# Runs the test suite against a real MySQL database, inside the app container.
#
#   scripts/run_tests.sh              # rebuild the test DB, then run everything
#   scripts/run_tests.sh --no-rebuild # skip the rebuild (faster, if schema is unchanged)
#   scripts/run_tests.sh --filter AuthTest
#
# Why root: the test database (axioma_test) is disposable and created fresh by
# `artisan test:prepare-db`, but the app's own MySQL user only has rights on
# the real `axioma` database, so it cannot see — let alone create — the test
# one. Granting it rights on a throwaway database would be more moving parts
# than just using the credentials that already exist. Read from the repo's own
# root .env, same as scripts/backup_db.sh.
#
# The unit tests don't need any of this (they extend PHPUnit's TestCase
# directly and never touch a database); this exists for the feature tests.
