Write Integration Tests in Spring Boot like a PRO - Car Maintenance Tracker App

🚀 Welcome to Day 7 of building the Car Maintenance Tracker App!
In this stream, we’ll focus on:

02:04 - Explaining why integration tests are preferred over unit tests for comprehensive coverage
05:25 - Setting up test containers with PostgreSQL for the database testing environment
07:27 - Custom integration test annotation configuration and Spring Boot test setup
11:09 - Writing first integration test for car creation endpoint with database fixtures
23:15 - Discovering and addressing JWT authentication issues in test execution
30:03 - Fixing database migration problems and mapping configuration errors
34:55 - Implementing integration test for car update functionality with response validation
43:25 - Creating a delete test and addressing database cleanup challenges between tests
51:01 - Session wrap-up and preview of next session covering error cases and validation

This is a live coding session where I build the entire app from idea to production.
