compose.test.yml

# TryPost: dedicated local Postgres for the test suite (host-run PHP, no Docker app container).
#
# This is intentionally separate from compose.yaml (the full Docker dev stack).
# compose.yaml's pgsql service is meant to run alongside the Dockerized app
# service and already occupies host port 5432 by default. On a machine where
# 5432 is taken by another project's container, this file gives the test
# suite its own isolated Postgres on a different port, without touching the
# main dev compose setup.
#
# Start: docker compose -f compose.test.yml -p trypost-test up -d
# Wait:  docker compose -f compose.test.yml -p trypost-test exec pgsql-test pg_isready -U postgres -d trypost
# Stop:  docker compose -f compose.test.yml -p trypost-test down
# Reset: docker compose -f compose.test.yml -p trypost-test down -v (drops the named volume, fresh DB next start)
#
# See .env.testing and phpunit.xml for the matching DB_HOST/DB_PORT/DB_DATABASE/
# DB_USERNAME/DB_PASSWORD values, and docs/testing.md for the full write up.
