Cambridge Lean Coffee


This month's Lean Coffee was hosted by DisplayLink. Here's some brief, aggregated comments and questions on topics covered by the group I was in.

Are testers doing less and less testing?

  • The questioner is finding that testers today are doing more "other" activities, than he was in his early days of testing.
  • Where's the right balance between testing and other stuff?
  • What's your definition of testing?
  • I think that exploring ideas is testing.
  • I fall into a "support" role for the team; I'm the "glue" in the team, often.
  • I focus on the big picture.
  • I am thinking about what needs to be ready for the next phase, and preparing it.
  • I am thinking about information gathering and communication to stakeholders.
  • Is there a contradiction: testers are a scarce resource, but they're the ones doing "non-core" activities.
  • Perhaps it's not a contradiction? Perhaps testers are making themselves a scarce resource by doing that other stuff?
  • Doing other stuff might be OK, but you want others to take a share of it.
  • Doing some other stuff is OK, but perhaps not all of the housekeeping.
  • I want to focus on testing, not housekeeping.
  • Seniority is one of the reasons you end up doing less testing.
  • Less testing, or perhaps you have less engagement with the product?
  • I am doing more coaching of developers these days, and balancing that with exploratory testing.
  • In the absence of an expert, people expect the tester to take a task on.
  • Are developers more hesitant to take on other tasks, generally?
  • Or is the developer role just so much better defined that it's not asked of them?
  • Are you sure developers aren't doing non-development work? What about DevOps?
  • The tester contract at my work includes that testers will support others.
  • Is there a problem here? Perhaps the role is just changing to fit business needs?

How do you differentiate between a test plan and a test strategy?

  • What are they? What are the differences between them?
  • Why does it matter?
  • Plan: more detailed, acceptance criteria, specific cases, areas.
  • Strategy: high-level, test approach, useful for sharing with non-testers.
  • ... but most people don't care about this detail.
  • Do any of the participants here have required documents called Test Plan and Test Strategy on products? (Some did.)
  • Most projects have a place for strategy and tactics.
  • ... and the project context affects the division of effort that should be put into them.
  • ... and ideally the relationship between them is one of iteration.
  • Ideally artefacts are not producted once up-front and then never inspected again.
  • You might want some kind of artefact to get customer sign-off.
  • Your customer might want to see some kind of artefact at the end.
  • .... but isn't that a report of what was done, not what was planned (and probably not done)?

Can testing be beautiful?

  • When it returns stakeholder value efficiently.
  • When you've spent time testing something really well and you get no issues in production.
  • When you identify issues that no-one else would find.
  • When others think "I would never have found that!"
  • When the value added is apparent.
  • When you can demonstrate the thought process.
  • When you make other people aware of a bigger picture.
  • When you uncover an implicit customer requirement and make it explicit.
  • When you keep a lid on scope, and help to deliver value because of it.
  • OK, when is testing ugly?
  • When you miss issues and there's a bad knock-on effect.
  • When you have reams of test cases. In Excel.
  • When testing is disorganised, lacking in direction, lacking in focus, unprofessional.
  • Is beauty in the actions or the result?
  • Is beauty in the eye of the artist, or the audience?
  • Or both?

What is a tester's role in a continuous delivery pipeline?

  • When the whole pipeline is automated, where do testers fit?
  • There's an evolution in the tester skillset; the context is changing.
  • Shift left?
  • Shift in all directions!
  • Testing around and outside the pipeline.
  • Asking where the risks are.
  • Analysing production metrics.
  • Are we regressing? Isn't CD a kind of waterfall?
  • Less a line from left to right, and more a cascade flowing through gates?
  • ... perhaps, but the size of the increments is significant.

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 . 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.

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...

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...

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...

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...

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 ...
