Question

这是我第一次尝试Capybara，我似乎无法找到为什么它找不到我的表单元素。

每当我尝试找到表单元素时，

When /^they submit a resolution in Markdown$/ do
  visit "/resolutions/new"
  fill_in "title", :with => "Title"
  fill_in "libelle", :with => "Some text here\n\nNew paragraph"
  click_button "Submit"
end

它不知道它在哪里，

Scenario: Submission of a resolution                 # features/resolutions.feature:5
    Given the user is a member                       # features/step_definitions/user_steps.rb:26
    When they submit a resolution in Markdown        # features/step_definitions/resolution_steps.rb:8
      cannot fill in, no text field, text area or password field with id, name, or label 'title' found (Capybara::ElementNotFound)
      (eval):2:in `fill_in'
      ./features/step_definitions/resolution_steps.rb:10:in `/^they submit a resolution in Markdown$/'
      features/resolutions.feature:7:in `When they submit a resolution in Markdown'

即使它出现在页面上

<%= form_for(@resolution) do |f| %>
  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :libelle %><br />
    <%= f.text_area :libelle %>
  </div>
  <div class="actions">
    <%= f.submit "Submit" %>
  </div>
<% end %>

它似乎已正确呈现。

看起来很明显，但我找不到它。我找到了this question，但答案毫无用处。即使在审核the Devise+Cucumber example app之后，我也找不到错误。

这对我和我的测试造成了伤害。有什么想法吗？

Answer 1

尝试在puts page.body之后添加visit "/resolutions/new"，并查看堆栈跟踪告诉您的内容。您将能够看到表单字段的ID。例如，虽然我的一个列名为“name”，但渲染的html中的id是“user_name”。

Answer 2

我遇到了类似的问题，事实证明我需要做的是将“id：”字段添加到表单元素本身。

例如，您有：

<div class="field">
  <%= f.label :title %><br />
  <%= f.text_field :title %>
</div>

但是如果你把它改成：

<div class="field">
  <%= f.label :title %><br />
  <%= f.text_field :title, id:"title" %>
</div>

请注意，我在text_field元素上添加了一个“id”字段。我不确定为什么Capybara没有找到标签，但这对我有用。希望它可以帮助你（或其他人）。

Answer 3

这是一个疯狂的猜测，但我认为你需要等待。不确定'fill_in'是否等待页面可用。我知道'find'会自动等待。

尝试增加

Capybara.default_wait_time

Answer 4

如果您的Rails视图如下所示：

<%= form.text_field :first_name %>

尝试通过将第一部分大写后跟空格然后小写其余部分来调用元素。

fill_in "First name", with: 'Elaine'

这应该这样做，不需要id属性。
