Testing Spring Boot Context Loading with MyBatis Multi-Datasource in spring-boot-examples

This test suite validates the Spring Boot application context loading and basic configuration setup using JUnit and Spring Test framework. It ensures the application bootstraps correctly with multiple datasource configurations using MyBatis annotations.

Test Coverage Overview

The test coverage focuses on verifying the Spring application context initialization with multiple datasource configurations.

Tests successful application context loading
Validates Spring Boot autoconfiguration
Verifies multiple datasource setup with MyBatis annotations
Ensures basic application bootstrapping

Implementation Analysis

The implementation utilizes Spring Boot’s test framework with JUnit integration for context loading verification. The test class leverages @SpringBootTest annotation for full application context loading and @RunWith(SpringRunner.class) for Spring test execution.

Key patterns include:

Spring Runner integration for test execution
Context loading validation
Test class configuration with Spring annotations

Technical Details

Testing Tools & Configuration:

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

Best Practices Demonstrated

The test implementation follows Spring Boot testing best practices with proper separation of concerns and clear test structure.

Proper test class annotation usage
Clean test method organization
Framework-recommended context loading approach
Effective use of Spring Boot test annotations
