A tester's screen saver
When man stepped on the moon, the cost of being on the surface and experimenting was a Million US Dollars a second in 1969.
Many projects that we work on today are as critical as the one above, not in terms of the cost of the test but the cost of missing a test, which matters to the client or affects the end user or the organization to whom you deliver your services. It is my opinion that the definition of "complete testing" many testers have, isn't convincing test experts or philosophers of testing. Hence it seems to be less plausible if someone says; I have tested this completely. It is interesting to note that some testers, in my experience have been using this knowledge of , impossibility of complete testing, to defend their work when questioned about a bug that they failed to find.
Investigative scientists and data collection team at NASA used guideword heuristics to maximize value of running test or observation at the cost of One Million US dollars a second. Refer to page 52 of Rapid Software Testing Appendices for more information.
Reading that would motivate a passionate tester to maximize value for the project he is working and would work in the future. The concept of thinking like an expert, enters a passionate tester mind on reading such articles.
It's time you realize, the importance of heuristics for testing a product better than what you have been doing so far, if you haven't been thinking about heuristics.
Now, all this is fine but who is going to help you each time to remember some of the most important heuristics that might help you to test in a way that makes you thank the heuristics and the people who came out with it?
It's none other you, dear passionate tester.
I like to offer a help to all those passionate testers who would want to use heuristics and think of cost v/s value when they test. I was delighted when I got the idea of offering a help and started working on it immediately. I am confident that most of you would like my idea and would recommend the usage of it to other testers too. My fingers remain crossed, though.
It's time for you to have a look at it. So download this www.satisfice.com/RST36.zip . Do not be afraid to run the exe, it's a screen saver that I have built for you, dear tester.
The idea will speak the rest and I stop here :)

Note: There were some issues with the screen saver earlier. Thanks to Venkat Reddy and Rosie Sherry for identifying the issue.
