Connecting appium server to selenium grid for android

Hi sam_viz,

Thanks for the reply.

Thanks for the tip ! It's even better this way

@tovaibhav1

These two lines are the ones causing the issue. You are using invalid double quotes, thus the inability to parse the json file. Please use this site to validate your json file: http://jsonlint.com/25

Change every ” to be "

Thanks @Hassan_Radi but I used command from location "C:\Program Files (x86)\Appium\node_modules\appium\bin>"

node appium -a 192.168.1.2 -p 4723 --nodeconfig D:\TehnologyWork\Softwares\jar\node1.json

I am receiving error

C:\Program Files (x86)\Appium\node_modules\appium\bin>node appium -a 192.168.1.2 -p 4723 --nodeconfig D:\TehnologyWork\Softwares\jar\node1.json

@tovaibhav1
Please provide the full stack trace.

@Hassan_Radi its full stack trace in command prompt

@tovaibhav1
I am not sure what is causing this weird issue, but if I were you, I would try to load the same file using Appium .exe application and see how it would react. This would tell me if it is a problem with the file itself or the parameters I am passing.

@Hassan_Radi
please xplain "load the same file using Appium .exe application" what you mean and how to achievwe

@Hassan_Radi'
Thanks a lot, my silly mistake has wasted your time, path in json was to be "jars" instead of "jar" :smpersevere:

@Hassan_Radi Please guide

My node are:
node1.json

{
"capabilities": [
{

"maxInstances": 3,
"platform": "ANDROID",
"deviceName": "X1033"

Started HUB

java -jar selenium-server-standalone-2.48.2.jar -role hub

Started Nodes

node appium -a 127.0.0.1 -p 4723 --nodeconfig D:\TehnologyWork\Softwares\jars\node1.json

node appium -a 127.0.0.1 -p 4728 --nodeconfig D:\TehnologyWork\Softwares\jars\node2.json

When I execute test for any device, always script runs in one appium server which is started firstly i.e. node1.

public static ThreadLocal> dr = new ThreadLocal>();

@BeforeMethod
@Parameters("deviceName")
public void beforeMethod(String deviceName) throws MalformedURLException{
	try{
		if(deviceName.equals("XT1033")){
			AndroidDriver<MobileElement>  driver = null;
			DesiredCapabilities capabilities=new DesiredCapabilities();
			capabilities.setCapability("platformName", "Android");
			capabilities.setCapability("platformVersion","5.1");
			capabilities.setCapability("deviceName", deviceName);
			capabilities.setCapability("app",System.getProperty("user.dir") + "/resources/app-Channel31-debug.apk");
			URL serverAddress = new URL("http://127.0.0.1:4444/wd/hub");
			driver = new AndroidDriver<MobileElement>(serverAddress, capabilities);
			setDriver(driver);

		}
		if(deviceName.equals("emulator_1")){
			AndroidDriver<MobileElement>  driver = null;
			DesiredCapabilities capabilities=new DesiredCapabilities();
			capabilities.setCapability("platformName", "Android");
			capabilities.setCapability("platformVersion","5.1.1");
			capabilities.setCapability("deviceName", deviceName);
			capabilities.setCapability("app",System.getProperty("user.dir") + "/resources/american swan- prod.apk");
			URL serverAddress = new URL("http://127.0.0.1:4444/wd/hub");
			driver = new AndroidDriver<MobileElement>(serverAddress, capabilities);
			setDriver(driver);
		}
	}

Hi @tovaibhav1,
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 this case, you could add version capability to each test:

capabilities.setCapability("version","5.1");
capabilities.setCapability("version","5.1.1");

I can see there are some success using appium grid over Selenium but is there one person that managed to do this using windows (without emulator!) simply** two Android devices**?

Hello all,

I'm trying to have some mobile automated tests running with appium and selenium grid. Once i done all configuration stuff and added grid nodes, how do i run my tests parallely in both devices?

Here's my setUp():

desired_caps = {}
	desired_caps['platformName'] = 'Android'
	desired_caps['platformVersion'] = '5.1'
	desired_caps['deviceName'] = ''
	desired_caps['app'] = os.path.abspath(os.path.join(os.path.dirname(__file__), 'C:/Users/andre.mendes/Desktop/workspace/powerpro/apps/powerpro.apk'))
	desired_caps['appPackage'] = 'com.psafe.powerpro'
	desired_caps['appActivity'] = '.MainActivity'
	desired_caps['noReset'] = False
	self.driver = webdriver.Remote('http://127.0.0.1:4444/wd/hub', desired_caps)
	self.driver.implicitly_wait(15)

What it supposed to be in deviceName in this case?

If i leave it blank, here's what i got:

C:\Users\andre.mendes\Desktop\workspace\powerpro>java -jar selenium-server-standalone-2.44.0.jar -role hub

I only can run the first node registered in grid. In this case http://127.0.0.1:47231.

I even tried to create a script with two setup(), each one to each device, but even this way, tests only ran in this same device (http://127.0.0.1:4723)

I have started working on running parallel android devices by using grid.My Problem is the app installed and opened both connected devices properly.but it has not typed any values which i have given. After that it shows error message in setup method.
Can anyone help me for this issue????
