PR review: “Bugs investigation”

What looks good

• Fixes the root cause: @SpringBootTest was failing because Flyway tried to connect to local Postgres; switching tests to in-memory H2 removes that environment dependency.
• Scoped to tests: using application-test.properties + @ActiveProfiles("test") keeps production/dev config unchanged.
• CI-friendly: ./gradlew test runs green without provisioning Postgres.

Potential issues / improvements

• Flyway disabled in tests: this means tests won’t catch migration errors. That’s fine for contextLoads(), but consider adding a separate integration test profile later (e.g., Testcontainers Postgres) to validate migrations.
• DDL strategy difference: spring.jpa.hibernate.ddl-auto=create-drop in tests won’t reflect your Flyway schema exactly. Again OK for now, but be aware it can hide schema mismatches.
• H2 PostgreSQL mode is helpful but not perfect: some Postgres-specific SQL/features can still behave differently under H2.

Nits (optional)

• If you add more tests later, you may want a global test configuration (e.g., @ActiveProfiles("test") via a base test class) so you don’t repeat the annotation.

Verdict

LGTM for the stated goal: making backend tests run without a PostgreSQL instance.
