battery test (automator workflow script)

[ressac]

I saw in the news this...
http://www.macobserver.com/tmo/article/os-x-battery-life-analysis-from-snow-leopard-to-mountain-lion

so i want to make this test on my own macbook pro 13", but i don't know how to make this automator workflow script file

To simulate a moderate workflow, we use a custom Automator application, which is the same as in our previous tests. Our automatic workflow consists of the following steps:

1) Open TextEdit, pause 10 seconds

2) Open Safari and navigate to a content-heavy website (macobserver.com), pause 20 seconds

3) Navigate to a second content-heavy website (cnn.com), pause 20 seconds

4) Open Mail, pause 10 seconds to allow any messages to download

5) Close all open applications

6) Log a time stamp to a text file
7) Repeat

Who can make this script automator workflow?
I want to test on my Mac..
