Quality is Value-Value to Somebody

A couple of years ago, in It's a Mandate, I described mandated science: science carried out with the express purpose of informing public policy. There can be tension in such science because it is being directed to find results which can speak to specific policy questions while still being expected to conform to the norms of scientific investigation. Further, such work is often misinterpreted, or its results reframed, to serve the needs of the policy maker.

Last night I was watching a lecture by Harry Collins in which he talks about the relationship between science and democracy and policy. The slide below shows how the values of science and democracy overlap (evidence-based, preference for reproducible results, clarity and others) but how science's results are wrapped by democracy's interests and perspectives and politics to create policies.

I spent some time thinking about how these views can serve as analogies for testing as a service to stakeholders.

But Collins says more that's relevant to that relationship in the lecture - much of it from his book Are We All Scientific Experts Now? In particular he argues that non-scientists' opinions on scientific matters should not generally be taken as seriously as those of scientists, those people who have dedicated their lives to the quest for deep understanding in an area.

He stratifies the non-scientific populus, though, making room for classes of expertise that are hard-earned - he terms them interactional expertise and experience-based expertise - that non-scientists can achieve and which make conversation with scientists, and even meaningful contribution to scientific debate, possible.

I find this a useful layer on the tester-stakeholder picture. Sure, most of our stakeholders might not know as much as we (think we) do about testing, about the craft and techniques of testing. But that doesn't mean that there aren't those who can talk to us knowledgeably about it. This kind of expertise might be from, say, reading (interactional) or perhaps from past testing practice or knowledge of the domain in which testing is taking place (experience-based) and I like to think that I am, and that we should be, open to it being valuable to us and whatever testing effort we're engaged in.

Can Code, Can't Code, Is Useful

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-- "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

Testing (AI) is Testing

Last November I gave a talk, Random Exploration of a Chatbot API , at the BCS Testing, Diversity, AI Conference . It was a nice surprise afterwards to be offered a book from their catalogue and I chose Artificial Intelligence and Software Testing by Rex Black, James Davenport, Joanna Olszewska, Jeremias Rößler, Adam Leon Smith, and Jonathon Wright. This week, on a couple of train journeys around East Anglia, I read it and made sketchnotes. As someone not deeply into this field, but who has been experimenting with AI as a testing tool at work, I found the landscape view provided by the book interesting, particularly the lists: of challenges in testing AI, of approaches to testing AI, and of quality aspects to consider when evaluating AI. Despite the hype around the area right now there's much that any competent tester will be familiar with, and skills that translate directly. Where there's likely to be novelty is in the technology, and the technical domain, and the effect of

Am I Wrong?

I happened across Exploratory Testing: Why Is It Not Ideal for Agile Projects? by Vitaly Prus this week and I was triggered. But why? I took a few minutes to think that through. Partly, I guess, I feel directly challenged. I work on an agile project (by the definition in the article) and I would say that I use exclusively exploratory testing. Naturally, I like to think I'm doing a good job. Am I wrong? After calming down, and re-reading the article a couple of times, I don't think so. 😸 From the start, even the title makes me tense. The ideal solution is a perfect solution, the best solution. My context-driven instincts are reluctant to accept the premise, and I wonder what the author thinks is an ideal solution for an agile project, or any project. I notice also that I slid so easily from "an approach is not ideal" into "I am not doing a good job" and, in retrospect, that makes me smile. It doesn't do any harm to be reminded that your cognitive bias

Play to Play

I'm reading Rick Rubin's The Creative Act: A Way of Being . It's spiritual without being religious, simultaneously vague and specific, and unerring positive about the power and ubiquity of creativity. We artists — and we are all artists he says — can boost our creativity by being open and welcoming to knowledge and experiences and layering them with past knowledge and experiences to create new knowledge and experiences. If that sounds a little New Age to you, well it does to me too, yet also fits with how I think about how I work. This is in part due to that vagueness, in part due to the human tendency to pattern-match, and in part because it's true. I'm only about a quarter of the way through the book but already I am making connections to things that I think and that I have thought in the past. For example, in some ways it resembles essay-format Oblique Strategy cards and I wrote about the potential value of them to testers 12 years ago. This week I found the f

Rage Against the Machinery

I often review and collaborate on unit tests at work. One of the patterns I see a lot is this: there are a handful of tests, each about a page long the tests share a lot of functionality, copy-pasted the test data is a complex object, created inside the test the test data varies little from test to test. In Kotlin-ish pseudocode, each unit test might look something like this: @Test fun `test input against response for endpoint` () { setupMocks() setupTestContext() ... val input = Object(a, OtherObject(b, c), AnotherObject(d)) ... val response = someHttpCall(endPoint, method, headers, createBodyFromInput(input) ) ... val expected = Object(w, OtherObject(x, y), AnotherObject (z)) val output = Object(process(response.getField()), otherProcess(response.getOtherField()), response.getLastField()) assertEquals(expected, output) } ... While these tests are generally functional, and I rarely have reason to doubt that they

README

This week at work my team attended a Myers Briggs Type Indicator workshop. Beforehand we each completed a questionnaire which assigned us a personality type based on our position on five behavioural preference axes. For what it's worth, this time I was labelled INFJ-A and roughly at the mid-point on every axis. I am sceptical about the value of such labels . In my less charitable moments, I imagine that the MBTI exercise gives us each a box and, later when work shows up, we try to force the work into the box regardless of any compatiblity in size and shape. On the other hand, I am not sceptical about the value of having conversations with those I work with about how we each like to work or, if you prefer it, what shape our boxes are, how much they flex, and how eager we are to chop problems up so that they fit into our boxes. Wondering how to stretch the workshop's conversational value into something ongoing I decided to write a README for me and
