Capybara::ElementNotFound 远程 true 问题

Question

我有一个要使用 remote=>true

提交的表单

<%= form_tag fetch_data_path, :remote => true do %> 
    Date: <%= text_field_tag :date %>
    Amount:<%= text_field_tag :amount %>
    From:<%= text_field_tag :from %>
    To:<%= text_field_tag :to %>

 <%= submit_tag "Convert"%> &nbsp;

<% end %>


<span style="font-weight: bold;">Converted Amount:</span> 
<div id="converted_amount"></div>

提交表单时，转换后的值显示在 div 中，id 为

#converted_amount

这是我的 rspec:

RSpec.feature "User performs exchange", :type => :feature do
  scenario "with valid input" do
    visit exchanges_path
    fill_in 'date', :with => "2017-08-24"
    fill_in 'amount', :with => "100"
    fill_in 'from', :with => "pound"
    fill_in 'to', :with => "dollar"
    click_button('Convert')

    expect(page).to have_text("Converted Amount:")
  end
end

问题是当我运行它时，我得到

Capybara::ElementNotFound: Unable to find xpath "/html" and yet when I comment out click_button, it works.

我做错了什么？

Answer 1

这是我的解决方案：

我将以下 gem 添加到我的 Gemfile

  gem 'capybara-webkit'
  gem 'selenium-webdriver'

然后将 :js => true 添加到我的规范文件中。变成了：

RSpec.feature "User performs exchange", :type => :feature do
  scenario "with valid input", :js => true do
    visit exchanges_path
    fill_in 'date', :with => "2017-08-24"
    fill_in 'amount', :with => "100"
    fill_in 'from', :with => "pound"
    fill_in 'to', :with => "dollar"
    click_button('Convert')

    expect(page).to have_text("Converted Amount:")
  end
end
