Randy Rice is one of the people giving a tutorial for STAR West 2011 on Monday October 3rd. His tutorial is called Free and Cheap Test Tools. Since I'm enrolled in a different tutorial and not going to make it, I was curious to see if some of the tools he would be talking about were already posted online. Sure enough they are.
Unfortunately his site hasn't been updated in years: http://www.riceconsulting.com/cheaptools.htm (February of 2009 was the latest). Some of the software programs and/or websites have been shutdown like testersdesk.com.
I'd say at least 85% of the list is still worth looking at if you want to broaden your "testing tool horizons".
