Testing Multi-Database MongoDB Configuration in spring-boot-examples

This test suite validates the functionality of multiple MongoDB database configurations in a Spring Boot application. It demonstrates the simultaneous use of primary and secondary MongoDB repositories for user data management and persistence operations.

Test Coverage Overview

The test suite covers dual database operations with MongoDB in Spring Boot.

Key areas tested include:

User data persistence in primary database
User data persistence in secondary database
Retrieval operations from both databases
Concurrent database operations

Implementation Analysis

The testing approach utilizes Spring Boot’s test framework with JUnit integration. It implements @RunWith(SpringRunner.class) and @SpringBootTest annotations for proper Spring context loading.

The test demonstrates repository pattern implementation with:

Autowired dependency injection of repositories
Separate repository interfaces for primary and secondary databases
Sequential save and retrieve operations

Technical Details

Testing infrastructure includes:

JUnit 4 testing framework
Spring Boot Test context
MongoDB repositories configuration
User model implementation
Automated test execution with SpringRunner

Best Practices Demonstrated

The test implementation showcases several testing best practices:

Clear separation of concerns between primary and secondary repositories
Proper Spring Boot test configuration
Structured test method organization
Comprehensive database operation verification
Clear test execution logging
