Akka Cookbook

By: Vivek Mishra, Héctor Veiga Ortiz

Overview of this book

Akka is an open source toolkit that simplifies the construction of distributed and concurrent applications on the JVM. This book will teach you how to develop reactive applications in Scala using the Akka framework. This book will show you how to build concurrent, scalable, and reactive applications in Akka. You will see how to create high performance applications, extend applications, build microservices with Lagom, and more. We will explore Akka's actor model and show you how to incorporate concurrency into your applications. The book puts a special emphasis on performance improvement and how to make an application available for users. We also make a special mention of message routing and construction. By the end of this book, you will be able to create a high-performing Scala application using the Akka framework.

Testing services

Testing is always a crucial element in any software project. Untested code usually ends up turning into problematic code. In a large microservice architectures, a single service could be used by tens of others. Pushing untested code that might break other services is not what you want in your architecture. Lagom provides comprehensive testing support to make sure your services behave as expected before promoting them to staging or production environments. In this recipe, we will look at how to test a single Lagom service with the help of Scala test.

Getting ready

To step through this recipe, we need to import the Lagom Akkacoobook project that we created in the initial recipe of this chapter; all other prerequisites are the same as before. We will make use of the token service we created in the previous recipe, Implementing Lagom services.

How to do it…

For this recipe, we need to perform the following steps:

  1. First, create a package named com.packt.chapter11.token.impl inside...
