Validating Multi-Datasource Context Loading in spring-boot-examples

This test suite validates the Spring Boot application context loading and basic configuration setup for a multi-datasource MyBatis implementation. It ensures the core application components initialize correctly and the Spring context loads properly with multiple database configurations.

Test Coverage Overview

The test coverage focuses on verifying successful Spring context initialization with multiple datasources configured.

Key areas tested include:

Spring Boot application context loading
Multiple datasource configuration validation
Basic MyBatis integration verification
Spring Runner execution environment

Implementation Analysis

The testing approach utilizes Spring Boot’s test framework with JUnit 4 integration. The implementation leverages @SpringBootTest for full application context testing and @RunWith(SpringRunner.class) to enable Spring TestContext Framework support.

Notable patterns include:

Context initialization verification
Spring Runner integration
Test environment configuration

Technical Details

Testing tools and configuration:

JUnit 4 testing framework
Spring Boot Test context
SpringRunner test runner
System.out verification
Spring Boot test annotations
Context configuration validation

Best Practices Demonstrated

The test suite demonstrates several testing best practices for Spring Boot applications.

Notable practices include:

Proper test class annotation usage
Clean separation of test responsibilities
Effective use of Spring Boot test infrastructure
Clear test method naming conventions
Appropriate scope for context loading tests
