The Antics in Semantics

In his EuroSTAR 2015 talk, Iain McCowatt described an ongoing project which involves establishing testing principles for his teams, across projects. In a large organisation in a heavily-regulated environment such as his, this is a really significant challenge, but he described an interesting, pragmatic approach based on Simon Sinek's Golden Circle.

While discussing the principles that he and his team arrived at, he said something slowly and with great emphasis:

We really sweated the semantics.

The principles are important. They are directly tied to and defined to support the purpose of testing for his company. They are the foundation for all decisions that will be made about testing in the company. As you might expect given this, he was careful to also define what he means by a principle. For the record, this is it:

Principles are heuristics and shared values that guide our thinking about how to test and organize our testing.

I enjoyed Michael Bolton's talk, No More Exploratory Testing, as a story about the evolution of the semantics of some terms in our field (terms like checking, testing, ad hoc testing, exploratory testing) and how this evolution is intimately tied up with other factors such as changing context, new thinking, the recognition that the terms don't suit their intended purpose or are inconsistent with the use to which they are being put.

Bolton is big enough to note times at which he has helped (in retrospect) to make things worse (although in a well-intentioned quest to make things better) for instance by supporting the term 'sapient testing' which was widely misinterpreted to oppose 'non-sapient' or 'stupid' testing. And he arrives at an interesting conclusion: defining the terminology he wants to use in the way he wants to use it within a Rapid Software Testing namespace.

These two talks recognise a problem that Humpty Dumpty saw a long time ago: words can mean whatever you want them to mean. They both resolve the problem by (a) being careful to define the terms that matter to them as well as they can given their current understanding and context and (b) making a safe place to use that terminology in that way.

This approach is reasonable, sensible and practical and I've enjoyed mulling it over since. Here's a few thoughts:

Neither speaker refuses the right of others to use other terminology or the same terminology in different ways. Indeed, I perceive that both are prepared to make efforts to understand the terminology of others, even when they find strong reasons to object to it or the motivation for it. Evidence for this was seen in their questions at the session Stuart Reid and Anne Mette Hass lead on ISO 29119 at the conference.

There are risks to (being seen to be) setting up a walled garden. For example, that insiders will feel smug and become less inquisitive about the outside or that others will feel excluded, will ignore or reject it in its entirety, will begin some other process designed to be different for the sake of being different.

Neither speaker claims, as I see it, that their terminologies are correct, complete, static. I imagine they'd be happy to describe them as something like working definitions - the best they have given the context, experience, evidence and so on.

You might think that this stuff is theoretical nonsense; intellectual chin-stroking; deckchairs on the Titanic; fiddling while Rome burns. You might just want to get on and test. And that's your prerogative - and sometimes it's also the right thing to do - but I find that meaning matters massively and dealing with that is one of the hardest problems in testing because it is present to some extent in every single interaction you have with any person via any medium.

And, for me, that includes myself and my own mind.

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

Not Strictly for the Birds

One of my chores takes me outside early in the morning and, if I time it right, I get to hear a charming chorus of birdsong from the trees in the gardens down our road, a relaxing layered soundscape of tuneful calls, chatter, and chirrupping. Interestingly, although I can tell from the number and variety of trills that there must be a large number of birds around, they are tricky to spot. I have found that by staring loosely at something, such as the silhouette of a tree's crown against the slowly brightening sky, I see more birds out of the corner of my eye than if I scan to look for them. The reason seems to be that my peripheral vision picks up movement against the wider background that direct inspection can miss. An optometrist I am not, but I do find myself staring at data a great deal, seeking relationships, patterns, or gaps. I idly wondered whether, if I filled my visual field with data, I might be able to exploit my peripheral vision in that quest. I have a wide monito

Postman Curlections

My team has been building a new service over the last few months. Until recently all the data it needs has been ingested at startup and our focus has been on the logic that processes the data, architecture, and infrastructure. This week we introduced a couple of new endpoints that enable the creation (through an HTTP POST) and update (PUT) of the fundamental data type (we call it a definition ) that the service operates on. I picked up the task of smoke testing the first implementations. I started out by asking the system under test to show me what it can do by using Postman to submit requests and inspecting the results. It was the kinds of things you'd imagine, including: submit some definitions (of various structure, size, intent, name, identifiers, etc) resubmit the same definitions (identical, sharing keys, with variations, etc) retrieve the submitted definitions (using whatever endpoints exist to show some view of them) compare definitions I submitted fro

Vanilla Flavour Testing

I have been pairing with a new developer colleague recently. In our last session he asked me "is this normal testing?" saying that he'd never seen anything like it anywhere else that he'd worked. We finished the task we were on and then chatted about his question for a few minutes. This is a short summary of what I said. I would describe myself as context-driven . I don't take the same approach to testing every time, except in a meta way. I try to understand the important questions, who they are important to, and what the constraints on the work are. With that knowledge I look for productive, pragmatic, ways to explore whatever we're looking at to uncover valuable information or find a way to move on. I write test notes as I work in a format that I have found to be useful to me, colleagues, and stakeholders. For me, the notes should clearly state the mission and give a tl;dr summary of the findings and I like them to be public while I'm working not just w

Make, Fix, and Test

A few weeks ago, in A Good Tester is All Over the Place , Joep Schuurkes described a model of testing work based on three axes: do testing yourself or support testing by others be embedded in a team or be part of a separate team do your job or improve the system It resonated with me and the other testers I shared it with at work, and it resurfaced in my mind while I was reflecting on some of the tasks I've picked up recently and what they have involved, at least in the way I've chosen to address them. Here's three examples: Documentation Generation We have an internal tool that generates documentation in Confluence by extracting and combining images and text from a handful of sources. Although useful, it ran very slowly or not at all so one of the developers performed major surgery on it. Up to that point, I had never taken much interest in the tool and I could have safely ignored this piece of work too because it would have been tested by

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 team
