What we’re about
Monthly presentation nights providing technical presentations of interest to Java software developers, especially focusing on aspects of the Java language and JVM, system & application architecture, third party frameworks & components, as well as other areas of interest (e.g. career management, business-social skills, pizza, etc.).
All are welcome to attend our events – you do not need to be an ACM member!
We do ask that folks RSVP to events here on Meetup so we can provide an attendee list to our host venue the day before each event. Additionally, please ensure that the name on your Meetup profile roughly matches your ID to ensure smooth admission to events.

Everyone loves writing tests, don’t they? How do you write good tests? What tools are available for you to write good tests?
In this session, I will dive into the many features of Quarkus that help developers write good tests. I will highlight some of the features of Quarkus, Dev Services and Continuous Testing, which help make testing easier. Additionally, I will live code some tests for common use cases developers encounter, including unit, integration, and “black box” testing of imperative and reactive RESTful and event-driven applications that use common services, such as databases and Kafka brokers. I will discuss techniques such as mocking, spying, and interaction-based testing/verification.
I'll even spend some time showing how IDE-based AI assistants can help!
Once you see how easy TDD really can be there isn't a reason to not do it!
Speaker:
Eric Deandrea is a Java Champion and Senior Principal Developer Advocate at Red Hat, focusing on application development technologies. Eric has over 25 years of experience designing and building Java-based solutions and developer training programs for the financial services and insurance industries. He is also a contributor to various Open Source projects, including Quarkus and Spring, as well as a speaker at many public events and user groups around the world.
Eric recently put his Quarkus and Spring knowledge to use by publishing his first book, “Quarkus for Spring Developers.” Outside of work, Eric enjoys boating on the lakes of New Hampshire, ice hockey, and martial arts, in which he holds a black belt in Kempo Karate.

Event Location:
Oracle
8 Van de Graaff Drive · Burlington, MA
---------------------------------------------------------------------Domain Driven Design is designed for implementing complicated business logic and is an excellent fit for microservices development.
Domain Driven Design provides a repeatable, logical structure that makes implementing business logic easier, faster, and more maintainable. Hexagonal Architecture (or Ports and Adapters) excels at producing loosely coupled, interchangeable components that fit well with DDD.
In this presentation I will introduce the Domain Driven Design and dive into the DDD concepts of Aggregates, Repositories, Value Objects, Services, Ubiquitous Language, Adapters, and Shared Kernels. I will also build an application using these patterns and leverage Hexagonal Architecture for easy extensibility. Testing will of course be included.
You will leave this presentation with a basic knowledge of Domain Driven Design, how to structure and test your application to implement DDD and how to use Hexagonal Architecture to extend your applications.
No slides; just live code.
