Rspec 功能测试混淆

Question

我有一个试图验证编辑操作的功能测试。这是一个超级简单的测试，但我写的并不多，而且我犯了一些我无法弄清楚的错误。基本上，当访问页面时，它不会呈现要编辑的文本信息，并且“更新”按钮不存在。为了清楚起见，这是我的错误和代码。

测试

scenario "Staff can edit the response messages" do
  group = Group.create!(name: "Group A", response: "You are now subscribed for updates")
  visit "/groups/#{group.id}/edit"

  user = FactoryGirl.create(:user)
  fill_in "Email", with: user.email
  fill_in "Password", with: user.password
  click_button "Sign in"

  expect(page).to have_content("You are now subscribed for updates")
end

查看

 <div class="container text-center">
  <div class="row">
  <div class="col-lg-8 col-lg-offset-2 well">
     <%= form_for @group do |form| %>
       <div class="form-group">
         <%= form.label :body, "Edit The Response:", class: "message_label"%>
         <%= form.text_field :response, class: "form-control", placeholder: "New things are happening!" %>
       </div>
       <%= form.submit "Update", class: "btn btn-primary" %>
    <% end %>
  </div>
 </div>
</div>

更奇怪的是，当我运行“save_and_open_page”时，我期望的内容是存在的？但是，我的测试仍然失败，说没有显示预期的内容很奇怪！

Answer 1

据我所知，问题是：

1. 测试运行visit
2. fill_in 预计页面已加载

第二个期望可能是错误的，您必须等待页面加载，要么使用魔法 sleep 2 手动加载，要么使用任何水豚的 finder/expectation 自动加载

您的测试可能如下所示：

  group = Group.create!(name: "Group A", response: "You are now subscribed for updates")
  user = FactoryGirl.create(:user)

  visit "/groups/#{group.id}/edit"
  // <= check any static text to ensure the page is loaded
  // expect will wait for a defailt timeout ~ 2 seconds
  expect(page).to have_content("Tulim time text")

  fill_in "Email", with: user.email

  // ...

手动延迟示例

  visit "/groups/#{group.id}/edit"
  // wait a few seconds for page loading
  sleep 5
  fill_in "Email", with: user.email
