`import pty` at module scope pulls in `termios`, which does not exist on
Windows. That raised ModuleNotFoundError during *collection*, so pytest
aborted the whole module with
Interrupted: 1 error during collection
before any skip marker could take effect. The single PTY-dependent test
was already correctly marked `skipif(sys.platform == "win32")` — the
import crashed ahead of it and took the module's 13 other, entirely
platform-agnostic tests down as collateral. Windows contributors got zero
gateway coverage and, worse, a collection error that masks real failures
in any batch that includes this file.
Two changes:
- Move `import pty` into the `stdin_is_tty` branch that actually uses it
(the sole `pty.openpty()` call). Nothing else in the module needs it.
- Skip `test_systemd_install_checks_linger_status` on Windows. It drives
`_systemd_linger_enabled()` -> `os.getuid()`, which does not exist on
Windows; the production helper is annotated
"windows-footgun: ok — POSIX systemd helper, never invoked on Windows",
so the test is Linux-only by nature. It was previously hidden behind
the collection crash.
POSIX behaviour is unchanged: both guards are `skipif(win32)`, inactive
off Windows, and the local import resolves exactly where the module-level
one did.
before (Windows): 0 collected, 1 collection error
after (Windows): 14 collected, 9 passed, 5 skipped
