test_ptyprocess.py terminating early due to child process exit
niyas-sait opened this issue · comments
I've been trying to port pywinpty for windows on arm64 platform and while trying to run the unit tests (using python runtests.py or pytest) the tests terminate early during executing tests from test_ptyprocess.py.
I think this happens when we try to terminate a forked child by os.kill or an exit statement to the application.
I've tried this on the x64 windows as well and I see the same behavior. I've tried powershell and cmd and observed the same behaviour for both.
I don't know if this is an issue with the test framework or I am doing it wrong.
OS: Windows 10
Platform: ARM64
Python Version: 3.10
PyWinPty: (0d681680)
Terminal: Powershell and Cmd
@andfoy Thoughts ?
Looks like the test has been progressing it is just that I don't get to see the output on the terminal anymore. If I pipe the output to a file then I can see that tests are all passing as expected.

This is weird, since standard streams are being recreated in case the parent has redirected them:
Did the error occur on a cmd prompt?
Did the error occur on a cmd prompt?
yes, I've tried both cmd prompt and powershell. Same behaviour observed
@nsait-linaro, do you know if this issue still occurs with the latest release?
