单元测试用例中的Null@autowired beans

Question

@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration(locations = "classpath*:business-context-test.xml")
public class SMSGatewayTest {

    @Autowired
    @Qualifier("mySMSImpl")
    private ISMSGateway smsGateway;

        @Test
        public void testSendTextMessage() throws Exception {
          smsGateway.sendText(new TextMessage("TEST")); 
          //  ^___________ this is null, even though I have set ContextConfiguration 
        }

}

spring管理bean

package com.myproject.business;

@Component("mySMSImpl")
public class MySMSImpl implements ISMSGateway {

    @Override
    public Boolean sendText(TextMessage textMessage ) throws VtsException {
          //do something
    }

}

我看到了许多问题，所有问题都给出了我已经在代码中包含的答案。谁能告诉我我错过了什么。我正在使用IntelliJ14来运行我的测试用例。

Answer 1

您的代码如下所示：

@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration(locations = "classpath*:business-context-test.xml")
public class SMSGatewayTest {
   ..
   ..
}

你真的想使用MockitoJUnitRunner，因为我在课堂上看不到更多的嘲笑。

请尝试用like运行JUnit

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath*:business-context-test.xml")
public class SMSGatewayTest {
   ..
   ..
}
