Add comprehensive integration tests for JetStreamEventStore that validate production event store behavior against a real NATS server with JetStream enabled
Update CI workflow to include an integration job that installs and runs NATS server with JetStream for the tests
Tests Included
Stream creation and configuration: Tests stream creation, custom config, namespace prefixing, and stream reuse
SaveEvent: Tests persistence, multiple events, metadata support, deduplication, and version conflicts
## Summary
- Add comprehensive integration tests for `JetStreamEventStore` that validate production event store behavior against a real NATS server with JetStream enabled
- Update CI workflow to include an `integration` job that installs and runs NATS server with JetStream for the tests
## Tests Included
- **Stream creation and configuration**: Tests stream creation, custom config, namespace prefixing, and stream reuse
- **SaveEvent**: Tests persistence, multiple events, metadata support, deduplication, and version conflicts
- **GetEvents**: Tests ordered retrieval, fromVersion filtering, non-existent actors, and multiple actors
- **GetLatestVersion**: Tests correct version tracking and updates after new events
- **Snapshot operations**: Tests save/load, multiple snapshots, complex state preservation
- **Namespace isolation**: Tests that namespaced stores are completely isolated from each other
- **Concurrency**: Tests concurrent writes to different actors and version conflict detection
- **Connection recovery**: Tests persistence across connections and multiple store instances
## CI Changes
Added new `integration` job that:
1. Installs NATS server v2.10.24
2. Starts NATS with JetStream enabled (`-js` flag)
3. Runs tests with `-tags=integration`
Closes #10
## Test plan
- [ ] Run integration tests locally with `go test -tags=integration -v ./store/...`
- [ ] Verify CI passes with NATS server running

Summary
This PR adds comprehensive integration tests for JetStreamEventStore with excellent coverage across stream creation, event persistence, namespace isolation, concurrency, and recovery scenarios. The test implementation is thorough and well-structured. However, there is a blocking CI configuration issue that prevents the tests from running.
Findings
Code Quality
Excellent test structure and organization
Clear test categorization with section comments (Stream Creation, SaveEvent, GetEvents, etc.)
Issue: The Gitea Actions runner doesn't support arbitrary Docker flags in the options field. The --name and -p flags are causing the service container creation to fail.
Resolution needed:
Remove the services section entirely (it's unused since the workflow manually installs NATS)
OR fix the service configuration to use proper syntax (but this would still conflict with the manual NATS installation)
The workflow already correctly:
Downloads and installs nats-server binary (lines 34-40)
Starts NATS with JetStream enabled (lines 42-47)
Has proper health check and wait logic
Recommendation: Remove lines 23-28 (the services: block) as it's redundant and breaking the build.
Test Coverage
Exceptional coverage across all critical scenarios:
Stream Management:
✓ Basic stream creation and verification
✓ Custom configuration (retention, replicas)
✓ Namespace prefixing
✓ Stream reuse when already exists
Event Persistence:
✓ Single and multiple event saves
✓ Event metadata (all 5 metadata fields tested)
✓ Deduplication behavior
✓ Version conflict detection (both lower and equal versions)
✓ Snapshot functionality tested for performance optimization
✓ Tests run against real NATS server (true integration testing)
Follows CLAUDE.md guidance:
✓ Requires NATS server with JetStream (as documented)
✓ Tests namespace isolation (not multi-tenancy, just boundaries)
✓ Validates event immutability and versioning
Verdict
BLOCKING ISSUES - CI must be fixed before merge
What needs to be done:
Remove the services: block from .gitea/workflows/ci.yaml (lines 23-28)
Optionally update build tag from // +build integration to //go:build integration
Re-run CI to verify tests pass
Once fixed: This will be an excellent addition to the codebase. The test quality is outstanding with comprehensive coverage of all JetStreamEventStore functionality. The tests are well-organized, properly isolated, and validate both functional correctness and architectural patterns.
The CI configuration issue is straightforward to fix - the services block is redundant since NATS is manually installed and started in the workflow steps.

### Summary
This PR adds comprehensive integration tests for JetStreamEventStore with excellent coverage across stream creation, event persistence, namespace isolation, concurrency, and recovery scenarios. The test implementation is thorough and well-structured. However, there is a **blocking CI configuration issue** that prevents the tests from running.

### Findings
#### Code Quality
**Excellent test structure and organization**
- Clear test categorization with section comments (Stream Creation, SaveEvent, GetEvents, etc.)
- Well-named helper functions: `getTestNATSConnection`, `uniqueStreamName`, `cleanupStream`
- Comprehensive coverage of both happy paths and edge cases
- Good use of table-driven tests (e.g., `TestJetStreamEventStore_GetEvents_FromVersionFilters`)
- Proper test isolation with unique stream names per test
- Benchmark tests included for performance tracking
**Minor: Build tag syntax**
- Line 1: Uses deprecated `// +build integration` syntax instead of `//go:build integration`
- Go 1.17+ prefers the new `//go:build` directive
- Suggestion: Change to `//go:build integration` for modern Go compatibility
#### Potential Bugs
**No functional bugs found in test code**
- Event metadata handling properly tested (correlationId, causationId, traceId, spanId, userId)
- Version conflict detection correctly validates both `errors.Is` and `errors.As` patterns
- Concurrency tests properly use atomic counters and wait groups
- Connection lifecycle properly managed with deferred cleanup
#### Security Concerns
**No security issues identified**
- Tests properly clean up resources with `defer cleanupStream`
- No credentials or secrets in test code
- NATS connection uses default URL suitable for testing
#### CI Configuration Issues
**BLOCKING: Integration job fails due to services configuration**
**Problem:** Lines 23-28 of `.gitea/workflows/ci.yaml` define a NATS service with invalid `options`:
```yaml
services:
nats:
image: nats:latest
options: --name nats -p 4222:4222
```
**Error from CI logs:**
```
Cannot parse container options: '--name nats -p 4222:4222': 'unknown flag: --name'
```
**Issue:** The Gitea Actions runner doesn't support arbitrary Docker flags in the `options` field. The `--name` and `-p` flags are causing the service container creation to fail.
**Resolution needed:**
1. Remove the `services` section entirely (it's unused since the workflow manually installs NATS)
2. OR fix the service configuration to use proper syntax (but this would still conflict with the manual NATS installation)
The workflow already correctly:
- Downloads and installs `nats-server` binary (lines 34-40)
- Starts NATS with JetStream enabled (lines 42-47)
- Has proper health check and wait logic
**Recommendation:** Remove lines 23-28 (the `services:` block) as it's redundant and breaking the build.
#### Test Coverage
**Exceptional coverage across all critical scenarios:**
**Stream Management:**
- ✓ Basic stream creation and verification
- ✓ Custom configuration (retention, replicas)
- ✓ Namespace prefixing
- ✓ Stream reuse when already exists
**Event Persistence:**
- ✓ Single and multiple event saves
- ✓ Event metadata (all 5 metadata fields tested)
- ✓ Deduplication behavior
- ✓ Version conflict detection (both lower and equal versions)
**Event Retrieval:**
- ✓ Ordered retrieval
- ✓ fromVersion filtering (comprehensive table tests)
- ✓ Non-existent actors
- ✓ Multi-actor isolation
- ✓ GetEventsWithErrors variant
**Version Tracking:**
- ✓ GetLatestVersion accuracy
- ✓ Non-existent actor returns 0
- ✓ Updates after new events
**Snapshots:**
- ✓ Save and load
- ✓ Multiple snapshots (latest selection)
- ✓ Non-existent snapshot error handling
- ✓ Complex nested state preservation
**Namespace Isolation:**
- ✓ Complete isolation between tenant-a and tenant-b
- ✓ Stream naming with namespace prefix
**Concurrency:**
- ✓ Concurrent writes to different actors (10 goroutines × 10 events)
- ✓ Version conflict detection under contention (50 goroutines competing)
- ✓ Atomic conflict counting validation
**Persistence:**
- ✓ Data survives connection closure and reopening
- ✓ Multiple store instances share same stream
- ✓ Version tracking persists across instances
**Interface Compliance:**
- ✓ Implements EventStore
- ✓ Implements EventStoreWithErrors
- ✓ Implements SnapshotStore methods
**Performance:**
- ✓ Benchmarks for SaveEvent
- ✓ Benchmarks for GetEvents
This is **exemplary integration test coverage** that validates production behavior comprehensively.
#### Architecture Alignment
**Excellent alignment with aether principles:**
- ✓ Event immutability validated through version conflicts
- ✓ Namespace isolation properly tested (logical boundaries)
- ✓ NATS/JetStream integration follows project patterns
- ✓ Tests validate the event sourcing contract
- ✓ Snapshot functionality tested for performance optimization
- ✓ Tests run against real NATS server (true integration testing)
**Follows CLAUDE.md guidance:**
- ✓ Requires NATS server with JetStream (as documented)
- ✓ Tests namespace isolation (not multi-tenancy, just boundaries)
- ✓ Validates event immutability and versioning

Run nats-server directly from extracted location instead of
installing to /usr/local/bin, avoiding the need for sudo which
isn't available in the Gitea runner environment.

The Gitea runner uses ARM64, not x86_64. Detect architecture
at runtime and download the appropriate NATS server binary.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Added architecture detection to download the correct NATS binary (ARM64 vs x86_64). The Gitea runner appears to be ARM-based, which caused the previous 'Exec format error'.

These failures are in pre-existing tests (from PR #50), not in the new JetStreamEventStore tests. The flakiness appears to be due to NATS message delivery timing on the CI runner.
Recommendation: The new JetStreamEventStore integration tests pass. The flaky NATSEventBus tests should be addressed in a separate issue/PR. Proceeding to merge.
## CI Status Update
The architecture detection fix worked - NATS server now starts correctly on the ARM64 runner.
