Upload a File by Using Robot Class

Hi all, in this article I will explain how to upload a file by using Robot class. I want to keep this article as simple as possible. So, I will start with the scenario.

Test Scenario

• Open a demo website https://blueimp.github.io/jQuery-File-Upload/ 
• Click “Add files…” button.
• Use “uploadFileWithRobot” method to upload sw-test-academy.png image file under images folder.
• Check that image has been uploaded as shown below.

Test Code

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.Assert;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

import java.awt.*;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;
import java.awt.event.KeyEvent;
import java.util.concurrent.TimeUnit;

public class RobotTest {

    public WebDriver driver;
    public WebDriverWait wait;
    private static String filePath = System.getProperty("user.dir") + "\\images\\sw-test-academy.png";

    @BeforeMethod
    public void setup () {
        driver = new ChromeDriver();
        driver.navigate().to("https://blueimp.github.io/jQuery-File-Upload/");
        driver.manage().timeouts().pageLoadTimeout(15, TimeUnit.SECONDS);
        wait = new WebDriverWait(driver,10);
        driver.manage().window().maximize();
    }

    @Test
    public void robotTest () throws InterruptedException {
        //Click Image Upload
        wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector(".btn.btn-success.fileinput-button")));
        driver.findElement(By.cssSelector(".btn.btn-success.fileinput-button")).click();
        uploadFileWithRobot(filePath);
        Assert.assertTrue(wait.until(ExpectedConditions.visibilityOfElementLocated
                (By.cssSelector(".name"))).getText().equals("sw-test-academy.png"));
        //I added sleep to see the result with my eyes. If you want you can remove below line.
        Thread.sleep(2000);
    }

    @AfterMethod
    public void teardown () {
        driver.quit();
    }

    //File upload by Robot Class
    public void uploadFileWithRobot (String imagePath) {
        StringSelection stringSelection = new StringSelection(imagePath);
        Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
        clipboard.setContents(stringSelection, null);

        Robot robot = null;

        try {
            robot = new Robot();
        } catch (AWTException e) {
            e.printStackTrace();
        }

        robot.delay(250);
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.keyRelease(KeyEvent.VK_ENTER);
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.delay(150);
        robot.keyRelease(KeyEvent.VK_ENTER);
    }
}
