"""Tests for WebSocket reconnection and concurrent recv() synchronization.

Test Categories:
- Unit tests: Fast, isolated tests with mocks (run in CI)
- Integration tests: Tests that require external services (skipped in CI)

To run tests locally:
- All tests: pytest tests/api/test_ws_reconnect.py
- Skip network tests: pytest tests/api/test_ws_reconnect.py -m "not network"
- Only network tests: pytest tests/api/test_ws_reconnect.py -m network
- Force run network test: pytest tests/api/test_ws_reconnect.py::TestWebSocketReconnect::test_real_testnet_integration

Note: Network tests are automatically skipped in GitHub Actions CI via GITHUB_ACTIONS env var.
