ruby-on-rails - 使用 Devise 测试成功登录

Question

我正在尝试阅读 Michael Hartl 的 RoR 教程，但这是我第三次阅读该教程，现在我正在尝试实现 Devise 而不是教程中的家庭滚动身份验证。可以想象，这有点痛苦，主要是因为 RoR 教程中的测试驱动开发与 Devise 没有很好地混合。我目前的挂断是我似乎无法成功测试成功登录。我的网站在本地主机上，所以我知道登录有效，但我的测试由于某种原因仍然失败。这是集成测试片段

def setup
  @user = users(:michael)
end

...

test "login with valid information" do
  get user_session_path
  assert_equal 200, status
  post user_session_path, 'user[email]' => @user.email, 'user[password]' => "password" 
  follow_redirect!
  assert_equal 200, status
  assert_select "a[href=?]", user_session_path, count: 0 # THIS LINE FAILS
  assert_select "a[href=?]", destroy_user_session_path
  assert_select "a[href=?]", user_path(@user)
end

我得到的错误是

FAIL["test_login_with_valid_information", UsersLoginTest, 2016-06-19 11:06:18 -0400]
test_login_with_valid_information#UsersLoginTest (1466348778.61s)
      Expected exactly 0 elements matching "a[href="/users/sign_in"]", found 1..
      Expected: 0
        Actual: 1

顶部的登录栏从 Sign in 切换而来至 Account ，所以看起来测试没有让用户在设置块中成功登录。另一个可能不相关的问题是，在我的另一个测试中，我尝试了与 post user_session_path... 完全相同的登录方法。然后检查 current_user assert_not current_user.nil? 不为空，但我收到错误

NameError: undefined local variable or method 'current_user' for #<UsersLoginTest:0x00557f81155648>

我环顾四周并确保我有正确的 devise_for :users 行在我的 routes.rb 文件中。我很确定它无法访问 current_user因为不知何故，我的集成测试无法访问 Devise 中的资源。这是我的两个问题!任何帮助将不胜感激。

编辑:我试过了

post_via_redirect user_session_path, 'user[email]' => @user.email, 'user[password]' => @user.password

而不是之前测试登录的方法，但我收到以下错误

ERROR["test_login_with_valid_information", UsersLoginTest, 2016-06-28 20:40:59 -0400]

我使用了 Jemima 建议的夹具并重新运行测试。在检查测试日志后，我发现

所以它看起来像是未经授权的？另外，我试图把 include Devise::Test::IntegrationHelpers在我的用户登录测试的顶部，但它只是抛出错误 NameError: uninitialized constant Devise::Test .

我有一个类似的问题，可能会帮助您找到答案。我相信我的装置不正确，因此 Devise 没有进行身份验证。

我的用户装置，以防它对您有帮助:

user_no_club:
  email: noclub@example.com
  encrypted_password: <%= Devise::Encryptor.digest(User, 'password') %>
  confirmed_at: 2016-01-02 08:31:23
  confirmation_sent_at: 2016-01-02 08:30:59

并且 log/test.log 显示正确的电子邮件正在通过，但是:

Completed 401 Unauthorized in 1ms (ActiveRecord: 0.0ms)

编辑:

在进一步调查中，我认为应该使用 Devise helper 来完成 Devise 集成测试。 .我无法让它工作，但我的理解来自 Google group是文档和 gem 可能暂时不同步。

编辑以下有关在单元和 Controller 中进行测试的进一步评论:

我在单元测试和 Controller 中使用 sign_in @user 并且工作正常。如下所示的 Controller 测试运行良好:

@user = users(:one)
@other_user = users(:two)
sign_in @user
get :edit, id: @other_user
assert_redirected_to root_url
