我正在努力确保使用Devise in Rails 4来维护正确的用户访问,并且我很难在测试套件中记录用户.

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,我没有做过更多的事情,只是通过适当的操作实现Devise和Users控制器.

我一直得到：NoMethodError：nil的未定义方法’env’：NilClass,特指含有sign_in @user的行,我可以找到其他人得到相同错误的实例,但似乎从来没有找到问题的实际解决方案我我试图解决.

如何使用Devise in Rails 4登录用户进行测试？谢谢.

编辑：

灯具/ users.yml里

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

解决方法

这是他们的 docs：

“Do not use Devise::TestHelpers in integration tests.”

您必须手动登录.这是一个网站测试示例,除非已登录,否则不允许用户访问根路径.您可以在支持文件中创建一种方法,手动登录用户,然后在您想要登录时调用它用户,这样您每次需要登录用户时都不必使用此代码.

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：以防万一它在将来有用.您可以使用Warden Test Helpers进行集成测试,但上述方法是更好的测试.这是一个有效的例子：

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","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
