測試連接UploadedFile的形成與PhpSpec

Question

我試圖測試圖片進口商這需要一個文件，並提交一個表單附有該圖像提交。測試的那部分似乎是它摔倒的部分，我不知道如何解決它。

我明白「不嘲笑你不擁有的東西」的概念，但是如果不承認對私有方法insertImageThroughForm的調用，則測試不起作用。

我得到以下錯誤：

75 ! imports image assets 
     method call: 
      - submit(["file" => ["assetFile" => ["file" => Symfony\Component\HttpFoundation\File\UploadedFile:0000000027d380bc00007f8c6cad27ec Object (

      'originalName' => 'picco.jpg' 
      'mimeType' => 'application/octet-stream' 
      'size' => null 
      'error' => 0 
     )]]], false)

什麼你正在測試超過一個單元測試的集成測試。 PhpSpec不適用於集成測試，但僅適用於低單元測試。爲什麼這是一個集成測試？因爲你使用一個真正的文件系統，它是外部服務，也可以幾個第三方庫像Filesystem和Finder。

您試圖模擬Finder，但Finder在該方法中直接初始化，因此無法模擬。您需要注入Finder作爲該類的依賴項。
