File uploading using Auto-It and Robot Class

The Problem

Native OS file-upload dialogs are not part of the browser's DOM, so WebDriver cannot directly interact with them using normal locators.

AutoIt Approach

AutoIt is a separate Windows scripting tool that can be used to write a small script that automatically interacts with the native file dialog, triggered from the Java test via a system command.

Robot Class Approach

Java's built-in Robot class can simulate keyboard actions (like typing a file path and pressing Enter) directly at the OS level once the file dialog opens.

Simplest Alternative

When the upload element is a standard <input type="file">, simply calling sendKeys(filePath) directly on it avoids the native dialog entirely and is the preferred approach whenever possible.
