其中 GreenMail 是最适合做单元测试的,它本身并不会发送邮件,但支持SMTP, POP3, IMAP。发布的时间也很长了,不过知道的人并不多。如果做发送邮件代码的单元测试,不想走邮件服务器,也不想mock的话,GreenMail 是个很好的选择。

目前版本:greenmail-1.3.1b.jar
Roadmap显示在1.4+版本中将会用 SubEthaSMTP 代替目前GreenMail自身的SMTP代码。
private static void testSMTPCode() throws Exception { GreenMail greenMail = new GreenMail(); greenMail.start(); // Sending GreenMailUtil.sendTextEmailTest("[email protected]", "[email protected]", "subject", "body"); // Retrieving String msg = GreenMailUtil.getBody(greenMail.getReceivedMessages()[0]); System.out.println(msg); greenMail.stop(); }
private static void testSMTPSCode() throws Exception { GreenMail greenMail = new GreenMail(); greenMail.start(); // Sending GreenMailUtil.sendTextEmailSecureTest("[email protected]", "[email protected]", "subject", "body"); // Retrieving String msg = GreenMailUtil.getBody(greenMail.getReceivedMessages()[0]); System.out.println(msg); greenMail.stop(); }
private static void testSpecialPort() throws Exception { ServerSetup ss = new ServerSetup(3025, null, "smtp"); GreenMail greenMail = new GreenMail(ss); greenMail.start(); GreenMailUtil.sendTextEmail("[email protected]", "[email protected]", "subject", "body", ss); greenMail.stop(); }
