Testing inside agile development cycles

Dear America

as a citizen of Germany all of my life and a past scholar of the German school system I have learned about the past of our mistakes in our history. The mistakes of my grandparents and great-grandparents and how Adolf Hitler came to power at some point in our history, leading to a collapse of the institutions I have known for good all my life.

The whole system started to fall apart based upon a lie, the lie that the Jewish people were to blame for all the suffering out there. Soon, the conversation shifted from blaming Jewish people to blaming other folks. Or in the words of Pastor Martin Niemöller:

First they came for the socialists, and I did not speak out—
     Because I was not a socialist.

Then they came for the trade unionists, and I did not speak out—
     Because I was not a trade unionist.

Then they came for the Jews, and I did not speak out—
     Because I was not a Jew.

Then they came for me—and there was no one left to speak for me.

Or in the words of the past Gerald M. Weinberg:

If you solve problem no. 1, problem no. 2 gets a promotion.

Watching the events unfold in your country has bothered me for the past five years. The parallels are striking at times, even though you are foolish enough to do your own mistakes and neglect them as often as I find parallels.

The events that happened now half a year ago, exactly 6 months to the date of my publishing this blog entry, you should listen more to what history can teach you. I still see you promoting a lie so intense that can become the downfall of your society. I still see you promoting falsehoods for the good of a few, rather than taking into consideration the goodness of your people or humankind in total. I still see you dragging yourself into the end of the democratic experiment that started more than 200 years ago on a daily basis.

Please consider my words moving forward. Not necessarily for me, but mostly for you. While I believe that a stable America may help in (re-) building a more stable world overall, I fear for the outcomes of the alternative reality that I see you heading towards.

Kind regards

a concerned German.

A tale of history

Disclaimer: The following story might be disturbing to some of you, especial if you happen to live in the United States of America right now. It’s more on the political side of things, rather than dealing with my more professional life. The sole reason for this is that I cannot keep my mouth (or blog for that matter) shut to the things that are happening around us today.

Hitler’s Signature

About nine years ago, my family bought a house that we hopefully will own directly at some point. It’s a rather old house, built in 1938, so I knew what we were setting up for when we made the deal. I knew I’d need to add new isolation, maybe new windows, and eventually replace the heating system that was roughly 20 years old at the time.

Step forward a few years, and it became clear we needed to replace the heating system. Not because it was failing, but because the chimney was getting wet to the point where the water came back into our living places. The chimney was pretty small, so a fix by a pipe was not an option. We didn’t have the means to buy a heating system right from our pockets, so I seeked to get a support program for replacing the old heating.

In Germany, that meant to get an assessment from an energy consultant. I made an appointment, brought the documents from the house construction with me, and let her dive through them. At one point, she called out: “Omg, the Führer signed this one.” And indeed, right on the first set of construction documents, there was Adolf Hitler’s signatory on it. I couldn’t believe it.

Then the consultant explained the circumstances to me. Back in 1937, the regime wanted to set up a military training ground in a village nearby. That military training ground still exists as of today. However, there was a small settlement of people in that area, so they relocated them. It turned out, that we bought one of the houses that were built for that matter. The houses left and right to ours have the same basic construction and were built for the same reason.

But this isn’t a story about our house or the neighbors’ houses.

Military training ground

There are public opening hours for the military training ground. As of today, German and British tank divisions use it for training purposes. At my first job, I found that the way to work was way more efficient when driving during public hours over that tank training ground rather than using the public roads around it, so I have been on that property a couple of times. You can still see the old village structures on there. And I will never forget the day when I found myself in my small car among 20 tanks, 10 in front of me, 10 behind, and got quite scared.

The German military base nearby isone of the largest – if not the largest – and according to Wikipedia, serves 4.300 soldiers. The British division is located closer to Paderborn in Paderborn-Sennelager, while the German troops are located in Augustdorf.

The name of the German barracks is indicated as “Gfm Rommel Kaserne” on road-signs, and I regularly drove by those signs for many years on my way to work. A few years back, I watched a piece on TV about Third Reich area military names still in use today. That’s when it clicked for me. General Field Marshal Rommel refers to no other person than Field Marshal Erwin Rommel, probably one of the most evil leaders during the Nazi regime in Germany.

My parents visited with us the close-by Nazi concentration camp in Bergen-Belsen, and I remember how sick that made me as a teenager to go through that part of our history. It’s a piece of our piece that I won’t deny, but also a piece of our past that I hoped would not exist. Back when I was in my 20s, my father consumed TV stations with the history of that area. At some point, he told me, that he was doing that because he never got to know any of that from his parents. They were outright silent on it, so as an adult he was still curious. Both my grandfathers served in World War II, and one of them even went into captivity in Stalingrad.

With all that in mind, I was disgusted to find out, the close-by barracks were named after such a leader from the Nazi regime, and even worse, the naming took place in 1961, several years after the Nazi regime had fallen. The name is controversial and has been debated for decades, according to information on the website of the Bundeswehr (German). Personally, I think they should rename it, but it seems to be decided by our military leaders whether that’s going to happen.

But this is not a story of renaming the local military barracks.

What this story is about

Now, suppose chancellor Angela Merkel or President of Germany Frank-Walter Steinmeier were publicly announcing to keep the name of the military barracks to someone with a central role in the Nazi regime. A regime that killed several million people for reasons we consider outright wrong today. Don’t get me wrong, I think Field Marshal Rommel did do some achievements during his career. Is he worth remembering in this manner? I don’t think so.

Now, especially my American readers, go back to the moment where you read about me suggesting Angela Merkel would publicly announce to keep the name of the barracks, and your reaction to that. Go through this state of emotion one more time. How does your stomach feel? How does your throat feel like? What is going on in your mind?

This is the type of reaction that black Americans feel every day once they ride past a military barrack named after a military leader from your Civil War time. The is the feeling any non-white American has during an interview with your President when he puts renaming your military bases off the table. That is the feeling every black American has when being stopped by the American police force.

I don’t want to tell you what to do about it, as I think you probably already know.

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

Disclaimer:
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.
