Generate random emails

Question

Can you please help me?? How can I generate random emails using Selenium with Java? ?

I was looking here in stackoverflow but I haven't found the answer to this. Ive tried with this but it didnt help

If you just want to generate emails, selenium is not needed. Could do you add your code so far? — cralfaro, Aug 23 '17 at 13:47

You need random string generator. This answer I stole from here.

protected String getSaltString() {
        String SALTCHARS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
        StringBuilder salt = new StringBuilder();
        Random rnd = new Random();
        while (salt.length() < 10) { // length of the random string.
            int index = (int) (rnd.nextFloat() * SALTCHARS.length());
            salt.append(SALTCHARS.charAt(index));
        }
        String saltStr = salt.toString();
        return saltStr;

    }

Call it as getSaltString()+"@gmail.com" in you code

An email shouldn't start with a digit, no? – android developer Aug 17 '19 at 20:24

Try this method

/**
 * @author mbn
 * @Date 05/10/2018
 * @Purpose This method will generate a random integer
 * @param length --> the length of the random emails we want to generate
 * @return method will return a random email String
 */
public static String generateRandomEmail(int length) {
    log.info("Generating a Random email String");
    String allowedChars = "abcdefghijklmnopqrstuvwxyz" + "1234567890" + "_-.";
    String email = "";
    String temp = RandomStringUtils.random(length, allowedChars);
    email = temp.substring(0, temp.length() - 9) + "@testdata.com";
    return email;
}

You can also use MockNeat. A simple example the library would be:

String email = mock.emails().val();
// Possible Output: icedvida@yahoo.com

Or if you want to generate emails from specific domains:

String corpEmail = mock.emails().domain("startup.io").val();
// Possible Output: tiptoplunge@startup.io

This is my solution for the random email generator.

 //randomestring() will return string of 8 chars

  import org.apache.commons.lang3.RandomStringUtils;

  public String randomestring()
  {
    String generatedstring=RandomStringUtils.randomAlphabetic(8);
    return(generatedstring);
   }


  //Usage
   String email=randomestring()+"@gmail.com";

 //For Random Number generation 
////randomeNum() will return string of 4 digits

   public static String randomeNum() {
        String generatedString2 = RandomStringUtils.randomNumeric(4);
        return (generatedString2);
     }

You can create a method for generating the unique id

 public static String getUniqueId() {
            return String.format("%s_%s", UUID.randomUUID().toString().substring(0, 5), System.currentTimeMillis() / 1000);
        }

And then use this method with hostname which you need

 public static String generateMailinatorEmail() {
        return String.format("%s@%s", getUniqueId(), "yourHostName.com");
    }

Another solution:

Add dependency for javafaker.Faker https://github.com/DiUS/java-faker

import com.github.javafaker.Faker;

public static String randomEmail() {
      Faker faker = new Faker();
      return faker.internet().emailAddress();
    }

If you don't mind adding a library, Generex is great for test data. https://github.com/mifmif/Generex

Add this to your pom.xml if you are using maven, otherwise check the link above for other options.

    <dependency>
        <groupId>com.github.mifmif</groupId>
        <artifactId>generex</artifactId>
        <version>1.0.2</version>
    </dependency>

Then:

// we have to escape @ for some reason, otherwise we get StackOverflowError
String regex = "\\w{10}\\@gmail\\.com"
driver.findElement(By.id("emailAddressInput"))
           .sendText(new Generex(regex).random());

It uses a regular expression to specify the format for the random generation. The regex above is generate 10 random word characters, append @gmail.com. If you want a longer username, change the number 10.

If you want to generate a random mobile number for say, Zimbabwe (where I live):

String regex = "2637(1|3|7|8)\\d{7}";

This library has saved me so many hours.

Executing your email regex as an example (which lacks a semi-colon at the end of first line btw), it causes a StackOverflowError. I was able to solve it by adding a \\ (double backslash) before the @ — paulo.bing, Feb 08 '19 at 12:12

Here's a way to do it in Kotlin:

object EmailGenerator {
    private const val ALLOWED_CHARS = "abcdefghijklmnopqrstuvwxyz" + "1234567890" + "_-."

    @Suppress("SpellCheckingInspection")
    fun generateRandomEmail(@IntRange(from = 1) localEmailLength: Int, host: String = "gmail.com"): String {
        val firstLetter = RandomStringUtils.random(1, 'a'.toInt(), 'z'.toInt(), false, false)
        val temp = if (localEmailLength == 1) "" else RandomStringUtils.random(localEmailLength - 1, ALLOWED_CHARS)
        return "$firstLetter$temp@$host"
    }
}

Gradle file :

// https://mvnrepository.com/artifact/org.apache.commons/commons-lang3
implementation 'org.apache.commons:commons-lang3:3.7'
