WPF CodedUI測試：以編程方式啓動應用程序

如果我記錄要在登錄憑據中輸入對話框的操作，並在UImap1.uitests中調用此Submit（）。自動生成的代碼會是這個樣子：WPF CodedUI測試：以編程方式啓動應用程序

public void Launch() 
    { 
     #region Variable Declarations 
     WpfEdit uIUsernameBoxEdit = this.UIOCC600OILoginWindow.UIUsernameBoxEdit; 
     WpfEdit uIPasswordBoxEdit = this.UIOCC600OILoginWindow.UIPasswordBoxEdit; 
     WpfButton uIOKButton = this.UIOCC600OILoginWindow.UIOKButton; 
     #endregion 

     // Type 'username' in 'usernameBox' text box 
     uIUsernameBoxEdit.Text = this.LaunchParams.UIUsernameBoxEditText; 

     // Click 'passwordBox' text box 
     Mouse.Click(uIPasswordBoxEdit, new Point(63, 13)); 

     // Type '********' in 'passwordBox' text box 
     Keyboard.SendKeys(uIPasswordBoxEdit, this.LaunchParams.UIPasswordBoxEditSendKeys, true); 

     // Click 'OK' button 
     Mouse.Click(uIOKButton, new Point(33, 14)); 
    }

現在，如果我手動啓動在我CodedUI測試類在我的ClassInitialize decorded的方法下的應用程序如下：

 [ClassInitialize()] 
     public static void MyTestInitialize(TestContext context) 
     { 
      Process.Start(@"C:\Program Files (x86)\MyCompany\MyApp.exe"); 
      Playback.Wait(2000); 

      var uimap = new LaunchApplicationMap(); 
      var loginParams = uimap.EnterLoginCredentialsParams; 
      loginParams.UIUsernameBoxEditText = "username"; 
      loginParams.UIPasswordBoxEditSendKeys = Playback.EncryptText("password 
"); 
      uimap.Launch(); 
      Playback.Wait(5000); 
     }

爲什麼我如下所示得到下面的空例外？

enter image description here

這也是堆棧跟蹤：

    Message=Object reference not set to an instance of an object.

    InnerException:

TIA。

您需要初始化播放引擎以在測試方法之外使用CodedUI。該框架會自動初始化testinitalize/cleanup方法中的播放/清理，因此您不會在那裏看到它。

ClassInitialize/AssemblyInitialize發生在任何測試開始之前，因此您必須調用Playback.Initialize（）。

非常感謝。在這裏給我節省了一些痛苦。 –
