如何随机化 CI 服务器的绿邮件中的端口

Question

使用JUnit和Greenmail，我希望实现Greenmail使用的随机端口，而不是默认端口或带有偏移量的端口。 为此，我尝试使用 ServerSocket(0( 获取一个随机端口，并且绿邮件的启动按设计工作。 但是当我尝试在测试期间发送邮件时，我收到异常"无法连接到端口 3025"，这是绿邮件默认值。

ServerSocket ssSMTP = new ServerSocket(0);
ServerSocket ssIMAP = new ServerSocket(0);

ssSMTP.close();
ssIMAP.close();
ServerSetup smtpSetup = new ServerSetup(randomPortSMTP, null, ServerSetup.PROTOCOL_SMTP);
ServerSetup imapSetup = new ServerSetup(randomPortIMAP, null, ServerSetup.PROTOCOL_IMAP);
greenMailSMTPIMAP = new GreenMail(new ServerSetup[]{smtpSetup,imapSetup});
greenMailSMTPIMAP.start();
}
@After
public void tearDown()
{
greenMailSMTPIMAP.stop();
}
@Test
public void testSend() throws MessagingException
{
GreenMailUtil.sendTextEmailTest("[e-mail]", "[e-mail]",
"some subject", "some body"); // --- Place your sending code here instead

}

"subject", "body"); // ...or use the default messages
assertEquals(2, greenMailSMTPIMAP.getReceivedMessages().length); // // --- Place your POP3 or IMAP retrieve code here
}
private MimeMessage createMimeMessage()

return GreenMailUtil.createTextEmail("[e-mail]", "[e-mail]", "subject", "body", greenMailSMTPIMAP.getImap().getServerSetup());

只需将服务器安装程序传递给方法 GreenMailUtil.sendTextEmail(...，ServerSetup( 并且不要使用标准的*测试方法。

@Test
public void testSend() throws MessagingException
{
GreenMailUtil.sendTextEmail("[e-mail]", "[e-mail]",
"some subject", "some body", greenMail.getSmtp().getServerSetup()); // --- Place your sending code here instead
assertEquals("some body", GreenMailUtil.getBody(greenMail.getReceivedMessages()[0]));
}
