From a14dcbc03494c1f418dded62418a67df437ee5ab Mon Sep 17 00:00:00 2001 From: maziggy Date: Fri, 12 Dec 2025 15:52:35 +0100 Subject: [PATCH] Frontend WebSocket Tests Summary Expanded the useWebSocket.test.ts from minimal coverage to 20 comprehensive tests covering: WebSocket Mock Tests (6 tests) - Creates WebSocket with correct URL - Starts in CONNECTING state - Transitions to OPEN state - Can receive messages - Can close connection - Tracks all instances Hook Connection Tests (2 tests) - Connects to WebSocket on mount - Reports connected state when WebSocket opens Message Handling Tests (9 tests) - Updates printer status in query cache on printer_status message - Preserves wifi_signal when new value is null - Invalidates archives on print_complete message - Invalidates archives on archive_created message - Invalidates archives on archive_updated message (new handler for timelapse auto-assignment) - Ignores pong messages without error - Handles malformed JSON gracefully - Handles unknown message types gracefully sendMessage Tests (2 tests) - Sends JSON message when connected - Does not send when disconnected Reconnection Tests (2 tests) - Reconnects after connection closes - Cleans up on unmount Key Fixes - Fixed MSW (Mock Service Worker) conflict by: a. Adding addEventListener/removeEventListener to MockWebSocket class b. Updating MSW setup to bypass WebSocket requests c. Properly managing WebSocket mock lifecycle in each test Test Results: - Frontend: 137 tests passed (9 test files) - Backend: 346 tests passed --- .../tests/unit/services/test_bambu_mqtt.py | 193
