Tests

This is running on xcaltst@max-exfl-cal002

I have added this content in ~/.config/systemd/user/calephant.service Then

• systemctl --user daemon-reload
• systemctl --user enable calephant.service
• systemctl --user start calephant.service

I have added aliases as well for calephant

# calephant systemd management
alias calephant-up='systemctl --user start calephant.service'
alias calephant-down='systemctl --user stop calephant.service'
alias calephant-status='systemctl --user status calephant.service'
alias calephant-logs='journalctl --user --pager-end -u calephant.service'

Additional Notes

Before merging and deploying to production I have to set on a common structure on the directory and venv name. Currently they different between production and test
