error using rspec for devise - ruby-on-rails

Question

I am using rspec for testing devise authentication. Following is my code
require 'spec_helper'
describe User do
describe "user registration" do
it "allows new users to register with an email address and password" do
get "/users/sign_up"
fill_in "Email", :with => "abc#example.com"
fill_in "Password", :with => "abc123"
fill_in "Password confirmation", :with => "abc123"
click_button "Sign up"
response.should have_content("Welcome! You have signed up successfully.")
end
end
end
I am getting the following error.
"NoMethodError:undefined method `get' for #"

Answer 1

You are using controller methods and integration test methods (Capybara) in a Model spec. It will not work.
A model spec (UNIT test) will contain things like:
Test your validators/relationships
Test scopes
Methods of your model
Check out this series of Blog articles on testing with RSpec, it should help:

Answer 2

This seems to be an model spec (describe User) which does not allow to run requests, but you probably want to write a controller spec (describe UsersController) or even an integration test.
If you are using the default rspec layout, just move your code to the appropriate directory (spec/controllers or spec/integration). I would do an integration test:
# In spec/integration/user_registration_spec.rb
require 'spec_helper'
describe "User registration" do
it "allows new users to register with an email address and password" do
get "/users/sign_up"
fill_in "Email", :with => "abc#example.com"
fill_in "Password", :with => "abc123"
fill_in "Password confirmation", :with => "abc123"
click_button "Sign up"
response.body.should have_content("Welcome! You have signed up successfully.")
end
end

Answer 3

Is this file in the spec/models directory? I'm guessing that's the case since you're describeing a User. The way you wrote your test is a mix between a controller-style test and an integration (acceptance) test. This is probably what you want:
require 'spec_helper'
describe User do
describe "user registration" do
it "allows new users to register with an email address and password" do
visit "/users/sign_up"
fill_in "Email", :with => "abc#example.com"
fill_in "Password", :with => "abc123"
fill_in "Password confirmation", :with => "abc123"
click_button "Sign up"
page.should have_content("Welcome! You have signed up successfully.")
end
end
end
Put this file in the spec/integration or spec/requests directory.

Answer 4

I would probably try something like this
require 'spec_helper'
describe User do
describe "user registration" do
it "allows new users to register with an email address and password" do
visit new_user_registration_path
current_path.should be(new_user_registration_path)
fill_in "user[email]", :with => "abc#example.com"
fill_in "user[password]", :with => "abc123"
fill_in "user[password_confirmation]", :with => "abc123"
click_button "Sign up"
expect { click_button submit }.to change(User, :count).by(1)
response.should be_redirect
response.should have_content("Welcome! You have signed up successfully.")
end
end
end
But I can highly recommend to using FactoryGirl for generating new values. Also check, which Devise modules do you use. For example if you are using a Confirmable modul, is obvious that this approach is wrong. Some useful article.
