Appium - Parallel Execution (Grid)

send me test mail to appiummaster@gmail.com

@Appium_Master @Hassan_Radi

Two Different appium driver with different devicename and platform version executes test on same device
Platform i am using is MAC and Android Debug Bridge version 1.0.32 Revision eac51f2bb6a8-android
I am starting two appium servers
server 1 using port 4723 , chrome driver port is 62362
server 2 port is 4743 , chrome driver port is 62366

and i am setting in my desirered capablities
driver1:
url = new URL("http://" 127.0.0.1:4723/wd/hub");
cap.setCapability(MobileCapabilityType.DEVICE_NAME, "LGD8553b0c00b3");
cap.setCapability(MobileCapabilityType.PLATFORM_VERSION,"5.0");

driver2:
url = new URL("http://"0.0.0.0:4743/wd/hub");
cap.setCapability(MobileCapabilityType.DEVICE_NAME, "0123456789ABCDEF");
cap.setCapability(MobileCapabilityType.PLATFORM_VERSION,"4.4.2");

i am trying to launch driver1 and driver2 in one test to verify both devices screen have same values but when i am running test 1-> driver1 is run on LG and appium server 4723 and after that when the turn for driver2 comes the test again runs on LG only with appium server 4743. even though both have different device name and platform version in desiredcapablities.
when i execute adb devices it shows both devices are connected but when i am executing it from appium, whichever device is listed first both tests are executed on it. does the devicesName parameter does not affect the execution ?

here is the log of driver2 appium server

@salmanchauhan
You need to provide the device UDID capability in order to tell the adb to select the correct device to run the test on.

Thanks alot man you saved my day @Hassan_Radi

Hello Everyone,

i have a issue registering node using appium

my json file is

Please help

Thank you

It won't be in 1.5, but appium 1.5 includes a lot of code that makes parallel sessions possible.

So expect it to come as a major feature after 1.5.

@jonahss I see. Until then, what do you think is the best way to run tests in parallel on iOS devices ? This Instruments limitation of 1 device per machine is still a thing, right ? So VM's would be a legit approach still ? Thanks !

Hello guys.
I can help you out in setting up Selenium Grid for Appium tests.
We have a Grid setup where Android and IOS tests run parallel.
Please feel free to contact me.

Thanks and Regards,
Pranoday

Hello Pranodyad, would you mind helping me on this? Having hard time with this. I would need All Nitty-gritty from setting up selenium grid/hub to changes in eclipse for supporting parallel devices

My Email Id- shankeytyagi97@gmail.com.

Looking forward for your response.

Hi @Shankeyisgem.

In order to setup Selenium grid for Appium tests you need to have Selenium Hub running and 2 nodes,1 with Android capabilities and another with IOS capabilities registered with the hub.

Now if you are having your testsuite specified in TestNG.xml then you can specify parameter say e.g. "IOSTest" for a test which you want to give to IOS device to run and you can specify parameter e.g."AndroidTest" for a test which you want to give to Android device to run.

These settings "IOSTest" and "AndroidTest" based on which test distribution is going to happen,should be present in BrowserName capability included in .jason file which you may be using to start and register nodes.

And at script side you will be receiving these TestNG parameters and using it to set BrowserName DesiredCapability while instantiating DesiredCapabilities object which you will eventually use to create Driver object.

Note that to distribute tests among the registered nodes,"BrowserName" is the capability which Selenium Grid takes into consideration.

Hope this will help you out.If you want any other details then please feel free to contact me.

Thanks and Regards,
Pranoday

Thanks for your reply Pranodayd,

Couple of things:

1. I could set up selenium grid by issuing command in cmd but for registering Hubs which port numbers I should provide? Or can we have this Hub/node configuration specified in Eclispe for batter handling?

2. Actually I have very minimally used Appium with eclipse. So only simple script that I have is just to launch mobile app and some tapping arround and this script is just definded in a class file under eclipse project and when I running it as Tesng, it's going fine for my configured android device and I want to run this script in multiple devices.

Now that said, I have no Idea as how to configure Testing.XML/Json file in eclipse as you mentioned.
Can you send across some working code for same so that it is more clea for me?

Hi @Shankeyisgem

No need to use Eclipse to configure and trigger Selenium Grid execution.You can configure TestNG.xml and .json files using any editor like Notepad etc.

following is and example .json file:
{
"capabilities":
[
{
"browserName": "IpadMiniDevice",
"version":"8.5",
"maxInstances": 1,
"platform":"MAC",
"deviceName":"IpadMiniDevice"
},

        {
	"browserName": "AllIpadDevices",
	"version":"8.5",
	"maxInstances": 1,
	"platform":"MAC",
	"deviceName":"AllTabletDevices"	    
        }
],

"configuration":
{
	"cleanUpCycle":2000,
	"timeout":0,
	"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
	"url":"http://<IpAddress on Which AppiumServer is running:Port on Which AppiumServer is running>/wd/hub",
	"maxSession": 1,
	"port": <Port on Which AppiumServer is running>,
	"host": <IpAddress on Which AppiumServer is running>,
	"register": true,
	"registerCycle": 5000,
	"hubPort": <Port on Which Selenium Grid hub is running>,
	"hubHost": <IpAddress on Which Selenium Grid hub is running>
}

}

You can start Selenium Grid hub and nodes using following dos commands:

To start Hub use following command:
java -jar -timeout 0 -remoteControlPollingIntervalInSeconds 300 -role hub

To start and register node use following command:
java -jar -role node -nodeConfig

Thanks and Regards,
Pranoday

Hi thank you! Could you please share the TestNG file you are using ? I was wondering why you actually start a "normal" node not a Appium node ? Like:

appium --nodeconfig /nodeconfig.json

Do you start Appium separately with specific arguments then ?

You can just start the two nodes without registering it into the hub.

@bhaskar

my selenium grid is running but when i try to run node server by "node appium --nodeconfig /Users/RajShekhar_DiroLabs/Desktop/node1.json -p 4730 -bp 4730"

its shows me logs like

@saikrishna321 Is it possible parallel execution in iOS devices?

@sanoj27 yeah you can run parallel tests on iOS real devices ..

hello,

During start node server it shows a error "Syntax error in node configuration file: Unexpected token P"

I am able to run appium tests on two different devices but they run one after the other. I want them to run on both the devices simultaneously(parallel). I am running appium on two different ports.This is how I am doing it.

Can anyone help me how to do it?

With 1.5 new features says, you can start multiple sessions in 1 server. Or did i understand badly?

At the moment I'm using 2 emulators in paralel with selenium grid. It works fine but I have to open a new appium server for all emulators I need. So if I want to run with 20 different device emulators, I need to launch 20 appium server, which is not cool. My configuration is like this;

appium -a 172.20.0.196 -p 4723 --session-override --nodeconfig appiumnodeconfig1.json
appium -a 172.20.0.196 -p 4724 --session-override --nodeconfig appiumnodeconfig2.json

}

The thing is, I want to start only 1 appium server and connect multiple emulators to it. Can I do it and how?
Thanks in advance

Check here www.appiumforbeginners.com89 for Appium Grid concept

Thank you but it doesn't answer my question. Tutorials on the website shows exactly the same configuration with mine. You have to open a server for every node.

But I already got the answer from Jonathan Lipps yesterday. He told me that 1.5 work was the groundwork for that new feature, but the feature itself is not released. I guess we're going to have to wait unfortunately.

Yes you can run by use parallel thread concepts with out use selenium grid

Hi @pushpank

Can you please share the steps to run appium script parallel without using selenium grid infrastructure.

Thanks
Ravi Kumar

Hi @bhaskar,

After doing everything as I found in the discussions, I was able to launch android app in multiple devices in parallel. But after that, only one device was able to finish the rest of the automation, other devices got stuck right after launching app.

P.S.: I was able to launch apps using session overriding, otherwise I was not able to launch apps in parallel even though different servers were running.

Thanks,
Minar
