My stack:
JBoss Wildfly 10 server
Ubuntu 16.04
Java 8
Postgres 9.5.6
Hibernate 5
I am having problems trying to get my JUnit test to work. The unit tests were created by JBoss and they are used to test if Hibernate is working properly. I got their hibernate5 quickstart tutorial to work, and it was using an H2 database. Now I'm trying to use some of their code (datasource.xml and persistence.xml) for my personal project, and I'm using a Postgres database with Hibernate JPA. I got the following exception when I tried to run the unit test:
Code:

I tried to configure my standalone.xml using this StackOverflow post
http://stackoverflow.com/questions/39281314/wflyctl0412-required-services-that-are-not-installed. Here's what my standalone.xml datasource looks like:
