# Goal-6-Task-1 Test Plan

## Test Objectives
Verify Scheduled Task System Core meets all requirements:
1. Cron-like scheduling with ±1s accuracy
2. AES-256 encryption compliance  
3. Integration with dispatcher system
4. Modularity (file size ≤ 500 lines)
5. Test coverage ≥ 95%

## Test Cases

### 1. Scheduling Accuracy
- [ ] Verify task execution within ±1s of scheduled time
- [ ] Test various cron expressions (* * * * *, */5 * * * *, etc.)
- [ ] Verify handling of daylight savings time changes

### 2. Security Compliance
- [ ] Verify AES-256 encryption for task payloads
- [ ] Validate encryption key management
- [ ] Test secure task serialization

### 3. Dispatcher Integration
- [ ] Verify task execution triggers dispatcher
- [ ] Test error handling when dispatcher unavailable
- [ ] Validate task status updates

### 4. Modularity
- [ ] Verify scheduler.py ≤ 500 lines
- [ ] Check separation of concerns
- [ ] Validate dependency management

### 5. Test Coverage
- [ ] Review existing test cases
- [ ] Identify missing coverage areas
- [ ] Verify ≥ 95% coverage

## Test Environment
- Python 3.10+
- pytest framework
- Local development environment

## Test Data
- Sample cron expressions
- Test tasks with various payloads
- Mock dispatcher responses

## Risks
- Timing tests may be flaky
- Encryption tests require valid keys
- Dispatcher integration requires running service
