TLA+ verified Raft consensus

Specification-Driven Development of Raft Consensus

Prerequisite

1. Download and install TLA+ toolbox

2. Download and install sedeve-kit

   git clone https://github.com/scuptio/sedeve-kit.git
   cd sedeve-kit
   cargo install --path .
   

3. Configure the TLA+ toolbox

Run model check

Model setup, filling constant

Constant example MC

After checking finish, output state database.

Generate trace of the model

Use the state database the toolbox output, generate trace file.

Example,

cd scupt-raft
sedeve_trace_gen  \
   --state-db-path /tmp/raft_action.db  \
   --out-trace-db-path /tmp/raft_trace.db \
   --map-const-path  ./data/raft_map_const.json

After finish executing, the output trace would be store in database file '/tmp/raft_trace.db'

Validate by running deterministic testing

Write test code

Example test_raft.rs

Test Coverage
