- Add test for peer restart detection and session recovery
- Add test for nonce desynchronization detection
- Add test for concurrent encryption thread safety
- Add test for session stale detection
- Add test for handshake after decryption failure
- Add integration test for peer presence tracking and reconnection
- Add integration test for encrypted messages after peer restart
These tests ensure:
- Sessions properly recover when a peer restarts
- Nonce desynchronization is detected correctly
- Encryption operations are thread-safe under concurrent load
- Identity announcements are sent on reconnection after silence
- Encrypted messages work after session re-establishment
- Fixed mock service property overrides to match base class properties
- Added missing CryptoKit imports where needed
- Fixed immutable property assignments by creating new instances
- Replaced XCTAssertThrows with XCTAssertThrowsError
- Fixed DeliveryAck serialization method names (serialize -> encode)
- Fixed unused variable warnings
- Ensured all BitchatPacket modifications create new instances
- Fixed BitchatMessage property mutations by creating new instances
All test targets now build successfully for both iOS and macOS platforms.
- Created test utilities and helpers for common test operations
- Implemented Binary Protocol tests covering encoding/decoding, compression, and padding
- Added Noise Protocol tests for handshake, encryption, and session management
- Created Public Chat E2E tests for broadcasting, routing, TTL, and mesh topologies
- Implemented Private Chat E2E tests for direct messaging, delivery ACKs, and retry logic
- Added Integration tests for multi-peer scenarios, network resilience, and mixed traffic patterns
- Created mock implementations for BluetoothMeshService and NoiseSession
Test coverage includes:
- Protocol layer (binary encoding, message serialization)
- Security layer (Noise handshake, encryption/decryption)
- Application layer (public/private messaging, delivery tracking)
- Network scenarios (mesh topology, partitions, churn)
- Performance and stress testing
