Phil came into my office, and flopped down into the comfortable chair across from my desk. He looked depressed and worried. “Hey, Phil,” I asked him tentatively. “You look like something’s bothering you. What’s up?” His brow furrowed. “I don’t know. I just don’t know. Sometimes I feel like people think of me as nothing more than a literary device.” I usually don’t like fiction writing in the form of … Read more
Rikard Edgren, Henrik Emilsson and Martin Jansson collaborate on blog called thoughts from the test eye. In a satirical post from this past summer called “Scripted vs Exploratory Testing from a Managerial Perspective“, Martin proposes that “From a managerial perspective without knowing too much about testing, your sole experience comes from the scripted test environment…” But I think that from a managerial perspective, there is another place you could look … Read more
In this blog post, my colleague James Bach talks about logging and its importance in support of exploratory testing. Logging takes care of one part of the accountability angle, and in an approach like session-based test management (developed by James and his brother Jon), the test notes and the debrief take care of another part of it. Logging records what happened from the perspective of the test system. Good logging … Read more
Excellent testers recognize that excellent testing is not merely a process of confirmation, verification, and validation. Excellent testing is a process of exploration,discovery, investigation, and learning. A correspondent that I consider to be an excellent tester (let’s call him Al) works in an environment where he is obliged by his managers to execute overly structured, highly confirmatory scripted tests. Al wrote to me recently, saying that he now realizes why … Read more
Yesterday I set up a thought experiment in which we divided our day of testing into three 90-minute sessions. I also made a simplifying assumption that bursts of testing activity representing some equivalent amount of test coverage (I called it a micro-session, or just a “test”) take two minutes. Investigating and reporting a bug that we find costs an additional eight minutes, so a test on its own would take … Read more
If you’re a tester, you’ve probably been asked, “Why is testing taking so long?” Maybe you’ve had a ready answer; maybe you haven’t. Here’s a model that might help you deal with the kind of manager who asks such questions. Let’s suppose that we divide our day of testing into three sessions, each session being, on average, 90 minutes of chartered, uninterrupted testing time. That’s four and a half hours … Read more
How is it useful to make the distinction between testing and checking? One colleague (let’s call him Andrew) recently found it very useful indeed. I’ve been asked not to reveal his real name or his company, but he has very generously permitted me to tell this story. He works for a large, globally distributed company, which produces goods and services in a sector not always known for its nimbleness. He’s … Read more
At a couple of recent conferences, some people have asked me about one “maturity” model or another. As one of the few people who has read the CMMI book from cover to cover, here’s what I think: In process-speak, the notion of maturity is backwards. A mature entity, in biology, is one that can survive and thrive without parental support. A mature being is one that has achieved an age … Read more
Several years ago, around the time I started teaching Rapid Software Testing, my co-author James Bach recorded a video to demonstrate rapid stress testing. In this case, the approach involved throwing an overwhelming amount of data at an application’s wizard, essentially getting the application to stress itself out. The video goes on for almost six minutes. About halfway through, James asks, “You might be asking why I don’t stop now. … Read more
Some of this posting is based on a conversation from a little while back on TestRepublic.com. If anyone has a problem with “test estimation”, here’s a thought experiment: Your manager (your client) wants to give you an assignment: to evaluate someone’s English skills, with the intention of qualifying him to work with your team. So how long would it take you to figure out whether a Spanish-speaking person spoke English … Read more
