Bye Zürich! I had an amazing time at @voxxedzurich.bsky.social today! Learned cool stuff from the presentations I’ve seen myself and I left the stage with a huge gratitude. I’m so thankful for the atmosphere in the audience during my talk and I had some great interactions with attendees. Thank you!

@maarten-vandeperre.bsky.social getting dressed up live on stage during #vdz26 This looks like progressive enhancement to me! This talk by him and @lutskedev.bsky.social was fun to attend and very useful to see what you have to keep in mind when generating code with AI! Good Job!

I am so ready for @voxxedzurich.bsky.social today, but the real question is, are you ready for me? Join me at 11 for my talk where I’ll demonstrate some simple techniques that will help you gain confidence in your unit tests. #vdz26 #javaconference #unitsocializer

The sky is the limit! That’s what I was thinking when I submitted my talk for @voxxedzurich.bsky.social And as you can see on the photo… I made it! Join me tomorrow for a talk about how you can improve your unit tests! Make them test the right thing, the behavior! #sociableTest #unitsocializer

Version 1.1.0 of UnitSocializer was released last week. This release contains minor dependency changes to allow it to be used with Java 25. I also added support for the JUnit @Nested annotation. More info can be found here: wouter-bauweraerts.github.io/UnitSocializ...

We all know writing tests is important to ensure that our code behaves as expected. Tests should not only ensure that our new code is correct, but they should also serve as a means of detecting…

Are you sick of failing unit tests during #refactoring? We should be able to rearrange the code without altering the behavior. But how can we ensure this if our tests fail? Let's redefine the unit, focus on testing behavior and join me in the #sociable test revolution! www.canva.com/design/DAG4l...

With agentic AI and modern LLMs, anyone can now create apps. While AI-generated code improves, developers remain crucial. Many developers dislike writing tests, which leads them to rely on AI for test generation. However, trusting AI to test its own code is problematic.

Tonight I'll be attending and presenting at the #BeJUG #meetup in Ghent. I will talk about how you can write robust tests with only some minor changes in your test setup! I'm also curious to learn more about FFM on Raspberry Pi! I hope to see you there! #java #community

Had a great first day at #GoTechWorld in #Bucharest with a great talk about #GithubActions! The Speaker/exhibitor party afterwards was also a great moment to meet new people. As we should… we ended up in the bar of our hotel for a good closure!

Last week, I elaborated on requirements. But to create good software solutions, developers also need good Acceptance Criteria! Read about the rules for acceptance criteria here: www.canva.com/design/DAG2D... #softwareDevelopment #quality #userStory #requirements #acceptanceCriteria #bdd #tdd

Next week I'll be attending the #GoTechWorld conference in #Bucharest. Here I'll be speaking about how you can easily improve your unit tests. If you're also there, you're welcome to come and find me for a quick chat and a cup of coffee! #conference #speaker #openSource #quality

Software developers are great at solving problems! However, they need to know exactly what problems they should solve. To do our job, we need good user stories of which requirements are the core! What are #requirements? Link to more details in the comments! #softwareDevelopment #quality #userStory

Hey #developer! Do you suffer from test failures when #refactoring? I dare you to investigate your #unitTests. I'm confident that you will find your tests using a lot of mocks! These #solitaryTests tend to break when refactoring. Why don't you try #sociableTesting? #java

Just had the opportunity to present how you can easily write robust unit tests. Tests that help you change your code with confidence, without fear of breaking things. Thanks @rotterdamjug.bsky.social and @royvanrijn.com for having me!

Tomorrow I'll be presenting at the RotterdamJUG meetup! I prepared an inspiring session about how you can improve your unit tests, making them less fragile when you make changes or refactor your code! I hope to see you there! Check the meetup event for more details! www.meetup.com/rotterdamjug...

Dealing with legacy code is inevitable code. Sometimes it's well-structured, but often it's poor quality, like spaghetti, with testing gaps. When refactoring legacy, apply "Golden Master" or "Lift Up Conditional" to increase confidence in maintenance. #softwareDevelopment #legacy #quality

I just released both 5.5.0 and 5.5.1 of instancio-fixture-builder release for compatibility with all recent #instancio versions. No major changes in the fixture builder concept, just had to do some version updates! Support for Java 25 (LTS) is on it's way! #testdata #opensource #instancio

At The Beehive, we value teamwork over individual efforts, a belief shared by Jumbo Visma - Lease a Bike. They know their riders excel through collaboration. They've created The Wingbeat jersey for a major cycling event, inspired by a beehive's unity. Together, we are unstoppable! Go for it, Wout!

No fun without fundamentals! We all like to use frameworks and libraries. But often we don't need them, basic language features can often solve the problem! Skipping the fundamentals often leads to suboptimal solutions without understanding the impact! #programming #craftmanship #learning
