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

Question

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.

Answer 1

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.

Thanks Alex,

Java Robot API helped me for uploading file. I was fedup with File Upload using WebDriver. Following is the code I used (Small modification to yours):

Robot robot = new Robot(); robot.delay(1000); 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); robot.delay(1000); 

Answer 3

Thanks Alex! I needed this since I could not get the sendKeys function to work when used via Play framework 2.1 (fluentlenium wrapper). I am testing over Firefox [17.0.7] for Mac and had to make a few mods to get it working. Below is an approximation of the final snippet I used.

 val file = new File(PATH_TO_IPA) val stringSelection: StringSelection = new StringSelection(file.getAbsolutePath) Toolkit.getDefaultToolkit.getSystemClipboard().setContents(stringSelection, null) val robot: Robot = new Robot() // Cmd + Tab is needed since it launches a Java app and the browser looses focus robot.keyPress(KeyEvent.VK_META) robot.keyPress(KeyEvent.VK_TAB) robot.keyRelease(KeyEvent.VK_META) robot.keyRelease(KeyEvent.VK_TAB) robot.delay(500) robot.keyPress(KeyEvent.VK_META) robot.keyPress(KeyEvent.VK_SHIFT) robot.keyPress(KeyEvent.VK_G) robot.keyRelease(KeyEvent.VK_META) robot.keyRelease(KeyEvent.VK_SHIFT) robot.keyRelease(KeyEvent.VK_G) robot.keyPress(KeyEvent.VK_META) robot.keyPress(KeyEvent.VK_V) robot.keyRelease(KeyEvent.VK_META) robot.keyRelease(KeyEvent.VK_V) robot.keyPress(KeyEvent.VK_ENTER) robot.keyRelease(KeyEvent.VK_ENTER) robot.delay(500) robot.keyPress(KeyEvent.VK_ENTER) robot.keyRelease(KeyEvent.VK_ENTER)

The switching of application on Mac is much better to do with AppleScript. AppleScript is integrated to system, so it will be always functional and does not depend on order of apps on Cmd+Tab. Your test/app will be less fragile. https://developer.apple.com/library/content/documentation/AppleScript/Conceptual/AppleScriptLangGuide/reference/ASLR_cmds.html

You need only detect you are on mac and has name of the application.

Runtime runtime = Runtime.getRuntime(); String[] args = { "osascript", "-e", "tell app \"Chrome\" to activate" }; Process process = runtime.exec(args);
