Coding locally and testing on a remote server, is often troublesome.
For example, forgetting to update the server results in useless tests.
Easiest way is to automatically synchronize the wanted folders.

For Windows I use WinSCP, which allows to easily to keep a remote directory updated.
For Linux, there is a script from Lukas Meyer:

• livesync
  #!/bin/bash
#infinite loop, we can end the script hitting ctrl+c#define options as array
  declare -a options#set first empty position with new value
  options[${#options[*]}]=”site1″;
  options[${#options[*]}]=”site2″;
  options[${#options[*]}]=”site3″;while [ true ] ; do
  #we create a menu to select which site to update
  select site in “${options[@]}” ; do
  #based on the selection, the syncscript with the proper arguments is called
  case ${site} in ${options[0]})
  syncscript /site1/local/folder server_ip1 username1 password1 /var/www ;
  ;;
  (site2)
  syncscript site2/local/folder server_ip2 username2 password2 site2/remote/folder ;
  ;;
  (site3)
  syncscript site3/local/folder server_ip3 username3 password3 site3/remote/folder ;
  ;;
  esac;
  done
  done
• syncscript
  #!/usr/bin/expect -f
#the she bangs line, to find out the path to expect on your system, type "which expect" on the shell#we get the command line arguments
  set localfolder [lrange $argv 0 0]
  set server_ip [lrange $argv 1 1]
  set username [lrange $argv 2 2]
  set password [lrange $argv 3 3]
  set remotefolder [lrange $argv 4 4]#this disables the timeout, so our script waits as long as it takes for the transfer
  set timeout -1
  #this calls rsync based on the command line args
  spawn rsync -r -a -v $localfolder $username@$server_ip:$remotefolder –exclude .svn
  #this avoids that if the output is to large, the earlier bytes won’t be fotgotten
  match_max 100000#we’re expecting the password prompt, we use a pattern so it can be anything that contains password: or Password
  expect “*?assword:*”
  #after we get the prompt we send the password
  send — “$password\r”
  #then we send a newline to make sure we get back to the command line
  send — “\r”#wait for the end-of-file in the output
  expect eof
