How to automate an email?

Question

Hey, i am working in a project, where while submitting the task, it automatically generates a mail and send to the user.

I have to validate the mail content as well the UI , Can you please suggest me some tools are methods to automate emails?

Answer 1

We usually log in via POP3 to the server and fetch an email and validate it. If its microsoft exchange, you will have to work with exchange API and validate the response.

Java code sample to fetch an email using POP3.

 

import java.util.Properties;

 

import javax.mail.Folder;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.NoSuchProviderException;

import javax.mail.Session;

import javax.mail.Store;

 

public class ValidateEmails{

 

   public static void get(String host, String storeType, String user,

      String password) 

   {

      try {

 

      //create properties field

      Properties properties = new Properties();

 

      properties.put("mail.pop3.host", host);

      properties.put("mail.pop3.port", "995");

      properties.put("mail.pop3.starttls.enable", "true");

      Session emailSession = Session.getDefaultInstance(properties);

  

      //create the POP3 store object and connect with the pop server

      Store store = emailSession.getStore("pop3s");

 

      store.connect(host, user, password);

 

      //create the folder object and open it

      Folder emailFolder = store.getFolder("INBOX");

      emailFolder.open(Folder.READ_ONLY);

 

      // retrieve the messages from the folder in an array and print it

      Message[] messages = emailFolder.getMessages();

      System.out.println("messages.length---" + messages.length);

 

      for (int i = 0, n = messages.length; i < n; i++) {

         Message message = messages[i];

         System.out.println("---------------------------------");

         System.out.println("Email Number " + (i + 1));

         System.out.println("Subject: " + message.getSubject());

         System.out.println("From: " + message.getFrom()[0]);

         System.out.println("Text: " + message.getContent().toString());

 

      }

 

      //close the store and folder objects

      emailFolder.close(false);

      store.close();

 

      } catch (NoSuchProviderException e) {

         e.printStackTrace();

      } catch (MessagingException e) {

         e.printStackTrace();

      } catch (Exception e) {

         e.printStackTrace();

      }

   }

 

   public static void main(String[] args) {

 

      String host = "pop.gmail.com";// change accordingly

      String mailStoreType = "pop3";

      String username = "[email protected]";// change accordingly

      String password = "password"; // change accordingly

 

      get(host, mailStoreType, username, password);

 

   }

 

}

 

Hope that helps!
