Overview

Package testpty provides test-only helpers for isolating package test binaries inside owned PTYs so terminal state changes cannot leak to the caller's controlling terminal.

func MaybeReexecOwnedPTY

func MaybeReexecOwnedPTY() (handled bool, code int, err error)

MaybeReexecOwnedPTY re-execs the current test binary under an owned PTY so package tests never inherit the caller's controlling terminal for resize/raw operations. It returns handled=true in the parent process, along with the child exit code to propagate via os.Exit.
