spring web 业务系统单测使用Jmockit 进行夸层mock

spring业务系统一般使用单例. 多层调用.

例如 A调用B,B调用C.

要测试A的方法,需要夸多层mock C的方法.

使用jmockit的NonStrictExpectations

@Service
public class A {
    @Autowired
    B b;

    public void method() {
        b.method();
    }
}

@Service
public class B {
    @Autowired
    IC c;

    public void method() {
        System.out.println("b=" + c.method());
    }
}

@Service
public class C implements IC {
    @Override
    public Integer method() {
        System.out.println("123");
        return 1;
    }
}

public interface IC {


    public Integer method();


}

@RunWith(SpringJUnit4ClassRunner.class)
@TransactionConfiguration(transactionManager = "kuaipayTransactionManager", defaultRollback = true)
@Transactional
@ContextConfiguration(locations = { "classpath:kuaipay-api-impl-test-application.xml" })
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class,
                         TransactionalTestExecutionListener.class })
public class JmockitTestMock  {


    @Autowired
    A  a;


    // 对接口进行mock,对应dubbo
    @Autowired
    IC ic;


    // 夸层 mock.直接把class给替换了. jmockit的神力
    @Test
    public void testMockit() {


        new <span style="color:#ff0000;">NonStrictExpectations</span>(ic) {
            {
                ic.method();
                result = Integer.valueOf(5);
            }
        };
        a.method();
    }
}
