I'm not aware of standard tests (and if anyone know some, please let me know).
Here is how I did my tests for zlib, hextile and tight [1].

I installed a kubuntu with qemu and hacked SDL_viewer example from
libvncserver to be able to select an encoding (I can give you the line
to modify if you want).
Then launched (several times) qemu with ./qemu  -m 512 -hda
kubuntu.img -vnc :0 & sleep 0.5; ./SDL_viewer 127.0.0.1

On another term I launch tcpdump -i lo0 -nvv port 5900 | python
tcpstat.py > dump.csv (but you can use wireshark, etc ...)
