        Scanner kb = new Scanner(System.in);
        System.out.println("enter ur id: ");
        String id = kb.nextLine();
        System.out.println("enter ur pass: ");
        String password = kb.nextLine();
        System.out.println("enter email-id to whom u want to send the mail: ");
        String toId = kb.nextLine();
        System.out.println("enter subject for mail: ");

        //open gamil
        WebDriver driver = new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
        driver.get("https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=https%3A%2F%2Fmail.google.com%2Fmail%2F&ss=1&scc=1&ltmpl=default&ltmplcache=2&hl=en&emr=1&elo=1");
       
        //login to gmail
        driver.findElement(By.id("Email")).sendKeys(id);
        driver.findElement(By.xpath("//input[@id='Passwd']")).sendKeys(password);
        driver.findElement(By.xpath("//input[@type='checkbox']")).click();
        driver.findElement(By.name("signIn")).click();
       
        //click on compose and add the to mail id, and subject
        driver.findElement(By.xpath("//div[text()='COMPOSE']")).click();
        driver.findElement(By.xpath("//form[1]//textarea[1]")).sendKeys(toId);
        driver.findElement(By.xpath("//div[@class='aoD az6']//input[@class='aoT']")).sendKeys(subject);
       
        //wirte the mail body, that mail body is under frame so 1st switch the control to frame then write
        driver.switchTo().frame(driver.findElement(By.xpath("//iframe[@tabindex='1']")));
        driver.findElement(By.xpath("//body[@class='editable LW-avf']")).sendKeys(content);
        driver.switchTo().defaultContent(); // again switch back to main page
       
        //click on attachment
        driver.findElement(By.xpath("//div[@class='a1 aaA aMZ']")).click();
        //use autoit tool to attach a file
        Runtime.getRuntime().exec("C:\\selenium\\AutoIT\\fileUpload.exe");
        Thread.sleep(10000); //wait for 10sec to upload file
       
        //click on send
        driver.findElement(By.xpath("//div[text()='Send']")).click();
        String msg = driver.findElement(By.xpath("//div[contains(text(),'Your message has been sent.')]")).getText();
        String exp = "Your message has been sent. View message";
        Assert.assertEquals(msg, exp);
        System.out.println("pass");
        driver.close();
    }
}



Note- Here Autoit tool has been used to attach the file because by using sendKeys() method we can't upload the file in gmail. Below is the script used to upload the file thru autoit-

WinWaitActive("File Upload")
Send("path of the file")
ControlClick("","&Open","Button1")

ex- path of the file = C:\java learn\important cmd for Java.txt
