【问题描述】：
我尝试在混合应用程序中运行测试用例。
我可以使用 driver.context("WEBVIEW") 切换到 WebView。
但是在我切换到 webview 之后，driver.findElement() 方法在 webview 下不执行，它在 Appium 服务器中返回错误，如下所示。你能帮我解决这个问题吗？
以下是我的测试脚本：
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
capabilities.setCapability("deviceName","066e28s70b115a3b");
capabilities.setCapability("platformVersion", "4.4.2");
capabilities.setCapability("platformName","Android");
capabilities.setCapability("app", "/Users/lin/codes/tester.apk");
capabilities.setCapability("app-package", "com.test.tester");
capabilities.setCapability("app-activity", "com.test.tester.myActivity");
AppiumDriver driver = new AppiumDriver(new URL("http://my.local.address:4723/wd/hub"), capabilities);
Set<String> contextNames = driver.getContextHandles();
System.out.println(contextNames.size());
for (String contextName : contextNames) {
System.out.println(contextName);
if (contextName.contains("WEBVIEW")){
driver.context(contextName);
}
}
Thread.sleep(5000);
driver.findElement(By.xpath("//div[@class='item item-entrance']/h2[@class='grey-title mb20']")).click();
以下代码不起作用：
driver.findElement(By.xpath("//div[@class='item item-entrance']/h2[@class='grey-title mb20']")).click();
这是来自 Appium 服务器日志的错误消息：

顺便说一句，我从源 (>node appium.js --no-reset) 启动了 Appium 1.0.0 服务器。

请重启设备尝试，否则使用GUI版appium。
-
我可以通过在测试执行期间一直监控 chromedriver 来修复，当从 natiove_app 切换回 webview 时 chromedriver 变得无响应。我在github.com/mi2pankaj/chromeDriverHandler 开发了一小段代码，它解决了我所有的问题，只需将此jar chromedriverHandler.jar 添加到您的项目中并使用ChromedriverHandler.chromeDriverHandlerThread().start();在你的 beforeclass / beforetest 和 ChromedriverHandler.chromeDriverHandlerThread().stop();在你的课后/课后
