Mockito ArgumentCaptor正在返回Null

我正在尝试使用Mockito ArgumentCaptor在我的方法中获取mime消息。当我获取捕获对象时,其值为null。我试图调试它,但是Mockito用增强器包装它,所以我看不到内容。这适用于我方法中的对象。有没有人有想法?

这是我的样本测试。 msg不为null,但该方法在返回null之后调用。

@Test
public void testSendTemplatedMail() throws MessagingException, IOException {
    Context ctx = new Context();
    ctx.setVariable("name", "John Doe");
    ctx.setVariable("subscriptionDate", new Date());
    ctx.setVariable("hobbies", Arrays.asList("Cinema", "Sports", "Music"));
    String templateName = "testEmailTemplateWithoutImage";
    when(mailSenderMock.createMimeMessage()).thenReturn(mock(MimeMessage.class));

    try {
        mailUtils.sendTemplatedMail("John Doe", "john.doe@bbc.com",
                        "no-reply@leanvelocitylabs.com", "Hello",
                        templateName, ctx);
    } catch (Exception e) {
        e.printStackTrace();
        throw e;
    }

    ArgumentCaptor<MimeMessage> msg = ArgumentCaptor.forClass(MimeMessage.class);

    verify(mailSenderMock, times(1)).createMimeMessage();
    verify(mailSenderMock, times(1)).send(msg.capture());
    verifyNoMoreInteractions(mailSenderMock);

    System.out.println("Sample msg subject = " + msg);
    System.out.println("Sample msg ctype = " + msg.getValue().getContentType());
    System.out.println("Sample msg to = " + msg.getValue().getAllRecipients());
    System.out.println("Sample msg sender = " + msg.getValue().getSender());
    System.out.println("Sample msg from = " + msg.getValue().getFrom());
    System.out.println("Sample msg content = " + msg.getValue().getContent());




    // assertEquals("accountAlmostDone", mv.getViewName());
    // assertEquals("NA", mv.getModel().get("activationCode"));
}

你已经存根createMimeMessage来返回模拟。据推测,这个模拟是传递给send的东西;所以你的论证捕获者只是捕获模拟。模拟(getContentType()和其他)上的每个方法都只返回null,因为你还没有存根它们。
