My Goodness

The six presentations at CEWT #6 took different angles on the topic of good testing or good testers. Here's my brief summary of each of them:

Whatever good testing is, Karo Stoltzenburg said, it's not likely to be improved by putting a box around its practitioners. In fact, pretty much any box you care to construct will fit some other profession just about as well at it fits testing. Testers, like people in general, are individuals and it's in the combination of diverse individuals that we spread our risk of missing something and so increase our chances of doing the good testing we all want.

What makes a senior tester? That's the question Neil Younger has been asking himself, and his colleagues at DisplayLink. He shared some of his preliminary thoughts with us. Like Karo he wants to avoid boxes, or at least to reduce their rigidity, but against that there's a desire from some for objective criteria, some kind of definition of done that moves them from one box to another. A senior tester for Neil must naturally also be a good tester, and the draft criteria he shared spoke to the kinds of extras he'd expect such a tester to be able to provide. Things like mentoring, coaching, unblocking, improvement, awareness, and knowledge.

"Any kind of metric for testing that involves bug counts focusses on how we're sorting out the failures we find, not on team successes." Chris Kelly has seen metrics such as net promoter score applied to technical support and was musing out loud about whether metrics could be applied to testing. If they could, what should they look like? The discussion covered the difference between teams and individuals. Can a team member do good testing while the team fails? One way of judging success was suggested: ask the stakeholders whether they're getting what they want from your work.

In the limit, good testing would lead to perfect testing, Šime Simic proposes, perhaps a little teasingly. We aren't going to get there, naturally, but we can do things that help us along the road. In particular, he talked about knowing the mission, aligning the mission with stakeholder needs, testing in line with the mission, doing what we can inside the constraints that the project has, and then reflecting on how it went and how we might change next time in similar circumstances. Testing, he went on, should not exist in a vacuum, and it's unrealistic if not unfair to try to judge it apart from the whole development process. (References)

Because they have different needs it's perfectly possible, and indeed reasonable, for two people to have different views of the same piece of testing. When they are the test manager and the tester, however, it may lead to some problems. For the tester, on the project Helen Stokes and Claire Banks talked about, exercising the product was the primary requirement. For the manager, visibility of the work, and the results of the work, were imperative. "There's more to good testing than doing the tests" they conclude.

My own presentation was about how, assuming we could know what good testing is, it can be a challenge to know whether someone is capable of doing it. I talked about how this particular problem manifests in recruitment all the time, and about how testing skills can be be used to assess candidates for testing roles. (Slides)

Meet Me Halfway?

The Association for Software Testing is crowd-sourcing a book, Navigating the World as a Context-Driven Tester , which aims to provide responses to common questions and statements about testing from a context-driven perspective . It's being edited by Lee Hawkins who is posing questions on Twitter , LinkedIn , Mastodon , Slack , and the AST mailing list and then collating the replies, focusing on practice over theory. I've decided to contribute by answering briefly, and without a lot of editing or crafting, by imagining that I'm speaking to someone in software development who's acting in good faith, cares about their work and mine, but doesn't have much visibility of what testing can be. Perhaps you'd like to join me? --00-- "Stop answering my questions with questions." Sure, I can do that. In return, please stop asking me questions so open to interpretation that any answ...

The Best Programmer Dan Knows

I was pairing with my friend Vernon at work last week, on a tool I've been developing. He was smiling broadly as I talked him through what I'd done because we've been here before. The tool facilitates a task that's time-consuming, inefficient, error-prone, tiresome, and important to get right. Vern knows that those kinds of factors trigger me to change or build something, and that's why he was struggling not to laugh out loud. He held himself together and asked a bunch of sensible questions about the need, the desired outcome, and the approach I'd taken. Then he mentioned a talk by Daniel Terhorst-North, called The Best Programmer I Know, and said that much of it paralleled what he sees me doing. It was my turn to laugh then, because I am not a good programmer, and I thought he knew that already. What I do accept, though, is that I am focussed on the value that programs can give, and getting some of that value as early as possible. He sent me a link to the ta...

Beginning Sketchnoting

In September 2017 I attended Ian Johnson 's visual note-taking workshop at DDD East Anglia . For the rest of the day I made sketchnotes, including during Karo Stoltzenburg 's talk on exploratory testing for developers (sketch below), and since then I've been doing it on a regular basis. Karo recently asked whether I'd do a Team Eating (the Linguamatics brown bag lunch thing) on sketchnoting. I did, and this post captures some of what I said. Beginning sketchnoting, then. There's two sides to that: I still regard myself as a beginner at it, and today I'll give you some encouragement and some tips based on my experience, to begin sketchnoting for yourselves. I spend an enormous amount of time in situations where I find it helpful to take notes: testing, talking to colleagues about a problem, reading, 1-1 meetings, project meetings, workshops, conferences, and, and, and, and I could go on. I've long been interested in the approaches I've evol...

Don't Know? Find Out!

In What We Know We Don't Know , Hillel Wayne crisply summarises a handful of research findings about software development, describes how the research is carried out and reviewed and how he explores it, and contrasts those evidence-based results with the pronouncements of charismatic thought leaders. He also notes how and why this kind of research is hard in the software world. I won't pull much from the talk because I want to encourage you to watch it. Go on, it's reasonably short, it's comprehensible for me at 1.25x, and you can skip the section on Domain-Driven Design (the talk was at DDD Europe) if that's not your bag. Let me just give the same example that he opens with: research shows that most code reviews focus more on the first file presented to reviewers rather than the most important file in the eye of the developer. What we should learn: flag the starting and other critical files to receive more productive reviews. You never even thought about that possi...

How do I Test AI?

Recently a few people have asked me how I test AI. I'm happy to share my experiences, but I frame the question more broadly, perhaps something like this: what kinds of things do I consider when testing systems with artificial intelligence components . I freestyled liberally the first time I answered but when the question came up again I thought I'd write a few bullets to help me remember key things. This post is the latest iteration of that list. Caveats: I'm not an expert; what you see below is a reminder of things to pick up on during conversations so it's quite minimal; it's also messy; it's absolutely not a guide or a set of best practices; each point should be applied in context; the categories are very rough; it's certainly not complete. Also note that I work with teams who really know what they're doing on the domain, tech, and medical safety fronts and some of the things listed here are things they'd typically do some or all of.

Express, Listen, and Field

Last weekend I participated in the LLandegfan Exploratory Workshop on Testing (LLEWT) 2024, a peer conference in a small parish hall on Anglesey, north Wales. The topic was communication and I shared my sketchnotes and a mind map from the day a few days ago. This post summarises my experience report. Express, Listen, and Field Just about the most hands-on, practical, and valuable training I have ever done was on assertiveness with a local Cambridge coach, Laura Dain . In it she introduced Express, Listen, and Field (ELF), distilled from her experience across many years in the women’s movement, business, and academia. ELF: say your key message clearly and calmly, actively listen to the response, and then focus only on what is relevant to your needs. I blogged a little about it back in 2017 and I've been using it ever since. Assertiveness In a previous role, I was the manager of a test team and organised training for the whole ...

Not a Happy Place

A few months ago I stopped having therapy because I felt I had stabilised myself enough to navigate life without it. For the time being, anyway. I'm sure the counselling helped me but I couldn't tell you how and I've chosen not to look deeply into it. For someone who is usually pretty analytical this is perhaps an interesting decision but I knew that I didn't want to be second-guessing my counsellor, Sue, or mentally cross-referencing stuff that I'd researched while we were talking. And talk was what we mostly did, with Sue suggesting hardly any specific tools for me to try. One that she did recommend was finding a happy place to visualise, somewhere that I could be out of the moment for a moment to calm disruptive thoughts. (Something like this .) Surprisingly, I found that I couldn't conjure anywhere up inside my head. That's when I realised that I've always had difficulty seeing with my mind's eye but never called it out. If I try to imagine ev...

Why Question?

Questions are a powerful testing tool and, like any tool, can be used in different ways in different scenarios with different motivations and different results. A significant part of my role is generating questions and I will generally have a lot of them. I will rarely ask them all, though, and I've put a lot of time and effort into learning to be comfortable with that. A couple of examples: I was in a meeting this week where the technical conversation was too deep for me to give a perspective from a position of knowledge. I could have disengaged, but I didn't. Instead, I asked occasional questions, not wanting to derail the discussion or disrupt the flow. Some were detail questions, to help grow my understanding. Some were scoping questions, to help understand motivations. The one that really landed, however, was about the focus of the meeting. Although I couldn't contribute at a low level, I understood enough to suspect that we were not discussing the key problem tha...
