- Implemented RecordingLogger and RecordingLoggerFactory for capturing log entries in tests. - Added unit tests for InMemoryChannel, covering constructor behavior, property assignments, channel communication, and disposal. - Created InMemoryTransportOptionsTests to validate default values and customizable options for InMemory transport. - Developed RabbitMqFrameProtocolTests to ensure correct parsing and property creation for RabbitMQ frames. - Added RabbitMqTransportOptionsTests to verify default settings and customization options for RabbitMQ transport. - Updated project files for testing libraries and dependencies.
