Summary

The aim of this document is to provide a hands-on introduction to the use of the Ubuntu testing package to create new Ubuntu tests.

Prerequisites

ldtp and python-ldtp packages are needed to run the tests based on the testing library. Both packages are available in universe.

Installation

There are PPA packages for Intrepid. To install the library:

1. Add the following lines to your /etc/apt/source.lists:

deb http://ppa.launchpad.net/apulido/ubuntu intrepid main
deb-src http://ppa.launchpad.net/apulido/ubuntu intrepid main

2. $ sudo apt-get update
3. $ sudo apt-get install desktop-testing-library

Hello World!

Once installed we are going to create our first script to test Ubuntu. Our script will open the Gedit and will write the string "Hello World!" in the main gedit window.
