單元測試與模板golang

我有服務模板about.html單元測試與模板golang

func AboutPage(w http.ResponseWriter, r *http.Request, ps httprouter.Params) { 
    template, err := template.ParseFiles("templates/about.html") 

    if err != nil { 
      logfile.ErrorMsg(fmt.Sprint(err.Error())) 
      http.Error(w, err.Error(), http.StatusInternalServerError) 
      return 
     } 


    template.Execute(w, nil) 
}

它工作正常，但一個很簡單的HTTP處理程序時，我要運行這個單元測試：

func getRequest(t testing.TB, url string) *http.Request { 
    req, err := http.NewRequest("GET", url, nil) 
    if err != nil { 
     t.Fatal(err) 
    } 
    return req 
} 

func TestAboutPage(t *testing.T) { 
    r := getRequest(t, "/about") 

    rw := httptest.NewRecorder() 

    AboutPage(rw, r, httprouter.Params{}) 

}

程序崩潰，這樣的：

如果我用一個簡單的替換fprintf中template.execute（）（W，「富」）試運行網絡東北。那麼如何用模板完成單元測試？

也許這是包和變量名之間的衝突。嘗試將變量從「模板」更改爲「t」，例如't，err：= template.ParseFiles（「templates/about.html」）... t.Execute（w，nil）'。 –

同樣的結果。它必須與template.execute完全相關。 – stihl

您使用的是哪個版本的Go？我在go1.7.1上運行你的代碼，一切正常。 – danbondd

好吧，我想我想通了，我使用

_ "github.com/mattn/go-sqlite3"

爲進口。我跑去安裝在該目錄中，現在它運行...

這將是我的下一個問題 - 我很高興你把它分類！ – danbondd
