Java – One solution for File Upload using Java Robot API with Selenium WebDriver by Java

file-uploadjavaselenium-webdriver

I saw that lots of people have Problems uploading a file in a test Environment with Selenium WebDriver. I use the selenium WebDriver and java, and had the same problem. I finally have found a solution, so i will post it here hoping that it helps someone else.

When i need to upload a file in a test, i click with Webdriver in the button and wait for the window "Open" to pop. And then i copy the path to the file in the clipboard and then paste it in the "open" window and click "Enter". This is working because when the window "open" pops up, the focus is always in the "open" button.

You will need these classes and method:

import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.awt.Toolkit;
import java.awt.datatransfer.StringSelection;


public static void setClipboardData(String string) {
   StringSelection stringSelection = new StringSelection(string);
   Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stringSelection, null);
}

And that is what i do, just after opening the "open" window:

setClipboardData("C:\\path to file\\example.jpg");
//native key strokes for CTRL, V and ENTER keys
Robot robot = new Robot();
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.keyRelease(KeyEvent.VK_ENTER);

And that´s it. It is working for me, i hope it works for some of you.

Best Solution

Actually, there is an in-built technique for this, too. It should work in all browsers and operating systems.

Selenium 2 (WebDriver) Java example:

// assuming driver is a healthy WebDriver instance
WebElement fileInput = driver.findElement(By.xpath("//input[@type='file']"));
fileInput.sendKeys("C:/path/to/file.jpg");

The idea is to directly send the absolute path to the file to an element which you would usually click at to get the modal window - that is <input type='file' /> element.
