Subject: test(charging-station): add Transaction Management tests
X-Git-Tag: ocpp-server@v3.0.0~131
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=62d293816286e6925404b76abd7864721f6be14e;p=e-mobility-charging-stations-simulator.git

test(charging-station): add Transaction Management tests

Implement 17 tests covering transaction query methods, energy meters,
transaction state management, and concurrent transaction scenarios.

- Add transaction query tests: hasTransaction, getConnectorIdByTransactionId
- Add energy meter tests: getEnergyActiveImportRegisterByTransactionId
- Add state management tests: isRegistered, stationInfo properties
- Add concurrent transaction tests: hasEvses checks
- Enhance ChargingStationTestUtils with 6 transaction helper methods

All 217 tests pass.
