Critic Thinking

It's not a typo, the title. I've been thinking about how - like a professional critic - a professional tester frequently needs to bridge the gap between the connoisseur and the consumer, to take the desires, constraints, needs, sensitivities and complaints of both into account when trying to make sense of and assess a product.

I used to spend a lot of time on music: I'd listen to tens of new records every week and go to gigs all the time. I could, and did, talk about subtleties of a drum sound, listen to tracks because of who produced them, argue about whether this or that 12" single was dark acid techno or acid dark techno or dark/acid techno or whatever. I would play records because I appreciated technical aspects of the sounds on them as much, if not more than, the music. I would deliberately seek out ever more subtle or challenging sonic experiences, such as  Dog Pound Found Sound (which I actually played on the radio). Or records made by someone linked to someone who had once played with someone I had once liked a record by. I was a connoisseur.

My wife often thought the records sounded the same, or were simply crap. What she did like she just knew she liked, usually a decision based purely on how what she heard made her feel. Any aspect of how or why or where it was made was irrelevant to her. She was a consumer.

When I wrote about or broadcast a piece of music I, as the critic, would attempt to respect the respect the depth of knowledge and zealousness of the connoisseur and try to place records in some kind of context that would make sense to the consumer while at the same time not compromising the integrity of either party. Similarly, when testing, it can be important to bear in mind both the internalised view of the product and the end user view (or rather views) of it. Being able to do this, and trade them off against one another, is a skill, a craft, an art.

One example; here's the bones of a particular kind of conversation I've had many times over the years:
Person 1: When I do A, the product does B. This was a surprise to me.
Person 2: Ah, yes. It does B because of X, Y, Z. It's how we were asked to do it. It's expected.
Person 1: But as far as I can see, A has nothing to do with X; Y is not visible at this point; Z is a concept that only exists in the product internals.
Person 2: Yes, but that's how it was requested and implemented. It's expected.
Person 1: But when I do A, getting B looks wrong when all I have to go on is X.
Person 2: Yes, but given how we coded it - which was according to the requirement - it's expected.
I have played both roles in this going-nowhere-fast dialogue. When I was a software engineer - or, to avoid offending actual software engineers, when I wrote the code - I was more often Person 2, a specialist with detailed knowledge and perhaps an entrenched position. (The specification as a shield. Discuss.)

As a tester I have sometimes found myself as Person 2 when discussing a feature I'm working on with someone who isn't working on it. When I've invested time, effort and emotional capital I can become defensive; closer to the end of the cycle I can become more of an apologist for flaws. Even on a feature I feel free to criticise myself - and probably have done at length - I can feel uncomfortable with others' criticism of it. Even when I agree with the criticism I can feel obliged to justify the observed behaviour.

In my experience the Person 1 role seems to come naturally to those with less baggage or, perhaps better, background. They can be gloriously indignant at the slightest provocation, focussed on the detail that offends them to the exclusion of all others and unreceptive to any justification. It seems to be a natural trajectory that, once they've been around the product for a while and inevitably been inducted into the world of Person 2, it becomes hard for them to decline its comforting, if stifling embrace. (The specification as blinkers. Discuss.)

At the other end of that trajectory, I find that testers with more experience can tend to become more comfortable maintaining both Person 1 and Person 2 positions simultaneously, expressing both without prejudice, balancing them out in context. As it happens, I don't think experience is necessary for this duality, but I do think self-awareness is and that frequently comes with experience.

So, what kind of person will you be today? A connoisseur, a consumer, a critic?

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 .

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...
