Practice WebSocket testing scenarios from basic connections to advanced real-time patterns.
Establish a WebSocket connection to an echo server and verify the connection is open.
Send a text message to the echo server and verify you receive the same message back.
Handle different WebSocket close codes (1000, 1001, 1006) and verify proper cleanup.
Send and receive JSON-formatted messages with proper serialization/deserialization.
Send and receive binary data (ArrayBuffer, Blob) over WebSocket.
Implement ping/pong heartbeat mechanism to detect connection health.
Implement automatic reconnection with exponential backoff on connection failure.
Simulate a multi-user chat room: join, send messages, see other users' messages.
Implement real-time "user is typing" indicator with debouncing.
Track online/offline status of users in real-time.
Test WebSocket server under load: multiple connections, high message rate.
Ensure messages are processed in correct order with sequence numbers.
