Testing is a Medium

In a few days I will be giving a presentation to the local Agile/Lean Peer 2 Peer group here in town. The group has a web site - Waterloo Agile Lean, and the announcement is also on the Communitech events page.

I noticed the posted talk descriptions are shorter than what I wrote.  The Waterloo Agile Lean page has this description:

"This session will introduce the basic foundation of Exploratory Testing and run through a live, interactive demo to demonstrate some of how it’s done. Bring your open minds and questions and maybe even an app to test. If ET is new to you, prepare to get blown away!"

The Communitech page has this description:

"Exploratory Testing is the explosive sound check that helps us see things from many directions all at once. It takes skill and practice to do well. The reward is a higher-quality, lower-risk solution that brings teams a richer understanding of the development project.

This is what I submitted:

"Testing is the medium in which solutions are developed. The value of our delivered solutions depend upon how well we understand and utilize that medium. We can fly straight like an arrow or explode outwards like a spherical sound wave.
Traditional automated TDD "checks" help us fly straight in the direction we choose. Is it the right direction though? How do we know? Are you sure?

This blog post is *not* about the differences in session descriptions. (In fairness, I really should learn to keep it to one paragraph. I hope to get better at writing session descriptions - it'll come with practice.) Reading the last one first, I can't help think that a bit of context is missing from the two posted descriptions for the final "blown away" statement. That is, that phrase comes from the sound wave analogy and not from some arrogant expectations I have for my presentation abilities. If I had known the descriptions would be shortened, I would have at least changed that sentence.

This blog post is about the idea that I try to convey in the first sentence that is unfortunately missing from both posted session descriptions: "Testing is the medium in which solutions are developed."

Software Development is a creative process. It is the intersection of people, skills, tools and experimentation to solve a people-problem with technology. As Jerry Weinberg once said: "all problems are people-problems." Therefore all developed products or services are "people-solutions."

Perhaps the main thought with "Testing is a medium" is that you cannot (successfully) solve any problem without trying to understand what the problem is in the first place. e.g.: Who is it a problem for? Where? When? How? -- these are all *Testing* questions. When you deliver a solution, you check it with something like: "how does this meet your needs?" -- again, another question.

Software Development begins and ends with questions. Somewhere in the middle of the creative development process are more testing questions. Lots of different kinds of questions, tests and checks depending on the people, skills and risks involved in developing each particular solution. One could say that Software cannot be developed without Testing.

Have you tried? Have you ever been on a project where you didn't first ask the customer what the problem was? You didn't check to see if what you are building is working towards that design? Or you didn't ask the customer afterwards if what you delivered meets their needs? How did that work for you?

If one cannot hope to hit the target without checking many different things, why is Testing often given so little attention or recognition on development projects? Too few individuals try to develop expertise in the Testing field to elevate their contributions to the development effort.

Anyone may ask a question. That doesn't make you an "expert" in asking questions. My 10-year-old son uses scissors to cut things, but that doesn't mean I want to let him cut my hair! Everyone I meet feels they know what Testing is. Okay, then why do so many projects fail?

So, what does it take to become really good at Testing? It appears to be somewhat important for the success of most software projects. Maybe it's time to take a good look at Software Development through the medium of Testing. How might you look at things differently then? What skills or knowledge would you want to learn more about? Who do you think should be involved?

I won't be talking about any of this stuff on Tuesday though. After all, it's not in the session description. =)
