From b606e414f98cb417ccd952ee98ab3af51df2d797 Mon Sep 17 00:00:00 2001 From: StellarDataLab Bot Date: Fri, 26 Jun 2026 01:16:50 +0100 Subject: [PATCH] test: add comprehensive arbiter authorization security tests - Adds test_arbiter_security.rs with 10 comprehensive security tests - Verifies arbiter cannot call resolve_dispute on non-Disputed milestones - Tests all 5 non-Disputed MilestoneStatus states: Pending, ProofSubmitted, Confirmed, ConfirmedHeld, Resolved - Verifies arbiter cannot call confirm_milestone (buyer-only operation) - Verifies arbiter cannot call cancel_shipment (buyer-only operation) - Validates only arbiter can resolve after buyer raises dispute - Tests arbiter cannot bypass dispute process for unilateral fund redirection - All tests verify proper authorization checks prevent unauthorized access - Security coverage prevents fund theft and unauthorized state transitions --- contracts/chainsetttle/src/lib.rs | 1 + .../chainsetttle/src/test_arbiter_security.rs | 462 ++++++++++++++++++ 2 files changed, 463 insertions(+) create mode 100644 contracts/chainsetttle/src/test_arbiter_security.rs diff --git a/contracts/chainsetttle/src/lib.rs b/contracts/chainsetttle/src/lib.rs index 55e528c..269ea29 100644 --- a/contracts/chainsetttle/src/lib.rs +++ b/contracts/chainsetttle/src/lib.rs @@ -3745,6 +3745,7 @@ mod benchmarks; pub mod constants; mod property_tests; mod test; +mod test_arbiter_security; mod test_upgrade; mod test_concurrent_disputes; mod test_boundaries; diff --git a/contracts/chainsetttle/src/test_arbiter_security.rs b/contracts/chainsetttle/src/test_arbiter_security.rs new file mode 100644 index 0000000..621e0c6 --- /dev/null +++ b/contracts/chainsetttle/src/test_arbiter_security.rs @@ -0,0 +1,462 @@ +#![cfg(test)] + +extern crate std; + +use super::*; +use soroban_sdk::{ + testutils::{Address as _, Ledger as _, Symbol}, + token, vec, Address, BytesN, Env, String, +}; +use std::format; + +// ============================================================ +// TEST SETUP +// ============================================================ + +struct TestSetup { + env: Env, + contract_id: Address, + token_id: Address, + buyer: Address, + supplier: Address, + logistics: Address, + arbiter: Address, +} + +fn setup() -> TestSetup { + let env = Env::default(); + env.mock_all_auths(); + + let contract_id = env.register(ChainSettleContract, ()); + + let token_admin = Address::generate(&env); + let token_id = env + .register_stellar_asset_contract_v2(token_admin.clone()) + .address(); + let token_client = token::StellarAssetClient::new(&env, &token_id); + + let buyer = Address::generate(&env); + let supplier = Address::generate(&env); + let logistics = Address::generate(&env); + let arbiter = Address::generate(&env); + + token_client.mint(&buyer, &10_000_000_000); + + let client = ChainSettleContractClient::new(&env, &contract_id); + client.init(&buyer); + + TestSetup { + env, + contract_id, + token_id, + buyer, + supplier, + logistics, + arbiter, + } +} + +fn build_milestones(env: &Env) -> soroban_sdk::Vec { + vec![ + env, + Milestone { + name: String::from_str(env, "Goods Dispatched"), + payment_percent: 100, + proof_hash: String::from_str(env, ""), + status: MilestoneStatus::Pending, + release_after_ledger: 0, + proof_submitted_ledger: None, + dispute_opened_ledger: None, + }, + ] +} + +fn single_buyer_vec(env: &Env, buyer: &Address) -> soroban_sdk::Vec
