How to edit /etc/fstab properly for network drive?

I'm trying to automatically mount a network drive at startup by editing /etc/fstab but doesn't work. If I execute this líne, sudo mount.cifs //192.168.0.67/test /home/pi/test -o username=myname,password=123 it works great. But I don't know how to properly write the same in /etc/fstab.
