行动邮递员

def welcome_send(user)
        @user = user
        mail to: user.email, subject: 'Welcome to my site', from: 'suhasmv29@gmail.com'
    end

用于验证邮件已发送的 RSpec 测试用例

it "sends a confirmation email" do
      expect { mail.to }.to change { ActionMailer::Base.deliveries.count }.by(1)
    end

错误

expected `ActionMailer::Base.deliveries.count` to have changed by 1, but was changed by 0

我有回调名称authenticate_admin_user。如果当前用户电子邮件 ID 为“adminuser@admin.com”，则返回 true

def authenticate_admin_user!
 if Current.user.blank? || Current.user.email != "adminuser@admin.com"
  redirect_to courses_path, danger: "Admin login required" 
 end 
end

当我调用 new action 时，此回调将运行。在测试新操作时，我必须设置 Current.user 值

describe "GET /new" do
    describe "Create course with admin login"
      it "will not renders a new course page" do
        get new_course_url
        expect(response).to_not be_successful
      end
      it "will render a new course page" do
        get new_course_url
        expect(response).to be_successful
      end
  end

如何设置Current.user的值？PS：这里 Current 是一个 ActiveSupport::Currentattributes 模型，而 user 是 Current 类中的一个属性。

我们可以检查enqueued_jobs.length，前提是电子邮件是唯一可能的后台作业类型。

it 'sends exactly one, particular email' do
  expect { post :create }.to(
    # First, we can check about the particular email we care about.
    have_enqueued_mail(MyMailer, :my_particular_email)
  )

  # But we also have to check that no other email was sent.
  expect(ActiveJob::Base.queue_adapter.enqueued_jobs.length).to eq(1)
end

有没有更好的方法来断言：

1. MyMailer.my_particular_email已排队，
2. 没有其他电子邮件排队，
3. 我们不关心其他非电子邮件后台作业是否已排队

我正在做第10章的Michael Hartl的Rails Tutorial截屏视频+在线书籍,我被困在Destroying User的最后一章子.

控制台输出:

我是新手在Rails应用程序中使用RSpec而我无法让RSpec看到我的模型:(

我在我的文章中添加了以下几行 Gemfile

group :development, :test do
  gem 'rspec-rails'
end

并安装它

rails generate rspec::install

然后我facebook_page.rb在app/models/目录中创建了一个文件,它不是 ActiveModel

class FacebookPage
  class << self
    # define class variables
    attr_accessor :app_id
    attr_accessor :app_secret
  end
end

现在我正在尝试测试它,所以我添加了一个facebook_page_spec.rbin spec/models/目录

describe FacebookPage do
  describe ".app_id" do
    it "should return the FB_APP_ID environment variable and thus not be null" do
      FacebookPage.app_id.should_not be_empty 
    end
  end
end

但是当我跑步的时候

bundle exec rake spec

我收到以下错误:

/home/geoffroy/.rvm/rubies/ruby-1.9.3-p194/bin/ruby -S rspec ./spec/models/facebook_page_spec.rb
/home/geoffroy/dev/mybandpage/spec/models/facebook_page_spec.rb:1:in `<top (required)>': uninitialized constant …

我写了*simple_form*输入扩展名,位于app/inputs/something_input.rb中

我正在尝试为此编写RSpec.当我把这个规范放在spec/helpers/application_helper_spec.rb中时,一切正常,没有任何问题.

# spec/helpers/application_helper_spec.rb
require 'spec_helper'
describe ApplicationHelper do
  it do
    helper.simple_form_for @foo,:method=>'get', :url=>helper.users_path do |f|
      f.input :created_at, :as =>:custom_datepicker
    end.should =~ /something/
  end
end

现在我正在尝试将该规范移动到spec/inputs/something_input_spec.rb,因此它将是类似的名称路径.

# spec/imputs/something_input_spec.rb
require 'spec_helper'
describe SomethingInput do
  it do
    helper.simple_form_for @foo,:method=>'get', :url=>helper.users_path do |f|
      f.input :created_at, :as =>:custom_datepicker
    end.should =~ /something/
  end
end
#
#ERROR:   undefined local variable or method `helper' for #<RSpec::Core::ExampleGroup

我想告诉RSpec威胁这个文件作为类型帮助规范,所以我将使用所有RSpec :: Rails :: HelperExampleGroup功能的辅助方法

... 我怎样才能做到这一点 ？？

我试图用RSpec …

我有一个rspec测试失败,但在开发中,当我自己执行操作时,页面呈现正确.

这是片段:

describe "sign up process" do

let (:admin1) { FactoryGirl.create(:admin) }

describe "with valid information"

  before do 
    visit new_admin_registration_path
    fill_in "Email", with: admin1.email
    fill_in "Password", with: admin1.password
    fill_in "Password confirmation", with: admin1.password_confirmation
    click_button "Sign up"
  end

  it { should have_selector('div.alert') }
end

根本没有找到那个选择器,但我确认它在使用开发环境查看源时存在.

我希望能够做的是检查正在渲染的页面以查看我缺少的内容.有没有办法做到这一点？

我有一个功能规格,如spec/features/awesome_feature_spec.rb需要spec/shared_examples/awesome_spec.rb.后者包含我正在使用的所有shared_examples awesome_feature_spec.rb.当一个示例失败并且我编辑一个文件来修复它并保存它时,guard会尝试再次运行该示例,但它会直接运行awesome_feature.rb而不是awesome_feature_spec.rb因为失败的共享示例所在awesome_feature.rb.这当然会导致错误,因为它需要运行awesome_feature_spec.rb,这是实际的功能规范.

这就是我的Guardfile的样子:

guard :rspec do
  watch(%r{^spec/.+_spec\.rb$})
  watch(%r{^lib/(.+)\.rb$})     { |m| "spec/lib/#{m[1]}_spec.rb" }
  watch('spec/spec_helper.rb')  { "spec" }

  # Rails example
  watch(%r{^app/(.+)\.rb$})                           { |m| "spec/#{m[1]}_spec.rb" }
  watch(%r{^app/(.*)(\.erb|\.haml|\.slim)$})          { |m| "spec/#{m[1]}#{m[2]}_spec.rb" }
  watch(%r{^app/controllers/(.+)_(controller)\.rb$})  { |m| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
  watch(%r{^spec/support/(.+)\.rb$})                  { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }

  # Capybara features specs
  watch(%r{^app/views/(.+)/.*\.(erb|haml|slim)$})     { |m| "spec/features/#{m[1]}_spec.rb" }
  watch(%r{^spec/shared_examples.*/(.+)\.rb$})      { |m| "spec/features/#{m[1]}_spec.rb" }

  # Turnip features and steps …

我对rails很新,还在学习它.现在我得到了这样的测试失败消息:

1) LayoutLinks should have the right links on the layout
 Failure/Error: click_link("Help")
 Capybara::Ambiguous:
   Ambiguous match, found 2 elements matching link "Help"
 # ./spec/requests/layout_links_spec.rb:47:in `block (2 levels) in <top (required)>'

因为我在我的主页上有两个相同的"帮助"链接,但似乎测试认为这是一个模糊的匹配,我希望它以相同的方式测试它们,因为链接指向同一页面.

实际上网站上有几种解决方案,但由于我很新,所以大多数解决方案都很复杂,所以有人能给我最简单的解决方案吗？提前致谢.

更新:

在我的观点和规范中没有什么复杂的.我还在学习一切.

这是我的规格

        visit root_path
        expect(page).to have_title("Home")      
        click_link("About")
        expect(page).to have_title("About")
        click_link("Contact")
        expect(page).to have_title("Contact")
        click_link("Help")
        expect(page).to have_title("Help")

这是我的标题部分在布局中

<header>
  <nav class="round">
    <ul>
        <li><%= link_to "Home", root_path %></li>
        <li><%= link_to "Help", help_path %></li>
        <li><%= link_to "Sign in", "#" %></li>
    </ul>
  </nav>
</header>

这是我的页脚部分布局

<footer>
  <nav class="round">
    <ul>
        <li><%= link_to "About", …

我有以下文件夹结构:

app
??? assets
??? controllers
??? helpers
??? mailers
??? market_adapters
?   ??? german.rb
?...

该文件market_adapters/german.rb是:

module MarketAdapters #(I've also tried naming it singular)
   class German
   end
end

运行测试时,我收到错误:

/gems/activesupport-5.0.0/lib/active_support/dependencies.rb:512:in
`load_missing_constant': Unable to autoload constant German, 
expected .../app/market_adapters/german.rb to define it (LoadError)

添加market_adapters文件夹autoload_paths似乎没有任何效果config.autoload_paths << "#{Rails.root}/app/market_adapters"

如果我移动market_adapters到lib文件夹,一切正常.但仍然想拥有它app,任何想法？

顺便说一下,我正在使用Rails 5.
