Question

我正在为WPF应用程序编写一个编码的ui。该项目包含大约30个测试，并且在测试初始化时我有提交Login的方法。问题是在某些情况下我得到错误：

Microsoft.VisualStudio.TestTools.UITest.Extension.PlaybackFailureException was unhandled by user code
  Message=Cannot perform 'SetProperty of Text with value "admin"' on the control. Additional Details: 
TechnologyName:  'UIA'
ControlType:  'Edit'
AutomationId:  'UserName'

大多数情况下，此错误不会发生。

我很难找到错误一致性。

我可以说，如果我将重新启动代理服务并将运行30测试 - 我将不会有此错误。但如果我将运行10测试 - 没有服务重启 - 再次运行10测试我将有可能错误重现。

此问题与IE有关。您可能希望通过卸载IE的更新版本来暂时考虑解决方法为此，
（1）打开关于IE
（2）点击“自动卸载IE新版本更新”复选框
（3）点击“确定”。
此新版本（KBxxxxxxxx）将作为已安装更新的Windows安全更新提供。您可能需要暂时考虑解决方法，但请注意，您将卸载重要的安全更新。

编码的ui - 无法对文本框执行“SetProperty”
