State of Testing 2016 – My view

Usually I don’t write many promotions for other’s contents on this blog as I try to keep it personal and focused on my personal views. Recently I was contacted on the International 2016 State of Testing report, and whether I would like to do a write-up about it. I asked whether it would be ok to post a personal view, so here it is.

On auditing, standards, and ISO 29119

Since I am publishing this on my personal blog, this is my personal view, the view of Markus Gärtner as an individual.

I think the first time I came across ISO 29119 discussion was during the Agile Testing Days 2010, and probably also during Stuart Reid’s keynote at EuroSTAR 2010. Remembering back that particular keynote, I think he was visibly nervous during his whole talk, eventually delivering nothing worth of a keynote. Yeah, I am still disappointed by that keynote four years later.

Recently ISO 29119 started to be heavily debated in one of the communities I am involved in. Since I think that others have expressed their thoughts on the matter more eloquently and deeper than I going to do, make sure to look further than my blog for a complete picture of the whole discussion. I am going to share my current state of thoughts here.

Principles of ATDD: Single Responsibility Principle

The other day, I sat down Kishen Simbhoedatpanday in order to talk about ATDD, and eventually an upcoming class on the implementation side of ATDD. We talked about maintainable tests, and how you could refactor tests to yield better tests. Gojko wrote about the anatomy of a good acceptance test a while back, and I think we can be more explicit here. Then it struck me. The Single Responsibility Principle also applies to your automated examples – and why that’s the case. You just need to think on a conceptual level about it. Mixing business domain concerns with application concerns in your examples – and sometimes even with driver concerns (think Selenium) – is a terrible thing to do.

Let’s explore this idea further.

Working effectively with legacy tests

A couple of years ago I read a book from Michael Feathers that kept on being mentioned a lot in the literature I was reading then. The title? Working effectively with legacy code. Feathers makes some points on how to get code without tests working, by breaking down dependencies, introducing seams, and working towards more testable code. I loved that book.

When we take the idea of test automation as software development seriously, then there also should be a concept called legacy tests. That concept to me is related to testing debt, a term I think I coined back in 2009. But what are legacy tests? How do they slow down your productivity? And what can we do about it?

Here are some limited experiences I made with a couple of legacy tests, and how to overcome them. I hope this blog entry will trigger some more experience reports from folks, so that fewer teams need to suffer from it.

New names for the quadrants

In the past there have been multiple folks proposing a rename of the famous testing quadrants that Brian Marick wrote up a couple of years ago. Lisa Crispin and Janet Gregory labeled them Q1, Q2, Q3, and Q4 in their Agile Testing book. That naming misleads some folks as they think about a progression in the four quadrants. I recently read something that triggered a thought. I think we should rename these quadrant completely, and drop the counting digit at all. While several other folks have tried to find new names for the quadrants, I came up with a different thought: let’s try to find person names for the quadrants. Here is my first proposal for those.

What is Agile Testing?

While I was cleaning u my bag that I carry around with on various travels, I found the following notes. They were part of my introduction for the keynote at the Agile Testing Days 2012 in Potsdam, Germany. My talk was on “adaptation and Improvisation”, drawing an analogy from the famous geek movie “The Matrix”. I wanted to keep these notes somewhere. That’s why I decided to put them up on my blog. Hope you like it. Imagine Morpheus’ and Trinitiy’s voice.

ATDD in scaled agile environments

Years ago, I wrote a book on ATDD. Only years later I notice the value that this practice can bring to an environment with multiple teams working together on the same platform. The connection to scaling agile in the larger enterprise wasn’t that obvious than it became when I started to dive deeper into how to scale agile. Though, most larger enterprise struggle with getting one team running, scaling has become the latest fuzz in the agile community. Let’s see why ATDD is relevant for this sort of environment, and how you can challenge your team colleagues about it.

Don’t try to run before you walk

I have to admit: I am German. Us Germans are well-known in the world to deliver good results. That said, we are very dedicated to deliver efficient results. There is one thing that troubles me about that. Having our main business in Germany, I often face questions with regards to efficiency while introducing agile methodologies. You can efficiently drive your car right into a wall. That would be very efficient, but unless you try to kill yourself, not very effective. The English saying ‘don’t try to run before you walk’ expresses this gallantly from my point of view. Let’s explore that thought.

Continuous Acceptance

Over the past year I ran a couple of Scrum trainings. At first I found it sort of funny to notice that amount of misconceptions that seem to appear in these various classes. Recently I figured that it would be more helpful to clarify some of them. Among one of the larger, and probably more manifested misconceptions regarding Scrum lies in the Sprint Review meeting. Let’s examine that one today. I am quite sure that someone has written about this before. I found that it would be worth to throw in my point of view as well.

Why should just the developers have all the fun?

Back in 2009 I attended my first coding dojo. It did not take long for me to realize that it was fun, and all the programmers in that setting learned a lot. Ever since I was convinced about what some call Deliberate Practice. It’s a practical exercise to help you learn a deeper understanding of a skill – most often accompanied with a mentor or coach that provides you feedback. Let’s take a look into various formats that are suited for testers.
