在appium iOS中切换两个应用程序

Question

我有一个测试用例，在iPhone中我必须1。在app a.2中执行一个任务。切换到Safari浏览器并执行任务3。再次切换回应用程序A并继续其他任务

目前，我可以执行1&2&然后切换回应用程序A，但从safari浏览器切换后，我不能在应用程序A中执行任何任务。我所做的如下。

public void createAppiumDriver() throws MalformedURLException, InterruptedException {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "iPhone 7 Plus");
capabilities.setCapability("platformName", "iOS");
capabilities.setCapability("platformVersion", "11.2"); 
capabilities.setCapability("autoWebView", true);
capabilities.setCapability("app", getProperties().getProperty("appURL"));
capabilities.setCapability("autoAcceptAlerts", true);
capabilities.setCapability("useNewWDA", true);
capabilities.setCapability("startIWDP",true);
iosDriver = new IOSDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);}

为了从我的应用程序切换到Safari，我使用以下代码启动了一个新的会话来切换到Safari

public void openSafari() throws MalformedURLException {
DesiredCapabilities capabilities2 = new DesiredCapabilities();
capabilities2.setCapability("deviceName", "iPhone 7 Plus");
capabilities2.setCapability("platformName", "iOS");
capabilities2.setCapability("platformVersion", "11.2");
capabilities2.setCapability("browserName", "Safari");
capabilities2.setCapability("autoAcceptAlerts", true);
capabilities2.setCapability("useNewWDA", true);
iosDriver2 = new IOSDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities2);
iosDriver2.get("https://www.gmail.com");}

现在的问题是再次从safari浏览器切换回App A来执行一些任务，目前我已经再次创建了一个新的会话，如下所示

public void switchToNutrifix() throws MalformedURLException, InterruptedException {
DesiredCapabilities capabilities3 = new DesiredCapabilities();
capabilities3.setCapability("deviceName", "iPhone 7 Plus");
capabilities3.setCapability("platformName", "iOS");
capabilities3.setCapability("platformVersion", "11.2"); //Replace this with your iOS version
capabilities3.setCapability("autoWebView", true);
capabilities3.setCapability("app", getProperties().getProperty("appURL"));
capabilities3.setCapability("autoAcceptAlerts", true);
capabilities3.setCapability("useNewWDA", true);
capabilities3.setCapability("startIWDP",true);
iosDriver3 = new IOSDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities3);}

现在的问题是应用程序A再次从Safari打开，但它无法识别应用程序中的元素。我甚至正确地将上下文更改为webview，但从Safari浏览器切换后，它仍然不能执行App A中的任何任务。有人能告诉我我在这里做错了什么吗？或者另一种方法来做这个切换。

public class SwitchBtnAppsiOS {

public AppiumDriver<RemoteWebElement>iosDriver;

public DesiredCapabilities createAppiumDriver()
    throws MalformedURLException, InterruptedException {
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("deviceName", "iPhone 7 Plus");
    capabilities.setCapability("platformName", "iOS");
    capabilities.setCapability("platformVersion", "11.2"); 
    capabilities.setCapability("autoWebView", true);
    capabilities.setCapability("app", getProperties().getProperty("appURL"));
    capabilities.setCapability("autoAcceptAlerts", true);
    capabilities.setCapability("useNewWDA", true);
    capabilities.setCapability("startIWDP",true);
    return capabilities;
}


public DesiredCapabilities openSafari() 
    throws MalformedURLException {
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("deviceName", "iPhone 7 Plus");
    capabilities.setCapability("platformName", "iOS");
    capabilities.setCapability("platformVersion", "11.2");
    capabilities.setCapability("browserName", "Safari");
    capabilities.setCapability("autoAcceptAlerts", true);
    capabilities.setCapability("useNewWDA", true);
    return capabilities;
}

public void switchBetweenApps() throws MalformedURLException, InterruptedException
{
    DesiredCapabilities nativeAppCaps = createAppiumDriver();
    iosDriver = new IOSDriver<>(new URL("http://0.0.0.0:4723/wd/hub"), nativeAppCaps);

    /**
     * Perform the actions on native app
     */

    DesiredCapabilities webCaps = createAppiumDriver();
    iosDriver = new IOSDriver<>(new URL("http://0.0.0.0:4723/wd/hub"), webCaps);
    iosDriver.get("https://www.gmail.com");

    /**
     * Perform the actions on safari browser 
     */

    // Again switch to native app
    iosDriver = new IOSDriver<>(new URL("http://0.0.0.0:4723/wd/hub"), nativeAppCaps);
}
}

1. 在使用驱动程序实例的地方，传递驱动程序的最新实例。
2. 如果是这样的话，请使用RemoteWebElement而不是MobileElement。
