Run multiple tests on single device one after the other


I am trying to execute 2 tests on same Android device:
1)Calculators test on real device
2)Web Application on a real device

It executes first test perfectly, but when i am expecting that web application would be started once the calculator app is tested, I am getting error saying A new session could not be started and also says that a session already exists.

In my calculator test i have added driver.quit() in the @AfterMethod which closes the current session.

But the second test case which launches the webapplication i have re-initialized the AppiumDriver in @BeforeMethod. During this the tests are failing.

I am trying to use Appium with testng. All my tests are defined in Testng.xml and i have declared the tests not to riun in parallel.

Please suggest what needs to be done so that the tests start to execute one after the other on a same device.

Thanks and regards,

I am not sure whether this will work or not … but you can try starting your appium server with ‘session-override’ flag.

Again, not sure whether this will work or not.

Hi Pratyush,

I tried the above approach by setting the override-session. It Did not work. :frowning:

Is there any other approach to run test sequentially on a same device?

Thanks and regards,

I can’t think of anything else as I never encountered such issue. Can you post the exact logs of the failure so that others can also have a look at the issue?

My bad i had specified wrong port. It worked after changin the setting to override session.
Thank you Pratyush :smile:


Ahh! No problem! Cheers!

Try to run the testcases using testng framework.
if you are using testng framework, You can able to run the testcases one by one or parallel execution too without getting the session issues.

@Srikanth_Katakam: Thanks for the Videos but I have already done basic setup but for my project I need help with "How to launch Two apps one after the other in same session or even one after the other app should be fine.

Please let me know how to do it.

@yeruva7:- Please start you appium session with –session-override flag

node appium.js -a localhost -p 4568 --udid -bp 5557 --nodeconfig C:/json/nodeconfig_serial1.json –session-override
Create two classes with different app capability and test cases
facebook app capability
facebook test cases
calculator app capability
calculator test cases
Create testNG.xml like below
testng.txt (363 Bytes)
I hope it will work.

Can someone provide me code on how to override session with step by step.

Thanks in advance

@Jawlitkp :- session override is a flag, So you can set the flag while starting the appium server

  1. Open command prompt and Navigate to appium.js location
  2. node appium.js –session-override

You might to use Selenium Grid for this.

This might help you.

Hi Karthik,

I am using two android devices to test chrome broswer parallel, but if i open second instance of chromein the second device first instance is killing, though i am starting two different appium servers on two different ports.

command to start appium servers:
appium -p 4724 -bp 4726 -U EGxxxxxxxxx
appium -p 4723 -bp 4725 -U EGxxxxxxxxx

code: ( using ruby)
driver initilization:

def setup_appium_for_ne_on_android
Capybara.app_host = ‘https:/’
Capybara.server_port = 3001
Capybara.always_include_port = false

Capybara.default_selector = :css

Capybara.default_wait_time = 20
Capybara.default_driver = :chrome

def register_appium_android
Capybara.register_driver(:chrome) do |app|
appium_lib_options = {
server_url: “
all_options = {
appium_lib: appium_lib_options,
caps: desired_caps_android
}, all_options)

def desired_caps_android
platformName: ‘android’,
platformVersion: ‘4.4.2’,
deviceName: ‘Android’,
browserName: ‘Chrome’,
appActivity: ‘’,
appPackage: ‘’,

Could you help me on how to switch between the sessions without killing the previous session.

Hello Krishna,


I am new to appium- Mobile Automation, trying to make a simple mobile browser automation demo. My goal is to use appium with capybara along with Ruby, so that the appium inherits all capybara DSL. Please can you help me with any sample code, so that it can help me with start up. It will be a great help.
