Rspec route matching - same expected vs actual, yet error - ruby-on-rails

1) ExampleController routes for Example routes
Failure/Error: expect( post: '/api/application').to route_to( format: 'json', action: 'create_application', controller: 'example')
The recognized options <{"format"=>"json", "action"=>"create_application", "controller"=>"example"}> did not
match <{"format"=>"json", "action"=>"create_application",
"controller"=>"example"}>,
difference:.
<{"format"=>"json", "action"=>"create_application",
"controller"=>"example"}>
expected but was
<{"format"=>"json", "action"=>"create_application",
"controller"=>"example"}>.
Am I missing something here? I feel as if expected and actual are the same.
#charles
routes.rb:
scope '/api', :defaults => { format: 'json' } do
resource :application, only:[] do
post :create, to: 'example#create_application'
end
end
rake routes:
application POST /api/application(.:format) example#create_application
{:format=>"json"}
Working now with:
describe "routes for Example" do
it "routes" do
expect( post: '/api/application').to route_to( "example#create_application", :format=>"json" )
end
end

I was Having same issue.
You just need to add hash in route_to function like.
it 'routes to /v1/auth to user_token#create' do
expect(:post => '/v1/users/auth.json').to route_to({"format"=>"json", "controller"=>"v1/sessions", "action"=>"create"})
end
Like above.

I had the same issue.
My controller was: api/v1/users
My route was defined this was:
Rails.application.routes.draw do
namespace :api, defaults: { format: :json } do
namespace :v1 do
resources :users
end
end
end
And I was defining my spec route this way:
RSpec.describe Api::V1::UsersController, type: :routing do
describe "routing" do
it "routes to #index" do
expect(get: "api/v1/users").to route_to(controller: :api/v1/users, action: :index)
end
end
end
But each time I ran into the error:
The recognized options <{"format"=>"json", "action"=>"index", "controller"=>"api/v1/users"}> did not match <{"action"=>"index", "controller"=>"api/v1/users"}>
Here's how I fixed it:
I simply modified the spec route from this:
RSpec.describe Api::V1::UsersController, type: :routing do
describe "routing" do
it "routes to #index" do
expect(get: "api/v1/users").to route_to(controller: :api/v1/users, action: :index)
end
end
end
to this:
RSpec.describe Api::V1::UsersController, type: :routing do
describe "routing" do
it "routes to #index" do
expect(get: "api/v1/users").to route_to(format: :json, controller: "api/v1/users", action: "index")
end
end
end
That's all.
I hope this helps

Rails Api test UrlGenerationError

I am building an API and, upon writing the tests, I run into a strange UrlGenerator Error.
I have an API on version one and this is my Users controller.
class Api::V1::UsersController < ApplicationController
respond_to :json
def show
respond_with User.find(params[:id])
end
end
Here is the spec for that users controller
require 'rails_helper'
RSpec.describe Api::V1::UsersController, type: :controller do
before(:each) { request.headers['Accept'] = "application/vnd.marketplace.v1" }
describe "GET #show" do
before(:each) do
#user = FactoryBot.create :user
get :show, format: :json
end
it "returns the information about a reporter on a hash" do
user_response = JSON.parse(response.body, symbolize_names: true)
expect(user_response[:email]).to eql #user.email
end
it { should respond_with 200 }
end
end
When I run this spec I get the following error message: `Failure/Error: get :show, format: :json
ActionController::UrlGenerationError:
No route matches {:action=>"show", :controller=>"api/v1/users", :format=>:json}`
I have only one route for my API:
api_user GET /users/:id(.:format) api/v1/users#show {:subdomain=>"api", :format=>:json}
Does anybody know why I would be getting this error? It seems to me that, based on the route returned from the api routes list, this should be working. My routes.rb file is listed below:
namespace :api, defaults: { format: :json }, constraints: { subdomain: 'api' }, path: '/' do
scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do
resources :users, :only => [:show]
end
end
The problem is that the show route that you have defined requires an :id parameter, but the call for get :show from the test does not send it.
From Rspec, you can send the id with something like:
get :show, params: { id: #user.id }, format: :json

How to test session constrained routes with rspec routing specs?

I have such code in my routes.rb:
Rails.application.routes.draw do
authorized = ->(request) { request.session[:user_id].present? }
not_authorized = ->(request) { request.session[:user_id].blank? }
constraints authorized do
resources :users
end
constraints not_authorized do
get 'login' => 'auth#login_page'
post 'login' => 'auth#create_session'
get '*unmatched_route', to: 'auth#login_page'
root 'auth#login_page'
end
end
And I have such users_routing_spec.rb file:
require "rails_helper"
RSpec.describe UsersController, type: :routing do
describe "routing" do
it "routes to #index" do
expect(:get => "/users").to route_to("users#index")
end
end
end
This test fails as it routes to 'auth#login_page' because there is no user_id
in session.
How can I call auth#create_session in advance to the expectation?
There is no request or #request object and I also can't make a manual request to 'auth#create_session'

Rails Spec Controller Test failing with custom route

Rails 5.1
RSpec 3.6
I have a Controller:
class SessionController < ApplicationController
def new
end
end
A custom route:
get 'login' => 'sessions#new'
RSpec Test:
require 'rails_helper'
RSpec.describe SessionController, type: :controller do
describe "GET #new" do
before do
routes.draw { get "login" => "sessions#new" }
end
it "returns http success" do
get :login
expect(response).to have_http_status(:success)
end
end
end
and get error:
ActionController::UrlGenerationError: No route matches {:action=>"login", :controller=>"session"}
So "get" within a controller test seems always map to the action not the route. What should i do to get this test run? thanks in advance.
ActionController::UrlGenerationError: No route matches
{:action=>"login", :controller=>"session"}
Your controller name is SessionController, so your route should be
get 'login' => 'session#new' not get 'login' => 'sessions#new'
require 'rails_helper'
RSpec.describe SessionController, type: :controller do
describe "GET #new" do
before do
routes.draw { get "login" => "session#new" }
end
it "returns http success" do
get :login
expect(response).to have_http_status(:success)
end
end
end
Change it in your routes.rb as well.
When you are writing tests and you use the methods get, post, delete, etc., those methods assume that any parameter you pass them is the name of an action within the controller being tested. So, this works:
get :new
because it generates url_for(:controller => :sessions, :action => :new).
This doesn't work:
get '/login'
because it generates url_for(:controller => :sessions, :action => '/login').

ActionController::UrlGenerationError: No route matches action and controller

I couldn't find a solution in the other relative questions, so I'm asking my own.
The problem is pretty straightforward. This is the error I'm getting:
Failure/Error: get 'api/v2/special_keys#show'
ActionController::UrlGenerationError:
No route matches {:action=>"api/v2/special_keys#show", :controller=>"api/v2/special_keys"}
This is my routes.rb:
resources :special_keys, only: [] do
collection do
get '', to: 'special_keys#show'
end
end
This is the output from rake routes:
GET /api/v2/special_keys(.:format) api/v2/special_keys#show {:format=>"json"}
And my spec:
require 'rails_helper'
describe Api::V2::SpecialKeysController do
describe 'GET #show' do
it 'gets the policy and signature' do
get '/api/v2/special_keys'
expect(response.status).to eql 200
end
end
end
Try to rewrite your test as:
require 'rails_helper'
describe Api::V2::SpecialKeysController do
describe 'GET #show' do
it 'gets the policy and signature' do
get '/api/v2/special_keys', {format: :json}
expect(response.status).to eql 200
end
end
end
Try:
resource :special_keys, only: [:show]
The singular tells the app, that there is only one. So it will only generate a show action that needs no id and no indexaction at all.

Undefined method route_name in Rspec controller test

When running my controller test, I get this error:
NoMethodError:
undefined method `api_challenge_url' for #<Api::V1::ChallengesController:0x007f829b233460>
Which, is in fact, not a route that exists. My routes file looks like this:
namespace :api, { format: :json, constraints: { subdomain: 'api' }, path: '/'} do
scope module: :v1, constraints: ApiConstraints.new(version: 1, default: true) do
resources :users, only: [:show, :create, :update, :destroy] do
resources :challenges, only: [:create, :show]
end
end
end
And my controller test looks like this:
RSpec.describe Api::V1::ChallengesController, type: :controller do
describe "POST #create" do
context "when successfully created" do
before(:each) do
#user = FactoryGirl.create(:user)
#challenge_attributes = FactoryGirl.attributes_for(:challenge)
post :create, user_id: #user.id, challenge: #challenge_attributes, format: :json
end
it "should render the JSON for the created challenge" do
challenge_response = JSON.parse(response.body, symbolize_names: true)
expect challenge_response[:description].to eql #challenge_attributes["description"]
expect challenge_response[:title].to eql #challenge_attributes["title"]
end
end
end
end
But for the life of me, I can't why it's calling the wrong route name. The output of the relevant part of the rake routes looks like this:
api_user_challenges POST /users/:user_id/challenges(.:format) api/v1/challenges#create {:subdomain=>"api"}
I've tried a few different formats in the post method, is there some idiomatic way of doing this that I'm missing?
Try adding some configuration to include url helpers into your test suite:
RSpec.configure do |c|
c.include Rails.application.routes.url_helpers
# Other configurations ...
end
And if you prefer using xxx_url over xxx_path, remember to config action_controller.default_url_options in your config/environments/test.rb, for example:
config.action_controller.default_url_options = {
host: 'www.mysite.org',
protocol: 'https'
}
