# Work Summary: Notification Repository Tests
|
|
|
|
**Date**: January 15, 2026 (Late Evening)
|
|
**Focus**: Comprehensive integration test coverage for Notification repository
|
|
**Status**: ✅ Complete - All tests passing
|
|
|
|
---
|
|
|
|
## Overview
|
|
|
|
Implemented comprehensive integration tests for the Notification repository, bringing total project test count to **470 passing tests** (up from 429). This completes test coverage for 12 of 14 core repositories.
|
|
|
|
---
|
|
|
|
## Changes Made
|
|
|
|
### 1. Repository Schema Fix
|
|
|
|
**Issue**: Notification repository was using incorrect table name
|
|
- **Before**: Using `notifications` without schema prefix
|
|
- **After**: Using `attune.notification` (matches migration)
|
|
- **Impact**: All queries now work correctly with schema-prefixed table
|
|
|
|
**Files Modified**:
|
|
- `crates/common/src/repositories/notification.rs` - Fixed all SQL queries
|
|
|
|
### 2. Notification Repository Tests
|
|
|
|
**New File**: `crates/common/tests/notification_repository_tests.rs`
|
|
|
|

## Technical Details
|
|
|
|
### Notification Schema
|
|
```sql
|
|
CREATE TABLE attune.notification (
|
|
id BIGSERIAL PRIMARY KEY,
|
|
channel TEXT NOT NULL,
|
|
entity_type TEXT NOT NULL,
|
|
entity TEXT NOT NULL,
|
|
activity TEXT NOT NULL,
|
|
state notification_status_enum NOT NULL DEFAULT 'created',
|
|
content JSONB,
|
|
created TIMESTAMPTZ NOT NULL DEFAULT NOW(),
|
|
updated TIMESTAMPTZ NOT NULL DEFAULT NOW()
|
|
);
|
|
```
|
|
|
|
### Notification States
|
|
- `Created` - Initial state when notification is created
|
|
- `Queued` - Notification queued for delivery
|
|
- `Processing` - Notification is being delivered
|
|
- `Error` - Notification delivery failed
|
|
|
|
### PostgreSQL pg_notify Integration
|
|
The notification table has a trigger that automatically sends PostgreSQL NOTIFY events when notifications are inserted. This enables real-time updates via the Notifier service.
|
|
|
|
**Channel Length Limit**: PostgreSQL `pg_notify` limits channel names to 63 characters. Tests validate this constraint.
|
|
|

|
|
|
|
## Key Insights
|
|
|
|
### 1. Schema Consistency
|
|
Following the pattern from other repositories, all tables should use the `attune.` schema prefix explicitly in queries.
|
|
|
|
### 2. JSON Content Flexibility
|
|
The `content` JSONB field supports:
|
|
- Objects `{"key": "value"}`
|
|
- Arrays `[1, 2, 3]`
|
|
- Primitives `"string"`, `42`, `true`, `null`
|
|
- Complex nested structures
|
|
|
|
### 3. PostgreSQL NOTIFY Constraints
|
|
- Channel names limited to 63 characters
|
|
- Tests must account for this when generating unique channel names
|
|
- Payload is JSON-encoded notification metadata
|
|
|
|
### 4. State Transitions
|
|
No database constraints enforce valid state transitions. Application logic should handle:
|
|
- Created → Queued → Processing → (success or Error)
|
|
- Ability to update content when transitioning to Error state
|
|

## Next Steps
|
|
|
|
### Immediate (Next Session)

|
|
|
|
### Medium-Term
|
|
1. **Executor Service Implementation** - All dependencies now tested
|
|
2. **Worker Service Implementation** - Runtime and worker repos need tests first
|
|
3. **End-to-End Integration Tests** - Full automation flow testing
|
|
|
|
### Long-Term
|
|
1. **Sensor Service Implementation**
|
|
2. **Notifier Service Implementation**
|
|
3. **Performance Testing** - Load testing with high notification volumes
|
|
4. **Production Readiness** - Security, monitoring, deployment
|
|

|
|
## Lessons Learned
|
|
|
|
1. **Schema Prefix Consistency** - Always use `attune.` schema prefix in all queries
|
|
2. **PostgreSQL Limits** - Be aware of system limits (channel names, etc.)
|
|
3. **Test Fixtures** - Well-designed fixtures accelerate test development
|
|
4. **Parallel Safety** - Atomic counters + unique IDs = reliable parallel tests
|
|
5. **JSON Testing** - Test all JSON value types, not just objects
|

## Conclusion
|
|
|
|
The Notification repository now has comprehensive test coverage matching the quality and thoroughness of other repositories in the project. With 86% of core repositories tested and 470 tests passing, the Attune project has a solid foundation for implementing the remaining services (Executor, Worker, Sensor, Notifier).

|
|
|
**Status**: ✅ Ready to begin Executor service implementation |
