How do I test the JavaMailSender of Spring
提问by Jordi P.S.
I have a service that has injected the JavaMailSender. My service configures it and sends a mail. I'd like to intercept the raw mail to ensure the information is the correct. I'd like to do that in a JUnit.
我有一个注入 JavaMailSender 的服务。我的服务配置它并发送邮件。我想截取原始邮件以确保信息正确。我想在 JUnit 中做到这一点。
How would you guys do that?
你们会怎么做？
@Service
public class MyServiceImpl {
@Autowired
private JavaMailSender _mailSender;
public void sendMail(String to, String body, String subject){
...
_mailSender.something
...
}
}

I've done it using GreenMail. Take a look at my blog post about itwhere you'll also find a working example.
我已经使用GreenMail完成了。看看我关于它的博客文章，在那里你还可以找到一个工作示例。

You can use a test SMTP server, like Dumbster. See the example below:
您可以使用测试 SMTP 服务器，例如Dumbster。请参阅以下示例：
@Test
public void sendSimpleEmailWithCC() {
// Runs a Dumbster simple SMTP server - default config
SimpleSmtpServer server = SimpleSmtpServer.start();
String from = "[email protected]";
String to = "[email protected]";
String messageText = "Good message";
String title = "Test message";
String cc = "[email protected]";
Assert.assertTrue(mailSender
.sendEmail(from, to, cc, title, messageText));
server.stop();
Assert.assertTrue(server.getReceivedEmailSize() == 1);
Iterator emailIter = server.getReceivedEmail();
SmtpMessage email = (SmtpMessage) emailIter.next();
Assert.assertTrue(email.getHeaderValue("From").equals(from));
Assert.assertTrue(email.getHeaderValue("To").equals(to));
Assert.assertTrue(email.getHeaderValue("Cc").equals(cc));
Assert.assertTrue(email.getHeaderValue("Subject")
.equals("Test message"));
Assert.assertTrue(email.getBody().equals(messageText));
}

If your goal is to use just Junit/Mockito and test how MimeMessage was formed before sending then the configuration below should be sufficient:
如果您的目标是仅使用 Junit/Mockito 并在发送之前测试 MimeMessage 的形成方式，那么下面的配置就足够了：
public class EmailServiceTest {
private EmailServiceImpl emailServiceImpl;
private JavaMailSender javaMailSender;
private MimeMessage mimeMessage;
@Before
public void before() {
mimeMessage = new MimeMessage((Session)null);
javaMailSender = mock(JavaMailSender.class);
when(javaMailSender.createMimeMessage()).thenReturn(mimeMessage);
emailServiceImpl = new EmailService(javaMailSender);
}
@Test
public void emailTest() {
String recipient = "[email protected]"
EmailRequest request = new EmailRequest();
request.setRecipient(recipient);
emailServiceImpl.send(request);
assertEquals(recipient, mimeMessage.getRecipients(RecipientType.TO)[0].toString());
}
}
