Validating Multi-Datasource MyBatis Configuration in spring-boot-examples

This test suite validates the Spring Boot application context loading and multiple datasource configuration using MyBatis annotations. It ensures proper initialization of the application context and verifies the basic setup of the multi-datasource environment.

Test Coverage Overview

The test suite focuses on validating the core application bootstrap process and context loading functionality.

Key areas covered include:

Application context initialization
Spring Boot configuration loading
Multiple datasource setup verification
Basic environment validation

Implementation Analysis

The testing approach utilizes Spring Boot’s test framework with JUnit integration. The @SpringBootTest annotation enables full application context loading, while @RunWith(SpringRunner.class) provides Spring testing support.

Key implementation patterns include:

Spring context testing
Annotation-based configuration
Integration test structure

Technical Details

Testing tools and configuration:

JUnit 4 test framework
Spring Boot Test module
SpringRunner test executor
MyBatis annotation configuration
Multiple datasource setup

Best Practices Demonstrated

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

Notable practices include:

Proper test class annotation setup
Clean separation of test concerns
Standard Spring Boot test configuration
Basic context validation approach
