WebSocket mocking not yet implemented

Error message

WebSocket mocking not yet implemented

What it means

Placeholder in the testing setup helper's mockWebSocket(): WebSocket mocking is not implemented, so calling it only logs and does nothing — tests relying on it get no interception. HTTP fetch mocking above it is functional.

Solutions

1. Implement the WebSocket mock in setup-teardown.ts (e.g. using a mock-socket style fake) or mark the test as skipped until supported.
2. Use a real loopback WebSocket server in tests instead of mocking.
3. Guard tests requiring WebSocket mocking so they fail with a clear skip reason rather than this error.

When it happens

Trigger: Test setup requests a mocked WebSocket transport before the mock implementation exists; any test calling setupTeardown with transport 'websocket' hits this unimplemented branch.

Common situations: See trigger scenarios.
