How to Handle File Uploads in Selenium WebDriver When sendKeys() Doesn\'t Work?

Handling Windows File Upload with Selenium WebDriver

Selenium WebDriver provides a convenient way to automate file uploads, but there are some scenarios where the standard approach may not work. This article addresses one such scenario and offers a solution.

Scenario:

The provided element is not clickable, and the standard sendKeys() method fails to trigger a file upload dialog.

Solution:

For Zamzar Website:

• Use sendKeys() to directly input the file path into the input field.

For Uploadify Website:

• Click the Flash element to open the file upload window.
• Use the Robot class to simulate keyboard input and enter the file path.

Detailed Explanation:

Zamzar Website:

• The file input field is an HTML element. Setting its value using sendKeys() should work as expected.

Uploadify Website:

• The upload button is a Flash object without an exposed API for WebDriver.
• Clicking the button opens a native file upload dialog that is outside the control of WebDriver.
• Assuming the file name input has keyboard focus after the dialog opens, you can use Robot to send keystrokes to input the file path.

Alternative Solution (Flash):

• Modify the Flash application to expose internal methods using ActionScript's ExternalInterface API.
• Use WebDriver to make a JavaScript call in the web page to invoke these methods and simulate file upload.

This solution is more technical and requires modifications to the Flash application, but it can provide greater control over the file upload process.
