Selenium is one of most widely used popular tool for automation testing. we can use selenium to read email body attachment or to send the email with help of Java Mail Jars.
Sending email through Java with SSL / TLS authentication
The JavaMail API defines classes which represent the components of a mail system. JavaMail does not implement an email server, instead it allows you to access an email server using a Java API. In order to test the code presented, you must have access to an email server. While the JavaMail API specification does not mandate support for specific protocols, JavaMail typically includes support for POP3, IMAP, and SMTP.
Prerequisite:
- Have access to an SMTP server. You must know the host name, port number, and security settings for your SMTP server. Web mail providers may offer SMTP access, view your email account settings or help to find further information. Be aware that your username is often your full email address and not just the name that comes before the @ symbol.
- A Java EE IDE and Application Server such as GlassFish or Oracle WebLogic Server. JavaMail can be downloaded as a library in a Java SE application but this tutorial assumes the use of a Java EE application server which would already include JavaMail.
Steps for sending email:
We will cover below 3 scenario to send an email:
1. Send Mail in Java using SMTP without authentication.
2. Send Mail in Java using SMTP with TLS authentication.
3. Send Mail in Java using SMTP with SSL authentication
1.Download java mail jar file which contains the library to send the email.
2.Add jar into your project and if you are working with maven project then you can use dependency.
3. Get the session object – . javax.mail.Session class provides object of session, Session.getDefaultInstance() method and Session.getInstance() method.
// Setup mail server
properties.setProperty("mail.smtp.host", host);
// mail username and password
properties.setProperty("mail.user", "user");
properties.setProperty("mail.password", "password$$");
Compose the message–
javax.mail.Transport class provides method to send the message.
// javax.mail.internet.MimeMessage class is
// mostly used for abstraction.
MimeMessage message = new MimeMessage(session);
// header field of the header.
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject("subject");
message.setText("Hello, aas is sending email ");
Send the message –
Transport.send(message);
1.Send Mail in Java using SMTP without authentication full implementation in java
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class SendEmail {
public static void main(String[] args)
{
// change below lines accordingly
String to = "got@gmail.com";
String from = "akash@gmail.com";
String host = "localhost"; // or IP address
// Get the session object
// Get system properties
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", host);
// Get the default Session object
Session session = Session.getDefaultInstance(properties);
// compose the message
try {
// javax.mail.internet.MimeMessage class
// is mostly used for abstraction.
MimeMessage message = new MimeMessage(session);
// header field of the header.
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject("subject");
message.setText("Hello, aas is sending email ");
// Send message
Transport.send(message);
System.out.println("Yo it has been sent..");
}
catch (MessagingException mex) {
mex.printStackTrace();
}
}
}
The program is simple to understand and works well, but in real life most of the SMTP servers use some sort of authentication such as TLS or SSL authentication. So, we will now see how to create Session object for these authentication protocols.
For TLS & SSL you can to know port in which the mail server running those service.
2. Following is the Send Mail in Java using SMTP with TLS authentication full implementation :
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class SendMail {
public static void main(String[] args) {
// change accordingly
final String username = "username@gmail.com";
// change accordingly
final String password = "password";
// or IP address
final String host = "localhost";
// Get system properties
Properties props = new Properties();
// enable authentication
props.put("mail.smtp.auth", host);
// enable STARTTLS
props.put("mail.smtp.starttls.enable", "true");
// Setup mail server
props.put("mail.smtp.host", "smtp.gmail.com");
// TLS Port
props.put("mail.smtp.port", "587");
// creating Session instance referenced to
// Authenticator object to pass in
// Session.getInstance argument
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
//override the getPasswordAuthentication method
protected PasswordAuthentication
getPasswordAuthentication() {
return new PasswordAuthentication(username,
password);
}
});
try {
// compose the message
// javax.mail.internet.MimeMessage class is
// mostly used for abstraction.
Message message = new MimeMessage(session);
// header field of the header.
message.setFrom(new InternetAddress("from-email@gmail.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("to-email@gmail.com"));
message.setSubject("hello");
message.setText("Yo it has been sent");
Transport.send(message); //send Message
System.out.println("Done");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
}
3. Following is the Send Mail in Java using SMTP with SSL authentication full implementation :

// or IP address
String host = "localhost";
// mail id
final String username = "username@gmail.com"
// correct password for gmail id
final String password = "mypassword";
System.out.println("TLSEmail Start");
// Get the session object
// Get system properties
Properties properties = System.getProperties();
// Setup mail server
properties.setProperty("mail.smtp.host", host);
// SSL Port
properties.put("mail.smtp.port", "465");
// enable authentication

}
});
}
//compose the message
try {

MimeMessage message = new MimeMessage(session);
// header field of the header.
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,

// Send message
Transport.send(message);
System.out.println("Yo it has been sent..");
}

}
