clustri/src-tauri/tests/api_snapshots_backups.rs

//! Integration tests for the real snapshot, migration, and backup API calls.
//!
//! Every request goes through `Connection::request`, so these tests cover URL
//! construction, form encoding, auth header injection, response envelope
//! unwrapping, and mapping into the public serde structs. Token-mode
//! connections resolve the token from the config, so the methods can be called
//! directly on an added connection without `connect()`.
