Failing Spec when passing Variables to test - ruby-on-rails

This is my Spec file:
require 'rails_helper'
RSpec.describe Programmes::ReportsController, :type => :controller do
let!(:programme) { create(:programme) }
context 'authenticated user' do
describe 'GET index' do
it 'responds with a 200 OK status code' do
get :index, params: { id: programme.id }
expect(response).to have_http_status(:success)
end
end
end
end
This is my Factory;
FactoryGirl.define do
factory :programme do
name { Faker::Lorem.word }
description { Faker::Lorem.sentence(3) }
end
end
This is my Controller;
class Programmes::ReportsController < ApplicationController
def index
end
def create
end
end
I can't seem to get this spec to pass. The route works fine in the browser; eg
http://localhost:3000/programmes/{:id}/reports
The error I have is:
Failures:
1) Programmes::ReportsController authenticated user GET index responds with a 200 OK status code
Failure/Error: let!(:programme) { create(:programme) }
NoMethodError:
undefined method `create' for #<RSpec::ExampleGroups::ProgrammesReportsController::AuthenticatedUser::GETIndex:0x007fac78b1b440>
# /Users/mike/.rvm/gems/ruby-2.2.3/gems/actionpack-5.0.0/lib/action_dispatch/testing/assertions/routing.rb:172:in `method_missing'
I am quite new to Ruby (and Rails). I don't think the Programme object is being created in FactoryGirl - but I don't really know how to find out if that's the case

Did you require 'factory_girl' in spec_helper?

Using rspec to test an API endpoint

I have this api endpoint wot get all the blogs from my database that works id the user pass an api_key. This works correctly and now I'm trying to testing this endpoint.
Routes:
Rails.application.routes.draw do
get 'blogs', to: 'blogs#index'
end
Blogs controller:
class BlogsController < ApplicationController
def index
if params[:api_key]
user = User.find_by(api_key: params[:api_key])
if user.present?
#blogs = Blog.all
return render json: #blogs, status: :ok
end
end
render json: { error: "Unauthorized!" }, status: :bad_request
end
end
I'm new to rspec and tests in general, I watched a couple videos and tutorials and this is what I have so far:
spec/requests/blogs_spec.rb
require 'rails_helper'
RSpec.describe 'Blogs API', type: :request do
let!(:blogs) { Blog.limit(10) }
describe 'GET /blogs' do
before { get '/blogs' }
it 'returns status code 400' do
expect(response).to have_http_status(400)
end
context 'when the request is valid' do
before { get '/blogs', params: { api_key: '123123'} }
it 'returns status code 400' do
expect(response).to have_http_status(200)
end
end
end
end
I can't seem to make the last test work and I don't know why. My guess is that I'm not passing api_key correctly, but I don't know how
1) Blogs API GET /blogs when the request is valid returns status code 400
Failure/Error: expect(response).to have_http_status(200)
expected the response to have status code 200 but it was 400
# ./spec/requests/blogs_spec.rb:28:in `block (4 levels) in <top (required)>'
Ok, so accordingly to your question + comments, I can assume you are running your tests within test environment, but you are expecting to find a User existing in development database.
FactoryBot
You might wanna use FactoryBot to create records for your testing suite.
Add to your Gemfile:
group :development, :test do
gem 'factory_bot_rails'
end
In rails_helper.rb, add:
RSpec.configure do |config|
config.include FactoryBot::Syntax::Methods
end
Now you should create your User factory. Create a new file spec/factories/user.rb with the following:
FactoryBot.define do
factory :user do
api_key { '123123' }
# You should define every any other required attributes here so record can be created
end
end
Finally, in your spec file:
....
context 'when the request is valid' do
before { get '/blogs', params: { api_key: user.api_key} }
let!(:user) { create(:user) }
it 'returns status code 200' do
expect(response).to have_http_status(200)
end
end
...
Now your test should pass. Notice that in testing database there is no Blog created also, so:
let!(:blogs) { Blog.limit(10) }
Will return an empty array. You will need to create a Blog factory too, and create blogs like:
let!(:blogs) { create_list(:blog, 2) }
Bonus
As soon as you start improving your tests, you may wanna take a look at Faker and Database Cleaner for ActiveRecord

Testing a before filter in rails controller

I seem to be stuck. I am trying to shore up some rspec testing and want to make sure the the correct before_filter methods are getting called for controllers. However, I am getting feedback saying the method never gets called.
The error:
Failure/Error: expect(controller).to receive(:authorize)
(#<UsersController:0x007fca2fd27110>).authorize(*(any args))
expected: 1 time with any arguments
received: 0 times with any arguments
The spec:
require "rails_helper"
RSpec.describe UsersController, :type => :controller do
let(:school){ FactoryGirl.create :school }
let(:user){ FactoryGirl.create :teacher}
before(:each){
allow(controller).to receive(:current_user).and_return(user)
school.teachers << user
}
context "Get #show" do
before(:each){ get :show, school_id: school.id, id: user.id }
it "responds successfully with an HTTP 200 status code" do
expect(controller).to receive(:authorize)
expect(response).to have_http_status(200)
end
it "renders the show template" do
expect(response).to render_template("show")
end
end
end
The controller:
class UsersController < ApplicationController
before_filter :authorize
def show
#user = User.find_by_id params[:id]
#school = #user.school
#coordinators = #school.coordinators
#teachers = #school.teachers
#speducators = #school.speducators
#students = #school.students
end
end
Manual testing shows that before is being called, and when I put a p in the authorize method it is called when I run the test, any thoughts on where the test is going wrong?
You must set method expectation before actual call, so your test should look like:
context "Get #show" do
subject { get :show, school_id: school.id, id: user.id }
it "calls +authorize+ befor action" do
expect(controller).to receive(:authorize)
subject
end
end

index rspec test failing

Im having difficulties with writing a spec for an index action of a controller im trying to test. The controller looks like this:
class MyGamesResultsController < ApplicationController
def index
#contest = Contest.find(params[:contest_id])
#my_entry = current_user.entries.where(contest_id: params[:contest_id])
#points_per_player = #my_entry[0].points_per_player
#total_points = #my_entry[0].total_points
end
end
and my spec looks like this:
require 'rails_helper'
RSpec.describe MyGamesResultsController, type: :controller do
describe 'GET /index' do
let!(:user) { create(:user) }
before :each do
sign_in user
get :index
end
it 'renders the index template' do
expect(subject).to render_template(:index)
end
end
end
The error that the spec returns says this:
Failure/Error: get :index
ActiveRecord::RecordNotFound:
Couldn't find Contest with 'id'=
Can anyone figure out what is wrong?
Solved it! had to do this:
require 'rails_helper'
RSpec.describe MyGamesResultsController, type: :controller do
describe "GET index" do
let!(:user) { create(:user) }
let!(:contest) { create(:contest) }
let!(:my_entry) { create(:entry, user_id: user.id, contest_id: contest.id) }
before :each do
sign_in user
get :index, contest_id: contest.id
end
it "renders the index template" do
(expect (response.status)).to eql(200)
end
end
end

rspec Ruby on Rails uninitialized constant RecipesController::Recipes

hello i'm doing some test of my application with Rspec (this is my very first time i'm using it)
this is my test file located in spec/controllers/recipes_controller_spec.rb:
require 'spec_helper'
describe RecipesController do
render_views
describe "index" do
before do
Recipe.create!(name: 'Baked Potato w/ Cheese')
Recipe.create!(name: 'Garlic Mashed Potatoes')
Recipe.create!(name: 'Potatoes Au Gratin')
Recipe.create!(name: 'Baked Brussel Sprouts')
xhr :get, :index, format: :json, keywords: keywords
end
subject(:results) { JSON.parse(response.body) }
def extract_name
->(object) { object["name"] }
end
context "when the search finds results" do
let(:keywords) { 'baked' }
it 'should 200' do
expect(response.status).to eq(200)
end
it 'should return two results' do
expect(results.size).to eq(2)
end
it "should include 'Baked Potato w/ Cheese'" do
expect(results.map(&extract_name)).to include('Baked Potato w/ Cheese')
end
it "should include 'Baked Brussel Sprouts'" do
expect(results.map(&extract_name)).to include('Baked Brussel Sprouts')
end
end
context "when the search doesn't find results" do
let(:keywords) { 'foo' }
it 'should return no results' do
expect(results.size).to eq(0)
end
end
end
end
when i try to execute it by the command:
bundle exec rspec spec/controllers/recipes_controller_spec.rb
i fail all my tests with this error:
Failure/Error: xhr :get, :index, format: :json, keywords: keywords
NameError:
uninitialized constant RecipesController::Recipes
# ./app/controllers/recipes_controller.rb:4:in `index'
# ./spec/controllers/recipes_controller_spec.rb:12:in `block (3 levels) in <top (required)>'
i've tried to look all my code but i haven't find out the error
NameError: uninitialized constant RecipesController::Recipes
means you used Recipes instead of Recipe somewhere (line 4 in index) in controller, and since your model is called Recipe (singular), you're getting NameError exception.

rspec controller subject instance_variables

I have a controller and tests it through rspec:
describe "GET 'index'" do
subject { get :index }
it { expect(subject).to render_template(:index) }
My controller generates instance variables passed to views, smth. like that:
#specifications = current_user.specifications
How can I test that controller pass instance variables correct?
Something like that:
it { expect(subject).assign(:contractors).to match_array(my_array) }
You can use controller helper test method
describe TetsController do
let(:user) { build_stubbed :user }
before do
controller.stub authenticate_user!: true,
current_user: user
end
describe 'GET index' do
let(:plans) { double :plans }
before do
expect(Plan).to receive(:all).and_return(plans)
end
it 'response success' do
get :index
expect(response).to be_success
end
it 'assign plans' do
get :index
expect(assigns(:plans)).to eq plans
end
end
end
Small example. controller has instance variable #plans. It's accessed as assigns(:plans)
