[🚀 Feature]: Remote WebDriver - Check if the file download has finished.

[limuyuan]

Feature and motivation

On this page: https://www.selenium.dev/documentation/webdriver/drivers/remote_webdriver/#list-downloadable-files

It said:
List Downloadable Files
Be aware that Selenium is not waiting for files to finish downloading, so the list is an immediate snapshot of what file names are currently in the directory for the given session.

Is it possible that Selenium can natively support the function of "wait for files to finish downloading"?

I found a similar issue #10884 but it was closed.

Usage example

I'm using the sample code here: https://github.com/SeleniumHQ/seleniumhq.github.io/blob/trunk/examples/dotnet/SeleniumDocs/Drivers/RemoteWebDriverTest.cs#L69

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5));
wait.Until(d => ((RemoteWebDriver)d).GetDownloadableFiles().Contains(downloadFileName));

However, the target file was generated immediately as a 0KB file, and there is another .part file, which is making the wait.Until useless.

Is it possible to provide a feature so we can know the file was completely downloaded?

With Edge 131.0.2903.99, there is only one Unconfirmed 645092.crdownload tmp file.
With Chrome 131.0.6778.140, there is only one file <filename>.crdownload tmp file.
With Firefox 133.0.3, there is a 0KB file and another <filename>.part tmp file, which is causing the issue.

Maybe I can edit the wait condition to exclude the .part file to solve this problem...

We don't plan to implement that method natively because we only expose the feature, and users can do what fits them best. We recommend using a framework built on top of that feature, for example Selenide.
