Question

我目前正在关注作者Michael Hartl的Ruby on Rails教程。我陷入了第10.1.4章，其中测试应该是绿色，但目前是RED，这是错误信息：

Started with run options --seed 48963

 FAIL["test_valid_signup_information_with_account_activation", UsersSignupTest, 1.7533403700217605]
 test_valid_signup_information_with_account_activation#UsersSignupTest (1.75s)
        Failed assertion, no message given.
        test/integration/users_signup_test.rb:44:in `block in <class:UsersSignupTest>'

  41/41: [=========================================================================================================] 100% Time: 00:00:01, Time: 00:00:01

Finished in 1.78481s
41 tests, 173 assertions, 1 failures, 0 errors, 0 skips

这是包含主要错误（FAIL）的文件，根据报告应该是'断言user.reload.activated？'：

require 'test_helper'

class UsersSignupTest < ActionDispatch::IntegrationTest

  def setup
    ActionMailer::Base.deliveries.clear
  end

  test "invalid signup information" do
    get signup_path
    assert_no_difference 'User.count' do
      post users_path, user: { name:  "",
                               email: "user@invalid",
                               password:              "foo",
                               password_confirmation: "bar" }
    end
    assert_template 'users/new'
    assert_select 'div#error_explanation'
    assert_select 'div.alert.alert-danger'
  end

  test "valid signup information with account activation" do
    get signup_path
    assert_difference 'User.count', 1 do
      post users_path, user: { name:  "Example User",
                               email: "user@example.com",
                               password:              "password",
                               password_confirmation: "password" }
    end
    assert_equal 1, ActionMailer::Base.deliveries.size
    user = assigns(:user)
    assert_not user.activated?

    log_in_as(user)

    get edit_account_activation_path(user.activation_token, email: 'wrong')
    assert_not is_logged_in?

    assert user.reload.activated?

如果有人能帮助我解决这个问题，我将不胜感激，这将为我节省宝贵的时间。

Answer 1

我认为问题归结为这两行：

assert_select 'div#<error_explanation>'
assert_select 'div.<alert alert-danger>'

这些必须是错误中概述的有效CSS选择器。他们不是。固定版本可能是：

assert_select 'div#error_explanation'
assert_select 'div.alert.alert-danger'

这取决于你的风格。记住这些工作就像jQuery一样，所以它们类似于$('div#error_explanation')。

您的测试本身看起来很好，但是当您在尝试编辑其帐户激活信息时断言用户实际已被激活时，它们似乎会失败：

get edit_account_activation_path(user.activation_token, email: user.email)
assert user.reload.activated? # <= test fails here

在您的回购邮件的account_activations_controller.rb文件中，您有：

def edit
  user = User.find_by(email: params[:email])
  if user && !user.activated? && user.authenticated?(:activation, params[:id])
    user.activate # <= here's where you're activating the user
    log_in user
    flash[:success] = "Account activated!"
    redirect_to user
  else
    flash[:danger] = "Invalid activation link"
    redirect_to root_url
  end
end

但是，查看您的user.rb类，看起来您实际上完全错过了activate方法（遗憾的是错误消息似乎没有向您表明这一点）。因此，请将以下方法添加到User模型中，然后再次尝试运行规范：

def activate
  update_columns(activated: true, activated_at: Time.current)
end

修改

在the point where your tests went red检出您的回购后，我现在可以看到此问题出在您的SessionsHelper#redirect_back_or方法中：

def redirect_back_or(default) redirect_to(session[:forwarding_url] || default) session.delete[:forwarding_url] end

session.delete[:forwarding_url]应该是session.delete(:forwarding_url)，括号而不是方括号。
