我想使用c＃和appium测试我的混合应用程序。我知道混合应用程序需要切换到“ WEBVIEW”，但是它不起作用，并且出现错误-
Error: Failed to start Chromedriver session: An unknown server-side error occurred while processing the command. (Original error: unknown error: unable to discover open pages。
当我用Google搜索问题并加以解决时，它仍然无法正常工作。我希望有人分享他们的经验。谢谢。
Appium version: v1.8.0
Android Version: 7.0
Device API: 24
Device:Geny Motion emulator
Chrome driver: 2.37
Chrome version : 67.0
这是我的能力
app: F:\EMSD\App\CCePJM-unsigned.apk
platformVersion: 7.0
deviceName: Android Emulator
platformName: Android
noReset: true
appPackage: hk.gov.emsd.ccepjmstage
appActivity: hk.gov.emsd.ccepjmstage.MainActivity
autoWebview: true
用于设置的部分代码
public void SetUp()
{
capabilities = CapsHelper.GetAndroidCaps();
//get error mentioned above after 120 seconds
driver = new AndroidDriver<IWebElement>(new Uri(MobileCapabilityConfigs.LOCAL_URI), capabilities, TimeSpan.FromSeconds(120));
IList<String> contextNames = driver.Contexts;
driver.Context = contextNames.FirstOrDefault(c => c.Contains("WEBVIEW_"));
}
这是我的日志，供您参考
