Example

from pytest_bluezenv import host_config, Bluetoothd, Bluetoothctl

@host_config(
    [Bluetoothd(), Bluetoothctl()],
    [Bluetoothd(), Bluetoothctl()],
)
def test_bluetoothctl_pair(hosts):
    host0, host1 = hosts

    host0.bluetoothctl.send("scan on\n")
    host0.bluetoothctl.expect(f"Controller {host0.bdaddr.upper()} Discovering: yes")

    host1.bluetoothctl.send("pairable on\n")
    host1.bluetoothctl.expect("Changing pairable on succeeded")
    host1.bluetoothctl.send("discoverable on\n")
    host1.bluetoothctl.expect(f"Controller {host1.bdaddr.upper()} Discoverable: yes")

    host0.bluetoothctl.expect(f"Device {host1.bdaddr.upper()}")
    host0.bluetoothctl.send(f"pair {host1.bdaddr}\n")

    idx, m = host0.bluetoothctl.expect(r"Confirm passkey (\d+).*:")
    key = m[0].decode("utf-8")

    host1.bluetoothctl.expect(f"Confirm passkey {key}")

    host0.bluetoothctl.send("yes\n")
    host1.bluetoothctl.send("yes\n")

    host0.bluetoothctl.expect("Pairing successful")

The test declares a VM setup with two Qemu instances, where both hosts run bluetoothd and start a bluetoothctl process. The Qemu instances have btvirt virtual BT controllers and can see each other.
