GreenMail integration test sent email not being relayed to recipient

1.5k Views Asked by At

I'm using greenmail for mail integration test, and came out with below code. The intention is to create 2 fake email servers that act as sender and recipient. However when I ran the code, the test failed because the recipient doesn't receive the email. I've read some sample and faq from 'greenmail' site but can't find the explainations for this behavior. I hope someone could shed some light here.

Below is the test code:

    @Before
public void setUp() {

    // Setup fake smtp server.
    ServerSetup smtpServer = new ServerSetup(Integer.parseInt(smtpPort), smtpHost, smtpProtocol);
    serverA = new GreenMail(smtpServer);
    serverA.start();

    // Setup fake pop3 server.
    ServerSetup pop3Server = new ServerSetup(Integer.parseInt(pop3Port), pop3Host, pop3Protocol);
    serverB = new GreenMail(pop3Server);
    serverB.start();
}

@Test
public void testSendEmailToAvailableMailboxReturnEmail() {
    String senderMail = "[email protected]";
    String senderUsername = "sender1";
    String senderPassword = "password123";

    String receiverMail = "[email protected]";
    String receiverUsername = "receiver1";
    String receiverPassword = "pass567";

    // Set mailbox for sender and receiver
    serverA.setUser(senderMail, senderUsername, senderPassword);
    serverB.setUser(receiverMail, receiverUsername, receiverPassword);

    // Send email from serverA
    String subject = "This is a test subject.";
    String msg = "This is a plain test message.";

    EmailModel emailModel = new EmailModel();
    emailModel.setFrom(senderMail);
    emailModel.setTo(receiverMail);
    emailModel.setSubject(subject);
    emailModel.setBody(msg);
    emailModel.setSentDate(LocalDateTime.now());
    emailModel.setBodyType(EmailModel.EMAIL_TYPE_TEXT);

    // Using javamailsenderimpl to send the mail.
    mailServiceImpl.send(emailModel);

    // Retrieve email from ServerB
    Session session = Session.getDefaultInstance(new Properties(), null);
    try {
        Store store = session.getStore(pop3Protocol);
        store.connect(pop3Host, receiverUsername, receiverPassword);

        Folder inbox = store.getFolder(BatchConstant.MAIL_INBOX);
        inbox.open(Folder.READ_ONLY);
        Message[] messages = inbox.getMessages();
        Assert.assertNotNull(messages);
        Assert.assertEquals(1, messages.length);
        Assert.assertEquals(subject, messages[0].getSubject());
        Assert.assertEquals(msg, String.valueOf(messages[0].getContent()).contains(msg));

    } catch (MessagingException | IOException e) {
        Assert.fail("Should be able to retrive sent mail.");
    }


}

@After
public void tearDown() {
    serverA.stop();
    serverB.stop();
}

It fails at this line:

Assert.assertEquals(1, messages.length);

GreenMail is a sandbox server. It will never route mail to another server.

What you want to do is create a single instance of GreenMail, configured for both SMTP and POP3:

 ServerSetup smtpServerSetup = ...
 ServerSetup pop3ServerSetup = ...
 GreenMail greenMail = new GreenMail(new ServerSetup[]{smtpServerSetup, pop3ServerSetup});
 greenMail.start(); // Starts both smtp and pop3
