Appium - Parallel Execution (Grid)

[Daniel_Lozynski]

@jonahss Will parallel tests be part of 1.5 ? Just asking because your post is from June 2015...Thanks

[jonahss]

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.

[Daniel_Lozynski]

@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

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?

[Pranodayd]

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 ?

[Sumona]

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??

[janardhanreddy]

Hi Bhashkar,

Can u please send me the document if any to start Appium Grid with Mac for One Machine with Multiple Devices.
Please do the needful Send me the Document if possible to janardhanreddyqa@gmail.com

Thanks & Regards,

Here is my setup.. hope it will solve parallel execution issue.

[charivb]

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.

[PavithraRavichandran]

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

[yadsandy]

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

[sanoj27]

@saikrishna321 Is it possible parallel execution in iOS devices?

[saikrishna321]

@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?
