Smarter testing and never waste time again.


Smarter testing and never waste time again.

The #1 programmer excuse for legitimately slacking off used to be “My code’s compiling”. 


These days it’s more likely “I’m running the tests”. We have time for a coffee (or two or three). That’s what we turn into code after all. 


We waste not only a lot of our time waiting until the very end of the build to see tests which we have just written failing, but also tons of resources making our CI servers sweat and having enormous queues of pending jobs. But what’s even more important - we switch contexts and thus we loose focus. 


Maybe we can test smarter? Join us in this workshop and bring your laptop to learn about a new tool we are working on that you stay in the zone and never waste time again. We know which tests you want to run.

Alex Soto, from RedHat will conduct this workshop . He's a usual speaker at the BarcelonaJUG events, as long as speaker in other big conferences like Devoxx, JavaZone, JavaLand, JavaOne...

DevOps for Adults: Setting up a holistic Continuous Delivery pipeline (12/9)

Hi dudes!
How are you? Hope all of you enjoy great holidays ;-)
We know that it is a bit hasty, but taking advantage that Michael Hüttermann will be the next week in our city, we have decided that it can be interesting to take advantage of his visit and just organize a talk with him (and start our particular back to school :-P ). 
Michael Hüttermann is Principal DevOps Consultant at CloudBees. He has written a couple of books including "DevOps for Developers", 2012, and "Agile ALM", 2011 and he was recognised to be a Oracle Java Champion in 2006 and a Oracle Developer Champion in 2017.

In this session we will interactively set up a holistic Continuous Delivery pipeline with the use of DevOps enabler tools, based on Cloud, microservices and container technologies. We’ll package a Java EE web application. Its development versions will be inspected and promoted towards production environment in the Cloud. Jenkins 2 with its native delivery pipeline features will serve as the major backbone of our DevOps toolchain glueing together other tools of the overall ecosystem.

So, sounds interesting for you? We hope to count with you and see you next Tuesday 12th at Codurance offices, so book your place in Meetup ;-)
Happy building!
PD: We haven't had time enough to announce this event in advance, hope you may understand... but we haven't notice the visit of Michael until the last minute :-/

Microservices development with Lagom

Hi devs !!!
Although we are finishing all the details for the JBCNConf , the JVM conference, that takes place next 19th of June, we don't stop organising events that we hope you will find interesting, with great speakers like Ignasi.
This time we've been lucky to host an event by Ignasi Marimon, about micro services and the Lagom framework next Thursday 8th of June at Ocado Technology offices.

"One microservice is not microservice, they come in systems" Jonas Bonér. With that premise in mind, Lagom is a framework that enables microservice-based systems development heavy-lifting the issues implicit in a microservices system. This session will be a 3 hour workshop where we'll review some opinions that affected the design of Lagom and we will also create a basic multi-service application. Please make sure to bring your laptop to follow along.
This is a hands-on workshop which requires some initial setup. Please follow the Getting Started guide for Java/sbt in the docs to make sure your machine is fully setup. 
As we have a limited space for this workshop, please register in our Meetup event.
Register !!!

Ignasi Marimón a well known developer, Software Craftman wannabe and coorganizer of the Scala Developers Barcelona group. Ignasi has a lot of background and experience developing in Java since 2001.

Hands on performance workshop (25/5)

Hi JUGgers!

Our Java & JVM Barcelona conference is almost there, but we are not going to stop just because of it, right? ;-)

One year ago we had a talk about Performance on the JVM, do you remember? Well, we thought that it was good to move on with the basics and play a little bit with software in order to settle all the concepts. That's the main reason behind this workshop, hope you will enjoy it ;-)


This introductory workshop will be driven by Galo NavarroGuillermo Ontañón and Duarte Nunes and it is designed for developers who can write Java, Scala or any other JVM language, but have zero practical experience on performance analysis. After this workshop you'll take away hands on experience using diagnostic tools, profilers and writing micro benchmarks based on practical examples, all of which you can start applying on real projects.

The workshop will be very hands on so it's strongly advised that attendants are able to bring and use a laptop (preferably Linux or OSX.) ready to build Java projects.

About our speakers, Galo is a software engineer focused on scalability and distributed systems, mostly on the JVM. Currently working in Engineering Productivity at Schibsted, pior to that he implemented virtual networks at Midokura and social networks at Tuenti and Last.fm.


Guillermo is a software engineer specialized in systems / network / concurrent / distributed development on Linux. Java, Scala,C, C++, Python currenly working as a Staff Software Engineer in Schibsted Media Group.

Duarte Nunes is a Software Engineer working on ScyllaDB, where he develops a high performance, distributed database. He has a background in concurrent programming, distributed systems and low-latency software.

Finally, we have to thank once again to New Relic, because they have offered to host the event, and also they are going to invite us to some beers and pizzas! Thank you!


Nothing more, remember to RSVPed your seat and see you next 25th!

PS1: There are not too much free spots because this is a workshop and because of that it is not possible to have a large audience following it. Please, think twice if you are not able to come and free your spot.

PS2: Do not worry, we will announce soon the details about the pre-requisites you need in order to run the workshop smooth ;-)

JSF with Primefaces, from ugly duckling to a beautiful swan (6/4)

Hi !

March is not over yet and we are thinking on April for our next event ;-)

This time we'd love to receive the visit of Cagatay Civici next 6th of April when he will share his knowledge about JSF, server rendering and front end frameworks.

Cagatay Civici is a member of JavaServer Faces Expert Group in JCP, the founder of popular PrimeFaces and PrimeNG projects. He’s a recognized speaker in international conferences such as JavaOne and in many local JUG events around the world.



JSF has come a long way since its initial release and managed to catch up with modern web development model. Combined with the popular PrimeFaces framework, JSF unleashes its true potential.

This session takes you on a tour of modern component based java development with server rendering featuring rich set of components, responsive design, powerful Ajax APIs, a real-time push framework with websockets, a mobile web renderkit, the dialog framework, extensive client-side validation and attractive page layouts. Also, to end the session, Cagatay will show to the audience how to create an app in less than 15 mins ;-)

At this moment we are looking for a place so if anyone is interested in hosting the talk, please send us a message, we will be really happy to come ;-)

Hands-on Session : TDD in baby steps

Hi devs !!!!
We are not stopping at all !!!!! ( buffffffff ), now we come with an amazing workshop by Sandro Mancuso about TDD, next Wednesday March 8th.
Committing fast and often helps us focus on the behaviour of your system and allows for the design to incrementally emerge. It takes a lot of discipline to make your red-green-refactor cycles as small as possible so that you can commit often.

This exercise puts a time constraint of 2 minutes between every commit and if your tests fail when each two minute session is up then you must revert everything up to the last commit. It's guaranteed to frustrate you in the beginning, as it did frustrated us, but you'll be surprised how quickly you start getting used to it.

You'll need a version control system and language of your choice. Git is quite straightforward for this exercise but you can use your favourite. The actual Kata Problem will be introduced at the start of the session. 
We also want to mention the Open House event that Codurance will have on March 6th in its offices : https://www.eventbrite.co.uk/e/codurance-barcelona-career-open-house-tickets-32039652463  For developers who are looking for autonomy, mastery and purpose. Codurance Barcelona Open House next Monday 6th March at 18:30 at Codurance Office in Barcelona, Carrer Arago, 208 5th floor.
Sandro Mancuso, software craftsman, author, and founder of the London Software Craftsmanship Community (LSCC). Sandro has been coding since a very young age but only started his professional career in 1996. He has worked for startups, software houses, product companies, international consultancy companies, and investment banks. During his career Sandro had the opportunity to work in a good variety of projects, with different languages, technologies, and across many different industries. Sandro has a lot of experience in bringing the Software Craftsmanship ideology and Extreme Programming practices to organisations of all sizes. Sandro is internationally renowned by his work on evolving and spreading Software Craftsmanship and is frequently invited to speak in many conferences around the world. His professional aspiration is to raise the bar of the software industry by helping developers become better at and care more about their craft.
Hope to see you there !!!!!
