| - | ====== subethamail - a simple way to test mail sender ====== | ||
| - | ===== Problem ===== | ||
| - | 為了要驗證程式所寄出的人或訊息是否正確，我們可以寫一些mock程式去攔截收到的內容；也可以透過java mail去接收者的信箱中把內容撈出來比對。這些方法寫起來會比較花時間，如果能透過既有的mail server，可能就會容易多了。 | ||
| - | ===== How to? ===== | ||
| - | 原先Albert有找到一套叫[[https://nilhcem.github.io/FakeSMTP/|FakeSMTP]]的library，經過試驗發現它並不容易被拿進來寫UnitTest。因此直接使用它所相依的library subethamail，非常簡單就可以讓你去確認寄送者、接收者與信件內容: | ||
| - | <code java> | ||
| - | private SMTPServer server; | ||
| - | private List<String> toList = new ArrayList<>(); | ||
| - | private String testContent; | ||
| - | |||
| - | @Before | ||
| - | public void setUp() throws Exception { | ||
| - | try { | ||
| - | server = new SMTPServer(new SimpleMessageListenerAdapter(new SimpleMessageListener() { | ||
| - | |||
| - | @Override | ||
| - | public void deliver(String from, String to, InputStream content) | ||
| - | throws TooMuchDataException, IOException { | ||
| - | logger.info("deliver {}", from); | ||
| - | logger.info("deliver {}", to); | ||
| - | toList.add(to); | ||
| - | testContent = IOUtils.toString(content); | ||
| - | } | ||
| - | |||
| - | @Override | ||
| - | public boolean accept(String from, String to) { | ||
| - | logger.info("accept {}", from); | ||
| - | logger.info("accept {}", to); | ||
| - | return true; | ||
| - | } | ||
| - | })); | ||
| - | server.setBindAddress(InetAddress.getByName("0.0.0.0")); | ||
| - | server.setPort(25); | ||
| - | |||
| - | server.start(); | ||
| - | System.out.println("Start SMTP Server"); | ||
| - | } catch (Exception e) { | ||
| - | // Ignore | ||
| - | } | ||
| - | |||
| - | } | ||
| - | |||
| - | @After | ||
| - | public void tearDown() throws Exception { | ||
| - | if (server !=null) | ||
| - | server.stop(); | ||
| - | } | ||
| - | |||
| - | @Test | ||
| - | public void test() { | ||
| - | // do something | ||
| - | |||
| - | assertEquals(2, toList.size()); | ||
| - | assertTrue(toList.contains("test1@tonylin.org.tw")); | ||
| - | assertTrue(toList.contains("test2@tonylin.org.tw")); | ||
| - | assertTrue(testContent.contains("test message")); | ||
