Ruby on rails rspec特性测试未找到模态输入

我有一个rspec测试，它试图在弹出模式表单中填充一个字段。相关线路为

fill_in 'Name', with: 'Jo Blo'

错误消息是

Capybara::ElementNotFound:
       Unable to find visible field "Name" that is not disabled

这意味着它正在查找字段，但将其视为已禁用。但是，如果在出现故障时使用capybara屏幕截图查看页面，则该字段可见，并且该字段的html为

<div class="field">
        <label for="user_name">Name</label><sup>*</sup><br>
        <input type="text" name="user[name]" id="user_name">
</div>

错误消息变为

    Failure/Error: expect(page).to have_css '#modal_new_user'
           expected to find visible css "#modal_new_user" but there were no 

matches. Also found "", which matched the selector but not all filters.

这似乎意味着找不到模式，但再次，如果我查看水豚的屏幕截图，模式的html是可见的。 我该如何解决这个问题

我使用的是capybara 3.0.2和rspec rails 3.7.2

引导模式的代码是

 <div id='modal_new_user' class="modal fade">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
          <h4 class="modal-title">Warning</h4>
          <p>enter code here Right now there is a 10 day free trial. Just fill in the form below.</p>
      </div>
      <div class="modal-body">
    <form class="edit_user" id="edit_user_12004" action="/users" accept-charset="UTF-8" method="post"><input name="utf8" type="hidden" value="&#x2713;" /><input type="hidden" name="authenticity_token" value="306T/5kB9pqb9sW6mdW+tXyCzfydEF2tf8wQMJXEICO5uQ/YEDVVYqg12l7Qe+lU4uELZy/d1VIhzZObk/FVcQ==" />

      <div class="field">
        <label for="user_name">Name</label><sup>*</sup><br />
        <input type="text" name="user[name]" id="user_name" />
      </div>
      <div class="field">
        <label for="user_email">Email</label><sup>*</sup><br />
        <input type="email" name="user[email]" id="user_email" />
      </div>
      <div class="field">
        <label for="user_password">Password</label><sup>*</sup><br />
        <input type="password" name="user[password]" id="user_password" />
      </div>

结果是测试有

type:：system

，所以当我删除它时，测试通过了。如果puma.rb指定了并发性，那么rails系统测试似乎会出现问题。

实际包含的HTML是什么？“找不到可见字段”名称“未禁用”并不意味着is看到字段“名称”，而是意味着它已禁用，这意味着它要么没有看到字段，要么确实看到字段，但它已禁用-对错误的理解不要超过它的状态。这可能是一个时间问题。你必须记住，水豚开始以极快的速度点击东西，这通常是在JS完成之前。尝试使用

find（'#modal_new_user'）。在（'Name'，中填入：'Jo Blo'）

，因为这将等待元素出现。@max

fill_in

本身也将等待匹配的元素（最长为Capybara.default_max_wait_time seconds），因为它实现为

find（…）。set（…）

我有Capybara.default\u max\u wait\u time=5。我已经为模式添加了代码。
