You can create a custom keyword as follow

```auto
public class RandomEmail {

```

```auto
    @Keyword

```

```auto
    public String getEmail(String suffix,String prefix){

```

```auto
        int randomNo = (int)(Math.random() * 1000);

```

```auto
        return suffix + randomNo + "@" + prefix; 

```

```auto
    }

```

```auto

}

```

And then use in the test as follow
