Companion code for Top 40 Hibernate and JPA Interview Questions (2026) with Runnable Answers on ankurm.com.

One test per question (src/test/java/lab/hibernate/A_...F_*). Each test writes its own transcript to output/qNN-*.txt and asserts the same facts, so an answer in the article that stops being true fails the build.

Component	Version
Hibernate ORM	7.4.13.Final
PostgreSQL	16.15 (server), pgjdbc 42.7.14
JUnit	6.1.3
JDK	25.0.5

./scripts/start-postgres.sh   # throwaway PostgreSQL on :5433 (or point LAB_DB_URL at your own)
./scripts/run-all.sh          # runs 40 tests, rewrites output/

The test JVM runs with -Duser.timezone=UTC (see pom.xml): a PostgreSQL build without a complete tz database rejects some JVM default zones at connect time.
