Additional Information


19:00 DevOps for Java Developers In recent years, how we approach development has dramatically changed with the rise of DevOps, Cloud Computing, and Container technologies. Learn how to take advantage of microservices, serverless, and cloud-native technologies as Ixchel shows you the latest DevOps techniques to create hyper-productive and successful teams.

20:15 Framework Agnostic REST API Testing. Throughout history, humans have been obsessed with analysis, that is, decomposing ideas and concepts into simple or composite parts, to later combine them ordered or connected to form a system in a consolidated manner. The coherent whole that results is considered to be more complete than what would be a mere collection of parts. Software development has shifted away from the monolithic architecture to a “micro” service / function approach.

Applications are collections of loosely coupled and relatively lightweight modular services that have little or no knowledge of the definitions of other separate components. These units are sometimes developed by different teams with a myriad of technologies each one with life cycles of their own. Hence there is a need to test multiple services at the same time while maintaining a usable developer environment.

In this session Ixchel will show you a collection of her favourite libraries and tools such as WireMock, RestAssured, TestContainers and others, that have made her app development experience easier and enjoyable.
