How to handle windows file upload using Selenium WebDriver?

I have seen lots of questions and solutions on File upload using Selenium WebDriver on Stack Overflow. But none of them are working for following scenario.

Someone has given a solution as following

// assuming driver is a healthy WebDriver instance
WebElement fileInput = driver.findElement(By.name("uploadfile"));
fileInput.sendKeys("C:/path/to/file.jpg");

But still I can't find window handle. How can I work on that?

I am looking for a solution for the scenario above.

Please check this on any of the following websites.

http://www.uploadify.com/demos/
http://www.zamzar.com/

Solution 1:

// assuming driver is a healthy WebDriver instance
WebElement fileInput = driver.findElement(By.name("uploadfile"));
fileInput.sendKeys("C:/path/to/file.jpg");

Hey, that's mine from somewhere :).

In case of the Zamzar web, it should work perfectly. You don't click the element. You just type the path into it. To be concrete, this should be absolutely ok:

driver.findElement(By.id("inputFile")).sendKeys("C:/path/to/file.jpg");

In the case of the Uploadify web, you're in a pickle, since the upload thing is no input, but a Flash object. There's no API for WebDriver that would allow you to work with browser dialogs (or Flash objects).

So after you click the Flash element, there'll be a window popping up that you'll have no control over. In the browsers and operating systems I know, you can pretty much assume that after the window has been opened, the cursor is in the File name input. Please, make sure this assumption is true in your case, too.

If not, you could try to jump to it by pressing Alt + N, at least on Windows...

If yes, you can "blindly" type the path into it using the Robot class. In your case, that would be something in the way of:

driver.findElement(By.id("SWFUpload_0")).click();
Robot r = new Robot();
r.keyPress(KeyEvent.VK_C);        // C
r.keyRelease(KeyEvent.VK_C);
r.keyPress(KeyEvent.VK_COLON);    // : (colon)
r.keyRelease(KeyEvent.VK_COLON);
r.keyPress(KeyEvent.VK_SLASH);    // / (slash)
r.keyRelease(KeyEvent.VK_SLASH);
// etc. for the whole file path

r.keyPress(KeyEvent.VK_ENTER);    // confirm by pressing Enter in the end
r.keyRelease(KeyEvent.VK_ENTER);

It sucks, but it should work. Note that you might need these: How can I make Robot type a `:`? and Convert String to KeyEvents (plus there is the new and shiny KeyEvent#getExtendedKeyCodeForChar() which does similar work, but is available only from JDK7).

For Flash, the only alternative I know (from this discussion) is to use the dark technique:

First, you modify the source code of you the flash application, exposing internal methods using the ActionScript's ExternalInterface API. Once exposed, these methods will be callable by JavaScript in the browser.

Second, now that JavaScript can call internal methods in your flash app, you use WebDriver to make a JavaScript call in the web page, which will then call into your flash app.

This technique is explained further in the docs of the flash-selenium project. (http://code.google.com/p/flash-selenium/), but the idea behind the technique applies just as well to WebDriver.

Solution 2:

Below code works for me :

public void test() {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.freepdfconvert.com/pdf-word");
    driver.findElement(By.id("clientUpload")).click();
    driver.switchTo()
            .activeElement()
            .sendKeys(
                    "/home/likewise-open/GLOBAL/123/Documents/filename.txt");
    driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
    driver.findElement(By.id("convertButton"));

Solution 3:

Using C# and Selenium this code here works for me, NOTE you will want to use a parameter to swap out "localhost" in the FindWindow call for your particular server if it is not localhost and tracking which is the newest dialog open if there is more than one dialog hanging around, but this should get you started:

    using System.Threading;
    using System.Runtime.InteropServices;
    using System.Windows.Forms;
    using OpenQA.Selenium;

    [DllImport("user32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool SetForegroundWindow(IntPtr hWnd);

    [DllImport("user32.dll", EntryPoint = "FindWindow")]
    public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    public static void UploadFile(this IWebDriver webDriver, string fileName)
    {
        webDriver.FindElement(By.Id("SWFUpload_0")).Click();
        var dialogHWnd = FindWindow(null, "Select file(s) to upload by localhost");
        var setFocus = SetForegroundWindow(dialogHWnd);
        if (setFocus)
        {
            Thread.Sleep(500);
            SendKeys.SendWait(fileName);
            SendKeys.SendWait("{ENTER}");
        }
    }

Solution 4:

I made use of sendkeys in shell scripting using a vbsscript file. Below is the code in vbs file,

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys "C:\Demo.txt"
WshShell.SendKeys "{ENTER}"

Below is the selenium code line to run this vbs file,

driver.findElement(By.id("uploadname1")).click();
Thread.sleep(1000);
Runtime.getRuntime().exec( "wscript C:/script.vbs" );
