E-mail Distribution of Test Results Obtained from Selenium + TestNG

by Nataliia Vasylyna | February 24, 2011 12:20 pm

If you have to run a bunch of automated tests[1] using Selenium + TestNG, the results of running the tests can be easily sent to all interested parties automatically.

It is very convenient in terms of informing participants about the current status of the project’s main functionality. You can also make a small package of automated tests for the product version of your project and run it several times a day. In this case, you will learn about problems encountered one of the first and not get angry letter from a customer.

Test Results[2]

It will be sufficient to simply view the reports in your email client. Running of the automated tests can be configured using Scheduler. This I will explain later.

The results run the automated tests are stored in the file /test-output/emailable-report.html. This report is designed specifically for e-mailing to all parties involved.

Also the report can include screenshots of all failed tests. In my opinion, a visual representation of the result makes it easier to understand the reason of test failure. Opening the screenshot, you can immediately see whether it is a software bug or is it error in test data.

The screenshots in this example, during the run automated tests are placed in the folder

/ test-output/screenshots and have a pretty informative name.

For example, DailyPack.Administrator_Department.Admin_Department_5_Clients_

DailyPack.Administrator_Department – package name

Admin_Department_5_Clients_Sorting – class name

testDeleteClients – method name

07_01_2009_17_58 – a time when a screenshot was obtained

To send the results I’m using JavaMail 1.4.2[3]. This set of classes for working with the mail system.

import java.text.SimpleDateFormat;
import java.util.*;
import java.io.*;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;

      // Получаем текущую дату

      Calendar c = Calendar.getInstance();

        SimpleDateFormat sdf = new SimpleDateFormat("MM.dd.yyyy kk:mm");

        // от кого будет письмо

        String from = "tester@qa-testlab.com";

        // получатель 1

        String to1 = "tester2@qa-testlab.com";

        // получатель 2

        String to2 = "developer@qa-testlab.com";

// получатель 3

        String to3 = "pm@qa-testlab.com";

// результаты прогона тестов для какого проекта

        String project = "Book Shop";

        // путь к отчету emailable-report.html

        String path2 = "C:\\B2B_Pack\\test-output\\screenshots";


      from, to1, to2, to3,

       "Test Results for " + project + " " + sdf.format(c.getTime()), path1, path2);


public void sendEmail(

    String aFromEmailAddr, String aToEmailAddr, String aToEmailAddr2, String aToEmailAddr3,

    String aSubject, String attach, String screenpath

  ) throws IOException{

Session session = Session.getDefaultInstance( fMailServerConfig, null );

    MimeMessage message = new MimeMessage( session );

try {

      // добавляем получателя 1


        Message.RecipientType.TO, new InternetAddress(aToEmailAddr)


     // добавляем получателя 2


      Message.RecipientType.TO, new InternetAddress(aToEmailAddr2)

Transport.send( message );

      System.out.println("Mail was sent to " + aToEmailAddr + ", " + aToEmailAddr2 + ", " + aToEmailAddr3);
catch (MessagingException ex){
System.err.println("Cannot send email. " + ex);

public static void refreshConfig() {

fMailServerConfig.load( input );

    catch ( IOException ex ){

    finally {

System.err.println( "Cannot close mail server properties file." );
