During the Rapid Software Testing course James Bach advised to name things. If I cannot tell, what I am doing, my boss would think: “What the < beep > is he doing?”
So after the course I came up with the DUMB heuristic. This heuristic I use frequently during my testing.
Suppose my boss asks me how the testing goes. My answer could be: “I do uh my best.” A busy tester is always good, but if I am too busy things might go wrong. All my energy and brain power are focused on the work at hand. I forget to think. That’s DUMB.
When I figured out my heuristic, I had to find some smart explanation for this abbreviation. It became Do Uh My Best. Most heuristics are acronyms or lists of words. In turn every word is explained in detail. You know: turned upside down and shaken. But I just stick to the abbreviation.
Some readers have a good reason to ask. So hold on. The emphasis of the heuristic is on Uh. This is an alarm bell. Hesitation is a sign, that too much is going on in my head. I might forget to pay the deserved attention to the real problem.
This following discussion I had several times with my scrum master:
“I am writing test cases.”
“Why do you make test cases?
How often will the tests be executed? Who will maintain the test cases?”
So I was doing my best. And my scrum master got an Uh out of me.
He let me reflect on my work. What was I doing? And why?
Many test heuristics I know are acronyms. Some I do use. The S in SFDIPOT stands for Structure, how is the application under test built? So which components do I have to test? Etcetera.
If I apply this to DUMB then I would get things like: Do is the activity I am involved at that moment. It can be taking notes in my test charter or just thinking. Etc. Etc. The only thing I need on that moment is a short reminder to reflect on my work. DUMB. One syllable. Keep it sweet and short.
When do I use this heuristic? If there is a lot of work to do. When I have hours of straight testing ahead, I can go in my little cocoon and do something testy and something nice comes out. Tadah.
What about the focus and defocus stuff? Most of the time I use this when I got stuck. What can I do now? Let’s take a step back. Now I see the big picture. I figure out at a high level. Let me zoom in.
The point is, that doing my best is equal to doing stuff which is in front of my nose. I just pick it up and start running. Maybe I get it done today or this morning. Completely forgetting to ask for the reason. And that is DUMB. NOK?
When I was writing this blog, something hit me in the face. That was my imaginary hand palm. This so called heuristic is maybe already known under another name or in another way. Like a proverb.
And yes Madam within a few minutes the following proverbs came in my mind:
Eile mit Weile
Easy does it
A day later followed by
Haastige spoed is zelden goed.
So why am I not using proverbs to keep my testing right? It is too long. Maybe a short heuristic could be useful.
“My scrum master would say something like Does it help?
This is really STUPID which stands for Some Thing …. I Do. UP are two words, so ….
Do I have to figure this out? WHY?”
“We Hear Yes.”
“Good In Real Life Software”
“Graphic Userinterface You See”
“People Lik E A Software Errooor”
“Co Herent Entertaining Erroneous Random Synthesis”
So you are a mindful reader. Congrats. Here is the bonus.
Why did I not throw this blog post in the waste bin? People already thought about it and distilled their experiences to proverbs.
It is about my thought process. I do not want to stop thinking. Once in a while I discover that other people already have figured it out. Sometimes I find something new. But apart of discovery of new thingies it is about thinking thingies through. Getting better to verbalise my thoughts and explain them to you the reader.
That was what I forget a while ago. Thanks for the attention.

When I Do Uh My Best, System 1 is operating. More information about System 1 can be found in this blog post.
WYSIATE stands for What You See Is All There Is. If I am too busy, I forget to look for other relevant information as mentioned in Thinking Fast and Slow.
The Lindy effect is about using knowledge especially from books. Thinking Fast and Slow is quoted for years by some testers. If a book is relevant for 5 years, it will probably remain relevant for another 5 years.
