Can Code, Can't Code, Is Useful

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.

"If testers can’t code, they’re of no use to us"

My first reaction is to wonder what you expect from your testers. I am immediately interested in your working context and the way that you delineate roles and responsibilities within it.

As presented, the statement seems more absolutist than I am comfortable with. I tried to check my prejudices at the door by looking for situations in which it might be uttered without (excessive) controversy. Maybe these?

to HR, to filter applicants for an oversubscribed testing position
in a consultancy, to satisfy a non-negotiable client demand
on a project where the system under test only has a programmatic interface

Close behind my initial curiosity comes a sense of foreboding that this might be one of those conversations in which the potential value of a specialist tester is not appreciated.

For today, let's assume my scepticism is unwarranted and that you'll humour me for a few minutes by answering my questions because you are interested in having your assumptions challenged and open to the possibility that you might change your mind.

So, without wanting to get heavy about semantics, it was interesting that you phrased your statement with two negatives. To help me interpret it, I tried to sketch some possible scenarios. You can see them at the top.

Some testers who can code are useful but no-one else is
All testers who can code are useful but no-one else is
Some testers who can code are useful along with others who are not testers
All testers who can code are useful, along with others who are not testers

I wonder if any of those capture your thinking more precisely?

While we're on this track, your statements appear very binary. A person can either code or not? A person is either useful or not? Is there no room for nuance at all in your situation?

Could it be that you're thinking about coding and utility in specific and constrained ways? For example, could you imagine a scenario in which a tester had some knowledge of coding and brought value outside the places you'd traditionally expect?

What does useful mean to you? What does a useful tester mean to you? If coding is so important, what additional value do you get from a tester who can code over anyone else who can code? If there's nothing, why are you looking for a tester? If there's something, why couldn't a tester do that, and be supported by someone else who can code?

And coding is a broad church. Someone who's fluent in a specialist DSL based on Prolog for an AI application might be awful at C on an embedded micro-controller. Is it enough that the tester can hack together a temporary test rig out of Python and bash, or do you need someone who can architect and build a company-wide, end-to-end, full-stack, framework?

I feel like we could talk for hours. It's so refreshing to have this kind of conversation with an engaged stakeholder who cares to take the time to explore their position with the aim of getting a better understanding and outcome.

And that's one of the things a skilled tester can help to do ... without writing a single line of code.

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
