Selenium Email external list

Question

I have my selenium test send an email whenever there is an error, this is hard coded into my test however I am looking to see if it is possible to call it from an external file so I can just edit the Email file instead of having to go into the code and change it.

The way i'm getting it to email is

try {

}
catch (Exception e) {
    e.printStackTrace();
    new SendMail("senderemail","reciveremail",e); } 
}

Which calls it directly from:

public SendMail(String fromMail,String tomail, Exception e ) {
    Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");
    Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("xxxxxxx","xxxxxx");

Question: How can I get my selenium to get a list from an external file of emails to send them out?

Edit: Updated code of what finally works.

String fileName = "/Users/cdolan/Desktop/liness.txt";
String Email = "";

try(BufferedReader br = new BufferedReader(new FileReader(fileName)) {  
    while ((Email = br.readLine()) !=null) {
        <Test code here goes here>
    }
}
catch(Exception e) {
    e.printStackTrace();
    new SendMail("email123@gmail.com",Email,e); }
}

Answer 1

Before your SendMail class, you can include a file upload method that will upload a file, then you can read the lines of the file and pass those emails into the SendMail method in a loop:

Each email address would need to be on a new line with no blank lines.

String fileName = "c://lines.txt";

    try (BufferedReader br = new BufferedReader(new FileReader(fileName))) {

        String line;
        while ((line = br.readLine()) != null) {
            //sends email to each line in the text file
            System.out.println("text line: " + line);
            new SendEmail("senderEmail", line);
        }

    } catch (IOException e) {
        e.printStackTrace();
    }

Not sure why you want to send emails from your Selenium test code, but most companies let test-results be handled by a continuous integration server. Instead of writing your own test-error handling let the CI do this.

All CI-servers have options to send out e-mails to developers and testers when a test is failing. But it also has other means of reporting, like #Slack integration or sms. The CI-server can even send emails to the developers who broke the build. This by starting a test run for each commit/checkin.

Here some CI-servers for on premise

Or some in the cloud
