Greach is a yearly technical conference around Android, JVM Frameworks and alternative JVM languages. It brings together JVM developers with framework creators and international speakers. Developers learn about JVM languages such as Groovy, Kotlin, platforms such as Android, JVM frameworks such as Grails, Micronaut, Ratpack, Spock... or cloud environments such as Google Cloud, Amazon Web Services or PWS. The most talented developers around Europe come to Greach to learn how to develop better, faster and smarter. ------------- ------------- Todos los vídeos de Greach 2019 en: https://lk.autentia.com/Greach19-YT ¡Conoce Autentia!

How to build and test automatically our applications for each commit? How can we find those devices inside the company, whatever its size may be? Could there be a directory somewhere that lists those available devices? Could we use a device remotely and share it with other developers as if it were in the cloud? What if you could answer all these questions with the help of a low cost device farm that fits into a pocket? A pocket full of clouds... Poddingue, our proposal, aims to tackle this problem thanks to Docker, HypriotOS, Armbian, Gitlab CI and OpenSTF. It’s an internal solution made of OSS readily available, but it has not yet been publicly announced as a whole. This is a feedback about an idea on its way to production, a long journey full of different feelings : horror, happiness, suspense, boredom... This presentation won’t be too technical ; it is opened to anybody who has an interest into Android, exotic hardware or continuous integration, as long as you can stand a bad sense of humour. At the end of the talk, you should know how to build your own cloudy pocket farm of Android devices and how to use it to test your applications within your ci pipeline. ------------- Todos los vídeos de Greach 2019 en: https://lk.autentia.com/Greach19-YT ¡Conoce Autentia!

Groovy es un lenguaje dinámico para la JVM y la evolución natural para un programador Java debido a su baja curva de aprendizaje. Si quieres saber por qué programar con Groovy es una Hora de Aventuras, esta es tu charla. Aprenderás a través de ejemplos las principales características que hacen de Groovy un lenguaje tan potente y versatil: tipado dinámico, closures, manejo de listas y mapas, power asserts, builders, metaprogramación, scripting, DSL's, transformaciones AST y muchas más. Te aseguro que después de la charla tendrás ganas de profundizar y utilizarlo en tu día a día.

Puede que hayas oído hablar de Spock, el framework basado en Groovy que te permite hacer tus tests Java más legibles y expresivos. Pero seguramente no hayas visto una comparación de código real de tests hechos en librerías de test típicas como son JUnit y Mockito y cómo se harían en Spock, algo que realmente te haga consciente de lo que ganas, y lo que pierdes, al hacer tus tests con Spock. En esta charla no solo mostraremos eso, sino que repasaremos algunas recomendaciones de buenas prácticas típicas para los tests unitarios o de integración en Java, y veremos cómo se ven afectadas al usar Spock. Cómo algunas pierden importancia y hasta sentido, y otras nuevas aparecen para reemplazarlas. Cómo ahora puedes pensar más en el qué que en el cómo, cómo todo es más sencillo. Y cómo pierdes también cosas por el camino. ¿Te atreves a cambiar la forma de hacer tus tests?

¿Recuerdas esos días en los que testeabas utilizando JUnit? ¡Qué! ¿Todavía lo usas? ¿Es aburrido, verdad? Seguro que te inventas un montón de excusas para no testear tu código. Por suerte esos días pertenecen ahora al pasado porque Spock está entre nosotros. Spock es un framework de tests basado en Groovy que podemos utilizar para testear aplicaciones Java y Groovy que hace que escribir tests sea divertido otra vez. Podemos escribir tests totalmente expresivos, fáciles de leer y de mantener debido a su DSL y a todo el poder de Groovy. En esta charla tipo live-coding aprenderás por medio de ejemplos los conceptos básicos de Spock y verás qué fácil es testear aplicaciones Java. ¡Te advierto que después de la charla no tendrás ningún excusa para no testear tu código!

Habitualmente miramos dentro de nuestros programas -debug- en ejecución sólo mientras estamos creándolos. Una vez están desplegados en producción dejamos de tener acceso a las intimidades de los mismos. ¿O no? CRaSH es un shell interactivo dentro de nuestra JVM que nos permite inspeccionar todo lo que esta pasando, en tiempo real. YouDebug es un depurador no interactivo que nos facilita la obtención de información de los problemas justo cuando suceden. Pasen y vean lo que se puede hacer con estas dos herramientas basadas en Groovy (aunque no necesitemos conocerlo para obtener beneficios inmediatos) para encontrar problemas en nuestros programas.
