//! This test builds and runs a basic UEFI application on QEMU for various targets.
//!
//! You must have the relevant OVMF or AAVMF firmware installed for this to work.
//!
//! Requires: qemu-system-x86_64, qemu-system-aarch64
//! OVMF/AAVMF firmware
//!
//! Note: test assumes `/uefi_qemu_test` exists and is a self-contained crate.
//@ only-uefi
