Tuesday November 6th, Jim Priest will present on Selenium IDE and ANT. I am a big fan of both of these tools for Rapid Development. I was out of town when Jim gave his initial ANT presentation so I am pleased he is giving an encore.
Selenium is a framework for testing web based UI. ANT is a framework for scripting and automation. Both are very easy to learn and extremely powerful. Proper use of Selenium and ANT will increase the quality of your production software, reduce repetitive work and save you time. You need to have these tools in your tool chest.
BTW, If you do not know Selenium, watch this 3 minute clip.
