Validating the content of email templates received using test automation

Question

I have multiple email templates in my regression pack and tests include validating the content of email received (examples: Email address, name etc.).

Does anyone have an idea on how to automate the process of validating the content of email templates ?

Answer 1

Yes, you can validate the content of email.

If you need to write selenium script which will trigger the email, then you can use javax mail API for fetching the email from inbox.

Following is code for fetching the email from inbox.

private Message getEmail(String emailID, String password, String subjectToBeSearched) throws Exception {
    Properties props = System.getProperties();
    props.setProperty("mail.store.protocol", "imaps");

    Session session = Session.getDefaultInstance(props, null);
    Store store = session.getStore("imaps");
    store.connect("imap.gmail.com", emailID, password);

    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_WRITE);

    Message[] messages = null;
    boolean mailFound = false;
    Message email = null;

    for (int i = 0; i < 30; i++) {
        messages = folder.search(new SubjectTerm(subjectToBeSearched), folder.getMessages());
        if (messages.length == 0) {
            Thread.sleep(10000);
        }
    }

    for (Message mail : messages) {
        if (!mail.isSet(Flags.Flag.SEEN)) {
            email = mail;
            mailFound = true;
        }
    }

    if (!mailFound) {
        throw new Exception("Could not found Email");
    }

    return email;
}

Above function will return you the message, then you can perform operations on message object, for example reading mail subject you can use following code.

email.getSubject();

Following code to get details of FROM

email.getFrom()

And many more functions.
