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...

I'm glad to announce that I will be present at Voxxed Days Zürich in 2026, so I can enjoy engaging sessions, meet the local #Java community and catch up with other speakers. #VDZ26 #unitTest #UnitSocializer More details about my session can be found here: vdz26.voxxeddays.ch/talk/?id=2508

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

You can’t attend an @rotterdamjug.bsky.social meetup without making a detour to enjoy this beautiful bridge by night

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...

🚀 BeJUG is back in Ghent this November! Big thank you to Inetum (www.inetum.com/en/belgium) for hosting us! Speakers are @frankdelporte.be and @wbauweraerts.bsky.social. Looking forward to what they have to share! Sign up here: www.meetup.com/belgian-java...

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

A brand new #JAVAPRO Special Edition has been released. However I enjoyed the previous issues, I love this one even more! Amongst interesting articles of very skilled people, you can also find my article about how I think about #testing! Download for free at javapro.io/2025/09/30/0... #java

Throwback to a great time at @lu.voxxeddays.com with amazing pictures by @ddoutsiopoulos.bsky.social How many days until the next edition? I can’t wait!

Time files! @lu.voxxeddays.com is over for me, but I had an amazing time, learned cool stuff, gained more #insight and did Some #liveCoding. Also murphy was present, but I managed to make my point, and I enjoyed every second! I’ll be back! #conference #java #testdata #knowledgeSharing

It’s the final countdown! One more session before I’ll hijack the main stage @lu.voxxeddays.com This talk fits for all levels. I promise that there will be something new for all of you! Join me on a trip trough space and time exploring data generation techniques! #java #OpenSource #testData

Back to the main stage, wouldn’t want to miss @sanderhoogendoorn.bsky.social talking about the habits of a successful team @lu.voxxeddays.com #conference #teamwork #softwareDevelopment

First take-away from today sessions at @lu.voxxeddays.com How can you share your insights with your customers or stakeholders? Just apply the #JustSharing principle! justsharing.dev #keynote #sharingIsCaring #conference #learning

#VoxxedDaysLuxembourg has finally started! Two days filled with new learning, meeting interesting people, making new friends and talking about my passion! It will be AMAZING! #conference #java #java30

Proud to be a part of this! Not only it will be my first talk in another country, I’ll also try some live coding for the first time. One thing is for sure! It will be an opportunity to learn for everyone! Join me for my talk at #VoxxedDaysLuxembourg ! #testdata #conference

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!

Exciting news! I'm thrilled to announce that my presentation, "Generate Test Data Like a Boss!", will be available as a video on demand for the WDI 2025 conference. Session will be available on the conference platform on april 4! Make sure to check it out! #WDI #conference #testData

New version of instancio-fixture-builder! Introduced the toFixtureBuilder method, inspired by lombok. This enables you to create a fixture builder from an existing object!. Don't miss out on it!

Last Friday, I had the pleasure of attending the internship fair at KdG. It was fantastic to meet the students. I can't wait to find out which teams will be assigned to us, so we can help them unfold their wings and explore their full potential! #internship #mentoring

#instancio has released version 5.3.0, necessitating an update to the instancio-fixture-builder, which is also being launched today! Check it out and streamline your #testdata generation in your #unittests with #java

#UnitSocializer is shaping up! Today I came up with some new ideas, to make it even easier to write sociable tests. Not ready to be released, but soon it will be! #TDD #java #testing #sociable-test #opensource

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

I released a new version of instancio-fixture-builder. It now includes an annotation processor that autogenerates the AbstractFixtureBuilder implementations, significantly reducing boilerplate code! Details: wouter-bauweraerts.github.io/instancio-fi... #tdd #instancio #testdata #java #programming

Proud to announce that my application for #JavaproMagazine has been accepted! Can’t wait to see my first article being published.

New version of instancio-fixture-builder (5.2.1) has been released. This version brings nothing new, but only has updated dependencies to make it compatible with the latest #instancio version. central.sonatype.com/artifact/io.... mvnrepository will follow soon. #opensource #testdata

Newsflash! My most recent brainchild is almost getting to the point where it can be released! I’m currently working on an #opensource tool that simplifies the creation of #sociableTests. This first release Will work with #JUnit and #Mockito. Only some minor tasks left!

Today I had the opportunity to host a guest lecture @ KdG community college. I had an amazing time speaking in such a beautiful room! I hope the attendees had a good time while learning something new! #tdd #bdd #softwareQuality #testing
