How to Handle File Upload with Selenium WebDriver on Windows Machines?

Handling File Upload Using Selenium WebDriver on Windows Machines

Selenium WebDriver is a popular tool for automating web browser tasks. One common task is uploading files, which can be especially challenging on Windows machines.

Scenario: Windows File Upload

The user sets out a scenario in which the standard Selenium WebDriver method for file upload, using sendKeys(), is not working. They provide screenshots showing that a file selection window is popping up, but they are unable to interact with it.

Solution

The user has posted on Stack Overflow and found a solution that uses the Robot class to simulate keystrokes in the file selection window. The solution looks something like this:

<code class="java">driver.findElement(By.id("uploadfile")).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);</code>

The Robot class inputs the specified file path with keystrokes. It is a "blind" technique, as Selenium does not provide direct access to the file selection dialog. This approach assumes that the cursor is in the file name input after the window has been opened.

Alternatives

The user also mentions an alternative method using Flash. However, this involves modifying the Flash application's source code and using JavaScript to call into it. It is a more complex and less reliable approach.
