Serious Communication

Communication, quality, Testing

Yesterday, on the twitters, I had this conversation about communication with Michael Bolton:

Communication With Michael Bolton


It’s a simple answer. It is an easy answer.

And yet, when the tester asks “What exactly do you mean by soak testing?” they are likely to get non-answers. The manager may at first act like the answer is obvious, that everyone knows what it is. Another common response is for them to say “You know, soak testing”, with a slight laugh, making it socially awkward for you to say “Oh course I don’t know, that is why I asked.” If you persist the manager may shift, to say that you, the tester, are the expert. If they are willing to admit they don’t know either, you get to go to the next level. At some point, someone becomes afraid of you talking to “their” customer, and the communication stops.

Now what?

After twenty years of doing this and helping others do it, I have developed a handful of tricks.

Read on, dear reader. Read on.

On Test Maturity

Matt Heusser Matt Heusser Profile: Matt Heusser
Software testing, Testing

The work here is by no mean exhaustive. There is no mention of reporting or feedback or repeatability or training or process. It is simply how people think about risk.If you want to get better at software testing, you might start out looking for a test maturity model, maybe the one from the Illinois Institute of Technology that became the TMMi.

Wait! Before you click that link, stick around. I’ve got a better today.

Today I’m going to propose a way to think about tester maturity. One you can use to evaluate candidates, yourself, and yes, the overall culture of the organization. It is a model, which means it a general. All generalizations have exceptions. All generalizations are wrong. Still, if it can help you test better, interview better, hire better, then I would suggest that less wrong is better.

Here’s my proposal: A test maturity model that is less wrong. Continued »

Regression Testing Redux

Matt Heusser Matt Heusser Profile: Matt Heusser
Regression testing

This week I was at SauceCon, the annual conference for Sauce Labs. Sauce provides the grid (and cloud of mobile devices if you want them) to run selenium scripts on. Listening to a speaker talk about “testing” without drawing a distinction between regression testing and story-testing, I put out this tweet:Regression Testing

I know, I know, there are all kinds of testing, not just those two, how dare I forget about performance and security and so on. Here I am, being terrible, “just” talking about “functional” testing. Okay, fine, but not my point.

Today I just want to make two tiny distinctions, and explain why they are important.

The Data Comparator, Your Long Lost Friend

Comparator: Dolls

It seems like every time we do large-scale test tooling, we also end up writing a data comparator program. That is, program to compare two different things to determine if they are the same in the ways that matter. No, that’s not a typo. The middle step, where we “zero out” the differences that do not matter, is something I call data swizzling. Sadly, when I talk about data swizzling, most people think I am talking about data on how to cook a steak.

This problem of how to compare the “different” to determine if the differences “matter” turns out to be an incredibly common problem in software testing. Without the terms and concepts, teams generally end up inventing their own way of doing it, writing code that eventually becomes a gnarly mess. They reinvent the wheel.

Here’s the basic use case for a comparator, and how to do it.

To a programmer, DevOps typically means automating operations with Build/Deploy pipelines. I find that definition unsatisfying. The “right” answer, that DevOps is a culture change toward collaboration, isn’t much better. That second definition is vague enough that nearly anything can call DevOps. It is also vague enough that people can fundamentally disagree on premise and conclusions, talk “past” each other, and think they agree. One term for this is shallow agreement, and it’s terrible.

Eleven years since DevOps became big enough to have its own conference … e don’t know what it means.

Today I’d like to give up on defining DevOps. Instead, I’ll skip past it and introduce something even better: BizDevTestSecHRPRMarketingOpsOps.

That’s not a joke. Or, at least, it is not entirely a joke.

Let me tell you about it, starting with DevOps, but going very quickly.

The Cloud Bait and Switch

Matt Heusser Matt Heusser Profile: Matt Heusser
cloud, EC2, Kubernetes

When we started to talk about the cloud, twenty years ago, it was a picture on a napkin. We would draw one physical, concrete system, then an arrow, then a cloud. The cloud represented “the internet.” Its great power was that it was not concrete.

We did not know where the internet was. We did not know how it worked — and that was a good thing.

For the most part, though, we  rented servers in colocation facilities. These servers had IP addresses which would be listed in a lookup table called a Directory Name Service, or DNS. When you went to my website, www.xndev.com, your browser would do the IP lookup in DNS, translate www.xndev.com into, then go to that web page. To the casual yahoo! search-er, the computers were in the cloud. The rest of us knew all about the Linux Server in the data center. We had to choose between spending too much money on computer power, or occasionally getting overwhelmed.

That changed ten years ago with EC2. Suddenly the vendor claimed that could spin up as many servers as we needed. Run one server most of the time, then auto-scale when your company hit the front page of The Wall Street Journal. That was the promise, at least.

Today we have Kubernetes, an open source cluster manager. Kubernetes takes the mystery out of auto-scaling – showing that it is more art than science.

A Technical Debt Secret

Matt Heusser Matt Heusser Profile: Matt Heusser

Eleven years ago I co-organized the first Workshop On Technical Debt with Steve Poling; Michael Kelly was our facilitator. Since that time I published a cover story for Better Software Magazine on the topic and continued to work in the field. It is common for me to perform consulting and contract assignments and hear the term. Sometimes management listens; sometimes they don’t. Programmers might slag on the work done by the previous programmers. Sometimes the programmers are talking about their own work.

In all that time, I have noticed something startling.

Whenever people are talking about “technical debt”, there is invariably a programming skill issue involved. Continued »

Getting Git

Git, Programming, Version control

Last month I wrote about that hiring for technology is sort of like hiring a juggler. Sure, you can ask where they went to clown college and if they can crunch an apply while juggling. Or you could just ask them to juggle. Today I’ll talk about how to show you can juggle. Specifically, prove that you get git.

Github is a source-code-in-the-cloud platform that is free for individual contributors and non-profits. Putting your github link on your resume/linkedin shows that you know the basics of git. You can also use the tool to create a portfolio of your work. If you aren’t a programmer, it will generate you street cred with programmers and former programmers. If you are a programmer, it answers any questions about your git skills with finality.

Graphic Designer, Journalist, Manager, doesn’t matter. Over a period of two lunch hours, you can figure out what to turn into portfolio work, and learn enough git to put your portfolio in the cloud.

The best way to get hired is to show, not tell, your work.

Here’s how. Continued »

Engineer Mindset, Entrepreneur Mindset

Matt Heusser Matt Heusser Profile: Matt Heusser

The Entrepreneur and the EngineerIt’s been eights years now since I took Excelon Development full-time. In that time I’ve had the pleasure of deal with slow-paying customers, not-enough customers, an employee or two, and a whole lot of of contractors. I’ve also had the ironical pleasure of reading about the “Entrepreneur mindset” and worked with a few companies that were ” Entrepreneurial” or “scrappy.” As a technical person who does a great deal of the work himself, I see the two mindsets clash — sometimes in my own mind!

That clash, the confrontation between builder-of-the-thing and builder-of-the-company, can destroy a project. More importantly, it can destroy a relationship. Let it fester and it might even destroy a person, leading to depression and low self-worth.

Sometimes, the different can lead to an incredibly pairing. For every Steve Jobs, co-founder of Apple Computer, you probably need a Steve Wozniak. Continued »

Ping with payload

Communication, Email, IM, Ping

Ping with PayloadIn real life, it’s considered rude to start a conversation, or “ping”, by asking for a favor. Instead we start with a check-in – a human connection. We ask what’s new and about the kids. Finally, after we have re-connected as people, Donnie or Christine or Dawn at the bank will ask what business we can do today.

That might work in real life, but it’s death for productivity in an office setting.

Today I’ll teach you how ping with payload can save you hours a day — at a cost of seconds. Continued »
