Todos estamos escribiendo tests y tenemos controlado el Code Coverage, pero un 100% Code Coverage solo significa que todas las líneas se han ejecutado al menos una vez por nuestros tests, pero no dice nada sobre la precisión de los tests o la integridad de los casos de uso, y es por eso que el Mutation Testing es muy importante. MutationTesting se utiliza para diseñar nuevos tests y evaluar la calidad de los tests existentes. La idea es modificar el código cubierto por tests de forma sencilla, comprobando si el conjunto de tests existente para este código detectará y rechazará las modificaciones. Cada cambio en el código se llama mutante y da como resultado una versión alterada del programa, llamada mutación. La calidad de los tests se mide en función del porcentaje de mutación eliminada. En esta sesión veremos como se puede hacer Mutation Testing en Java con Pitest, modificar su engine para reducir el tiempo de ejecución y como usarlo en proyectos multi-module. ¿Quién es el ponente?

"Me especialicé en redes pero la programación siempre fue algo muy atrayente para mí. Comencé con .NET y acogí #NodeJS desde casi sus inicios. He desarrollado principalmente #mobileapps pero actualmente estoy en entornos de desarrollo web :P Soy un entusiasta de las tecnologías, me encanta entender los diferentes lenguajes de #desarrollo, como .NET, Kotlin, #Java, JS/TS, Swift entre otros y utilizarlos para desarrollar nuevos productos. Mi intención es explicar la evolución de un proyecto cuando te incorporas a una startup donde hay un codebase heredado, haciendo una crítica constructiva acerca de #JS y centrándome en la evolución de #ExpressJS a #NestJS y los beneficios que esto aporta, mientras el negocio continua y hay que aportar valor." ✉ Suscríbete a nuestra 𝗡𝗲𝘄𝘀𝗹𝗲𝘁𝘁𝗲𝗿 𝗚𝗲𝗲𝗸 y recibe mensualmente formaciones gratuitas, entrevistas exclusivas a referentes del sector, novedades tech para estar al día, eventos e invitaciones y regalos exclusivos: https://geekshubs.com/comunidad/ #comunidad-newsletter 💼 ¿Estás buscando un nuevo proyecto profesional o necesitas incorporar perfiles tech a tu equipo?

Improve your architecture with the Modularity Maturity Index (MMI). Complete talk by Carola Lilienthal on #GSAS22 In the last 20 years, a lot of time and money has gone into software systems that have been implemented in modern programming languages such as Java, C#, PHP etc. The focus in the development projects was often on the quick implementation of features and not on the quality of the software architecture. This practice has led to an increasing amount of technical debt – which is unnecessary complexity that cost extra money in maintenance – accumulating over time. Today these systems have to be called legacy systems, because their maintenance and expansion is expensive, tedious and unstable. This talk discusses how to measure the amount of technical debt aka unnecessary complexity with the modularity maturity index. The modularity maturity index (MMI) of a code base or the different applications in an IT landscape gives management and teams a guideline for deciding which software systems need to be refactored, which ones should be replaced, and which ones don't need to worry about. The goal is to find out which technical debt should be resolved so that the architecture becomes sustainable and maintenance less expensive.

En esta charla, el committer de Micronaut Álvaro Sánchez-Mariscal, demostrará cómo se pueden construir rápidamente microservicios optimizados con Micronaut y GraalVM Native Image. Los asistentes aprenderán cómo la combinación de GraalVM Native Image y Micronaut puede dar lugar a aplicaciones eficientes, de alto rendimiento y optimizadas que pueden ser perfectamente desplegadas en entornos como Kubernetes o plataformas serverless. Habrá una sesión de programación en directo de una aplicación Micronaut utilizando Micronaut Data JDBC y GraalVM. Info del ponente: Álvaro Sánchez-Mariscal, Principal Member of Technical Staff, Oracle. Álvaro is a passionate developer and agile enthusiast with over 21 years of experience. He is now a Principal Member of Technical Staff at Oracle Labs, where he is a Micronaut committer, helping to maintain and evolve the open-source framework. Before that, he was a Staff Engineer at VMWare, where he led the creation of new products to build, package, verify and publish software solutions with confidence in the VMware Marketplace. Previously, he spent some years working in different industries like gambling games (Odobo) and fintech (4Finance). Prior to that, he created his own company, Salenda, in 2005, a software factory and Atlassian Solution Partner headquartered in Madrid, Spain. Adaptavist acquired Salenda in 2019. Previously, he worked at companies like IBM BCS, Sun Microsystems or BEA Systems, where he was recognised as BEA Technical Director, an MVP awards program. He was also one of the initial founders and member of the Board of Directors of javaHispano in 2002, the world's largest Spanish-speaking Java User Group. Álvaro has spoken in 11 different countries at conferences like Devoxx BE, GeeCON, JavaLand, JavaZone, Codemotion and Commit Conf. In his spare time, as well as coding and experimenting with new technologies, he likes to spend time with his wife and children, support CD Leganés football team, and play paddle tennis. ------------------- Síguenos en nuestras redes para enterarte de las próximas charlas: - Twitter: https://goo.gl/MU5pUQ - Instagram: https://lk.autentia.com/instagram - LinkedIn: https://goo.gl/2On7Fj/ - Facebook: https://goo.gl/o8HrWX

Most often, Java developers are very skilled when it comes to programming languages, design patterns, frameworks and everything that's related to their programming language of choice. However, the database is still uncharted territory, usually treated as a black box that we throw queries at and expect it to respond in no time. With this workshop, Vlad wants to get Java developers to know more about RDBMS so that they can design their application data access layer accordingly. After attending this workshop, you'll know all sorts of tips that you can readily apply to your current enterprise project.

Spring for GraphQL es el proyecto de la comunidad para manejar de manera sencilla todo lo relativo a GraphQL en una aplicación Spring, tanto en el servidor como en el cliente. Su versión 1.0.0 apareció en mayo de este año y es compatible con Spring Boot 2.7.x; acaba de liberarse la milestone 1.1.0 de cara a la salida GA de Spring Framework 6 y Spring Boot 3, en poco más de un mes. En este webinar presentaremos brevemente el lenguaje GraphQL. Luego construiremos un sencillo servidor con Spring y Java y lo consultaremos tanto desde Postman como desde la UI integrada (Graphiql). Por último, haremos un cliente web reactivo (GraphQlClient) para consumir nuestra API por HTTP. ¿Quién es el ponente? Julio César Estravis Barcala. Empecé a estudiar Java en 2012, cuando el “for-each” era una novedad rutilante. Sociólogo y agitador cultural en su Buenos Aires natal, me desempeño profesionalmente como programador informático desde mi relocalización en Madrid hace tres años. Vivo en Alcalá de Henares con mi pareja Victoria y mi perro podenco Poirot, descendiente del detective belga.
