# Task: Adjust testGetCheckinDataByQwStaff Test Method

## Plan

- [ ] Add validation for the 30-day time span restriction
- [ ] Add logging to show batch processing when user count exceeds 100
- [ ] Add validation to ensure time range doesn't exceed 30 days
- [ ] Improve comments to clearly document all 5 interface restrictions

## Interface Restrictions (from Enterprise WeChat API)
1. Time span must not exceed 30 days
2. User list must not exceed 100 (batch processing required if more)
3. (Missing #3 in original comments)
4. Standard check-in time only valid for fixed and custom schedules
5. API call frequency limit: 600 times/minute

## Current Implementation Status
- ✓ Service layer (`getCheckinData`) already implements 100-user batching
- ✓ Service layer already has 500ms delay between batches (rate limiting)
- ✗ Test method doesn't validate 30-day restriction
- ✗ Test method doesn't show batch processing information

## Changes Needed
1. Add time span validation (ensure endTime - startTime <= 30 days)
2. Add logging to show total user count and batch information
3. Update comments to be more complete and clear

## Review

### Changes Made
1. **Added 30-day time span validation** - The test now validates that the time range doesn't exceed 30 days and exits early if it does
2. **Added batch processing information** - Shows total user count and calculates how many batches will be processed when users exceed 100
3. **Improved comments** - Added complete documentation of all 5 interface restrictions with notes about what's already handled in the Service layer

### Key Improvements
- Time span validation with clear error message
- User count and batch information displayed before API call
- Complete interface restriction documentation (added missing #3: max 3000 records)
- Notes indicating Service layer already handles batching and rate limiting

### Code Impact
- Minimal changes to test method only
- No changes to service layer (already correctly implemented)
- Added validation and logging for better visibility
- Test now clearly demonstrates compliance with API restrictions
