Connecting appium server to selenium grid for android

@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;

import java.net.MalformedURLException;

@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 ?

It should be “deviceName” not “applicationName”.

Hi , Based on the some of the earlier post in this page i have changed to applicationName from deviceName , after this now one device [ first device in adb devices list ] alone is getting executed in the grid

As the documentation mentions, you have to use different

-p the main Appium port
-U the device id
-bp the Appium bootstrap port
–chromedriver-port the chromedriver port (if using webviews or chrome)
–selendroid-port

Hi all,

I’m getting below error while connecting to Grid using Appium , the second device getting error and one device is executing fine.

Hi All @Appium_Master @Hassan_Radi @Arvind_Patel @rgonalo ,
I have reduced the capabilties listed and now i am able to run my scripts sequentially one after the another . But when i tried the same with parallel flow in One device the script runs fine and in another device the script throws " An unknown server-side error occurred while processing the command.",“origValue”:"Did not successfully proxy server command and it shows a Blank while screen in the device

    executing cmd: /Users/mobilecoe/Documents/adt-bundle-mac-x86_64-20140321/sdk/platform-tools/adb -s BX903K4MC3 shell "am force-stop com.android.chrome"

@vijayakarthikeyan
Most of us in this forum are facing the same issue, If you see my video which I uploaded on youtube I clearly mentioned that. Parallel test only work if one device is slower than second or you can put sleep in b/w calling the devices in code. It will run one after other but you will get parallel test reports.

Hi @Appium_Master @Arvind_Patel @rgonalo @Hassan_Radi . Now I am able to run my test case parallely and sequentially for Android devices

I will post all the steps below to run the scripts parallely

  1. START THE HUB

    java -jar selenium-server-standalone-2.45.0.jar -role hub -hub http://xxxxxxxxx:4444/grid/register

  2. START THE APPIUM NODE
    FIRST DEVICE :
    node /Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js -a 192.168.1.109 -p 4723 --nodeconfig “/Users/mobilecoe/Desktop/Karthik/Selenium Grid/Nexusin4723localwithmachineIP.json” --udid xxxxxxxxxxxxx --bootstrap-port 2252 --chromedriver-port 4735

SECOND DEVICE:

node /Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js -a 192.168.1.109 -p 4725 --nodeconfig “/Users/mobilecoe/Desktop/Karthik/Selenium Grid/Sonyin4725localusingMachineIP.json” --udid xxxxxxxxx --bootstrap-port 2251 --chromedriver-port 4733

NOTE: I am using Mac

  1. Create the TestNG project with the xml setting pointing the desired capabilities

    <?xml version="1.0" encoding="UTF-8"?>
      <test name="SeleniumGrid_Sony" >
      
      <parameter name="browserName" value="Chrome"/>
      <parameter name="platform" value="Android"/>
      <parameter name="deviceName" value="XXXXXXXXX"/>
      <parameter name="version" value="4.3"/>
      <parameter name="sleep" value="1000"/>
     <classes>
       <class name="com.cognizant.grid.SeleniumGrid_mobile"/>
       
     </classes>
    
      <parameter name="browserName" value="Chrome"/>
    	<parameter name="platform" value="Android"/>
      <parameter name="deviceName" value="XXXXXXXXXXXXX"/>
      <parameter name="version" value="5.0"/>
      <parameter name="sleep" value="15000"/>
       
     <classes>
       <class name="com.xxxxxx.grid.SeleniumGrid_mobile"/>
       
     </classes>
    

And its working fine for me

How to create an Appium Node for Iphone device ?

What are Terminal command line codes to be mentioned for it ? like bootstrap , chromedriver for Android .

@Appium_Master @Hassan_Radi @Arvind_Patel @rgonalo @karthik_holla @Srikanth_Katakam any idea on this ?

I have created a separate thread for this discussion but decided to include this question in this thread as it seems to be active.

I need help on running test cases from Selenium Grid server machine running as a hub with the devices connected to the node and here’s what I have:

I have a iMac running Mavericks (10.9.5) running Selenium Grid server as a hub. I also have a MacBook Air (running on Mavericks) running Selenium Grid as a node. Appium is running from terminal on port 5000 with --uuid parameter pointing to my iOS device connected to the node.

What works:

If the test cases are on the node, I’m able to run 2 devices in parallel from the node and the node is pointing to the Selenium Gid hub on the iMac.

What I wanted to achieve: (for troubleshooting, I’m only connected to one iOS device on the node).

I would like to have the test cases on the hub machine and this will give me a benefit of having the test scripts in one single location rather than duplicating on each of the nodes. I changed the DesiredCapabilities to point to the node and when I try to instantiate a new IOSDriver, I’m getting a “Session not created error: Bad app: Unable to locate the app”. The app is located on the server hub and the path is all correct as I verified from the command line on the server with the stat command and it returns back the .app file. The following is the code that is run from the hub machine:

app = /Volumes/Server/Apps/iOS/SampleApp.app (the sample app is lying on the server from where the following code is running:
File appPath = new File(app);
capabilities.setCapability(“app”, appPath.getAbsolutePath());
IOSDriver iOSDriver= new IOSDriver (new URL(http://nodeipaddress:5000), capabilities);
The code is throwing exception on the last line when it is trying to instantiate a new IOSDriver.

But, the same code works when run from the node as shown below. Also, the SampleApp.app is lying on the node.
app = /Volumes/Node/Apps/iOS/SampleApp.app
File appPath = new File(app);
capabilities.setCapability(“app”, appPath.getAbsolutePath());
IOSDriver iOSDriver= new IOSDriver (new URL(http://hubipaddress:4444), capabilities);

I tried the following:
1.changed from getAbsolutePath to getCanonicalPath() and it fails with the same error
2.Changed the path to System.getProperty(“user.dir”) + "…/…/Node/Apps/iOS and this doesn’t work too.

Ideally, I wanted to keep the test cases in one location and remote execute on the devices connected to the node. Please help.

So, to summarize, when the test cases are run from the hub machine (Machine 1) with the .app lying in a folder on the hub machine, I would like the .app to be installed on the device connected to the node (Machine 2) while the test cases are running from Machine 1.

Thanks.

Anybody?

No matter how I change my code, I’m getting Bad app error (App path needs to be absolute…blah…blah…blah), when trying to run the code from the hub while the devices are connected to a node (different machine) with appium listening on port 5000 and selenium grid running as a node.

Please help.

Hi @appium_ia,

App capability can be a local path or a remote url (http://appium.io/slate/en/master/?ruby#appium-server-capabilities).
If you have a local path with Selenium Grid, Appium searches the app in the node machine, not in the hub machine.
You should use a remote url or a shared folder path that can be accessed from any node machine.

Hi tried all the workarounds mentioned in the above blog but at a time I am able to run test on only one device. For second its throwing error: "org.openqa.selenium.SessionNotCreatedException: A new session could not be created.

}

Anyone any solution for my issue? Tried a lot different things with no success

WORKING GREAT with Caveats!!

Finally, I was able to achieve what I need. To rephrase, this is my setup:

Selenium Grid Hub: Running on iMac with Yosemite/Maveicks (Also tried with Windows 10 Preview using Bootcamp). Source for the test scripts are on the hub and NOT on each of the nodes. This is very important as I wanted to have the source in one single location for getting latest from SVN.

Selenium Grid Node: Running on MacBook Air:
Connected 2 devices (iPhone 6+ and Samsung Note II). Each of the devices are running on different appium ports. Selenium grid node are instantiated on each of the ports appium is listening (more on this later).

For debugging purposes, I installed IntelliJ on the hub machine (iMac) and when the test cases start running, I was seeing parallel run on both the devices at the same time (on the node machine). So far so good. I did the same with Windows 10 Preview (on the hub) and it works extremely well too. So, Windows hub can talk to Mac nodes. Awesome!

Now, the issue: I wanted to see if it works with Windows node. I disconnected the Android device (Samsung Note II) and plugged in to Windows 7 laptop while the hub is running on Windows 10 Preview (I think Windows OS shouldn’t matter here). When I ran the test case from the hub on Windows 10 Preview, at the line where the AndroidDriver is instantiated, I got a Internet Explorer Driver error asking me to set this: System.setProperty(“webdriver.ie.driver”, “C:\SeleniumDrivers\IEDriverServer.exe”);

I did this on both the server and the node (both running on Windows OS). Then, I got one more new error:
org.openqa.selenium.WebDriverException: Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones. (WARNING: The server did not provide any stacktrace information).

My first question is I’m at loss on why these errors about Internet Explorer are happening when I’m trying to run an Android native app on the phone connected to a node remotely. These kind of issues are not happening when both the hub and the node are on OS X and also when the hub is on Windows 10 Preview and the node is on OS X. These pesky errors only happen when both the hub and node are on Windows OS. I haven’t tried where the hub is on OS X and the node is on Windows 7.

And here’s the snippet that I’m using to instantiate appium servers and grid nodes on the node machine:
C:\Program Files\nodejs>node C:\Users\username\AppData\Roaming\npm\node_mod
ules\appium\bin\appium.js --port 6000 --bootstrap-port 6025 --udid “android device id” --app-pkg “android package name” --app-activity “android activity name”

C:\Automation\Server>java -jar selenium-server-standalone.jar -role node -browse
r browserName=Android,version=4.3,maxinstance=1,platform=WINDOWS,applicationName
=“udid” -Dwebdriver.ie.driver=C:\WebDrivers\IEDriverServer.exe -hub http://hubip:4444/grid/register -port 6000

I have to add the -Dwebdriver.ie.driver to make the nasty InternetExplorer Driver location failure to go away. Still getting the protected zone error.

Puzzled on why all of these when I’m trying to run a native android app on and android phone connected to a Windows OS node.
Btw, is the browsername correct? I’m just automating a native iPhone and a Android app.

Anybody, with any thoughts?

Thanks.

Is there anything for python like TestNG? i have configured everything, my only problem is how to run parallel Tests, any help will be good.

All examples using the .xml file are for Java, i want to know if there is something like that for python.

Thanks

Selenium code:
for node 1:

@Parameters(value={“device_id1”,“device_id2”, “ApplicationPath”})
@BeforeSuite//The annotated method will be run before all tests in this suite have run.
public static void atStart(@Optional(“nnn”) String device_id1, String device_id2, String ApplicationPath) throws InterruptedException, IOException

            capabilities.setCapability("automationName", "Appium");

            capabilities.setCapability("applicationName", device_id1);

            capabilities.setCapability("appActivity", "com.avaamo.android.ui.LandingActivity"); //Replace with app's Activity
            //setting new command timeout for selenium server
            capabilities.setCapability("newCommandTimeout", "2000000");//33.33 mins
            
                try
                {
                    driver = new AndroidDriver(new URL("http://127.0.0.1:4441/wd/hub"), capabilities);
                }
                catch (Exception e)
                {
                    System.out.println("didnt work for !" +device_id1);
                }

}

:: The same code with some values change for node 2.

Can anyone please help understanding whats going wrong, or possible solution?

I have added deviceName in json files and have put the same in capabilities in script.
though I don’t see any progress.
