From: Jérôme Benoit Date: Fri, 27 Feb 2026 01:40:48 +0000 (+0100) Subject: test(charging-station): add lifecycle and connector/EVSE state tests (Wave 2) X-Git-Tag: ocpp-server@v3.0.0~137 X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=291f90538b9b038bbf4b2fd9b3c936d9985dc1de;p=e-mobility-charging-stations-simulator.git test(charging-station): add lifecycle and connector/EVSE state tests (Wave 2) Task 4 - Lifecycle tests (11 tests): - start(): initial, idempotent, starting flag - stop(): normal, idempotent, stopping flag, clears bootNotificationResponse - Restart after stop - delete(): stopped station, running station auto-stop - Concurrent operation guards Task 5 - Connector/EVSE state tests (22 tests): - Connector queries: hasConnector, getConnectorStatus, isConnectorAvailable - Connector 0 (shared power) special behavior - EVSE mode vs non-EVSE mode configurations - EVSE queries: getEvseStatus, getEvseIdByConnectorId - Invalid connector/EVSE ID edge cases Total: 33 tests, all passing Fixed ESLint errors in test utilities --- diff --git a/tests/charging-station/ChargingStation.test.ts b/tests/charging-station/ChargingStation.test.ts index
