# Test Script for Admin Interventions Endpoints (BE-001)
#
# Purpose: Test student intervention alerts management endpoints
# Target: Admin Portal - Student Intervention Alerts System
#
# Endpoints Tested:
#   GET    /admin/interventions - List all alerts with filters
#   GET    /admin/interventions/:id - Get specific alert
#   PATCH  /admin/interventions/:id/acknowledge - Acknowledge alert
#   PATCH  /admin/interventions/:id/resolve - Resolve alert
#   DELETE /admin/interventions/:id/dismiss - Dismiss alert
#
# Prerequisites:
#   - Backend running on http://localhost:3000
#   - Valid JWT token with SUPER_ADMIN or ADMIN_TEACHER role
#   - Database with student_intervention_alerts table populated
#
# Usage:
#   ./test-interventions-endpoints.sh <JWT_TOKEN>
