Overview

This directly sets file(s) on an <input type="file"> element without touching the OS-level native file picker dialog at all. .set_input_files(paths) What it does: Sets file(s) on a file input element directly, bypassing the native OS file picker dialog. Types/params: Pointers: Works even on hidden file inputs (a styled "Upload" button triggering a hidden <input type="file">) — no OS-level automation needed. download = download_info.value As with new-tab handling, the with ... expect_download() pattern registers the listener before the triggering click.

paths — one of:
A single string path → uploads one file
A list of string paths → uploads multiple files (if the input supports multiple)
An empty list [] → clears the current selection
