What is Exploratory Testing (ET)? I am asked this every once in a while and I hear a wide range of ideas as to what it is. This is one of those topics where Wikipedia doesn't really help much.
For some, ET is just "good" testing and the reason we say "exploratory" is to distinguish it from bad testing practices. Unfortunately, bad, lazy, haphazard, thoughtless, incomplete, and incompetent testing is quite popular. I won't go into the reasons or supporting evidence for this disgraceful blight on the Software Development industry at this time. Suffice it to say, I don't want to be mixed in with that lot either, so I am happy to describe what I do as something different - something that is far more successful and rewarding when done well.
Okay, so if ET = [good] testing, what is testing then? According to Cem Kaner, "software testing is a technical investigation conducted to provide stakeholders with information about the quality of the product or service under test." This definition took me a while to absorb but the more I thought about it the more I found it to be a pretty good definition.
If you ask Elisabeth Hendrickson, she would say that "a test is an experiment designed to reveal information or answer a specific question about the software or system." See, now I really like this definition! I studied Science in university and I love the way this definition reminds me of the Scientific Method. The more I learn about testing software, the more I find similarities with doing good Science. (By the way, if you want to learn more about how to do good testing, I highly recommend you read up on the Scientific Method. So much goodness in there!)
So, is that all there is to it? Testing = Science, blah blah blah, and we're done? Um, well, no, not really. ET has its own Wikipedia page after all!

The Future(s) of Software Testing
This topic keeps coming up in various discussions so here are some thoughts on what I think a future may hold for us one day. What does it mean to predict the future? Does it mean it is inevitable? If it is something appealing, maybe it is something we can work towards.
What does it mean to talk about the Future of Software Testing without talking about "Quality" (whatever that is)? I believe that Testing is a means to helping you attain the desired quality but that on its own it is not an indicator of what the delivered quality will be. I think it is fair to speculate on the practice of Testing in isolation of the idea of Quality. Just like it is fair to speculate on the kind of vehicles you use for travel without saying it is a clear indicator of the quality of the journey.
When it comes to predicting the future, how far ahead do we look? It used to bother me that H.G. Wells chose to go 800,000 years in the future in his famous work, The Time Machine. Some authors go 100 years or even just 5 or 10 to tell their tale. I will not be writing about what will happen in 5 years time and I really hope it doesn't take 100 years. I don't know how long some of these events will take to manifest. I do have some idea of 'markers' that we may see along the way though.
When it comes to Software Testing, two thoughts jump immediately to mind: 1) Software Testing is an inseparable part of the creative Software/Solution Development process; and 2) there will be many different possible futures depending on how you do testing today. Put another way, there is no one right way to solve a problem, and creating software is a complex problem-solving activity performed in shifting organisations of human interaction so there are many ways to do it. In my opinion, the technical 'fiddly bits' like code, tests and user documentation pale in comparison to the difficulty of those two primary challenges: (1) solving the real problem, and (2) working with others to get the job done.
When we ask what is the future of software testing, we are really asking what is the future of software development. So what will Testing look like in the future? Well, what does Testing look like today? What does Development look like today?

Radiating Testing Information - Part 1
This topic is one that I have been asked about many times over the years and I am long overdue for a detailed discussion of it. Back in 2006 I presented an Experience Report at the STiFS workshop in New York titled "Low-Tech Testing Dashboard Revisited." The content of that presentation will be in Part 2. To quote "The Do-Re-Mi Song" from the movie The Sound of Music, "Let's start at the very beginning, a very good place to start."
I attended the StarEast conference in 1999 and there was a talk by James Bach titled "A Low Tech Testing Dashboard." This presentation clicked with me as I was managing several test teams at the time and it addressed a problem that I felt was important. I have used this communication tool many times ever since. If you are not familiar with it, I suggest you read through the PDF slides on the Satisfice web site before you continue. Go ahead. I'll wait.
In this review I will cover some of the who, what, where, when, how and why of the Low Tech Testing Dashboard (LTTD) through examples from past projects I have worked on. I expect your context is different, so my hope is that these examples may help you think about how you might apply this communication tool on your project.
