问题描述
我正在使用Win App Driver自动化WPF应用程序,我们的WPF应用程序是单击一次的应用程序。 启动应用程序时,我发现驱动程序为空。
private string notepadAppid =
@"https://saqa.xyz.biz/abcnew/testets.Shell.Applications";
protected static OpenQA.Selenium.Appium.Windows.WindowsDriver<WindowsElement> driver;
Uri urls = new Uri("http://127.0.0.1:4723");
AppiumOptions opt = new AppiumOptions();
opt.AddAdditionalCapability("app",notepadAppid);
opt.AddAdditionalCapability("deviceName","WindowsPC");
driver = new WindowsDriver<WindowsElement> (new Uri("http://127.0.0.1:4723"),opt,TimeSpan.FromMinutes(1));
我注意到'driver'为null,但出现异常:“无法找到appId为https://saqa.xyz.biz/abcnew/testets.Shell.Applications,processId为-1的打开的应用程序窗口。谢谢。
解决方法
如here所述,您需要检查驱动程序是否为空。
