Here's a little Introduction to WATIR/Basic Training presentation and simple exercises I put together a while back. I thought I'd post it in case anyone else could get some re-use out of it.
I use this when I hold training sessions for developers in my company on Watir. I usually take about 1.5 to 2 hours to walk through the presentation, do some simple exercises as a group, and answer questions.
The attached 5 exercises walk the trainee through the following:
1- Opening and manipulating an IE window
2- Interact with some form elements on a simple login page,
3- Re factor the login script, Adding some page content validation to the login script.
4- Re factor the login script to use a method/function.
5- create a simple unit test case using the login method.
Note: these exercises won't run out of the box, and, for the best learning experience, you should customize them for each training session to work with the application the developers are creating or are at least familiar with. (people like useful examples
