# Test Scenarios

Keep this file as the reusable verification checklist while implementing
`PLAN.md`.

## Automated

- `just check`
  - Runs formatting, all Rust tests, and clippy.
  - Current coverage:
    - `GET /` serves the static browser page.
    - `GET /healthz` reports `ok`.
    - `POST /api/uploads` creates `meta.json` and chunk directories.
    - `POST /api/uploads` rejects an empty file name.
    - `PUT /api/uploads/:id/chunks/:index` stores validated chunk files.
    - `PUT /api/uploads/:id/chunks/:index` rejects wrong-size chunks.
    - `PUT /api/uploads/:id/chunks/:index` accepts duplicate chunks.
    - `GET /api/uploads/:id` reports completed chunks from disk.
    - `POST /api/uploads/:id/complete` assembles verified chunks.
    - `POST /api/uploads/:id/complete` rejects incomplete uploads.

## Manual

These scenarios come from `PLAN.md` and should be retested as the matching
features land.

- Upload a small file in one pass.
- Upload a file larger than one chunk.
- Kill the browser tab mid-upload and resume.
- Restart the Rust server mid-upload and resume.
- Interrupt the network and resume.
- Retry a duplicate chunk and confirm it is accepted idempotently.
- Attempt an invalid chunk index and confirm it is rejected.
- Attempt a wrong-size non-final chunk and confirm it is rejected.
- Complete an upload and compare the final file with the source file:

```sh
sha256sum source-file data/complete/uploaded-file
```
