The Tester Connector

Connections. We spend our time searching for them, stumbling across them, postulating them, making them, questioning them, confirming them, creating them and breaking them. They might be between products, between bits of your product, between people, between the ideas different people have, between different ideas that you have, between what you've seen, what you're seeing and what you might hope or fear seeing next.

finding associations (or the lack of them) between the system under test and something else.
connecting the product's behaviour with some notion of what it's supposed to do - or not do.
building links between components in your mental model of how an application works.
relating a new bug to previous ones.
identifying areas of consensus or disagreement, bringing concepts and people together.

I think therefore I am is fine and dandy, M. Descartes, but for testers I wonder if this would be better: If I am not connecting, I am not.

I am. Or, at least, I was when I first thought it and asked myself whether it had any validity. And I guess I'm hoping to connect with you, right now. So let's say I am. Here's what happened...

While I was writing No F in Spec a couple of weeks ago I was also finishing up a round of annual appraisals and had recently attended a UK Test Management Forum meeting where I'd been introduced to the term futurespective. It occurred to me that there's a link between specification, introspection (which I'd been praising and encouraging in appraisal) and futurespective.

Coincidence to have them all drop on me at once but it piqued my interest and so I looked them up to see if they shared a common root. It turns that they're from two distinct Latin words (to view, to be specific) so there's no etymological connection, although it doesn't matter: it spurred an interesting thought, one that I'd never brought out explicitly before; specification as a view of (some aspects of) intended behaviour.

But the process of looking for the connection triggered another thought on the nature of connections themselves. I stored it away for later and wasn't actively pursuing it when the phase only connect floated into my mind. A phrase that I'd heard but never understood the context of. So I looked it up. Interesting. Later the same day I was browsing Twitter and this tweet from @kinofrost leapt out of my timeline:

Listening to @GaryDelaney on @ComComPod. Loads of information on cross-role and cross-purpose heuristics, totally fascinating.

Cross-role, cross-purpose? Connections! Delaney is a comedian whose stock in trade is the one-liner and in the podcast the tweet refers to he deconstructs one, explaining how he starts with a punchline and then looks for related ideas that can be used to build to it, enabling it to be seen only at the reveal. The humour comes from multiple connections being possible at the same time and the listener being forced to switch from one to the other. (In passing he also makes his own connections between the delivery style of comedians and evangelical preachers, hype men, Martin Luther King and Hitler.)

And in turn that reminded me of a forum post I made at the Software Testing Club a couple of years ago where I was asking what testers just do naturally that they think is useful to them as a testing tool. For me, punning is an innate habit and feels intuitively very similar to what Delaney describes: take some concept and run through things that have some kind of relationship to it looking for an ambiguity to exploit. James Christie noted that he, as a matter of course, "mentally check[s] relationships. Mistakes in newspapers leap out at me, like someone being born in 1940, then a few paragraphs later entering college at the age of 18 in 1957."

We both picked out habits that build relationships. I wondered whether the vogue for mind maps in testing is a reflection of this more generally? I began to see an analogy between a network of connections and an exploratory search space - which branch to follow? Why? When? I started to think about the value of being exposed to a wide range of inputs in order to enable more connections. I thought about the need to filter connections out to avoid noise; about how repeated bad connections - biases? - can be identified and cast aside. I speculated about testing heuristics and mnemonics as devices that suggest ways in which connections have been made previously in software testing and which could be useful again. And I thought more about how lateral thinking can be valuable in this respect too; with puns there's no reason for a logical relationship between two concepts to exist as long as the result is a useful one.

And so I started writing it up, to get it straight in my head - which is how it works best for me - and, in the course of doing that I realised I'm connecting with my earlier train of thought but wondering something more general this time: maybe testing isn't helped by the skill of making connections but instead maybe testing is making connections?

Then as I concluded that round of writing I found I'd connected back to the word archaeology I was doing at the beginning, with a new word I learned looking up my Latin. I'd ended up with an F in conspectus.

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
