+## Testing
+
+```bash
+go build ./... && go vet ./...
+go test ./...                 # unit — no network, no vendor mocks
+go test -race ./...
+go test -tags=integration ./...   # live OnlyOffice (skip without creds)
+```
+
+Unit tests are pure Go (parsers, encoders, conversions). Integration tests
+(`//go:build integration`) hit a live instance and **skip** cleanly when the
+env is missing, so `go test ./...` stays green offline. New endpoints ship with
+an integration test before merge (policy in [`AGENTS.md`](AGENTS.md)).
+
+Live runs need credentials (`ONLYOFFICE_URL`, `ONLYOFFICE_USER`,
+`ONLYOFFICE_PASS`) and, per backend:

+- **Elasticsearch** (`oo search`, own index) — ES lives on `127.0.0.1:9200`
+  inside the OnlyOffice VM; expose it over SSH
+  (`-L 9200:127.0.0.1:9200`) and set `ONLYOFFICE_ES_URL`
+  (see [`docs/elasticsearch.md`](docs/elasticsearch.md)).
+- **SQL backend** (`FileClient`, `SQLFileStore`) — MySQL on `127.0.0.1:3306`
+  in the same VM; tunnel `-L 3306:127.0.0.1:3306`, then set `ONLYOFFICE_DSN`
+  (see [`docs/community-server-db.md`](docs/community-server-db.md)).
+  `ONLYOFFICE_PG_TEST_FILE_ID` / `ONLYOFFICE_PG_TEST_FOLDER_ID` select a real
+  file for the REST cross-check; `MINIO_*` enable the download check.
+
+### rclone WebDAV mount
+
+`deploy/docker-compose.rclone-webdav.yml` mounts the Documents tree as a
+filesystem (compose, not systemd; container `rclone-webdav`) — read/write like
+a normal FS over the `oo-webdav` sidecar. Setup, smoke log and limitations:
+[`docs/rclone-webdav.md`](docs/rclone-webdav.md).
