JUnit Rule和cdi

Question

我对cdi或or JUnit Rule（实际上我刚刚发现它们）并不十分熟悉，但我尝试使用embedded-ldap-junit库（基于UnboundID LDAP SDK）在this post之后测试我的ldap api。我确定我的api不是基于UnboundId LDAP SDK！

这里是我的代码：

@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")); 
    } 
} 

当我尝试运行它，我有以下异常：

我试图在embeddedLdapRule访问级别修饰符玩（私人，/保护/公共）没有成功。你能向我解释我做错了什么吗？非常感谢 ！

我终于找到了答案：CdiUnit test with Junit @Rule is impossible because of a public private field paradox

因此，解决办法是：

@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")); 
    } 
}
