單元測試框架：在新進程中運行測試

我編寫了一個使用Unit testing framework的GUI應用程序。該應用程序在樹視圖中顯示所有找到的單元測試。如果您單擊單元測試名稱，程序將運行此測試並顯示結果。它的工作原理！單元測試框架：在新進程中運行測試

但是現在我希望每個測試用例都運行在一個新的進程中。我創建了一個「工作線程」（帶有模塊線程），但是此線程也在同一進程中運行。

模塊「multiprocessing」是解決方案，但我遇到了問題，我的實施。我把我的「測試執行代碼」在自己的功能和嘗試：

item = self.GetSelection() 
name = self.GetItemText(item) 
p = multiprocessing.Process(target=ExecuteTest, args=(name, item)) 
p.daemon = True 
p.start()

但後來我得到了錯誤。

有沒有人有什麼想法？

顯然，你試圖「醃製」一些不可取的東西（似乎是一個wx對象）。嘗試僅用作參數「簡單」對象（即沒有圖形對象），它應該工作得更好。您也可以看看python nose unitest庫，它允許您自動運行多進程中的測試。

使用fork產生子進程。這將需要你的一些工作，但會起作用。

作爲說明：multiprocessnig模塊是使用fork實現的。

更新：你的代碼仔細看後似乎item viariable不與pickle（就是一個字？）。我不認爲你需要它，因爲你可以用簡單的東西（一個值或某種類型）代替它。

「pickleable（這是一個詞？）」，那麼'pythonic'呢？或'voooooooooooom' – SingleNegationElimination

我建議您創建一個運行測試的單獨腳本，然後您可以使用subprocess模塊調用該腳本，併爲其提供要運行的測試的名稱。

好處是，您可以在持續集成服務器，每晚構建或其他不需要GUI的批處理類型進程中使用同一腳本。
