test-persistence.xml jta-datasource or non-jta-datasource required

[pdstat]

In the "Testing Java Peristence" guide it says

Alternatively, you can skip the DataSource configuration and simply include the database connection information directly in test-persistence.xml using standard database connection properties:

However if for example I create a test-peristence.xml like so

<persistence-unit name="primary">
	<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
	<!--  <jta-data-source>jdbc/derby</jta-data-source> -->
	<properties>
		<!-- Common properties -->
		<property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.EmbeddedDriver" />
		<property name="javax.persistence.jdbc.url" value="jdbc:derby:memory:test-jpa;create=true" />
		<property name="javax.persistence.jdbc.user" value="APP" />
		<property name="javax.persistence.jdbc.password" value="APP" />

		<!-- EclipseLink specific properties -->
		<property name="eclipselink.target-database" value="Derby" />
		<property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
		<property name="eclipselink.debug" value="ALL" />
		<property name="eclipselink.weaving" value="static" />
		<property name="eclipselink.logging.level" value="FINEST" />
		<property name="eclipselink.logging.level.sql" value="FINEST" />
		<property name="eclipselink.logging.level.cache" value="FINEST" />
	</properties>
</persistence-unit>

And then try to create a simple deployment for example

@Deployment
public static Archive<?> createDeployment() {
	return ShrinkWrap.create(WebArchive.class, "test.war")
			.addClass(User.class)
			.addAsResource("test-persistence.xml", "persistence.xml")
			.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
}

I get the following stack trace

If I then create a datasource in Weblogic and specify it in the jta-data-source I don't get this issue.

[neormx]

I confirm the error reported by @PaulStat. Code only works by using the jta-data-source property; otherwise I got the same NPE he says.

I'm using the latest version reported on arquillian module's page: 1.0.0.Alpha7, however I can see int this site's releases page that there are newer versions but no commits since 2017. Is this project still alive @bartoszmajsak?
