JUnit Rule and cdi

Question

I'm not really familiar with cdi or or JUnit Rule (in fact I've just discovered them) but I try to test my ldap api with the embedded-ldap-junit library (based on UnboundID LDAP SDK) following this post. I precise that my api is not based on UnboundId LDAP SDK !

Here is my code :

@RunWith(CdiRunner.class)
public class LdapTest extends TestCase {
    public static final Logger LOGGER = LoggerFactory.getLogger(LdapTest.class);
    public static final String DOMAIN_DSN = "dc=my.domain";
    public static final String LDIF_FILE = "agents.ldif";
    public static final String BPM_SCHEMA = "schema.ldif";

    @Inject
    private LDAPManager ldapManager;

    @Rule
    public EmbeddedLdapRule embeddedLdapRule = EmbeddedLdapRuleBuilder.newInstance().usingDomainDsn(DOMAIN_DSN)
        .importingLdifs(LDIF_FILE).withSchema(BPM_SCHEMA).build();

    @Test
    public void getAgent() throws Exception {
        embeddedLdapRule.ldapConnection();
        DirContext dirContext = embeddedLdapRule.dirContext();
        ldapManager.setContext(dirContext);
        assertNotNull(ldapManager.getAgent("123"));
    }
}

When I try to run it, I have the following Exception :

I tried to play on the embeddedLdapRule access level modifiers (private,/ protected / public) with no success. Could you please explain to me what I do wrong ? Thanks a lot !

I've finally found an answer : CdiUnit test with Junit @Rule is impossible because of a public private field paradox

So the solution is :

@RunWith(CdiRunner.class)
public class LdapTest extends TestCase {
    public static final Logger LOGGER =     LoggerFactory.getLogger(LdapTest.class);
    public static final String DOMAIN_DSN = "dc=my.domain";
    public static final String LDIF_FILE = "agents.ldif";
    public static final String BPM_SCHEMA = "schema.ldif";

    @Inject
    private LDAPManager ldapManager;

    private EmbeddedLdapRule embeddedLdapRule = EmbeddedLdapRuleBuilder.newInstance()
        .usingDomainDsn(DOMAIN_DSN)
        .importingLdifs(LDIF_FILE)
        .withSchema(BPM_SCHEMA)
        .build();

    @Rule
    public EmbeddedLdapRule getLdapRule() {
        return embeddedLdapRule;
    }

    @Test
    public void getAgent() throws Exception {
        embeddedLdapRule.ldapConnection();
        DirContext dirContext = embeddedLdapRule.dirContext();
        ldapManager.setContext(dirContext);
        assertNotNull(ldapManager.getAgent("123"));
    }
}
