error-boundary-test.sh

#!/bin/bash
# Frontend error boundary & resilience testing — wraps the existing Playwright
# error-resilience spec with additional validation of error boundary behavior.
#
# Usage:
#   ./scripts/error-boundary-test.sh              # Run error resilience tests
#
# Prerequisites:
#   - Node.js and npm installed
#   - npm install done in web/
#   - Frontend running at localhost:5174 (or PLAYWRIGHT_BASE_URL set)
#
# Output:
#   /tmp/error-boundary-report.json    — JSON test results
#   /tmp/error-boundary-summary.md     — human-readable summary
#
# Exit code:
#   0 — all tests pass
#   1 — one or more tests failed
