bład :

Na pewno zapomniałeś dodać klas Person, AbstractManager i pliku persistence.xml. Powinno być jakoś tak:

@Deployment
public static Archive<?> deployService() {
	return ShrinkWrap.create(WebArchive.class)
                .addClasses(PersonManager.class, AbstractManager.class, Person.class)
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml")
                .addAsResource("META-INF/persistence.xml")
                ;
}

Musisz też dodać odpowiednie zależności do pom.xml i ustawienia w arquilian.xml

nie wiem dlaczego wystepuje nullpointer

Ta linia wyrzuca bład NullPoiterException

masz jakis pomysł dlaczego tak jest?

Pewnie PersonManager się nie wstrzykuje. Jakiego serwera aplikacyjnego używasz, i w jakim trybie deployujesz (remote/embeded/managed) ? Ja preferuję remote.

To wystarczy?

Przekopiuje ci po prostu ustawienia jednego z moich programów:

aplikacja/src/test/resources/arquillian.xml :

<?xml version="1.0"?>
<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns="http://jboss.org/schema/arquillian"
            xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
    
    <container qualifier="wildfly" default="true" >
        <configuration>
            <property name="managementAddress">127.0.0.1</property>
            <property name="managementPort">9990</property>
            <property name="username">admin</property>
            <property name="password">mypassword</property>
        </configuration>
    </container>   
    
</arquillian>

dodać do pom.xml:
