selenium-webdriver - 如何为 IMAPFolder.idle 设置超时

Question

我正在用 java 实现 Webdriver 测试，包括检查来自 Gmail 的电子邮件。我的代码在这里：

public static void checkNewEmail(String user, String password, String sender, String subject, ArrayList<String> errorList) throws MessagingException {
    boolean result = false;
    Store store = null;
    Properties props = new Properties();
    props.setProperty("mail.store.protocol", "imaps");
    props.setProperty("mail.imaps.ssl.enable", "true");
    props.setProperty("mail.imaps.port", "993");
    props.setProperty("mail.imaps.timeout", "10000");
    props.setProperty("mail.imaps.connectiontimeout", "10000");

    try {

        Session session = Session.getInstance(props, null);
        store = session.getStore();
        store.connect("imap.gmail.com", user, password);
        Folder inbox = store.getFolder("INBOX");
        inbox.open(Folder.READ_ONLY);
        //add listener
        System.out.println("Listening for New message");
        final Message[] email = new Message[1];
        inbox.addMessageCountListener(new MessageCountAdapter() {
            @Override
            public void messagesAdded(MessageCountEvent ev) {
                Message[] messages = ev.getMessages();
                for (Message msg : messages) {
                    //process emails here
                    System.out.println("New message");
                    email[0] = msg;
                }
            }
        });
        ((IMAPFolder) inbox).idle(true);

        if(email[0] != null) {
            if (email[0].getFrom()[0].toString().contains(sender) && email[0].getSubject().contains(subject)) {
                gm.printSuccessMsg("===PASSED: Correct email arrived.");
                result = true;
            } else {
                System.out.println("Incorrect email arrived.");
                System.out.println(email[0].getFrom()[0].toString());
                System.out.println(email[0].getSubject());
                if (store != null) {
                    store.close();
                }
                checkNewEmail(user, password, sender, subject, errorList);
            }
        }

    } catch (FolderClosedException e) {
        e.printStackTrace();
        if (store != null) {
            store.close();
        }

    } finally {
        if(!result)
            errorList.add("Store email");
        if (store != null) {
            store.close();
            System.out.println("Done");
        }
    }
}
}

调试输出：

当有正确的电子邮件到达时，它可以正确地检查和终止侦听器。但是当没有收到邮件时，它会一直等待，并且超时似乎不起作用，它一直挂在DEBUG IMAP: handleIdle: ignoring socket timeout. 有没有人有同样的问题？我尝试从“setProperty”更改为“put”（使用 int 而不是 string），但它仍然是一样的。

从IMAPFolder 来源：

/*
 * If it was a timeout and no bytes were transferred
 * we ignore it and go back and read again.
 * If the I/O was otherwise interrupted, and no
 * bytes were transferred, we take it as a request
 * to abort the IDLE.
 */

因此设置超时不会导致 IDLE 中止。如果您希望IDLE 中止，请创建另一个线程以等待截止日期并在截止日期到期时调用 close。
