http://www.javahispano.org/portada/2014/6/17/charla-de-madridjug-tests-en-java-con-groovy-y-spock.html Andrés Viedma nos mostrará lo sencillo que es integrar Spock en un proyecto Java, y cómo su gran expresividad y la potencia de Groovy nos pueden ayudar a crear tests en los que puedas preocuparte más de qué quieres probar que de cómo tienes que programar la prueba, y que además sirvan para documentar de una forma muy elegante cuál es el comportamiento esperado de nuestra querida aplicación Java.

Groovy es un lenguaje dinámico y ágil que se ejecuta sobre la JVM. Con una sintaxis amigable, ofrece una extensión de Java que proporciona numerosas y potentes funcionalidades, consiguiendo una mayor productividad y haciendo la vida más fácil a los desarrolladores en su día a día. Grails es más que un framework de desarrollo de aplicaciones web, es una plataforma construida sobre otros frameworks y herramientas como Spring e Hibernate, con su propio ORM, con un tomcat y una base de datos embebida y, por supuesto, con Groovy como lenguaje. Juntos están revolucionando el desarrollo de aplicaciones web. ¿Quieres saber cómo? Te lo cuento en esta charla. ¿Quieres saber más? http://www.paradigmatecnologico.com

This workshop will introduce several examples on how to use GPars using abstractions such as : Actors, Dataflow, data parallelism... Software Engineer at Kaleidos MARIO GARCÍA I've been Java developer for 8 years and Groovy developer since 2010. Member of some Groovy User Groups (MadridGUG and DublinGUG) and also member of the Madrid Java User Group. At the moment happily working with Groovy at work, always trying to find new ways of using it. When I'm really bored I usually write something in my blog or twitter @marioggar. See you all at Greach.

It is not a static library though it must move with the times, and the Groovy times are moving to have static as well as dynamic compilation, and the use if the invokedynamic instruction. In this session we will look at some of the features of GPars and assess progress of Groovy/GPars for parallel execution. Of course GPars can also be used from Java, and Java is about to undergo the biggest revolution since Java 1 -- Java 5 was a minor change to Java in comparison. How does the Groovy and GPars cope in the face of Java 8? Independent Consultant RUSSEL WINDER Ex-theoretical physicist, ex-UNIX system programmer, ex-academic. Now an independent consultant, analyst, author, expert witness and trainer. Also doing startups. Interested in all things parallel and concurrent. And build.

It takes an opinionated view of building Spring applications, adopting convention over configuration as default. Add Groovy to the mix, and you have a web stack that will give you wings! In this talk we will: - Discuss the Micro Service Architecture. - Discuss the nuts and bolts required to build a Spring Boot Micro Service. - Test and write components with Groovy and Spock. - Run it on an embedded Jetty or Tomcat server. - Use Spring Data to interact with Postgres or MongoDB databases. - Use Cucumber with Geb for functional. - How to use Gradle to build. - Set up a Continuous Delivery pipeline in the cloud. - Automatically deploy the application to a PaaS platform. - Use Swagger spring-mvc UI to dynamically document the API. By the end of this session, participants should know enough to build their own applications and deploy them to the cloud with ease!

In this talk we'll mainly see runtime metaprogramming. I'll explain Groovy Meta-Object-Protocol (MOP), the metaclass, how to intercept method calls, how to deal with method missing and property missing, the use of mixins and categories. All of these topics will be explained with examples in order to understand them. Also, I'll talk a little bit about compile-time metaprogramming with AST Transformations. AST Transformations provide a wonderful way of manipulating code at compile time via modifications of the Abstract Syntax Tree. We'll see a basic but powerful example of what we can do with AST transformations. Iván López Engineer at Kaleidos Software Engineer and Systems Administrator with 11 years of experience.

Greach 2014, The Groovy Spanish Conf 28/March, Madrid, Spain http://greach.es Follow us on twitter http://twitter.com/greach_es Slides in http://greach.es/speakers/cedric-champeau-making-java-apis-groovy One of the major advantages of Groovy is that you can leverage existing Java APIs very easily: you can use them in Groovy just like you would in Java. However, Groovy is a perfect fit for DSLs and it's possible to make those APIs rock: why would you be obliged to use them in a Java fashion if we can build Groovy APIs for them? In this session, we will take an existing Java API and try to make it Groovy step by step, introducing you to various DSL building techniques in Groovy. After this talk, you should be able to build your own Groovy wrappers around existing Java APIs and offer them to the community! Cédric Champeau Core Groovy committer Cédric Champeau is a core Groovy committer. He joined SpringSource, a division of VMware, in order to help developing the language. Prior to that, he spent several years at Lingway, a software editor, where he used Groovy in multiple industrial contexts including DSLs for natural language processing, scripting or even workflows. He his currently working on the implementation of static type checking and static compilation for Groovy 2.0.

What makes this technique different is that it engages Stakeholders from start to finish of a project. This is done by writing Specifications by Example in collaboration with all Stakeholders. This presentation will use Cucumber combined with the power of Groovy to demonstrate how you can apply BDD to your next project. We will look at using Cucumber in context of both Groovy and Grails applications. We will demonstrate how to use Cucumber's Gherkin syntax to write clear Scenarios, then progress to writing Step Definitions in Groovy, then using Geb to interact with a browser. We will implement the new feature in our Grails application using Spock to test drive our finer grained components. Lastly, we will demonstrate our Cucumber Feature running end-to-end. The purpose of this presentation is to encourage others in the Groovy community to embrace BDD, and to write relevant useful applications Marco Vermeulen Private Contractor Marco Vermeulen is a South African Software Developer who works and lives in London.
