**I am using pytest for automation of a website for the parallel execution of test cases I am using xdist where n=5 but when I try to run all test cases with marker 'all' it gives me the above error. Can anyone help me how to solve it. **

@alex can you help me in solving it.

This seems like an issue with your tests or environment, and not a bug in pytest:

 selenium.common.exceptions.TimeoutException: Message: timeout: Timed out receiving message from renderer: 300.000

I'm thus converting this to a discussion.

what would you say about this? which is mainly causing my test cases to be failed. These test cases are in bulk. so when try to run all of it after 20 or 30 % completion it display the same error.

[saifali-pf]

@The-Compiler Can you please guide me regarding this error?

[The-Compiler]

what would you say about this?

That's just pytest-xdist re-raising the actual exception so that it can be transported back to the main process. The actual issue is the selenium timeout.

Can you please guide me regarding this error?

No, sorry, I've never used Selenium.

[saifali-pf]

Thanks for your response. I will try to fix it according to your statement of the timeout issue. And will let you know if found any further issues. Much appreciate your response to it.
