The JUnit test in file "/template.demo/src/test/java/org/onap/policy/template/demo/ControlLoopXacmlGuardTest.java" requires Drools to write to the OperationsHistory DB and XACML PDP to read from it when a Guard policy is executed.

Currently, the test assumes that there is a remote DB exists. Since there is no remote DB available, the test fails. We need to create in-memory DB just for running the test and let Drools and XACML know about it.

Create a new in-memory DB in the JUnit test and specify the access to it in "/eventmanager/src/main/resources/META-INF/persistence.xml".

If the new DB will have a different SQL syntax (than mariadb), then the SQL queries in Guard (/guard/src/main/java/org/onap/policy/guard/PIPEngineGetHistory.java) will need to be updated.
