Changes

Summary

This pull request implements auto-generated changes to address issue # 1. It primarily focuses on upgrading dependencies, refining database schema, and migrating to JUnit 5.

Key Changes:

• Dependency Upgrades:
  • Spring Boot upgraded from 2.0.4.RELEASE to 2.7.14.
  • Java version bumped from 1.8 to 17.
  • Lombok, Spring Security OAuth2, and Jackson Databind dependencies updated.
  • Spring Boot Starter Validation dependency added.
• Database Schema Refinement:
  • AUTO_INCREMENT replaced with IDENTITY for primary key generation in random_city, app_role, and app_user tables.
• JUnit 5 Migration:
  • JUnit 4 (org.junit.Test) replaced with JUnit 5 (org.junit.jupiter.api.Test).

Technical Details:

• The Spring Boot upgrade brings a significant version jump, potentially introducing breaking changes that necessitate code adjustments.
• Replacing AUTO_INCREMENT with IDENTITY aligns the database schema with more modern practices.
• Migrating to JUnit 5 offers a more robust and feature-rich testing environment.

Testing Considerations:

• Thorough regression testing is crucial due to the substantial dependency upgrades.
• Database-related tests should be reviewed to ensure compatibility with the schema changes.
• All unit tests need verification to function correctly within the JUnit 5 framework.
