Speaking in 2017

What’s the sandbox, what code you can run out of the sandbox, what’s the problem with that, how to fix it, and how to create a policy file

You don’t write OOP, many frameworks (e.g. Spring) are not OO, what is OOP, example of a bank account model, how to evolve from traditional Spring to OOP Spring, and benefits, drawbacks

Despite being very new, Spring Boot has seen a spectacular start as an amazing kickstarter for Spring-based application. You can now start your project in a matter of minutes, not days! On the other hand, you’re still using Java, with all its ceremony regarding code… Wouldn’t it be great if we could pair Spring Boot with a powerful yet simple language? In this talk, I’ll live code a Spring Boot application using Kotlin, the friendly language provided by JetBrains. Come discover how you can now cut through all the boilerplate and finally focus only the important code – the business code

This session will review Nicolas Fränkel's book: Integration Testing from the Trenches. We will cover the last 4 chapters: Testing Integration with Web Services, Spring in-container testing, Spring Web MVC testing and Java EE testing.

With the Spring Boot stack you can kickstart your Spring project in a matter of minutes. For both developers using Spring and microservices adopters, Spring Boot has been a resounding success. Favoring Spring Boot over the traditional Spring Framework comes at a cost, you have to let Boot be in control and it might hurt when you decide to get back in the driving seat. Come and discover how auto-configuration and the different flavors of conditionals work through the creation of a Spring Boot starter. You’ll come away with an understanding of Spring Boot internals, how to debug better, and be able to develop your own starter.

This session will review Nicolas Fränkel's book: Integration Testing from the Trenches. We will cover the first 5 chapters: Foundations of testing, Developer testing tools, Test-Friendly Design, Automated testing and Infrastructure Resources Integration.

Bien que relativement récent, le framework Spring Boot connait un succès spectaculaire. On peut maintenant démarrer un projet Spring en quelques minutes au lieu de quelques jours. D'un autre côté, vous utilisez toujours Java, avec son côté un peu verbeux. Ca ne serait pas sympa de pouvoir combiner Spring Boot avec un langage simple mais expressif ? Dans ce talk, je coderais une application en live avec Spring Boot et Kotlin, le langage fourni par JetBrains. Venez voir comment il est possible de se passer de toute la cérémonie du langage Java pour se concentrer sur la logique métier.

In this talk, I’ll live code a Spring Boot application using Kotlin, the friendly language provided by JetBrains. Come discover how you can now cut through all the red tape and finally focus only the important stuff.

Kotlin is one of those 'new' JVM languages that are currently rocking the boat. Although it’s made a great impact on Android, it’s equally good on the server side. As Domain-Specific Languages are constrained by the language they run on, Kotlin frees developers from Java fluent builders to propose something better. Taking the example of a Vaadin UI DSL, I’ll demo how one could design its own DSL with Kotlin.

What good would it be to put data into Elasticsearch and leave it there untouched? At some point, data needs to be put to (good) use, and the best way to do that is to display it in a graphical way. In this session, I'll show some of Kibana's features to achieve that.

Spring Boot has seen a tremendous increase of usage since its inception. Developers like it for its default convention over configuration approach that improved project setup time. Ops like it for its friendly monitoring endpoints. But there’s more to that.

Unit testing ensures your production code is relevant. But what does ensure your testing code is relevant? Come discover mutation testing and make sure your never forget another assert again. In the realm of testing, the code coverage metrics is the most often talked about. However, it doesn’t mean that the test has been useful or even that an assert has been coded. Mutation testing is a strategy to make sure that the test code is relevant. In this talk, I will explain how Code Coverage is computed and what its inherent flaw is. Afterwards, I will describe how Mutation Testing work and how it helps pointing out code that is tested but leave out corner cases. I will also demo PIT, a Java production-grade framework that enables Mutation Testing.

Who can ignore microservices in 2017? Everybody is talking about them and telling how they will save your projects and your organization. However, nobody is telling you about the cost of implementing microservices. After attending this talk, you’ll be able to decide by yourself whether microservices is the right architecture for you.
