File Uploads and Choosers

Chooser fixtures

These inputs are meant to exercise single-file, multi-file, accept-filter, and directory picker behavior through the native browser file chooser.

File-drop smoke test

This is a quick file-drop path for the upload endpoint. Use the dedicated Drag and Drop page for lifecycle, mixed payload, and iframe coverage.

No dropped files yet.

Local selection snapshot

The browser will often preserve previous selections unless the input is manually cleared, so this snapshot is useful when testing same-file reselection.

Manual checklist
  • Cancel the native picker and confirm the selection remains unchanged.
  • Re-select the same file twice to inspect change-event semantics.
  • Try a directory with nested files and inspect webkitRelativePath in the response.
