test_qt.service contents is as follows
```
[Unit]

After=weston.service
[Service]

EnvironmentFile=-/etc/default/test_env
ExecStart=/home/root/test_timer -platform wayland-egl
TimeoutSec=20000
[Install]
WantedBy=multi-user.target
```
test_env
···
#!/bin/sh
XDG_RUNTIME_DIR=/run/user/0
if test -z "$XDG_RUNTIME_DIR"; then
XDG_RUNTIME_DIR=/run/user/0
if ! test -d "${XDG_RUNTIME_DIR}"; then
mkdir --parents "${XDG_RUNTIME_DIR}"
chmod 0700 "${XDG_RUNTIME_DIR}"
fi
