Parallel Execution on different Mobile Platforms

In order to facilitate parallel execution across various mobile devices of same or different platforms we will be using appium with Selenium Grid. Selenium Grid is basically a proxy server that speaks the WebDriver protocol, and manages connections to a pool of WebDriver servers. It wasn't designed specifically to work with Appium, but because Appium also speaks the WebDriver protocol (and because we taught Appium how to register with Selenium Grid)

Details Steps:

Step 1:Set up Selenium Server in Hub Mode

Need to download Selenium-Standalone-Server and start it as hub mode in certain host or port.
```
  java -jar selenium-server-standalone-2.53.0.jar -role hub -host 192.168.3.172 -port 4444
```
Step 2:Start Appium Servers in Node Mode

We can register any number of appium servers in node mode.
- Appium Node 1: Android Node
```
  appium -a 192.168.3.172 -p 4723 --nodeconfig android_nodeconfig.json --chromedriver-executable "chromedriver.exe"
```
Details of android_nodeconfig.json

{
    "capabilities": [
        {
            "deviceName": "ZY224P7HZB",
            "browserName": "chrome",
            "version":"9",
            "maxInstances": 2,
            "platformName": "Android"
        }
    ],

"configuration": {
        "cleanUpCycle":3000,
        "timeout":30000,
        "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
        "maxSession": 2,
        "register": true,
        "registerCycle": 5000,
        "hubPort": 4444,
        "hubHost": "192.168.3.172"
    }
}

Appium Node 2: iOS Node

          appium -a 192.168.5.122  -p 4733 --nodeconfig iOS_nodeconfig.json

Details of iOS_nodeconfig.json:

  {
      "capabilities": [
          {
              "deviceName": "iPad mini 3",
              "browserName": "Safari",
              "version":"12.1",
              "maxInstances": 2,
              "platformName": "i0S",
              "automationName": "XCUITest",
              "xcodeOrgId" : "",
              "xcodeSigningId" : "iPhone Developer",
          }
      ],

  "configuration": {
          "cleanUpCycle":3000,
          "timeout":30000,
          "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
          "maxSession": 2,
          "register": true,
          "registerCycle": 5000,
          "hubPort": 4444,
          "hubHost": "192.168.3.172"
      }
  }

Step 3:The testNgConfig File

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
    <suite name="Suite 1" parallel="tests" thread-count="2">
        <!-- For sequential run use only platform parameter for both (iOS & Android) test cases-->
       <parameter name="hubUrl" value="http://192.168.3.117:4444/wd/hub"></parameter>
        <test name="Android_VerifiyNotifications1">
            <parameter name="deviceName" value="ZY224P7HZB" />
            <parameter name="platformVersion" value="9" />
            <parameter name="platform" value="Android" />
            <parameter name="browserName" value="chrome"/>
            <classes>
                <class name="com.basics.MobileParallelExecutionScript"/>
            </classes>
        </test>

        <test name="iOS_Execution">
            <parameter name="deviceName" value="iPad mini 3" />
            <parameter name="platformVersion" value="12.1" />
            <parameter name="platform" value="iOS" />
            <parameter name="browserName" value="Safari"/>
            <classes>
                <class name="com.basics.MobileParallelExecutionScript"/>
            </classes>
        </test>

    </suite>

Step 3:Java Class


        import io.appium.java_client.ios.IOSDriver;
        import io.appium.java_client.remote.MobileCapabilityType;
        import org.openqa.selenium.By;
        import org.openqa.selenium.remote.DesiredCapabilities;
        import org.openqa.selenium.remote.RemoteWebDriver;
        import org.testng.annotations.Parameters;
        import org.testng.annotations.Test;

        import java.net.MalformedURLException;
        import java.net.URL;

        public class MobileParallelExecutionScript {

            @Test
            @Parameters({"deviceName","platformVersion","platform","browserName","hubUrl"})
            public void test1(String deviceName,String platformVersion,String platformName, String browserName,String hubUrl) throws    MalformedURLException, InterruptedException {

                DesiredCapabilities caps = new DesiredCapabilities();
                caps.setCapability("platformName", platformName);
                caps.setCapability("deviceName", deviceName);
                caps.setCapability("browserName",browserName);
                caps.setCapability("platformVersion",platformVersion);
                caps.setCapability("noReset",true);
                //String url = "http://" + "192.168.3.140" + ":" + "4444" + "/wd/hub";
                String url=hubUrl;
                if(platformName.equalsIgnoreCase("Android")){
                    RemoteWebDriver driver=new RemoteWebDriver(new URL(url),caps);
                    driver.get("https://www.amazon.in/");
                    //driver.findElement(By.xpath("//span[text()='Fresh']")).click();
                    Thread.sleep(7000);
                    driver.quit();
                }else{
                    caps.setCapability(MobileCapabilityType.AUTOMATION_NAME,"XCUITEST");
                    caps.setCapability("xcodeSigningId", "iPhone Developer");
                    caps.setCapability("xcodeOrgId","3WS698JC32");
                    caps.setCapability(MobileCapabilityType.UDID,"bd21c102521b9dc2837ca16c530669006db71f1b");
                    caps.setCapability(MobileCapabilityType.BROWSER_NAME, "Safari");
                    caps.setCapability("startIWDP",true);
                    IOSDriver driver_ios=new IOSDriver(new URL(url),caps);
                    driver_ios.startRecordingScreen();
                    driver_ios.get("https://www.amazon.in/");
                    //driver_ios.findElement(By.xpath("//a[text()='Best Sellers']")).click();
                    Thread.sleep(7000);
                    driver_ios.stopRecordingScreen();
                    driver_ios.quit();
                }


            }

        }

Step 5:Video Browsing

For Android, we can use Vysor Plugin of Chrome.

For iOS, we can perform driver.startRecording, and then open the address ip:9100 of the iOS node machine.
