水豚没有找到表格元素

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格元素。

每次我试图找到一个表单元素，

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

它似乎已正确呈现。

这似乎是显而易见的，但我找不到它。 我找到了这个问题 ，但答案却毫无用处。 即使在查看了Devise + Cucumber示例应用程序之后 ，我也找不到有什么问题。

这对我和我的测试造成了伤害。 有任何想法吗？

Answer 1

尝试在visit "/resolutions/new"后添加puts page.body ，看看你的堆栈跟踪告诉你什么。 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certificate我需要做的是将“id：”字段添加到表单元素本身。

例如，您有：

 
 <%= f.label :title %>
 <%= f.text_field :title %>  

但是如果你改成它：

 
 <%= f.label :title %>
 <%= f.text_field :title, id:"title" %>  

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。
