# League Settings Integration Tests

## Overview

This directory contains integration tests for league settings features. The tests are written using Vitest and cover the following functionality:

### Team Management
- **Remove Team Owner**: Commissioners can remove owners from teams
- **Assign Team Owner**: Admins can assign users to teams via dropdown
- **Authorization**: Proper access control for commissioners vs admins
- **Edge Cases**: Handling invalid inputs and error scenarios
- **Integration Scenarios**: Complete workflows and multi-team operations

### Draft Reset
- **Admin-Only Access**: Only admins can reset drafts
- **Delete Operations**: Clearing picks and queues
- **Status Updates**: Resetting season to pre_draft
- **Draft Order Preservation**: Ensuring draft slots remain intact
- **Data Integrity**: Maintaining referential integrity during reset

## Key Features Tested

### Commissioner Capabilities
- Remove owners from any team in their league
- No ability to assign owners (admin-only)

### Admin Capabilities
- Remove owners from any team
- Assign any user to any team via dropdown
- Access to full user list for assignment
- **Reset draft** (admin-only, not commissioners)
  - Delete all draft picks
  - Clear all draft queues
  - Reset season to pre_draft status
  - Preserve draft order

### Security
- Admin-only check enforced for assignments and draft resets
- Commissioner access verified for removals
- Proper error handling for unauthorized access
- Status validation for draft reset operations

## Mocking Strategy

The tests use Vitest's mocking capabilities to:
- Mock database operations (`removeTeamOwner`, `assignTeamOwner`)
- Mock user authentication (`isUserAdminByClerkId`)
- Mock user data fetching (`findAllUsers`)
- Simulate various success and error scenarios

## Future Enhancements

Potential additions to the test suite:
- [ ] Test UI component rendering
- [ ] Test form validation
- [ ] Test loading states
- [ ] Test success/error toast messages
- [ ] Test concurrent operations
- [ ] Test with real database (integration tests)
- [ ] Performance tests for large user lists
