Why Not a Testing Standard?


The Cambridge Tester Meetup last night was a discussion on testing standards. Not on the specific question of ISO 29119 (for which see Huib Schoots' excellent resource) but more generally on the possibility of there being a standard at all. It was structured along the lines of Lean Coffee with thoughts and questions being thrown down on post-its and then grouped together for brief discussion.

I've recorded the content of the stickies here with just a little post-hoc editing to remove some duplication or occasionally disambiguate. The titles were just handles to attach stickies to once we had a few in an area and I haven't tried to rationalise them or rearrange the content.

Enhance/Inhibit Testing

  • Testing is a creative process so can't be standardised.
  • Testing doesn't fit into a standard format, so how can there be a standard for it? (Do we mean "good testing" whatever that is?)
  • New tools, technology might not fit into a standard.
  • Standardisation destroys great design ideas by encouraging/forcing overly broad application.
  • Can a general standard really fit specific project constraints?
  • Each tester is different.
  • A standard limits new thinking.
  • Could a standard be simply "Do the best you can in the time you have"?

Who Benefits?

  • Who do certifications serve anyway? What do they want from them?
  • As litigation becomes more prevalent who is protected by a standard? Customers, producers, users?
  • With a standard, companies can be "trusted" (QA-approved sticker).
  • People outside of test are usually very opinionated. Do standards help or hinder?
  • End users care because of the possible added costs.
  • A testing standard would provide false reassurance for companies.

Communication

  • How does an agile team fit in the standard?
  • Too much documentation? Standards may cause the need for more documentation to show compliance.
  • Standard language for communicating test ideas.
  • Divide the testing community - good or bad?
  • Respond to feedback and criticism.

How Much? or Alternatives

  • Do we need an alternative at all?
  • Where are the standards for science, consultancy, product management, development?
  • Use as much or as little of a standards as needed?
  • Could a standard be subjective?
  • Standards for products, or the process of creating products?
  • What else do we need or want instead?
  • Could a standard cover the minimum at least?
  • A standard should be flexible to adapt to project constraints.

Useful Subsets

  • Can a single standard fit different products? (Angry Birds vs nuclear reactor).
  • Uniformisation of some testing (bring up the baseline).
  • There are already some government standards.
  • Infinite space of testing. Can a standard capture that?
  • Can some aspects of testing be covered by standards? If so, which?

Can't we Just Explore?

  • Scientists do. Why can't we? (But what about mandated science?)
  • Approaches in methodologies used set out in a common understood format could help consistency.

Fear of Being Assessed?

  • Are testers just scared of being evaluated or taking responsibility?
  • I'm too shy.
  • Could it open up law suites, blame and other consequences?
  • Should you insure yourself or your company against any not conforming to the standard?
  • Anything unstructured used as an addition to, rather than part of, the primary approach. Stops people hiding?

Show Me the Money?

  • What is the motivation of those seeking to create certification? (Rent-seekers?) 
  • It's just to make money for ISO companies.
  • Adds organisation to a "messy" activity.

Certify Testers Not Testing

  • Can you differentiate certifications for testers from certifications for pieces of work? (c.f. Kaner
  • Can you say "product tester by a tester certified XYZ"?
  • How would recruitment distinguish between testers and checkers?
  • An independent body to audit the testing/tester on real project work? (Who audits the auditor?)
  • Qualification vs certification vs standardisation.

Standards in Other Industries

  • Learn more about standards in other industries and how they dealt with their first standard.
  • Standards in e.g. car safety are on the result of the work not the methodology? 
  • Universities and schools start teaching testing. Should they teach about the standards?
  • Standards to help produce evidence of testing not just test plans, which are usually fiction.
  • "Informed" standards (courses, talks etc), "in-house" standards?

Misc

  • Are objections to certification objections to theoretical risks but in practice it's possible to have something good enough?
  • Would companies without testers need a testing standard?
  • Development standards to be closely linked to testing standards.
  • Easy to find jobs abroad (if there were standardisation).
  • A standard would be good as a product.
  • Would a standard really impact our day-to-day job?
  • Is the standard simply a reason to justify testing?
  • Is the idea of a standard predicated on an outdated idea of testing?
As you can see there was no shortage of ground to cover but, with only a couple of hours, plenty was necessarily shallow or not dug into at all.

To pull out a handful of  points that I found particularly interesting: we were not shy about asking questions and we were prepared to aim them at ourselves; we bumped into the distinction between certifying product, tester and testing multiple times; we didn't really explore what we meant by standards, certification and qualification and what the differences between them might be; while the discussion was entered into with an open mind (which was the remit) there were sometimes implicit assumptions about what a standard must entail (inflexibility; lots of documentation etc) which were mostly negative and where positives were proposed they tended to be viewed more as possibilities.

P.S. There's a few photos.

The Ideal Test Plan

A colleague pinged me the other day, asking about an "ideal test plan" and wondering whether I could suggest something. Not without a bit more information, I said. OK, they said. Who needs the plan, for what purpose? I asked. Their response: it's for internal use, to improve documentation, and provide a standard structure. We work in a medical context and have strict compliance requirements, so I wondered aloud whether the plan is needed for audit, or to show to customers? It's not, they replied, it's just for the team. Smiling now, I stopped asking questions and delivered the good news that I had what they were looking for. Yes? they asked, in anticipation. Naturally I paused for dramatic effect and to enhance the appearance of deep wisdom, before saying: the ideal plan is one that works for you. Which is great and all that, but not heavy on practical advice. --00-- I am currently running a project at the Association for Software Testing and there is a plan for

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

69.3%, OK?

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 ,  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-- "What percentage of our test cases are automated?" There's a lot wrapped up in that question, particularly when it's a metric for monitoring the state of testing. It's not the first time I've been asked either. In my

Why Do They Test Software?

My friend Rachel Kibler asked me the other day "do you have a blog post about why we test software?" and I was surprised to find that, despite having touched on the topic many times, I haven't. So then I thought I'd write one. And then I thought it might be fun to crowdsource so I asked in the Association for Software Testing member's Slack, on LinkedIn , and on Twitter for reasons, one sentence each. And it was fun!  Here are the varied answers, a couple lightly edited, with thanks to everyone who contributed. Edit: I did a bit of analysis of the responses in Reasons to be Cheerful, Part 2 . --00-- Software is complicated, and the people that use it are even worse. — Andy Hird Because there is what software does, what people say it does, and what other people want it to do, and those are often not the same. — Andy Hird Because someone asked/told us to — Lee Hawkins To learn, and identify risks — Louise Perold sometimes: reducing the risk of harming people —

My Favourite Tool

Last week I did a presentation to a software testing course at EC Utbildning in Sweden titled Exploring with Automation where I demoed ways in which I use software tools to help me to test. Following up later, one of the students asked whether I had a favourite tool. A favourite tool? Wow, so simple but sooo deep!  Asking for a favourite tool could make a great interview question, to understand the breadth and depth of a candidate's knowledge about tools, how they think about an apparently basic request with deep complexity beneath (favourite for what task, on what basis, in what contexts, over what timescale?  what is a tool anyway?) and how they formulate a response to take all of that into account. I could truthfully but unhelpfully answer this question with a curt Yes or No. Or I could try and give something more nuanced. I went for the latter. At an extremely meta level I would echo Jerry Weinberg in Perfect Software : The number one te

Trying to be CEWT

I attend, enjoy, hopefully contribute to, and get a lot from, the local tester meetups and Lean Coffee  in Cambridge. But I'd had the thought kicking around for a long time that I'd like to try a peer workshop inspired by MEWT , DEWT , LEWT and the like. I finally asked a few others, including the local meetup organisers, and got mostly positive noises, so I decided to give it a go. I wrote a short statement to frame the idea, based on LEWT's: CEWT ( Cambirdge Exploratory Workshop on Testing ) is an exploratory peer workshop. We take the view that discussions are more interesting than lectures. We enjoy diverse ideas, and limit some activities in order to work with more ideas. and proposed a mission for an initial attempt to validate it locally on a small scale. Other local testers helped to refine the details in usual the testing ways - you know: criticism, questions, thought experiments, challenges, comparisons, mockery and the rest - and a list of potential at

Fail Here or Fail There

The First Law of Systems-Survival, according to John Gall, is this: A SYSTEM THAT IGNORES FEEDBACK HAS ALREADY BEGUN THE PROCESS OF TERMINAL INSTABILITY Laws are all-caps in Systemantics . Not just laws, but also theorems, axioms, and corollaries. There are many of them so here's another (location 2393-2394): JUST CALLING IT “FEEDBACK” DOESN’T MEAN THAT IT HAS ACTUALLY FED BACK There was a point when I realised, as the capitalised aphorisms rolled by, that I was sinking into the warm and sweetly-scented comforting foamy bathwater of confirmatory bias. Seen, seen, seen! Tick, tick, tick! I took the opportunity to let myself know that I'd been caught in the act, and that I needed to get out of the tub and start to challenge the content.  Intervening at that moment was congruent: I was in a context where I would accept it and prepared to change because of it. Of course, I enjoyed the deep irony of nodding along with Gall when he talked about

Testing and Words

  The other day I got tagged on a Twitter thread started by Wicked Witch of the Test about people with a background in linguistics who’ve ended up in testing. That prompted me to think about the language concepts I've found valuable in my day job, then I started listing them, and then realised how many of them I've mentioned here over the years .   This post is one of an occasional series collecting some of those thoughts.  --00-- In The Complete Plain Words , Ernest Gowers notes, acidly, that: What appears to be a sloppy or meaningless use of words may well be a completely correct use of words to express sloppy or meaningless ideas. It surely sounds trite to say it but our choice of words can make a significant difference to how well our message is understood, and how we are judged. We choose from amongst those words we know, our lexicons . The more my lexicon agrees with yours, the greater our chance of us achieving a shared understanding when we converse. But lexic

Use the Force Multiplier

On Fridays I pair with doctors from Ada 's medical quality team. It's a fun and productive collaboration where I gain deeper insight into the way that diagnostic information is encoded in our product and they get to see a testing perspective unhindered by domain knowledge. We meet at the same time each week and decide late on our focus, choosing something that one of us is working on that's in a state where it can be shared. This week we picked up a task that I'd been hoping to get to for a while: exploring an API which takes a list of symptoms and returns a list of potential medical conditions that are consistent with those symptoms.  I was interested to know whether I could find small input differences that led to large output differences. Without domain knowledge, though, I wasn't really sure what "small" and "large" might mean. I prepared an input payload and wrote a simple shell script which did the following: make a
