…Serviceconnection wiring + bump v26.06.31 Wave 4 (final) — Spring @Testcontainers/@Serviceconnection equivalent in pyfly.testing.testcontainers: - Container factories (postgres/mysql/redis/mongodb/kafka) wrapping testcontainers (new optional extra pyfly[testcontainers]; lazy import + clear install hint). - pyfly_config_for(container) maps a started container to pyfly config keys (Postgres/MySQL->async relational.url, Redis->cache+session redis.url, Mongo->document.uri, Kafka->eda.kafka.bootstrap-servers); pyfly_config(*containers) builds a Config. - is_docker_available() + @requires_docker skip integration tests cleanly when Docker absent. Tests: tests/testing/test_testcontainers.py (10: mappings via fakes, nesting, docker-availability, extra-absent error, requires_docker skip). Gates: mypy --strict (614), ruff + format, full suite 3786 passed (+graceful skip).
CI runs --all-extras (testcontainers installed) on Docker-enabled runners, so the 'extra absent' + 'skips without docker' assumptions failed there. Replace with: - _load() against a nonexistent submodule -> RuntimeError install hint (works whether or not the extra is installed); - inspect that @requires_docker attaches a skipif mark (works whether or not Docker is up). Verified passing with testcontainers both absent and installed.
