From 28ea61815e1b9a563150b4ff1d7011a436fbfe80 Mon Sep 17 00:00:00 2001 From: HenryNebula <22852427+HenryNebula@users.noreply.github.com> Date: Wed, 6 May 2026 08:20:52 -0400 Subject: [PATCH 01/10] refactor: split monolithic test_integration.py into per-driver files Extract each DB driver test class into its own module (test_hsqldb, test_postgres, test_mysql, test_mssql, test_trino, test_oracle, test_db2, test_drill, test_sqlite) and consolidate duplicated infrastructure tests (fork safety, JAR path spaces, dynamic classpath, JPype reflection) into test_infrastructure.py using parameterized base classes. This fixes a CI gap where infrastructure tests were never included in any tox environment. Shared test methods live in test/_base.py (IntegrationTestBase).

Tests use this to suppress noisy Java loggers (slf4j-simple and java.util.logging) via a bundled logging.properties file, keeping the library itself opinion-free. Also moves 12 HSQLDB-specific tests into the shared IntegrationTestBase and adds skip overrides for Drill/Trino on INSERT-dependent tests.
