Browser closes automatically after the tests without calling quit or close ()

[Satish]

I'm trying to automate selenium with python on windows 7. Browser - Chrome.

It is strange that my browser automatically closes after the test . I don't have quit() or close()  in my code.

Can someone advise on this?

Hi,

The Chrome driver will stop its service once the test ends.

To stop it from happening, you can use the below code. 

from selenium.webdriver import ChromeOptions, Chrome

opts = ChromeOptions()

opts.add_experimental_option("detach", True)

driver = Chrome(chrome_options=opts)

Thanks.

Hey Sai,

That worked but my tests won't run any more due to below error . Is it some compatibility issue with driver and browser? It was running earlier .

selenium.common.exceptions.WebDriverException: Message: unknown error: call function result missing 'value'
  (Session info: chrome=70.0.3538.102)
  (Driver info: chromedriver=2.33.506120 (e3e53437346286c0bc2d2dc9aa4915ba81d9023f),platform=Windows NT 6.1.7601 SP1 x86_64)

Hi, 

Check whether you have given sufficient wait time in code..

Yes, I am thinking it will be a compatibility issue, please try to update the driver and the browser to latest version and see if that helps.

Thanks.

Tried that and still the same.

How to resolve this?

I have also tried the same but with win10 machine,

In my code i have commented driver.quit to check this, after the completion of test still the test is in running mode until i press terminate button(red button in console) which closes the browser automatically.

Do you have any code like driver.stop_Client() it will also try to close the session i believe.
