Connecting appium server to selenium grid for android

karthik_holla · Jan '15

I am trying to launch chrome browser on Moto x (Android kit kat) and Nexus 5(Lolipop).

Following things are done in the code:
1)Launch grid
2)I am having a dataprovider which feeds the mobile info as objects one after the other to tests I have configured the dataprovider to provide the objects parallely. Using this information i am preparing the desired capabilities which will be used for initalizing appium driver.
3)Launch appium servers as per the configuration mentioned in the dataprovider object and register it with hub
4)Execute the test.

The problem i am facing is that tests are executed in a single device but is failing when trying to execute it on another device. I am suspecting time issue or some config issue.

Can you please post the code for the above video, it would be helpful.

Thanks and regards,
Karthik

@karthik_holla,
@Srikanth_Katakam and @Appium_Master (Both are my accounts)

Whatever the test I executed using selenium grid was with Native apps/Hybrid apps. So Just now I tried with chrome browser and I was able to successfully execute the single scripts on both the devices Sequential one after another.
[I'm using Galaxy Note 2 and Galaxy Note 3 (both are in Android kit version)]

Sequential execution i am able to do. But the question is that can test scripts be executed in parallel?

As per my observation parallel execution is not happening as chromedriver was created when executing on one of the mobile, until this process is killed or exited launching of chrome on another mobile was not possible.

Please let me know if this observation is correct?? also can you help with overcoming this issue?

Thanks and regards,

@Srikanth_Katakam , could you please solve this if you know .!! Thank you in advance.

Hi @bhaskar ,
'Cannot find module' is a node error, not an appium or grid related error.
If you are using AppiumForWindows, you must execute "node node_modules/appium" from AppiumForWindows folder instead of "node .".

Hi @rgonalo.. Many Thanks for your reply.!!! I'm not using Appium for windows(.exe)... i have installed it through command prompt by node.js..like " npm install -g appium "

Appium 1.34
Windows 7

Then you must use "appium --nodeconfig ..."

bhaskar · Feb '15

I tried your file and it worked fine from my side. I can confirm that it is neither a problem with Appium nor with your configurations.

For some unknown reason your keyboard might be inserting the wrong characters, so please download the following file node.txt133), change the extension from .txt to .json (as the website here forbids uploading .json files) and try again.

Also to make sure that there is no syntax error with your json file, you can use the following website: http://www.jsoneditoronline.org/39
