Testing Multiple Apps in One Device - First session is terminated when second starts

Hello,
I’m trying to use one device and I would like to test two different apps on one device. (Android)
I checked through documentation and according to that configured the necessary settings for appium servers and also for sessions.
https://github.com/appium/appium-uiautomator2-driver#parallel-tests as it states here, for parallel tests systemPort capability should be given differently.

As it is stated here, I also changed Bootstrap port for 2 server instances.

Here is my configuration for Appium Servers: (Started via Appium Desktop App)

Appium Inspector Configurations:
First session is configured to work on 127.0.0.0.1/4724 with systemPort 8202 and second is 127.0.0.0.1/4734 systemPort 8212

1st session: First App

Caps:
    {
      "platformName": "Android",
      "appium:deviceName": "Nokia G20 new",
      "appium:udid": "PT99653AA11B2600974",
      "appium:appPackage": "app_package_here",
      "appium:automationName": "UiAutomator2",
      "appium:appActivity": "app_activity_here",
      "appium:unlockType": "password",
      "appium:unlockKey": "1111",
      "appium:newCommandTimeout": 7200,
      "appium:app": apk_path_here",
      "appium:nativeWebScreenshot": true,
      "appium:clearSystemFiles": true,
      "appium:systemPort": 8202,
      "appium:fullReset": false,
      "appium:noReset": true
    }

2nd session: Second App

Caps:
    {
      "platformName": "Android",
      "appium:deviceName": "Nokia G20 new",
      "appium:udid": "PT99653AA11B2600974",
      "appium:appPackage": "different_app_package_here",
      "appium:automationName": "UiAutomator2",
      "appium:appActivity": "different_app_activity_here",
      "appium:unlockType": "password",
      "appium:unlockKey": "1111",
      "appium:newCommandTimeout": 7200,
      "appium:app": apk_path_here",
      "appium:nativeWebScreenshot": true,
      "appium:clearSystemFiles": true,
      "appium:systemPort": 8212,
      "appium:fullReset": false,
      "appium:noReset": true
    }

Issue description:
When I start the 1st session, everything is fine. Session starts.(2nd server instance already terminates! Why??) Then I’m trying to start 2nd session with a different app. At this point, 1st session got terminated by itself and of course, I can’t take any actions.

Appium Server and App Inspector logs when the problem happens:

What is the problem here? Is it not possible to open up two apps on one device in different sessions?

I also tried different remote ports, localhost address, bootstrap ports and so on. Nothing worked.

Note:

  • Appium Desktop (Server) App version: 1.20.0
  • Appium Inspector version: 2022.9.1

Kind regards,

It will not work on same phone. Parallel means each test with own device.

Thanks for the answer!
So, there is no way to test different apps(with different appium sessions) on 1 device?

No. But you can start other app during test or you can close driver and start it again with other app.

I see. What I was looking for more like this case:
One device opens up application A and application B. Something is done from app A and then, I can check out some values from other app B.

I thought it was possible at same time. But as you said, only way to do that on 1 device is:
open app A, do stuff
closing session for app A, open app B, do the check,
closing session for app B, open app A, do stuff again, and so on…

I understood correctly right?

correct. with last Appium you can keep apps open without restart while switching driver between them!

it may be important for your test.

Thanks a lot for your help! I will try
