ruby-on-rails - 如何在 Rails4 测试中使用 Devise 登录/注销用户

Question

我正在努力确保使用 Devise in Rails 4 维护正确的用户访问权限，但我很难让用户登录到测试套件中。

最简单的情况:

require 'test_helper'
  include Devise::TestHelpers

class SiteLayoutTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:test1)
  end

  test "logged in should get index" do
    sign_in @user
    get users_path
    assert_response :success
    assert_select "title", "User Index"
  end
end

到目前为止，除了实现 Devise 和具有适当操作的用户 Controller 之外，我没有做更多的事情。

我一直得到:NoMethodError: undefined method 'env' for nil:NilClass，具体指的是包含 sign_in @user 的行，我可以找到 people 的其他实例遇到同样的错误，但似乎从未找到解决我试图解决的问题的实际解决方案。

我如何使用 Devise in Rails 4 登录用户以进行测试？谢谢。

编辑:

fixtures/users.yml

test1:
  id: '1'
  email: 'test1@example.com'
  encrypted_password: <%= Devise::Encryptor.digest(User, "password") %>
  created_at: <%= Time.now - 6.minutes %>
  updated_at: <%= Time.now - 4.minutes %>

原位解决方案:

test "logged in should get index" do
  post user_session_path, 'user[email]' => @user.email, 'user[password]' =>  'password'
  get users_path
  assert_response :success
  assert_select "title", "User Index"
end

这是来自他们的 docs :

"Do not use Devise::TestHelpers in integration tests."

您必须手动登录。这是一个测试网站的示例，该网站不允许用户在未登录的情况下访问根路径。您可以在支持文件中创建一个方法来手动登录用户，然后在您想要登录时调用它用户，这样您就不必在每次需要登录用户时都使用此代码。

require 'test_helper'

 class UserFlowsTest < ActionDispatch::IntegrationTest
   test "signed in user is redirected to root_path" do
     get user_session_path
     assert_equal 200, status
     @david = User.create(email: "david@mail.com", password: Devise::Encryptor.digest(User, "helloworld"))
     post user_session_path, 'user[email]' => @david.email, 'user[password]' =>  @david.password
     follow_redirect!
     assert_equal 200, status
     assert_equal "/", path
   end

   test "user is redirected to sign in page when visiting home page" do
     get "/"
     assert_equal 302, status
     follow_redirect!
     assert_equal "/users/sign_in", path
     assert_equal 200, status
   end
 end

编辑:以防万一它在未来有帮助。您可以使用 Warden Test Helpers用于集成测试，但上面的方法是更好的测试。这是一个工作示例:

require 'test_helper'
include Warden::Test::Helpers
class UserFlowsTest < ActionDispatch::IntegrationTest
  test "user can see home page after login" do
    @david = User.create(email: "david@mail.com", password: Devise::Encryptor.digest(User, "helloworld"))
    login_as(@david)
    get "/"
    assert_equal 200, status # User gets root_path because he loged in
    assert_equal "/", path
    logout
    get "/"
    assert_equal 302, status # User is redirected because he loged out
    Warden.test_reset! #reset Warden after each example
  end
end
