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)

Architectural Diagram

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 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.
