Connecting appium server to selenium grid for android

Nodes are successfully registered with Hub BUT script is always execute on one device only.

Following are the JSON

@Hassan_Radi @Appium_Master @rgonalo Can any one please suggest?

You are trying to select the node with deviceName, but the hub does not use this capability.
The hub only reads browserName, version, platform and applicationName. The other capabilities (deviceName, platformVersion, platformName, ...) are Appium capabilities, not used by the hub.

In your case, you could use "applicationName" capability instead of "deviceName":

Add the capability to each node JSON:

"applicationName": "226CF65ED0ABE221"
"applicationName": "9EDCBB229B2DD02D"

And add the capability to each test:

capabilities.setCapability("applicationName", device_id1);
capabilities.setCapability("applicationName", device_id2);

Thanks @rgonalo !

I updated the files as you suggested.
Still the script is running on one device only. (for device id 1)
I cross checked the device ids and both are correct.
Can you please suggest?

Json file 1 configuration part:
{
"capabilities":
[
{
"browserName": "android",
"version": "4.4.2",
"maxInstances": 5,
"platform": "ANDROID",
"applicationName": "226CF65ED0ABE221"
}
],

Json file 2 configuration part:
{
"capabilities":
[
{
"browserName": "android",
"version": "4.4.2",
"maxInstances": 5,
"platform": "ANDROID",
"applicationName": "9EDCBB229B2DD02D"
}
],

Added
capabilities.setCapability("applicationName", device_id1);
capabilities.setCapability("applicationName", device_id2);
to the script.

@Appium_Master @rgonalo @Hassan_Radi Can you please help in?

I changed the port of a node that is not running and re run the script and unfortunately the script run on the same node that is not specified for.
The same node run on 4723 and 3000 ports though the json files are different for each.
I had started the nodes from cmd prompt. but later only changed jsons and restated appium gui (did not closed and reopened the appium GUI)

Surprising that hub only executes the script on one node though connected to both.

Appium log from the node where script is executed:
info: --> POST /wd/hub/session {"desiredCapabilities":{"app":"D:\APKs\Automated_Projects\abc_staging.apk","appPackage":"com.avaamo.android.staging","appActivity":"com.avaamo.android.ui.LandingActivity","newCommandTimeout":"2000000","platformVersion":"4.4","automationName":"Appium","browserName":"Android","platformName":"Android","deviceName":"30345C56DC2000EC","applicationName":"2636B827A05E6BB3","platform":"ANDROID"}}

info: Client User-Agent string: Apache-HttpClient/4.3.4 (java 1.5)
info: [debug] The following desired capabilities were provided, but not recognized by appium. They will be passed on to any other services running on this server. : applicationName, platform
info: [debug] Using local app from desired caps: D:\APKs\Automated_Projects\abc_staging.apk

I am sure something small is mismatched but I crosschecked the node files and the capabilities provided in script too.

The Appium server seems to have removed the file or maybe it is experiencing some technical issue. Please copy/paste the next few lines in a text file:

@Arvind_Patel @Hassan_Radi
I have configured my android devices to selenium grid with ports 4728 and 4730 below

My selenium grid hub is running on port 4444 And my appiium is on 4723 port

grid_configuration.json
{
"capabilities":
[
{
"browserName": "ANDROID",
"version":"5.0.1",
"maxInstances": 1,
"platform":"ANDROID"
}
],
"configuration":
{
"cleanUpCycle":2000,

"maxSession": 1,
"register": true,
"registerCycle": 5000,
"hubPort": 4444,
"hubHost": "127.0.0.1"
}
}

This is my JSON . I have added this grid_config.json file path to appium setting to Selenium Grid Configuration file.

Now my two android devices are running on different port, right?

This is my java code

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.android.AndroidDriver;

import java.net.MalformedURLException;
import java.net.URL;
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

//import java.net.ServerSocket;

public class sample_test extends initializtion{

AppiumDriver d1,d2;
@Test
public void two_driver(){

	DesiredCapabilities capabilities1= new DesiredCapabilities();
	capabilities1.setCapability("deviceName","Nexus");
	capabilities1.setCapability("platformVersion", "5.1");
	capabilities2.setCapability("appPackage",package name);          
	capabilities2.setCapability("appActivity", main activity);
	capabilities1.setCapability("udid", "0aee8e8b02e4223e");
	
	// capabilities.setCapability("appActivity", "com.whatsapp.Main");
	try {
		d1 = new AndroidDriver(new URL("http://127.0.0.1:4728/wd/hub"), capabilities1);
	} catch (MalformedURLException e) {
		// TODO Auto-generated catch block
		System.out.println("Not able to start application");
		e.printStackTrace();
	}
	d1.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
	
	
	
	DesiredCapabilities capabilities2= new DesiredCapabilities();
	capabilities2.setCapability("deviceName","Moto G 2");
	capabilities2.setCapability("platformVersion", "5.0.1");
	//capabilities.setCapability("app",app.getAbsolutepath());
	capabilities2.setCapability("appPackage",package name);          
	capabilities2.setCapability("appActivity", main activity);
	capabilities2.setCapability("udid", "ZX1D63ZXZ6");
	

	try {
		d2= new AndroidDriver(new URL("http://127.0.0.1:4730/wd/hub"), capabilities1);
	} catch (MalformedURLException e) {
		// TODO Auto-generated catch block
		System.out.println("Not able to start application");
		e.printStackTrace();
	}
	d2.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
	
}

}

But my application is running on only one device , why?
What went wrong here?

ok. got it .. seems like that i messed up with driver capabilities here.
Thanks this tutorial help me a lot

Hi @cool18ap

Can you please share what fixed the problem and files in details that you implemented?

I am facing the same problem.

Thanks!

Hello , @Nitin_Thite i have created new driver for another device for another port
The issue in this line

d2= new AndroidDriver(new URL("http://127.0.0.1:4730/wd/hub"), capabilities1);

I assigned capabilities of first driver to second.That was very silly mistake otherwise it was working fine

Has anyone tried using cucumber-jvm/junit/spring to run parallel tests? I have an existing framework that i would like to enhance with parallel test capability.

Hello,

  I successfully configured my selenium grid with appium. I successfully created to driver for two different android devices . Lets say d1 and d2 . now i want to maintain sink in between them means my driver does some operation using d1 and then after completing that another operation on driver d2. When i am doing operation on d2 another driver d1 should be ideal
  But when i am doing operation on 2nd driver then on first device the app is in background after switching to first device

it gives me error that session is not valid.please help me out here, what should i do? should i implement multi-threading ? or is there any way to put first driver on ideal state while second is doing that operation ?

Has anyone managed to distribute the tests across available devices? This is a native grid functionality, but it doesnt seem to work well with Appium (as you can only run one device per session). A solution, preferably in java, would be helpful - or pointers, I am looking into it myself but seem to be stuck.

Hi @vasanthKS,
Checkout my video, may be it will resolve your issue

@Appium_Master @Arvind_Patel am trying to run a appium script in Two devices [ Node 1(nexus ) , Node 2(Sony) ] in MAC using Selenium Grid concept

I have done the following
1) Created a Hub by using
java -jar selenium-server-standalone-2.45.0.jar -role hub
2) Triggered the nodes as below
NEXUS Device:
node /Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js -a 192.168.1.120 -p 3482 --nodeconfig "/Users/mobilecoe/Desktop/Karthik/Selenium Grid/Nexusin3482.json" --udid 05cd6a0af0ddb24e

Sony Xperia :

node /Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js -a 192.168.1.120 -p 4723 --nodeconfig "/Users/mobilecoe/Desktop/Karthik/Selenium Grid/Sonyin3483.json" --udid BX903K4MC3

Please find below my script and TestNG file

package com.cognizant.grid;

@Parameters({"browserName","platform","deviceName","version"})	
@BeforeMethod
public void beforeMethod(String browserName, String platform, String deviceName, String version ) throws MalformedURLException{
	
	
	
	   DesiredCapabilities capabilities = DesiredCapabilities.android();
	   capabilities.setCapability("browserName", browserName);
	   capabilities.setCapability("platform", platform);
	   capabilities.setCapability("deviceName", deviceName);
	   capabilities.setCapability("version", version);
	   
	   
	   //capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME,"Appium");
	   
	   driver   = new AndroidDriver(new URL("http://localhost:4444/wd/hub"), capabilities);
	
	
}
@Test
public void myTest() throws InterruptedException{
	
	System.out.println("inside");
    driver.get("http://gmail.com/");
    Thread.sleep(2000);
    driver.findElement(By.id("Email")).sendKeys("avkkkkkkkk");
    Thread.sleep(5000); 
	
}

@AfterMethod()
public void afterMethod(){
	
	driver.quit();
}

	
}

And my TestNG xml file is

<?xml version="1.0" encoding="UTF-8"?>

Can you please help me on this ?

I am getting a

org.openqa.selenium.WebDriverException: Error forwarding the new session cannot find : Capabilities [{platform=ANDROID, platformName=Android, browserName=Chrome, applicationName=BX903K4MC3, version=4.3}]

I have connected 2 Android devices one with version 4.3 and another in version 5.0
with device name as BX903K4MC3 & 05cd6a0af0ddb24e

Am I missing some configuration ??? can @Appium_Master , @Arvind_Patel , @Hassan_Radi or any other can help me on this ?
