Question

我是Ruby / Rails的新手，尤其是Capybara和整个过程，所以请耐心等待，因为我已经花了很多时间在这上面，我终于决定问，因为我确定它是一些简单的东西，我只是还没有意识到。

所以我有一个表单，其中有几个复选框，用于过滤显示的结果（即，您选择一个或多个并提交并重新加载页面，并过滤列表）。在我的功能文件中，我有以下场景（提交表单的按钮有一个值=“刷新”）：

Scenario: no ratings selected
  When I uncheck the following ratings: G, PG, PG-13, NC-17, R
  And I press "Refresh"
  Then show me the page
  And I should see none of the movies

Scenario: all ratings selected
  When I check the following ratings: G, PG, PG-13, NC-17, R
  And I press "Refresh"
  Then show me the page
  And I should see all of the movies

当我使用rake功能运行时，它会提供以下输出：

    And I press "Refresh"                                        #     features/step_definitions/web_steps.rb:61
xprop:  unable to open display ''

我在场景中稍后使用了page.body，我相信这就是我接下来会出现以下错误的原因：

以下是相关的步骤定义

When /I (un)?check the following ratings: (.*)/ do |unc, rating_list|
  rating_list.split(", ").each do |r|
    if(unc)
      uncheck("ratings_#{r}")
    else
      check("ratings_#{r}")
    end
  end
  assert true, "Implemented checking function"
end


Then /I should (not )?see movies with the following ratings: (.*)/ do |nt, rating_list|
  flag = true
  rating_list.split(", ").each do |r|
    if(nt)
      if(page.body =~ /<td>#{r}/)
        flag = false;
      end
    else
      if(page.body !~ /<td>#{r}/)
        flag = false
      end
    end
  end
  assert flag, "Seeing (or not) movies of ratings list - implemented"
end


Then /I should see all of the movies/ do
  tot = Movie.all.count
  assert page.have_selector('tbody tr', :count => tot)
end


Then /I should see none of the movies/ do
  num = page.body.scan(/00:00:00 UTC/m).length
  assert size == 0, "Showing no movies - implemented"
end



When /^(?:|I )press "([^"]*)"$/ do |button|
  click_button(button)
end

Then /^show me the page$/ do
  save_and_open_page
end

我有时间研究我有时间并且有很多我不知道的事情。任何帮助或见解将不胜感激。谢谢！

您的问题是您没有安装任何浏览器来处理html文件。您似乎正在使用无头服务器（没有X），因此您的系统正在尝试找到一个合适的浏览器（可以从命令行运行）。

查看Capybara drivers并选择合适的一个。
