Question

我试图模拟发送电子邮件功能但遇到以下错误。我做错了什么或遗失了什么。

@Mock
private MailServiceImpl mailService;

@Mock
private JavaMailSenderImpl javaMailSender;


@Before
public  void setUp() {
    MockitoAnnotations.initMocks(this);
    mailService=new MailServiceImpl(javaMailSender);

}


@Test
public void testSendEmail() {

    try {
        doNothing().when(mailService).sendMail(getEmailProperties());
        mailService.sendMail(getEmailProperties()); 
        verify(mailService,times(1)).sendMail(getEmailProperties());
    } catch (Exception e) {
        Assert.fail(e.getMessage());
    }

}

public EmailProperties getEmailProperties() {

    EmailProperties emailProperties = new EmailProperties();

    emailProperties.setFromAddress("from@Test.com");
    emailProperties.setToAddress("To@Test.com");
    emailProperties.setEmailBody("Test");
    emailProperties.setSubject("Test email");
    emailProperties.setAttachment((File) null);
    emailProperties.setMessageType(1);

    return emailProperties;
  }

错误： java.lang.AssertionError：传递给when（）不是模拟的参数！正确存根的示例： doThrow（new RuntimeException（））。when（mock）.someMethod（）; 在org.junit.Assert.fail（Assert.java:88）在com.xx.xx.xx.mail.MailServiceTest.testSendEmail（MailServiceTest.java:52） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62）在

Answer 1

错误消息试图说Mockito.when()方法只接受模拟/间谍对象。

您在mailService方法中使用when，这是错误的，因为它既没有被嘲弄也没有被抄袭。

mailService=new MailServiceImpl(javaMailSender);

由于未提供测试代码，因此无法详细说明。

但你可以尝试更换
mailService=new MailServiceImpl(javaMailSender); 同 mailService=Mockito.spy(new MailServiceImpl(javaMailSender));

这会使你的mailService成为mockito接受的东西。

Answer 2

删除doNothing（）。when（mailService）.sendMail（getEmailProperties（））;解决了这个问题。不确定导致此问题的原因
