Appium - Parallel Execution (Grid)

Pranodayd · Mar '16

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,

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 ?

Hi Bhaskar,

Could you please help me know how you did with single driver instance?? Currently i am able to do that by creating multiple capabilities object and passing them on multiple driver instances. This is not the correct approach i know. Please help me how did you define in your class file and xml. Please.

if possible could you share your code snippet??

Hi,

can you please suggest us how can we make sure two appium server start for parallel device execution with out using selenium grid
looking for u r reply

Thanks in advance

chari.

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

Can I execute parallel test without grid? If yes then How? please suggest

@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?

saikrishna321 · Jun '16

@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.
appium -p 4725 -bp 4735 -U "706b9496" --chromedriver-port 9518
appium -p 4735 -bp 4745 -U "ZX1B34JFZK" --chromedriver-port 9528

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

appiumnodeconfig1.json:
{
"capabilities": [
{
"browserName": "android",
"version": "5.1",
"platform": "ANDROID",
"maxInstances": 1,
"deviceName": "192.168.56.101:5555"
}
],
"configuration": {
"nodeTimeout" : 120,
"port": 4723,
"hubPort": 4444,
"url": "http://172.20.0.196:4723/wd/hub",
"hub": "172.20.0.196:4444/grid/register",
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"hubHost": "172.20.0.196",
"nodePolling": 2000,
"registerCycle": 10000,
"register": true,
"cleanUpCycle": 2000,
"timeout": 30000,
"maxSession": 1
}
}

appiumnodeconfig2.json:
{
"capabilities": [
{
"browserName": "android",
"version": "5.1",
"platform": "ANDROID",
"maxInstances": 1,
"deviceName": "192.168.56.102:5555"
}
],
"configuration": {
"nodeTimeout" : 120,
"port": 4724,
"hubPort": 4444,
"url": "http://172.20.0.196:4724/wd/hub",
"hub": "172.20.0.196:4444/grid/register",
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"hubHost": "172.20.0.196",
"nodePolling": 2000,
"registerCycle": 10000,
"register": true,
"cleanUpCycle": 2000,
"timeout": 30000,
"maxSession": 1
}
}

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

Taylan · Jun '16

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.

pushpank · Jul '16

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

ravikr42 · Jul '16

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
