This is a VerticleFactory
implementation which deploys a verticle given a service name and load it from a Maven
repository.
The documentation is available here, or on the the vert.x web site.
First you need to build the project from Maven:
mvn clean package
Once done, you can run the tests from your IDE.
Notice that the tests are using "projects" (actually, artifacts generated by theses projects) built during the Maven build.
