尋找不應存在的資產路線時Rspec /水豚/硒測試失敗

Question

我正在創建一個使用jstree的rails應用程序。現在我試圖在一個rspec測試中使用capybara和selenium驅動（js：true）來測試jstree的功能。該測試是：

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 

這在shared_example，和obj爲與測試對象（在這種情況下，測量員）。我的JS樹應該產生像「_」一樣的ID的節點。所以我期待像「Surveyor_1」這樣的東西。

運行時，我收到以下錯誤：

這裏的東西雖然​​不應該擺在首位的路線。它正在尋找的資產是assets/themes/default/style.css。這是一個js-tree特定的樣式表。在測試中插入一些調試器語句，我可以驗證頁面是否有選擇器。如果頁面確實有選擇器，我只會得到異常......也就是說，如果我將have_selector的內容更改爲"BadSelector"，則測試將定期失敗（未找到選擇器）。手動查看時，js-tree功能起作用。

在此先感謝您的幫助

回聲，是誰在這裏？不，看起來像我在給自己寫信。

如果別人遇到這個問題，我確實弄清楚瞭如何解決這個問題，儘管我並不是100％確定問題的根源。當我「安裝」jstree時，我簡單地將它轉儲到資產管道（javascript）中。在開發中哪些工作正常，但沒有在測試中（見上文）。 Jstree使用它的主題插件來加載樣式表，而不是直接將它們放置在樣式表文件夾中。在測試中，無論出於何種原因，它所生成的路徑都會爲當前頁面的路徑添加前綴。我使用jstree rails gem解決了這個問題，它明確引用了用於樣式表的目錄。問題解決了。
