How Can I Upload Files With Selenium WebDriver When a Separate Window Pops Up?

Handling Windows File Upload Using Selenium WebDriver

In Selenium WebDriver, handling file uploads can be tricky, especially in scenarios where a separate window pops up. This article provides solutions for uploading files in different web contexts and addresses the issue of finding the window handle.

Problem Statement

Using Selenium WebDriver, you encounter difficulties uploading a file when a separate window appears, similar to the scenario depicted in the provided screenshot.

Solution

In most cases, to handle file uploads, you can simply use the sendKeys method to specify the path to the desired file. For instance:

WebElement fileInput = driver.findElement(By.name("uploadfile"));
fileInput.sendKeys("C:/path/to/file.jpg");

For websites like Zamzar, this straightforward approach should work without issues. However, in cases like Uploadify where Flash objects are involved, the situation becomes more complex.

No-API Approach: Using the Robot Class

Since WebDriver lacks an API for working with Flash objects or browser dialogs, a workaround is to blindly type the file path using the Robot class. After clicking the Flash element to trigger the file browsing window, you can simulate keystrokes to enter the path:

driver.findElement(By.id("SWFUpload_0")).click();
Robot r = new Robot();
r.keyPress(KeyEvent.VK_C); // Example: Press the 'C' key

Alternative: Modifying Flash Source Code

A more advanced solution involves modifying the source code of the Flash application to expose its internal methods, allowing JavaScript to interact with them. Subsequently, WebDriver can execute JavaScript commands to call those exposed methods and control the file upload process.

Conclusion

Handling file uploads using WebDriver can be straightforward or complex depending on the underlying technology involved. By understanding these techniques, you can effectively manage file uploads in various scenarios.
