Capybara 找不到字体真棒图标答案

【问题描述】：

这是我正在尝试运行的功能规范。 Capybara似乎忽略了字体真棒图标...... 在我的索引中，管理员可以通过单击垃圾桶图标来删除任何视频。非常感谢您的帮助

我正在测试的索引

    <%= link_to video_path(video), method: :delete, data: {confirm: "Are you sure?"}  do %>
      <i class="fas fa-trash-alt trash"></i>
   <% end %>

Rspec测试是红色的

scenario "delete a video" do
  video_1 =  Video.create(url: "https://www.youtube.com/watch?v=oWYKTiqPvYA&tg")
  video_2 =  Video.create(url: "https://www.youtube.com/watch?v=UxIPVAPRBi4")

 visit videos_path

 first(:link, '.i.fas.fa-trash-alt.trash').click

 expect(page).to have_content("Video was successfully destroyed")
end

如果我在i 标签之间添加文本delete：<i class="fas fa-trash-alt trash">delete</i>

Rspec测试是绿色的

scenario "delete a video" do
  video_1 =  Video.create(url: "https://www.youtube.com/watch?v=oWYKTiqPvYA&t")
  video_2 =  Video.create(url: "https://www.youtube.com/watch?v=UxIPVAPRBi4")

 visit videos_path

 first(:link, 'delete').click

 expect(page).to have_content("Video was successfully destroyed")
end

我使用了save_and_open_page，但图标没有出现

【解决方案1】：

终于找到了解决办法：我在我的 link_to 中添加了一个类

<%= link_to video_path(video), method: :delete, data: {confirm: "Are you sure?"}, class: "delete_link"  do %>
  <i class="fas fa-trash-alt trash"></i>
<% end %>

这样它是绿色的：

scenario "delete a video" do
    video_1 =  Video.create(url: "https://www.youtube.com/watch?v=Yozj4ZB98Gg")
    video_2 =  Video.create(url: "https://www.youtube.com/watch?v=UxIPVAPRBi4")

    visit videos_path

    first(:css, ".delete_link").click

    expect(page).to have_content("Video was successfully destroyed")
end
