactoryGirl.create(:quote) }
let(:records) { FactoryGirl.create_pair(:quote) }
let(:valid_attributes) { FactoryGirl.attributes_for(:quote, quote: "New quote") }
let(:invalid_attributes) { valid_attributes.update(quote: nil) }
end
end
Fourth this too can be simplified
shared_examples_for 'a CRUD Controller' do |model:|
singular,plural = 2.times.map { |n| model.name.pluralize(n).underscore.to_sym }
let(:record) { FactoryGirl.create(singular)
let(:records) {FactoryGirl.create_pair(singular) }
let(:valid_attributes) do
# build should create the nested associations correctly as long
# as your factories are right
FactoryGirl.build(singular).attributes.delete_if do |k,_|
# this is because ActiveRecord#attributes contains columns
# you don't want to be considered updateable
["id","created_at","updated_at"].include?(k)
end
end
let(:invalid_attributes) do
# create an :invalid trait in your factory so that
# you don't have to worry about the model
FactoryGirl.build(singular, :invalid).attributes.delete_if do |k,_|
["id","created_at","updated_at"].include?(k)
end
end
####
end
RSpec.describe QuotesController, :focus, :type => :controller do
login_admin
it_behaves_like 'a CRUD Controller', model: Quote
end
Finally you are going to find that using a memoized let! will help drastically since you are creating an extraordinary amount of records in those tests as it stands now. This will degrade performance drastically and if you get to a model that has certain globally unique attributes your tests will fail everywhere.
Hopefully this helps start pointing you in the right direction
Update to control testing actions
shared_examples_for 'a CRUD Controller' do |model:|
accessible_method = ->(meth) { public_methods.include?(meth) }
context "GET #index", if: controller.method_defined?(:index) do
it_behaves_like 'authenticatable', view: :index
####
end
context "GET #show", if: controller.method_defined?(:show) do
it_behaves_like 'authenticatable', view: :show, id: record
####
end
end
Here is the improved code (based on engineersmnky's suggestions). Any suggestions for further improvements are welcome.

For the let blocks, does it not work if you pass in the model as a parameter to the shared example like you do with the redirect_path_helper?
include_examples "GET #index", Quote
and then in your shared_example you can use the record_name method to create record and records from FactoryGirl and generate valid_attributes and invalid_attributes (you could create an :invalid_quote factory as well for invalid attributes, not sure if that's considered a good practice/idea with FactoryGirl though) from there.
For the second problem, you don't need to use the named route helpers, url_for(controller: :quote) and url_for(#quote) should both work.
Here is my create action for users:
def create
#user = User.new(user_params)
if #user.save
respond_to do |format|
format.html {
redirect_to edit_admin_user_path(#user)
flash[:success] = "Successfully created"
}
end
else
render :new
flash[:alert] = "Something went wrong"
end
end
My test is looking like this:
context "POST methods" do
describe "#create" do
it "renders the edit template" do
post :create, user: FactoryGirl.attributes_for(:user)
expect(response).to render_template(:edit)
end
end
end
However I'm getting this error:
Failures:
1) Admin::UsersController POST methods #create renders the edit template
Failure/Error: expect(response).to render_template(:edit)
expecting <"edit"> but was a redirect to <http://test.host/admin/users/80/edit>
I want to check if the edit.html.haml file is rendered after creating a user. What am I doing wrong?
Update #1
I do check for redirect in another test, this is my full test suite:
require 'rails_helper'
RSpec.describe Admin::UsersController, type: :controller do
render_views
context "POST methods" do
describe "#create" do
it "using valid params" do
expect{
post :create, user: { email: "something#hello.com", password: "long12345678" }
}.to change(User, :count).by(1)
# get user_path('1')
end
it "redirects to the edit page after saving" do
post :create, user: FactoryGirl.attributes_for(:user)
user = User.last
expect(response).to redirect_to(edit_admin_user_path(user.id))
end
it "renders the edit template" do
post :create, user: FactoryGirl.attributes_for(:user)
user = User.last
expect {
redirect_to(edit_admin_user_path(user.id))
}.to render_template(:edit)
end
context "it redirects to new" do
it "if user has no valid mail" do
post :create, user: { email: "something", password: "long12345678" }
expect(response).to render_template(:new)
end
it "if user has no valid password" do
post :create, user: { email: "something#mail.com", password: "short" }
expect(response).to render_template(:new)
end
end
end
end
end
What I want is to actually check if the edit template is rendered. Because with expect(response).to redirect_to(edit_admin_user_path(user)) it does not check the template. This test passes even if I have no edit.html.haml file at all.
When you're testing create action you should just check correctness of redirect. In this action you're not actually rendering edit template, but you're just making redirect to the edit path of created entity. So this is the thing you should check.
describe "#create" do
it "redirects to the edit path" do
post :create, user: FactoryGirl.attributes_for(:user)
expect(response).to redirect_to(edit_admin_user_path(User.last))
end
end
Then you should have another test for edit action, where you're checking template rendering. That will mean that after redirect in create action you also will see the proper template.
You are redirecting to edit_admin_user_path after successfully saving the User in your controller action. But, you're testing render in the test instead.
Update your test as below.
context "POST methods" do
describe "#create" do
before(:each) do
#user = FactoryGirl.attributes_for(:user)
end
it "renders the edit template" do
post :create, user: #user
expect(response).to redirect_to(edit_admin_user_path(#user))
end
end
end
With which matcher and how can I test if the #post_comment and #post_comment.user is properly assigned?
expect(assigns(:post_comment)).to be_a_new(PostComment) is not working here.
UPDATE:
With the following setup I also get the following error. What should I change to be able to test the invalid attrs?

end
How to test these two?
expect(assigns(:post_comment)).to be_a_new(PostComment)
expect(assigns(:post_comment.user)).to eq(#user)
I believe you shoudl test not a new record, but a record of a class, and persisted record:
expect(assigns(:post_comment)).to be_a(PostComment)
expect(assigns(:post_comment)).to be_presisted
expect(assigns(:post_comment.user)).to eq(#user)
Excessive code.
#post_comment.save!
if #post_comment.save
You shall to keep only the single record of that, I believe it is enough save with exception:
#post_comment.save!
So other part code you can pick out of if block. Exception from save! you shall to trap with rescue_from.
I have a test I'm trying to pass but I can't get it to pass, I am new to this.

Perhaps #user is carried on as being logged in from one test to the next, so the 2nd show succeeds. Try to sign off the user whithin the first test.
As this is not the case, check your config/routes.rb.
Resources requiring login should be wrapped within a do...end
authenticate(:user) do
resources :user
...other stuff
end
I have the following controller spec and expect topic to contain just one element(since DatabaseCleaner does the cleaning) except I get multiple topics.
describe "GET index" do
it "assigns all topics as #topics" do
topic = FactoryGirl.create(:topic)
get :index, {}
assigns(:topics).should eq([topic])
end
end
This is my database cleaner config -
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each, js: true) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each) do
DatabaseCleaner.start
DatabaseCleaner.clean
end
config.after(:each) do
DatabaseCleaner.clean
end
config.before(:all) do
DeferredGarbageCollection.start
end
config.after(:all) do
Defer
end
And, this is the factory for topic -
factory :topic do
sequence(:heading) { |seq| "Heading For Topic - #{seq}" }
sequence(:slug) { |seq| "slug-for-topic-#{seq}" }
sequence(:title) { |seq| "Title for Topic #{seq}" }
sequence(:description) { |seq| "Description for Topic #{seq}" }
sequence(:content) { |seq| "Content for Topic #{seq}" }
sequence(:link) { |seq| "Link for Topic #{seq}" }
site
# User should belong to site
user { association :user, site_id: site.id }
end
Why is the database not cleaned before the GET action?
Update
Controller for index(nothing fancy here)
def index
#topics = Topic.all.limit 10
respond_to do |format|
format.html
format.json { rendor json: #topics }
end
end
