# tests/manual/test-sse-working.js @source-hash: 6639615c06932383 @generated: 2026-02-10T00:41:55Z ## Purpose Manual test script for validating Server-Sent Events (SSE) connection with session-based communication. Tests the complete SSE handshake flow including session ID extraction and subsequent authenticated API calls. ## Key Components ### SSE Parser (L10-26) - `parseSSEData(chunk)`: Parses raw SSE data chunks into structured messages - Extracts `data: ` prefixed lines and attempts JSON parsing - Returns array of parsed message objects - Silently ignores non-JSON data lines ### Main SSE Connection (L29-63) - Establishes HTTP GET request to `http://localhost:3001/sse` - Sets proper SSE headers (`Accept: text/event-stream`, `Cache-Control: no-cache`) - Monitors for `connection/established` messages containing session ID - Triggers follow-up POST test after 1 second delay when session ID received ### POST Request Testing (L70-122) - `testPostRequest(sessionId)`: Tests JSON-RPC API call with session authentication - Sends `tools/list` request with `X-Session-ID` header - Handles both JSON and non-JSON responses - Keeps connection alive for 2 seconds to observe any SSE responses ## Dependencies - Node.js `http` module for HTTP client operations - Node.js `https` module (imported but unused) ## Execution Flow 1. Establish SSE connection to localhost:3001 2. Parse incoming SSE data for session establishment 3. Extract session ID from `connection/established` message 4. Wait 1 second, then send authenticated POST request 5. Display all responses and keep script running for manual inspection ## Test Configuration - Target server: `localhost:3001/sse` - Session timeout: 1 second before POST request - Response observation window: 2 seconds after POST completion - Manual termination required (Ctrl+C) ## Error Handling - Connection errors logged to console - SSE parsing errors silently ignored - JSON parsing failures handled gracefully - POST request errors logged with context
