OpenRaft Test Suite Integration +//! +//! This file uses OpenRaft's `openraft::testing::Suite` to verify that +//! `RocksdbLogStore` and `TestStateMachine` implementations conform to +//! the OpenRaft specification. +//! +//! ## Current Status +//! +//! - **LogStore tests**: 26 tests, all passing +//! - **StateMachine tests**: 4 tests, ignored (snapshot feature incomplete) +//! +//! ## Running Tests +//! +//! ```bash +//! # Run LogStore tests +//! cargo test --package raft --test openraft_suite +//! +//! # Run all tests including ignored ones (after StateMachine is complete) +//! cargo test --package raft --test openraft_suite -- --include-ignored +//! ``` +//! +//! ## Implementation Notes +//! +//! This test uses a simplified `TestStateMachine` instead of the full `KiwiStateMachine` +//! because the snapshot functionality in `KiwiStateMachine` is still under development. +//! Once `KiwiStateMachine` snapshot support is complete, replace `TestStateMachine` with +//! `KiwiStateMachine` and remove the `#[ignore]` attribute from StateMachine tests. +//! +//! ## TODO: Tests to Enable After StateMachine Snapshot Implementation +//! +//! The following tests are currently ignored and should be enabled once +//! `KiwiStateMachine` properly implements snapshot functionality: +//! +//! 1. `apply_single` - Apply single entry to state machine +//! 2. `apply_multiple` - Apply multiple entries to state machine +//! 3. `snapshot_meta` - Snapshot metadata correctness +//! 4. `transfer_snapshot` - Snapshot transfer between state machines +//! +//! Requirements for `KiwiStateMachine` to pass these tests: +//! - `get_current_snapshot()` must return the built snapshot (not `None`) +//! - `install_snapshot()` must update `last_applied` and `last_membership` +//! - `build_snapshot()` must include correct `last_log_id` and `last_membership` + +use std::collections::BTreeMap;
