java - JUnit 规则和 cdi

Question

我不太熟悉 cdi 或 JUnit 规则(事实上我刚刚发现它们)，但我尝试使用 embedded-ldap-junit 测试我的 ldap api库(基于 UnboundID LDAP SDK )遵循 this post 。我准确地说，我的 api 不是基于 UnboundId LDAP SDK 的!

这是我的代码:

@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"));
    }
}

当我尝试运行它时，出现以下异常:

<小时/>

我尝试使用embeddedLdapRule访问级别修饰符(私有(private)、/ protected /公共(public))，但没有成功。你能向我解释一下我做错了什么吗？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

所以解决方案是:

@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"));
    }
}
