* feat(ocpp2): implement in-memory auth cache with rate limiting and TTL
Add InMemoryAuthCache with comprehensive security features:
- LRU eviction when cache reaches capacity
- TTL-based automatic expiration (configurable, default 1h)
- Built-in rate limiting (10 req/min per identifier, configurable)
- Memory usage tracking and comprehensive statistics
- 45 conformance tests covering G03.FR.01 requirements
Security improvements:
- Mitigates S2 (rate limiting prevents DoS on auth endpoints)
- Mitigates S3 (TTL prevents stale authorization persistence)
- Tracks evictions, hits, misses, expired entries
Completes Phase 2.3 (Security Hardening) and G03.FR.01 cache tests.
* refactor(ocpp2): integrate InMemoryAuthCache into auth service
Update factory, interfaces, and service to support cache integration:
- AuthComponentFactory.createAuthCache() now instantiates InMemoryAuthCache
- Add evictions field to CacheStats interface
- Add rateLimit field to AuthStats interface (blockedRequests, rateLimitedIdentifiers, totalChecks)
- Make OCPPAuthServiceImpl.getStats() async to fetch cache stats from strategies
- Update factory test to expect cache instance
Enables monitoring of cache evictions and rate limiting events.
* fix(test): correct LRU eviction test to avoid duplicate identifier access
Changed test to access token-3 instead of token-1 twice to properly verify
LRU eviction behavior. Now expects token-1 (oldest) to be evicted instead
of token-2.
* feat(ocpp2): extend mock server for auth testing scenarios
Add configurable authorization behavior to OCPP 2.0 mock server:
- Whitelist/blacklist mode for token validation
- Offline mode simulation (network failure)
- Rate limiting simulation (NotAtThisTime responses)
- Pre-authorization for remote start transactions
- CLI arguments for runtime configuration
This enables comprehensive testing of:
- G03.FR.02 (offline authorization)
- G03.FR.03 (remote start pre-authorization)
- G03.FR.04 (whitelist/blacklist management)
* test(ocpp2): add G03.FR.02 offline authorization tests
Add 9 tests for OCPP 2.0 offline authorization scenarios:
G03.FR.02.001 - Offline detection (3 tests):
- Detect station offline when not in accepted state
- Detect station online when in accepted state
- Verify correct OCPP version
G03.FR.02.002 - Remote availability check (2 tests):
- Return false when offline even with valid config
- Handle errors gracefully when checking availability
G03.FR.02.003 - Configuration validation (3 tests):
- Initialize with default configuration
- Validate configuration schema for offline auth
- Monitor offline state via getStatus method
These tests verify the adapter correctly detects offline
state and reports availability for fallback to LocalAuthStrategy.
* test: add G03.FR.03 Remote Start Pre-Authorization tests for OCPP 2.0
- Implement 20 unit tests for RequestStartTransaction with pre-authorization
- Cover successful remote start with valid token (G03.FR.03.001)
- Cover remote start rejected with blocked token (G03.FR.03.002)
- Cover remote start with group token validation (G03.FR.03.003)
- Cover remote start without EVSE ID error cases (G03.FR.03.004)
- Cover remote start on occupied connector (G03.FR.03.005)
- Cover remote start with charging profile (G03.FR.03.006)
- Add request validation checks (G03.FR.03.007)
- Add service initialization tests (G03.FR.03.008)
- All tests validate OCPP 2.0.1 data structures
- Update task completion tracking (Phase 2.2: 67% complete)
Effort: 2.5j | Tests: 20 | Status: ✅ All passing
* docs: update task completion checklist - Phase 2.2 complete
- Mark G03.FR.03 remote start tests complete (20 tests)
- Document G03.FR.04 blocker (SendLocalList not implemented)
- Update Phase 2 completion: 94% (25.5j/27j)
- Total progress: 43j/74j (58%)
Phase 2.2 pragmatically complete with gaps documented.

* [autofix.ci] apply automated fixes
* fix(test): correct parameter order in TransactionEvent context-aware tests
* [autofix.ci] apply automated fixes
* fix(ocpp2.0): correct sendTransactionEvent argument order in RequestStartTransaction
- Fix argument order in handleRequestStartTransaction: context must be 3rd arg
- Update E01/E02 tests to use async dynamic import for auth mock injection
- Remove debug console.log statements from test files
The sendTransactionEvent call had incorrect argument order causing auth to fail
with 'Rejected' status. Fixed to match function signature:
(station, eventType, context, connectorId, transactionId)
* fix(test): resolve lint errors in E01/E02 mock auth services
- Remove unused AuthorizationStatus import
- Change async methods to Promise.resolve pattern to fix require-await lint rule
* [autofix.ci] apply automated fixes
* test(ocpp2.0): harmonize test names and add FR comments per OCPP 2.0.1 spec
- Rename E01/E02 test suites to F01/F02/F03/F04 per OCPP 2.0.1 Part 6 test cases
- Add functional requirement (FR) references to test cases
- RequestStartTransaction: F01.FR.03-19, F02.FR.01
- RequestStopTransaction: F03.FR.02-09, F04.FR.01
* refactor(test): extract createMockAuthService to shared MockFactories
- Move duplicated mock auth service factory to shared MockFactories.ts
- Update RequestStartTransaction and RequestStopTransaction tests to use shared import
- Reduces code duplication per DRY principle
* feat(ocpp): include remoteStartId, idToken, and meterValue in TransactionEvent
Implement OCPP 2.0.1 spec requirements:
- F01.FR.17: Include remoteStartId in TransactionEvent(Started)
- F02.FR.05: Include idToken in TransactionEvent(Started)
- F03.FR.09: Include final meter values in TransactionEvent(Ended)
* refactor(test): harmonize OCPP 2.0 tests - ESLint headers, FR refs, async patterns
* refactor(ocpp): remove inline copyright headers for REUSE compliance
Remove inconsistent inline copyright headers from 12 OCPP source files.
Copyright attribution is now centralized via REUSE/SPDX approach.
Files cleaned:
- 1.6: OCPP16RequestService, OCPP16ServiceUtils, OCPP16ResponseService,
OCPP16IncomingRequestService
- 2.0: OCPP20ResponseService, OCPP20RequestService, OCPP20VariableManager,
OCPP20ServiceUtils, OCPP20IncomingRequestService
- auth: CertificateAuthStrategy, OCPPAuthServiceImpl, factories/index
* chore(ocpp): remove vague TODO comment
* fix(ocpp): add ChargingRateChanged to TriggerReasonMapping
* fix(test): resolve floating promise lint errors in OCPP 2.0 tests
* fix(test): mock OCPP 2.0 service dependencies in auth adapter tests
Mock isRemoteAvailable and sendTransactionEvent to avoid singleton
dependency issues that cause test failures on Windows CI environment.
The OCPP20VariableManager singleton behaves differently across platforms,
and mocking isolates unit tests from runtime dependencies.
* [autofix.ci] apply automated fixes
* chore: remove .sisyphus working directory from repository
* fix(auth): use typed errors and strict types per review
* docs(auth): improve JSDoc and add OCPP 2.0.1 transaction tracking types
* test(auth): add assertion helpers and afterEach cleanup hooks
* fix(ocpp): reset all transaction state in resetTransactionSequenceNumber
Ensure transactionEvseSent and transactionIdTokenSent are reset
alongside transactionSeqNo to prevent test order dependencies
across platforms (fixes Windows CI failures).
* docs: mark RequestStopTransaction and TransactionEvent as implemented
* refactor(ocpp): remove deprecated TransactionEvent wrapper methods
* fix(ocpp): relax transactionId validation and strengthen ChargingProfile validation
- Add validateIdentifierString() for OCPP 2.0.1 identifier validation
- Accept non-empty string ≤36 chars for transactionId (UUID is RECOMMENDED)
- Enforce TxProfile purpose for RequestStartTransaction (OCPP 2.0.1 §2.10)
- Reject chargingProfile.transactionId in RequestStartTransaction
- Add comprehensive unit tests for new validation logic
* feat(ocpp): add periodic TransactionEvent at TxUpdatedInterval (OCPP 2.0.1 E02.FR.09/10)
Implements periodic transaction event transmission at configurable TxUpdatedInterval:
- Add transactionTxUpdatedSetInterval field to ConnectorStatus type
- Implement startTxUpdatedInterval() and stopTxUpdatedInterval() methods
- Export OCPP20TransactionEventEnumType and OCPP20TriggerReasonEnumType
- Export OCPP20ServiceUtils from ocpp/index.ts
- Timer lifecycle: starts on RequestStartTransaction
- Timer cleanup: stops on RequestStopTransaction
- OCPP 2.0 only, guards prevent 1.6 activation
- Safely handles null/undefined connectors and intervals
- Follows E02.FR.09/10 specification
All tests passing (121/121), lint passing, build successful.
* feat(ocpp): queue TransactionEvents with seqNo on offline (OCPP 2.0.1 offline-first)
* test(ocpp2): add tests for TxUpdatedInterval periodic timer and offline queueing
- Add comprehensive tests for TxUpdatedInterval timer lifecycle (start/stop)
- Test MeterValuePeriodic trigger reason for periodic TransactionEvents
- Verify seqNo increment across periodic events
- Test independent timers per connector
- Add offline queueing tests for WebSocket disconnection scenarios
- Test seqNo preservation in queued events
- Verify FIFO queue drain order on reconnection
- Test seqNo continuity across online→offline→online transitions
- Test independent queues per connector
* refactor(test): harmonize test code with codebase conventions
- Remove unnecessary eslint-disable camelcase directive
- Fix unused parameter warning with underscore prefix
- Rename variables from snake_case to camelCase
* fix(test): use setInstanceForTesting for cross-platform mock injection
Add setInstanceForTesting() method to OCPPAuthServiceFactory to allow
tests to inject mock auth services without relying on ESM module
internals. This fixes Windows CI failures caused by ESM module caching
differences between platforms.
Changes:
- Add OCPPAuthServiceFactory.setInstanceForTesting() static method
- Update createMockAuthService() to return proper OCPPAuthService type
- Update RequestStartTransaction tests to use new method
- Update RequestStopTransaction tests to use new method
- Remove dynamic import workarounds that failed on Windows
* fix(tests): add missing mock methods and globalThis sharing for auth factory
- Add globalThis-based instance sharing to OCPPAuthServiceFactory
Required for cross-module mock injection with dynamic imports
- Add missing mock methods to ChargingStationFactory:
- isWebSocketConnectionOpened() - prevents offline queueing in tests
- getNumberOfEvses() - required for EVSE validation
- startTxUpdatedInterval() / stopTxUpdatedInterval() - for timer tests
- Remove redundant null check in validateChargingProfile()
TypeScript types guarantee id and stackLevel are always present
* fix(tests): correct transaction ID validation test to match actual implementation
The test incorrectly expected UUID format validation, but the actual
OCPP 2.0.1 spec and implementation only validates identifier strings
(non-empty, ≤36 characters). Updated test to use a >36 char string and
expect the correct error message.
* fix(ocpp2): exclude transactionTxUpdatedSetInterval and transactionEventQueue from serialization
The new connector status fields transactionTxUpdatedSetInterval (NodeJS.Timeout)
and transactionEventQueue (runtime queue) cannot be serialized to JSON and must
be excluded when saving charging station configuration.
* [autofix.ci] apply automated fixes

fix: ensure proper cleanup of BroadcastChannel resources in AbstractUIService tests
Add service.stop() calls to all AbstractUIService tests to properly close
BroadcastChannel instances. On Windows, unclosed BroadcastChannel handles
can cause test freezes due to unfreed system resources. This ensures proper
cleanup after each test completes.
