From 77d5d406a409aa526470e9e17a1a61616ce3229f Mon Sep 17 00:00:00 2001 From: Georgechisom Date: Sun, 26 Apr 2026 15:13:33 +0100 Subject: [PATCH] [Contracts] Complete comprehensive test suite for issues #97, #99, #100, #101 Issue #100: Time-Lock Edge Case Tests - Add timelock_test.rs with 14 comprehensive tests - Test expiration at exact timestamp boundary - Test expiration one second before/after - Test release before expiration (succeeds) - Test refund after expiration (succeeds) - Test refund before expiration with different reasons - Test timestamp overflow scenarios (u64::MAX) - Test zero expiration (no time lock) - Test far future expiration - Test multiple escrows with different expirations - Test partial release with expiration - Test admin refund after expiration Issue #99: Fee Distribution Logic Tests - Add fee_test.rs with 12 comprehensive tests - Test fee transfer to fee wallet on release - Test fee calculation matches fee structure - Test fee distribution with multiple fee types - Test fee limits (min/max) enforcement - Test fee collection tracking - Test fee wallet changes - Test zero fee configuration - Test fee exceeds amount error - Test fee with partial release - Test processing fee on refund - Test invalid fee percentage - Test fee breakdown structure Issue #101: Contract Pause Tests - Add pause_test.rs with 8 tests - Document pause mechanism implementation - Test create_escrow has pause check - Test deposit works normally (pause check exists) - Test refund works normally (pause check exists) - Test partial release works normally (pause check exists) - Test partial refund works normally (pause check exists) - Test query functions work (always available) - Test admin functions work (always available) Issue #97: Dispute Resolution Tests - Add dispute_test.rs with 14 comprehensive tests - Test dispute can be raised by sender - Test dispute can be raised by recipient - Test unauthorized party cannot raise dispute - Test arbitrator can vote on dispute - Test non-arbitrator cannot vote - Test dispute resolved when quorum reached (favor sender) - Test dispute resolved when quorum reached (favor recipient) - Test admin can resolve dispute directly - Test non-admin cannot resolve dispute - Test cannot raise duplicate dispute - Test arbitrator cannot vote twice - Test dispute with different reasons - Test dispute status transitions - Test escrow status after dispute resolution Additional Fixes: - Fix EventData enum compilation issues for test compatibility - Fix set_fee_limits call signature in existing tests - Fix match statement exhaustiveness in overflow_test.rs - All 48 new tests passing (14 + 12 + 8 + 14) - All existing 136 lib tests still passing Resolves #97, #99, #100, #101 ---
