Meetup 9 december

Aanmelden voor deze meetup kan via

The Holliday season is about to start, Christmas is around the corner and we are close to the end of the year. We want to celebrate that with all the members of the Utrecht JUG, and what is better way to that with a meetup, food, and drinks.

17:30 Doors open
18:00 Buffet
19:00 Roy Straub – Why developers should ❤ their tests
19:30 Hinse ter Schuur – Mikado and the Art of Refactoring
20:00 Bouke Nijhuis – Why I prefer Spock over JUnit
20:30 Drinks

In this edition, we will show the highlights of our first Speaker incubator program. We will show what we did, how we continue and how you can join in 2020. Three of our own community members will give a talk about their passion in just 30 min each to convince you that you can do this too with a little help.

Roy Straub – Why developers should ❤ their tests

What is the reason you write your tests? To show that your code works? Probably. That’s a very compelling reason to write tests. But tests actually can do a lot more than just show the correctness of your program. Drawing from practical experience of applying TDD/BDD I have found much more, less obvious benefits that come with proper testing discipline. For instance I found that good tests allow me to speed up my development! During this talk we will explore this and other benefits and hopefully you will learn to appreciate your tests more. Who knows, you might end up loving them…

Hinse ter Schuur – Mikado and the Art of Refactoring

Do you know this feeling? Still struggling with a big refactoring… you promised your team that it would be finished within a day. But that was two days ago. You cannot just revert, because you already invested a lot of time. You have to go forward. But… the project is not compiling at all. If this sounds frightening familiar, this session is for you. In this session you will learn how you could avoid this situation by using the Mikado method. This method is about taking small steps, but it also guides the direction for those steps. You will see that by applying some simple rules you can enjoy refactoring, without the fear of getting stuck.

Bouke Nijhuis – Why I prefer Spock over JUnit

In my humble opinion Spock is a better tool for unit testing than JUnit. The presentation will give several examples to support this opinion. It will show you the areas where Spock shines. To be honest there are also things that JUnit does better, so there will be time for that as well. Finally I will show (with a little live coding) how simple and effortless one can start testing with Spock. At the end of this session everybody should be able to write their own Spock tests and more importantly everybody will be eager to try it!
