寻找不应存在的资产路线时Rspec /水豚/硒测试失败

Question

我正在创建一个使用jstree的rails应用程序。现在我试图在一个rspec测试中使用capybara和selenium驱动（js：true）来测试jstree的功能。该测试是：

scenario "the object associated with the data-pane is selected in the tree", js: true do 
    visit surveyor_path 
    using_wait_time(20) { expect(page).to have_selector("##{obj.class.name}_#{obj.id.to_s}") } 
end 

这在shared_example，和obj为与测试对象（在这种情况下，测量员）。我的JS树应该产生像“_”一样的ID的节点。所以我期待像“Surveyor_1”这样的东西。

运行时，我收到以下错误：

Failure/Error: Unable to find matching line from backtrace

     No route matches [GET] "/surveyors/themes/default/style.css"

这里的东西虽然​​不应该摆在首位的路线。它正在寻找的资产是assets/themes/default/style.css。这是一个js-tree特定的样式表。在测试中插入一些调试器语句，我可以验证页面是否有选择器。如果页面确实有选择器，我只会得到异常......也就是说，如果我将have_selector的内容更改为"BadSelector"，则测试将定期失败（未找到选择器）。手动查看时，js-tree功能起作用。

在此先感谢您的帮助

回声，是谁在这里？不，看起来像我在给自己写信。

如果别人遇到这个问题，我确实弄清楚了如何解决这个问题，尽管我并不是100％确定问题的根源。当我“安装”jstree时，我简单地将它转储到资产管道（javascript）中。在开发中哪些工作正常，但没有在测试中（见上文）。 Jstree使用它的主题插件来加载样式表，而不是直接将它们放置在样式表文件夹中。在测试中，无论出于何种原因，它所生成的路径都会为当前页面的路径添加前缀。我使用jstree rails gem解决了这个问题，它明确引用了用于样式表的目录。问题解决了。
