# APScheduler Test Plan

## Overview

This document outlines a comprehensive test plan to verify APScheduler functionality and visibility in the Lin application. The plan includes both automated tests and manual verification steps.

## Test Objectives

1. **Verify APScheduler is properly initialized** during application startup
2. **Confirm logging configuration** shows APScheduler messages
3. **Test schedule loading functionality** from the database
4. **Verify job creation and execution** mechanisms
5. **Ensure scheduler persistence** and error handling

## Test Environment Setup

### Prerequisites
- Python 3.8+ installed
- All dependencies from `backend/requirements.txt` installed
- Environment variables configured (Supabase credentials, etc.)
- Access to the Lin application source code

### Test Files to Create

#### 1. `test_scheduler_visibility.py`
**Purpose**: Standalone test script to verify APScheduler logging and basic functionality

```python
#!/usr/bin/env python3
"""
Test script for APScheduler visibility and functionality.
This script tests whether APScheduler is working and properly configured for logging.

```

## Manual Verification Steps

### 1. Check Application Startup Logs
After implementing the logging configuration, start your application and look for:
- `Initializing APScheduler...`
- `BackgroundScheduler created`
- `Scheduler started`
- `Adding periodic job to load schedules...`
- `Schedule loading job added (runs every 5 minutes)`

### 2. Verify Scheduler Functionality
1. Create a schedule via the API
2. Check logs for schedule loading messages
3. Verify that individual jobs are created
4. Monitor for job execution at scheduled times

### 3. Test Error Handling
1. Test with invalid Supabase credentials
2. Test with missing environment variables
3. Verify appropriate error messages are logged

## Troubleshooting Guide

### Common Issues and Solutions

#### Issue 1: No APScheduler messages in logs
**Solution**: Ensure logging configuration is added to `backend/app.py`:
```python
import logging
logging.basicConfig(level=logging.DEBUG)
logging.getLogger('apscheduler').setLevel(logging.DEBUG)
```

#### Issue 2: Scheduler initialization fails
**Solution**: Check environment variables and Supabase connection:
- Verify `SUPABASE_URL` and `SUPABASE_KEY` are set
- Check network connectivity to Supabase
- Verify database tables exist

#### Issue 3: Jobs not executing
**Solution**: 
- Check that the application is running continuously
- Verify job triggers are correctly configured
- Check for any exceptions in job execution

#### Issue 4: Test script fails
**Solution**:
- Ensure all dependencies are installed
- Check Python path includes the backend directory
- Verify mock data structure matches actual database schema

## Success Criteria

The APScheduler implementation is considered successful when:

1. ✅ **Startup logs** show APScheduler initialization messages
2. ✅ **Test scripts** pass all tests
3. ✅ **Integration test** shows scheduler working in Flask app
4. ✅ **Manual verification** confirms job creation and execution
5. ✅ **Error handling** works appropriately
6. ✅ **Documentation** is updated with troubleshooting guide

## Next Steps

1. **Approve this test plan**
2. **Switch to Code mode** to implement the logging configuration
3. **Create the test scripts** outlined in this plan
4. **Execute the tests** to verify APScheduler visibility
5. **Update documentation** with the final solution
