android - 安卓并行测试

Question

我用 appium 成功配置了我的 selenium 网格。我成功地为两个不同的 android 设备创建了驱动程序。假设 d1 和 d2。现在我想在它们之间保持接收器意味着我的驱动程序使用 d1 执行一些操作，然后在驱动程序 d2 上完成另一个操作。当我在 d2 上进行操作时，另一个驱动程序 d1 应该是理想的 但是当我在第二个驱动程序上进行操作时，然后在第一台设备上，应用程序在切换到第一台设备后处于后台 它给我一个 session 无效的错误。请在这里帮助我，我该怎么办？我应该实现多线程吗？或者有什么方法可以让第一个驱动程序处于理想状态，而第二个驱动程序正在执行该操作？

public class selenium_grid_example
{

    AppiumDriver d1,d2;
    String id = null;
    DesiredCapabilities capabilities2= new DesiredCapabilities();

    @Test(priority=1)
    public void two_driver() throws InterruptedException{
        DesiredCapabilities capabilities1= new DesiredCapabilities();
        capabilities1.setCapability("deviceName","xxxx");
        capabilities1.setCapability("platformVersion", "5.1");

        } catch (MalformedURLException e) {
            System.out.println("Not able to start application");
            e.printStackTrace();
    }
    d1.manage().timeouts().implicitlyWait(10000, TimeUnit.SECONDS);




capabilities2.setCapability("deviceName","xxxx");
    capabilities2.setCapability("platformVersion", "xxx");
    //capabilities.setCapability("app",app.getAbsolutepath());
    capabilities2.setCapability("appPackage", "xxxx");          
    capabilities2.setCapability("appActivity", "xxxx");
    capabilities2.setCapability("udid", "xxxx");
    capabilities2.setCapability("commandTimeout", 1000);
    d2.manage().timeouts().implicitlyWait(10000, TimeUnit.SECONDS);

}


@Test(priority=2)
public void login_to_application() throws MalformedURLException, InterruptedException{
    here i am doing some operation on driver d1         
    d1.manage().wait(20000);

}

@Test(priority=3)
   public void join_meeting(){
        try {
            d2= new AndroidDriver(new URL("http://127.0.0.1:4730/wd/hub"),     capabilities2);
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
            here i am doing another operation on driver d2
            when i am doing some operation here previously opened app get in background on device one 

        }   
    }
    @AfterClass
    public void quit_driver(){
        try {
            Thread.sleep(40000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("Quiting driver");
        d1.quit();
    d2.quit();
    System.out.println("Driver quited successfully");
    }

}}

这里我得到了这个错误

Answer 1

我认为这是由于两个 session 都试图使用相同的 chrome-driver 端口引起的问题。

启动 Selenium Grid 节点时使用:

appium --nodeconfig/Path/to/Config.json -p XXXX -bp YYYY --chromedriver-port ZZZZ;

确保为每个节点指定三个单独的端口。

希望对您有所帮助，
