You can do something like this:
on the current machine:
sudo dpkg --get-selections > server.selections

then copy the server.selections file to your test machine and run:
sudo apt-get update
sudo dpkg --set-selections < server.selections
sudo apt-get dselect-upgrde


That will install all packages that are on your current server on your
test server.
