In this section, you will learn how Arquillian can be used to test microservices created with Swarm. As you learned in previous chapters, Swarm builds a runtime containing only fractions needed by a given service, starts it, and then deploys an archive on it, creating the microservice.

First of all, we have to provide all the necessary dependencies:
