This skill provides a specialized testing framework for verifying real-time communication via Server-Sent Events (SSE). It helps developers implement robust tests for event emission, stream formatting, and complex authorization logic, ensuring that sensitive data is only streamed to authorized clients. By offering standardized patterns for mocking asynchronous event emitters and simulating connection lifecycles within Vitest, this skill reduces the complexity of testing long-lived HTTP connections in TypeScript-based backend services.
