在resetApp之后切换到webview上下文会出现异常“chrome not reachable”

问题描述 投票：0回答：1

环境

Appium : 1.6.4
OS : Ubuntu 16.04 64bit
Node.js : 7.9.0
Android : 5.1
Device :1501-M02
API :java
Appium CLI

细节

我使用spock作为测试框架，带有代码：

class Test{
      AndroidDriver<RemoteWebElement> driver;
      DesiredCapabilities cap=DesiredCapabilities.android();
       ........
      def setup(){
            //setup driver
              .....
             cap.setCapability(NO_RESET, "true");
         cap.setCapability(FULL_RESET, "false");
          .....
             cap.setCapability(RECREATE_CHROME_DRIVER_SESSIONS, "true");
             .......
             driver.context("WEBVIEW_com.domain.pkg");
      }

      def "test1"(){}

      def "test2"(){}

      def cleanup(){
             driver.resetApp();
      }
}

在eclipse中，如果右键单击test1或test2->运行as-> junit test，两者都按预期运行，但如果右键单击Test（类） - >运行as-> junit test，第一个测试工作，第二个测试会抛出异常：

  org.openqa.selenium.WebDriverException: chrome not reachable
  (Session info: webview=39.0.0.0)
  (Driver info: chromedriver=2.28.455506

如果用这个替换cleanup（）：

def cleanup（）{driver.quit（）; }

一切都按预期工作，但每次测试都会重新初始化很多浪费大量时间的员工，所以

driver.resetApp()

没有按预期工作，这是一个错误还是我做错了什么？

像这样的appium日志：

使用新的UIautomator，您无需将驱动程序切换到webview。它内置了识别webView内部元素的功能。

请更新您的Android SDK一次。

WebView中的元素将在UIAutomator for Android Version 6.0+版本中可见。但是，一旦为Android 6.0+设备自动执行脚本，就可以对6.0以下的Android版本使用相同的脚本。

此外，您还可以使用UIAutomator在Android 6.0+设备上查看webView中的元素。
