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
getSaltString()+"@gmail.com"在你的代码中调用它

You can also use MockNeat. A simple example the library would be:
您也可以使用MockNeat。图书馆的一个简单例子是：
String email = mock.emails().val();
// Possible Output: [email protected]
Or if you want to generate emails from specific domains:
或者，如果您想从特定域生成电子邮件：
String corpEmail = mock.emails().domain("startup.io").val();
// Possible Output: [email protected]

This is my solution for the random email generator.
这是我对随机电子邮件生成器的解决方案。
//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);
}

Here's a way to do it in Kotlin:
这是在 Kotlin 中实现的方法：
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"
}
}

If you don't mind adding a library, Generex is great for test data. https://github.com/mifmif/Generex
如果您不介意添加库，Geneex 非常适合测试数据。 https://github.com/mifmif/Generex
Add this to your pom.xml if you are using maven, otherwise check the link above for other options.
如果您使用的是 maven，请将其添加到您的 pom.xml 中，否则请查看上面的链接以获取其他选项。
<dependency>
<groupId>com.github.mifmif</groupId>
<artifactId>generex</artifactId>
<version>1.0.2</version>
</dependency>
Then:
然后：
// 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.
它使用正则表达式来指定随机生成的格式。上面的正则表达式是生成 10 个随机单词字符，附加 @gmail.com。如果您想要更长的用户名，请更改数字 10。
If you want to generate a random mobile number for say, Zimbabwe (where I live):
如果你想生成一个随机的手机号码，比如津巴布韦（我住的地方）：
String regex = "2637(1|3|7|8)\d{7}";
This library has saved me so many hours.
这个图书馆为我节省了很多时间。

Try this method
试试这个方法
/**
* @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;
}
