Hi. Specs2 is one of the most popular Scala libraries for testing, but definitely not a simple one. That’s why I’ve decided to create a blog post with a few tricks on how to make working with Specs2 much easier. The examples are 100% artificial, but their purpose is only to demonstrate the capabilities of Specs2. Read more

Akka Streams is an exciting new technology from Typesafe that is an implementation of the Reactive Streams specification. To this point two other implementations have been declared (from the Reactor team and Netflix’s RxJava team) but only the Typesafe’s implementation is mature enough to do some experimenting with it. This blog covers the 0.3 version of Akka Streams. You can find the API here

RabbitMQ is a messaging broker implementing AMQP 0-9-1 protocol. It’s known for its reliability, speed and simplicity in everyday use.

These two technologies seem like a perfect fit, so in this post I’m going to explore some basic integration possibilities and example usage. Read more
