JUnit 规则和 cdi

Question

我不太熟悉 cdi 或 JUnit Rule（事实上我刚刚发现它们），但我尝试使用 embedded-ldap-junit 库（基于 UnboundID LDAP SDK）测试我的 ldap api，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：

我尝试使用 EmbeddedLdapRule 访问级别修饰符（私有、/受保护/公共）但没有成功。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

所以解决办法是：

@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"));
    }
}
