0.22.9

Changes

• Migrate to JUnit 5: Replace JUnit 4 with JUnit Jupiter 5.11.0
• Update all test annotations (@Before → @BeforeEach)
• Convert @Test(expected=...) to assertThrows()
• Add useJUnitPlatform() to Gradle test task

Why This Matters

Dependent projects can now extend PostgresSchemaTest and DatabaseTest using pure JUnit 5 without requiring junit-vintage-engine.
