Target: 90%+ coverage across all metrics:

• Lines: 90%
• Functions: 90%
• Branches: 90%
• Statements: 90%

Tests for core QUIC transport functionality:

• ✅ Connection establishment (0-RTT, 1-RTT)
• ✅ Stream multiplexing (bidirectional, unidirectional)
• ✅ Error handling (connection loss, stream errors)
• ✅ Connection migration (network changes)
• ✅ Performance characteristics
• ✅ Edge cases and memory management
• ✅ Stream prioritization

Coverage: Core transport layer implementation

Tests for QUIC proxy integration:

• ✅ Agent communication (spawn, execute, terminate)
• ✅ Multi-agent scenarios (concurrent operations)
• ✅ HTTP/2 fallback mechanisms
• ✅ Configuration loading (environment variables)
• ✅ Error recovery (retry logic, stream isolation)
• ✅ Memory operations (dedicated streams)
• ✅ Concurrency scenarios (100+ concurrent ops)

Coverage: Proxy layer and agent integration

Tests for complete workflows:

• ✅ Swarm initialization (mesh, hierarchical topologies)
• ✅ Task orchestration (parallel, sequential execution)
• ✅ Agent lifecycle (spawn → execute → terminate)
• ✅ Full SPARC workflow (5 phases)
• ✅ Stress testing (50-agent, 100-step workflows)
• ✅ Real-world scenarios (code review, deployment, data pipelines)

Coverage: End-to-end system integration

The test suite includes performance validation based on research targets:

Tests use mock implementations of QUIC primitives:

• MockQuicConnection: Simulates QUIC connections with 0-RTT support
• MockQuicSendStream: Simulates send streams with priority and flow control
• MockQuicRecvStream: Simulates receive streams
• MockQuicConnectionPool: Simulates connection pooling and management

These mocks provide realistic timing and behavior based on QUIC research.

Tests use realistic scenarios:

• Agent types: researcher, coder, tester, reviewer, architect
• Task types: analyze, code, test, review, deploy
• Stream priorities: Critical (0), High (64), Medium (128), Low (192)
• Flow control limits: 1MB to 100MB based on priority

Tests are designed to run in CI environments:

• Fast execution (< 5 minutes for full suite)
• Deterministic results
• No external dependencies
• Parallel test execution
• Comprehensive coverage reporting

When QUIC implementation is available:

1. Replace mocks with actual QUIC client/server
2. Add performance regression tests
3. Add network condition simulation (latency, packet loss)
4. Add TLS certificate validation tests
5. Add connection migration stress tests
6. Add QLOG debugging tests
