Listens Learned in Software Testing

I'm enjoying the way the Test team book club at Linguamatics has been using our reading material as a jumping-off point for discussion about our experiences, about testing theory, and about other writing. This week's book was a classic, Lessons Learned in Software Testing, and we set ourselves the goal of each finding three lessons from the book that we found interesting for some reason, and making up one lesson of our own to share.

Although Lessons Learned was the first book I bought when I became a tester, in recent times I have been more consciously influenced by Jerry Weinberg. So I was interested to see how my opinions compare to the hard-won suggestions of Kaner, Bach and Petttichord.

For this exercise I chose to focus on Chapter 9, Managing the Testing Group. There are 35 lessons here and, to the extent that it's possible to say with accuracy given the multifaceted recommendations in many of them, I reckon there's probably only a handful that I don't practice to some extent.

One example: When recruiting, ask for work samples (Lesson 243). This advice is not about materials produced during the interview process. It is specifically about bug reports, code, white papers and so on from previous employments or open source projects. I can't think of an occasion when I've asked for that kind of thing from a tester.

Of the 30 or so lessons that I do recognise in my practices, here's three that speak to me particularly today: Help new testers succeed (Lesson 220), Evaluate your staff as executives (Lesson 213), The morale of your staff is an important asset (Lesson 226).

Why these? Well, on another day it might be three others - that's what I've found with this book over the years - but in the last 12 months or so our team has grown by 50% and we've introduced line management structure. This triplet speak to each of those changes and the team as a whole, as we work through them.

When bringing new people into our team we have evolved an induction process which has them pair with everyone else on the team at least a couple of times, provides a nominated "first point of contact", a checklist of stuff to cover in each of the first days, weeks and months, a bunch of introductions to the Test team and company (from within the team) and to other parts of the company (from friendly folk in other groups). We also have the new person present to the team informally about themselves and their testing, to help us to get to know them, develop some empathy for them, to give them some confidence about talking in front of the established staff. Part of the induction process is to provide feedback on the induction process (this is not Fight Club!) which we use to tune the next round.

Until this year, I have conducted all annual reviews for all of the testers in my team. This affords me the luxury of not having to have externalised the way in which I do it. That's not to say that I haven't thought about it (I have, believe me, a lot) or that I haven't evolved (again, I have) but more that I haven't felt the need to formally document it. Now that there are other line managers in the team I have begun that process by trying to write it down (almost always a valuable exercise for me) and explaining it verbally (likewise; particularly when doing it to a bunch of intelligent, questioning testers).

How to assess the performance and development needs of your team (fairly) is tricky. The notion of executive in Lesson 213 is from Drucker - "someone who manages the value of her own time and affects the ability of the organisation to perform" as Lesson 211 puts it - and essentially cautions against simple metrics for performance in favour of a wide spread of assessments, at least some of which are qualitative, that happen regularly and frequently. It recommends paying attention to your staff, but contrasts this with micromanagement.

Past experience tells me that there is almost never consensus on a course of action within my teams and I rarely get complete agreement on the value of an outcome either. However, it's important to me to be as inclusive and open and transparent as possible about what I'm doing, in part because that's my philosophical standpoint but also because I think that it contributes to team morale, and that is crucial to me (Lesson 226) because I think a happy team is in a position to do their best work.

When planning and going through the kind of growth and restructuring that our team has in the last 12 months, morale was one of my major concerns - of the new hires, of the existing team members, and also of myself. It's my intuition that important aspects of building and maintaining morale in this kind of situation include providing access to information, opportunity to contribute, and understanding of the motivation.

I didn't want anyone to feel that changes were just dropped on them, that they weren't aware that changes were coming, that they had no agency, that they hadn't had chance to ask questions or express their preferences or suggestions, and that I hadn't tried to explain what options were being considered and why I made the particular changes that I did, and what my concerns about it are, and that my full support is available to anyone who wants or needs it.

The lesson of my own that I chose to present is one I've come back to numerous times over the years:

If you can, listen first.

Listening here is really a proxy for the intake of information through any channel, although listening itself is a particularly important skill in person-to-person interactions. Noticing the non-verbal cues that come along with those conversations is also important, and likewise remembering that the words as said are not necessarily the words as meant.

Since reading What Did You Say? I have become much more circumspect about offering feedback. Feedback is certainly part of the management role - any manager who is not willing to give it when requested is likely not supporting their staff to the fullest extent they could - but feeling that it's the manager's role to dispense feedback at (their own) will is something I've come to reject.

These days I try to practice congruent management and a substantial part of that is that it requires understanding - of the other person, the context and yourself. Getting data on the first two is important to aid understanding, and listening - really listening, not just not speaking - is a great data-gathering tactic. The Mom Test, which I read recently, makes essentially the same point over and over and over. And over.

Listening isn't always pleasant - I think, for example, of a 30-minute enumeration of things a colleague felt I hadn't done well - but I try to remember that the other person - if being honest - is expressing a legitimate perspective - theirs - and understanding it and where it comes from - for them - is likely to help me to understand the true meaning of the communication and help me to deal with it appropriately.

And that's a lesson in itself: managing is substantially about doing your best to deal with things appropriately.

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. Perhaps you'd like to join me? --00-- "Stop answering my questions with questions." Sure, I can do that. In return, please stop asking me questions so open to interpretation that any answ...

How do I Test AI?

Recently a few people have asked me how I test AI. I'm happy to share my experiences, but I frame the question more broadly, perhaps something like this: what kinds of things do I consider when testing systems with artificial intelligence components . I freestyled liberally the first time I answered but when the question came up again I thought I'd write a few bullets to help me remember key things. This post is the latest iteration of that list. Caveats: I'm not an expert; what you see below is a reminder of things to pick up on during conversations so it's quite minimal; it's also messy; it's absolutely not a guide or a set of best practices; each point should be applied in context; the categories are very rough; it's certainly not complete. Also note that I work with teams who really know what they're doing on the domain, tech, and medical safety fronts and some of the things listed here are things they'd typically do some or all of. Testing ...

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...

Notes on Testing Notes

Ben Dowen pinged me and others on Twitter last week , asking for "a nice concise resource to link to for a blog post - about taking good Testing notes." I didn't have one so I thought I'd write a few words on how I'm doing it at the moment for my work at Ada Health, alongside Ben. You may have read previously that I use a script to upload Markdown-based text files to Confluence . Here's the template that I start from: # Date + Title # Mission # Summary WIP! # Notes Then I fill out what I plan to do. The Mission can be as high or low level as I want it to be. Sometimes, if deeper context might be valuable I'll add a Background subsection to it. I don't fill in the Summary section until the end. It's a high-level overview of what I did, what I found, risks identified, value provided, and so on. Between the Mission and Summary I hope that a reader can see what I initially intended and what actually...

On Herding Cats

Last night I was at the Cambridge Tester meetup for a workshop on leadership. It was a two-parter with Drew Pontikis facilitating conversation about workplace scenarios followed by an AMA with a group of experienced managers. I can't come to work this week, my cat died. Drew opened by asking us what our first thoughts would be as managers on seeing that sentence. Naturally, sadness and sympathy, followed by a week ? for a cat ? and I only got a day for my gran! Then practicalities such as maybe there's company policy that covers that , and then the acknowledgement that it's contextual: perhaps this was a long-time emotional support animal . Having established that management decisions are a mixture of emotion, logic, and contingency Drew noted that most of us don't get training in management or leadership then split us into small groups and confronted us with three situations to talk through: Setting personal development goals for others. Dropping a clange...

Reasonable Doubt

In Your job is to deliver code you have proven to work Simon Willison writes: As software engineers we ... need to deliver code that works — and we need to include proof that it works as well. He is coming at this from the perspective of LLM-assisted coding, but most of what he says applies in general. I think this is a reasonable consise summary of his requirements for developers: Manual happy paths: get the system into an initial state, exercise the code, check that it has the desired effect on the state. Manual edge cases: no advice given, just a note that skill here is a sign of a senior engineer. Automated tests: should demonstrate the change like Manual happy paths but also fail if the change is reverted. He notes that, even though LLM tooling can write automated tests, it's humans who are accountable for the code and it's on us to "include evidence that it works as it should." Coincidentally, just the week before I read his post I told one of my...

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...

Why Test, Test What, Then How?

There was a time when testing was all about the mnemonics . Well, we had no AI back then so thinking about our human craft and how to share what we had learned using our human intelligence with other engaged humans for later recall in their human heads seemed important. But this post isn't about dumping on AI. It isn't about mnemonics either even if WTTWTH does look like something that'd fit well into that ancient world. No, this post is just a snappier version of what I said to my team this week when I was walking through some testing I'd done the day before. It was concerned with a change to a particular turn in the dialog system we're building where multiple variables are in play, some populated by an external call to an LLM service. I wanted to make the point that the bulk of the testing work was done in the research I did and the spreadsheet I made, not in the interaction with our product. That spreadsheet was the result of me looking in our service's cod...

Open Your Mind

Jerome Groopman, in How Doctors Think , reviews ways in which doctors can make poor choices, identifies potential causes, and suggests some practices, for both doctor and patient, that can help to prevent them. I find this interesting for a couple of reasons: first, I work in the health space, although not in a therapeutic area and, second, I like to reflect on my own thought processes. I'll take three broad themes from Groopman's analysis: the business of healthcare and how that impacts a physician's ability to practice; the doctor-patient relationship and how that impacts the experience of both sides; and the cognitive failings that impact a correct and timely diagnosis for any given patient. Naturally, these overlap. The book is written from the perspective of the notoriously commercialised American medical system and is around 20 years old, so doubtless some of the details are different outside of the US and have changed since pu...

Better Isolate Than Never

How do you test a product with distributed logic and non-deterministic components? Well, it depends on the product and when the question is asked. This post is one answer, for now. A service I work on exposes an API for internal and external clients and calls multiple other services. It orchestrates a reasonably complex journey for a user, with their inputs and the responses of the services determining each step. Our customers can configure the service to provide a variant of the standard journey for their users. This gives them choices on the available steps, the order of the steps, and, importantly, some of the logic for taking particular steps. This configuration lives in a different repository to the service, not owned by us, and it can be changed and deployed independently from the service. As you can imagine, we test our service in multiple ways at different granularities using the usual tooling, including unit tests fo...
