New tests cover: - ProcessEventType serialization (to_type_string, from_type_string) - BufferedEvent with minimal events and platform metadata - Buffer management (overflow, size tracking, usage calculations) - Backpressure thresholds (70% activation, 50% release) - Backpressure signal propagation and dropped receiver handling - Event ordering preservation across publishes - Large event handling near buffer limits - Reconnection logic and exponential backoff - WAL integration (write before buffer, replay, type preservation) - Error type display and debug formatting - Event conversion between collector-core and eventbus formats - Client ID uniqueness - Shutdown behavior with/without buffered events Coverage improvement: - Line coverage: 58.27% -> 88.37% - Function coverage: 75.81% -> 93.43% Co-Authored-By: Claude Opus 4.5 --- procmond/src/event_bus_connector.rs | 988 ++++++++++++++++++++++++++++ 1 file changed, 988 insertions(+) diff --git a/procmond/src/event_bus_connector.rs b/procmond/src/event_bus_connector.rs index bef50f1..439d93d 100644 --- a/procmond/src/event_bus_connector.rs +++ b/procmond/src/event_bus_connector.rs @@ -1351,4 +1351,992 @@ mod tests { assert_eq!(events.len(), 5);

Test coverage includes: - Lifecycle operations: HealthCheck, UpdateConfig, GracefulShutdown - Health check accuracy: Verifies health data reflects actual component states including Running, WaitingForAgent, ShuttingDown, and Stopped states - Configuration updates: Config changes applied at cycle boundaries, validate_only flag, invalid payloads, out-of-bounds validation - Graceful shutdown: Completes within timeout, marks service as not running - Error handling: Expired deadlines, operation timeouts, actor errors - Concurrent operations: Multiple health checks, mixed operations - Statistics tracking and response metadata preservation 29 integration tests covering the RpcServiceHandler's coordination with the actor pattern for message handling and state management.

Tests implemented: Connection Failures (Task 12): - Broker unavailability handling - WAL persistence during disconnection - Reconnection with backoff - Socket unavailability - Sequence ordering across failures Backpressure (Task 13): - Buffer fill triggers activation signal - Adaptive interval adjustment via actor - WAL prevents data loss at overflow - Release signal when buffer drains Resource Limits (Task 14): - Memory budget enforcement (10MB buffer) - WAL rotation at threshold - Bounded file sizes - Operation timing verification Concurrent Operations (Task 15): - Multiple RPC requests handled correctly - Config updates applied at cycle boundary - Graceful shutdown during operation - BeginMonitoring state transition - Multiple interval adjustments in order - Actor channel backpressure handling - RPC stats tracking under load Integration tests combining multiple failure modes included.
