黄瓜、水豚和 ElementNotFound

Question

在我的 Rails 应用程序中，我有一个带有执行 javascript 函数的链接的页面：

<%= link_to_function("Add an address", "add_fields(this)".html_safe) %>

在我的黄瓜功能中，我有：

And I press "Add an address"

我得到的消息是：

Capybara::ElementNotFound: no button with value or id or text 'Add an address' found

我可能丢失了一些东西，但我找不到它是什么..

Answer 1

您应该执行以下操作中的一项且仅执行一项：

• 将提交按钮重命名为“创建”
• 将测试更改为“然后我按“保存””

• 向您的按钮添加一个 id，并更改测试，例如这个：

  查看
  = f.submit '保存', :id => :foo

  测试
  我按“foo”

由 joaomilho 解决：

您应该执行以下操作中的一项且仅执行一项：

将提交按钮重命名为“创建”
将您的测试更改为“然后我按“保存””
向按钮添加一个 id，并更改测试，如下所示

：
= f.submit '保存', :id => ：foo

测试
我按“foo”

这里有同样的行为，我正在使用：

Rails 3 Cucumber/Capybara/Haml

Feature: Manage posts
  In order to [goal]
  [stakeholder]
  wants [behaviour]

  @wip
  Scenario: Register new post             # features/manage_posts.feature:6
    Given I am on the new post page       # features/step_definitions/web_steps.rb:19
    When I fill in "Title" with "title 1" # features/step_definitions/web_steps.rb:40
    And I fill in "Body" with "body 1"    # features/step_definitions/web_steps.rb:40
    And I uncheck "Published"             # features/step_definitions/web_steps.rb:83
    And I press "Create"                  # features/step_definitions/web_steps.rb:27     
    Then I should see "title 1"           # features/step_definitions/web_steps.rb:108
    And I should see "body 1"             # features/step_definitions/web_steps.rb:108
    And I should see "false"              # features/step_definitions/web_steps.rb:108

步骤：

When /^(?:|I )press "([^"]*)"(?: within "([^"]*)")?$/ do |button, selector|   with_scope(selector) do
    click_button(button)
    selenium.wait_for_page_to_load   
    end  
end

查看新内容：

%h1 New post

= render 'form'

= link_to 'Back', posts_path

错误：

 no button with value or id or text 'Create' found (Capybara::ElementNotFound)
      ./features/step_definitions/web_steps.rb:29
      ./features/step_definitions/web_steps.rb:14:in `with_scope'
      ./features/step_definitions/web_steps.rb:28:in `/^(?:|I )press "([^"]*)"(?: within "([^"]*)")?$/'
      features/manage_posts.feature:11:in `And I press "Create"'

_form：

= form_for @post do |f| 
  -if @post.errors.any?
    #errorExplanation
      %h2= "#{pluralize(@post.errors.count, "error")} prohibited this post from being saved:"
      %ul 
        - @post.errors.full_messages.each do |msg|
          %li= msg 

  .field
    = f.label :title
    = f.text_field :title
  .field
    = f.label :body
    = f.text_area :body
  .field
    = f.label :published
    = f.check_box :published
  .actions
    = f.submit 'Save'

Answer 3

我相信你想要

And I follow "Add an Address"

Answer 4

Sebastian：尝试向您的链接添加一个 ID，并在测试中引用它。

Answer 5

最初的问题不是您创建链接但尝试按按钮吗？

仔细阅读水豚文档，你会发现方法是不同的。
