Refactor and enhance tests for call graph extractors and connection management
- Updated JavaScriptCallGraphExtractorTests to improve naming conventions and test cases for Azure Functions, CLI commands, and socket handling. - Modified NodeCallGraphExtractorTests to correctly assert exceptions for null inputs. - Enhanced WitnessModalComponent tests in Angular to use Jasmine spies and improved assertions for path visualization and signature verification. - Added ConnectionState property for tracking connection establishment time in Router.Common. - Implemented validation for HelloPayload in ConnectionManager to ensure required fields are present. - Introduced RabbitMqContainerFixture method for restarting RabbitMQ container during tests. - Added integration tests for RabbitMq to verify connection recovery after broker restarts. - Created new BinaryCallGraphExtractorTests, GoCallGraphExtractorTests, and PythonCallGraphExtractorTests for comprehensive coverage of binary, Go, and Python call graph extraction functionalities. - Developed ConnectionManagerTests to validate connection handling, including rejection of invalid hello messages and proper cleanup on client disconnects.
