Issue in Parallel execution of the script

Support
1

Hi,

Can anyone please help me with this

I am trying to run the test in two emulators emulator-5554 and emulator-5556. Both the appium sessions are registered to the selenium Grid, the JSON files are given below so as the testng xml file.

Issue : Application is getting launched in both the emulators. After that in one emulator application is getting closed automatically and in second emulator the script runs few steps and then shut down without any error. There is no error log in the first emulator as well.

When i launch the appium servers, there is continous log generated with below message :
info: Appium REST http interface listener started on 127.0.0.1:4750

info: [debug] Non-default server args: {“address”:“127.0.0.1”,“port”:4750,“logNoColors”:true,“platformName”:“Android”,“platformVersion”:“23”,“automationName”:“Appium”,“nodeconfig”:“C:\Users\lalithsh\Desktop\json\nodeConfig2.json”}

You can refer to Selenium grid parallel execution fails to run on multiple android devices

Thanks for reply but i am still not able to get pass the issue. Application is getting launched in both the emulators but the steps will be executed in only one of the emulator. Please let me know if you have any solution.

I too noticed this issue, and only workaround that worked for me was launching nodes on different machines and not one.

What do you mean by different machines? are you talking about two different nodes? cause i am already doing that.

Yes different machines, and it works for me perfectly.
