Question

Así que soy nuevo en TDD y estoy arrojando algunos errores Rspec aquí en mis pruebas ... Básicamente después de ejecutar la especificación bundle exec rspec, obtengo un error de undefined method ''visit'' en algunas de mis especificaciones. Cualquier ayuda sobre cómo hacer pasar estas pruebas sería muy apreciada: gracias.

Mis especificaciones / solicitudes / user_pages_spec.rb

require ''spec_helper''

describe "User pages" do

  subject { page }

  describe "profile page" do
    let(:user) { FactoryGirl.create(:user) } # Code to make a user variable
    before { visit user_path(user) }

    before { visit signup_path }

    it { should have_selector(''h1'',    text: ''Sign up'') }
    it { should have_selector(''title'', text: ''Sign up'') }
  end
end

Y mis especificaciones / modelos / user_spec.rb

require ''spec_helper''

describe User do

before do
  @user = User.new(name: "Example User", email: "[email protected]",
                  password: "foobar", password_confirmation: "foobar")
end

subject { @user }

it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should respond_to(:password) }
it { should respond_to(:password_confirmation) }
it { should respond_to(:authenticate) }

it { should be_valid }

end

describe "when email format is invalid" do
  it "should be invalid" do
    addresses = %w[user@foo,com user_at_foo.org example.user@foo.
                   foo@bar_baz.com foo@bar+baz.com]
    addresses.each do |invalid_address|
      @user.email = invalid_address
      @user.should_not be_valid
    end      
  end
end

describe "when email format is valid" do
  it "should be valid" do
    addresses = %w[[email protected] [email protected] [email protected] [email protected]]
    addresses.each do |valid_address|
      @user.email = valid_address
      @user.should be_valid
    end      
  end
end

describe "when email address is already taken" do
  before do
    user_with_same_email = @user.dup
    user_with_same_email.email = @user.email.upcase
    user_with_same_email.save
  end
  it { should_not be_valid }
end

describe "when password is not present" do
  before { @user.password = @user.password_confirmation = " " }
  it { should_not be_valid }
end

describe "with a password that''s too short" do
  before { @user.password = @user.password_confirmation = "a" * 5 }
  it { should be_invalid }
end

describe "return value of authenticate method" do
  before { @user.save }
  let(:found_user) { User.find_by_email(@user.email) }

  describe "with valid password" do
    it { should == found_user.authenticate(@user.password) }
  end

  describe "with invalid password" do
    let(:user_for_invalid_password) { found_user.authenticate("invalid") }

    it { should_not == user_for_invalid_password }
    specify { user_for_invalid_password.should be_false }
  end
end 

describe "when password doesn''t match confirmation" do
  before { @user.password_confirmation = "mismatch" }
  it { should_not be_valid }
end

describe "when password confirmation is nil" do
  before { @user.password_confirmation = nil }
  it { should_not be_valid }
end

end

Y, por último, mi opinión / users / new.html.erb

<% provide(:title, ''Sign up'') %>
<h1>Sign up</h1>
<p>Find me in app/views/users/new.html.erb</p>

y views / users / show.html.erb

<% provide(:title, @user.name) %>
<h1><%= @user.name %></h1>

Y agregué mi UsersController

class UsersController < ApplicationController
  def new
  end

  def show
   @user = User.find(params[:id])
  end
end

También obteniendo este nuevo error ahora después de solucionarlo según la solución de Billy

Answer 1

El problema está aquí:

./spec/requests/user_pages_spec.rb

Pones las pruebas de integración de Capybara en la carpeta de requests . Es por eso que la visit al método no funcionará.

Para solucionarlo, simplemente mueva todas las pruebas de spec/requests a spec/features .

Answer 2

Esto sucede porque estás tratando de usar el método de visit de Capybara::DSL . Si revisas la documentación :

Capybara is no longer supported in request specs as of Capybara 2.0.0. The recommended way to use Capybara is with feature specs.

Para resolver este problema, debe mover sus pruebas a la carpeta de spec/features o incluir Capybara::DSL para las especificaciones de la solicitud:

#spec_helper.rb
RSpec.configure do |config|
  #...
  config.include Capybara::DSL, :type => :request
