Pizza Chants

So my wife caught me giggling to myself in the kitchen. Why? I'd just seen a really corny pun on peace and peas. It wasn't the "classic" above but it was the same kind of thing. In fact, it wasn't the joke itself that had caused me to crack my face at all, but the thoughts spurred from the desire to make a better one from the same phonetic premise.

The first thing I come up with is:

Give Pisa chance

This slight variation on the well-known punchline is a plausible sentence but to make it work as a joke I need a context that can produce it. I'm working backwards from a result to look for some setup in which it is coherent:

Did you know that casinos are illegal in some parts of Italy? Apparently a bunch of gamblers held a candlelit protest overnight.

They were singing "All we are saying is give Pisa chance."

This is also a testing pattern. When you're looking at responses from a system, a useful approach to finding potential issues can be:

I've got X.
By changing X a little I can get Y.
Y is plausible.
Y would be bad.
What context could give me Y?

The comedian Milton Jones has a beautiful gag which is a series of one-liners with the punch line "Your house stinks" spread out in his set:

Anyone here own a cat?
Any students in tonight?

So, you know what the punch line is going to be, what context might give a laugh here? He goes for:

Is anyone in the audience an aromatherapist?

Which is not only funny, but also a (comedy) rule of three.

Meanwhile, back in the kitchen, I am busy applying another pattern - I think of it loosely as the Spooner - where you can look for the funny by permuting some aspect(s) of multiple elements. For example switching the initial sounds of peace and chance:

Give cheeser pants
Give cheetahs pants
Give cheaters pants
Give cheetah's pants

Small beer, perhaps. No obviously gut-busting laughs here, I'll grant you. But you could imagine contexts in which you could set these some of these up as jokes, although I will say that if you search for "cheetahs pants" as I did, looking for clues to such a context, you get a lot of photos of leopard skin leggings. Which - fashion naif that I am - violated both my expectations and my eyes.

But that's testing too: generate ideas and choosing to use them or not (at the moment). Sometimes rote generation by some formula like this is productive and sometimes not so much. As it happens, I decide to try to stretch this line further (like some of those leggings) and end up with:

Give peaches pants

Which I found an amusing idea (this was the point my wife came to ask what had happened to her coffee) although probably a step too far in terms of plausibility... but I later found this picture:

To relate this back to testing with a specific example: imagine you have some functionality that accepts a couple of arguments. You might ask yourself questions like these:

what happens if the arguments are given in the wrong position?
does the structure, naming, usage etc of this functionality make it likely that users will mix up the arguments?
how would someone spot that they had made this kind of mistake?

I find an interesting overlap in techniques and skills I use for joking and testing and I use one to keep in trim for the other. I'll be talking about it at the Cambridge Tester Meetup and the UKTMF next month and then EuroSTAR in November.

The last possibility: "how would someone spot that they had made this kind of mistake?" is academic and would not add quality in my opinion. But I am brute force kind of guy and hence I would use that in two ways, to randomize the input data ordering, or to systematically validate failure for all combinations except for the valid combinations. Interestingly enough swapping arguments around unpredictably is bound to open up cases where the parameter values may randomly have the same semantic value and hence once again automation may draw false positives out. Lets use an example in a language-agnostic or type-insensitive way:
test1 = "hello", "conrad", 1 , FALSE
test2 = "conrad", "hello", FALSE, 1
Would both pass the case for the function prototype:
Greeting ([string]anouncement , [string]recipient, [integer]repeatTimes, [bool]broadcastTweet)
But would produce a passing result even though the parameters are randomly ill placed. I'm no fan of fuzzing, but I'm warming to it as a away of understanding ways of breaking APIs in a useful fashion by first feeding them data that "kinda" fits a mould. A bit like the rhyme:
Give peas a chance = verb+noun+verb and/or optional conjunction ?

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 ...
