WPF CodedUI测试：以编程方式启动应用程序

如果我记录要在登录凭据中输入对话框的操作，并在UImap1.uitests中调用此Submit（）。自动生成的代码会是这个样子：WPF CodedUI测试：以编程方式启动应用程序

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)); 
    }

现在，如果我手动启动在我CodedUI测试类在我的ClassInitialize decorded的方法下的应用程序如下：

 [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); 
     }

为什么我如下所示得到下面的空例外？

enter image description here

这也是堆栈跟踪：

System.NullReferenceException was unhandled by user code 
    Message=Object reference not set to an instance of an object. 
    Source=Microsoft.VisualStudio.TestTools.UITest.Framework

    InnerException:

TIA。

您需要初始化播放引擎以在测试方法之外使用CodedUI。该框架会自动初始化testinitalize/cleanup方法中的播放/清理，因此您不会在那里看到它。

ClassInitialize/AssemblyInitialize发生在任何测试开始之前，因此您必须调用Playback.Initialize（）。
