Can you give us some information about your operating system? Did you build this version of python yourself? Assuming so, how did you build it? Please show us the header you see when starting this version of python. How are you invoking this test?

pythongh-83994, pythongh-132843: Fix and improve test_ioctl
serhiy-storchaka commentedon Apr 23, 2025
You can reproduce this on Linux by running tests with
setsid.It seems that the tests were always skipped on CI and buildbots because /dev/tty was not available or not attached to the process. But one test (test_ioctl_set_window_size) did not depend on this and could be run. #132848 makes only tests that depend on /dev/tty be skipped.
