# E2E Integration Testing for Landing Feature
# =============================================================================
#
# Full stack E2E testing with database, backend API, and frontend.
# Database is seeded, migrations run, tests execute, then everything tears down.
#
# Usage:
#   docker compose -f docker-compose.e2e.yml up --build --abort-on-container-exit
#   docker compose -f docker-compose.e2e.yml down -v
#
# Note: NPM_REGISTRY defaults to http://npm.black.lan/

  # Examples:
  #   E2E_GREP="checkout" docker compose -f docker-compose.e2e.yml up --build
  #   E2E_FILE="e2e/tests/votes/" docker compose -f docker-compose.e2e.yml up --build
