Testing Multiple MyBatis Datasource Configuration in spring-boot-demo

This test suite validates the core configuration and context loading of a Spring Boot application with multiple MyBatis datasources. It ensures proper initialization and integration of multiple database connections within the Spring context.

Test Coverage Overview

The test coverage focuses on verifying the Spring application context initialization with multiple MyBatis datasources.

Validates successful context loading with multiple database configurations
Tests Spring Boot auto-configuration for MyBatis
Verifies datasource bean creation and initialization

Implementation Analysis

The testing approach utilizes Spring’s test framework with JUnit4 integration. The @RunWith(SpringRunner.class) annotation enables Spring test context support, while @SpringBootTest loads the complete application context for integration testing.

The implementation leverages Spring Boot’s auto-configuration capabilities to test multiple datasource configurations.

Technical Details

JUnit 4 testing framework
Spring Test Context framework
SpringRunner test executor
Spring Boot Test auto-configuration
MyBatis multiple datasource setup

Best Practices Demonstrated

The test class demonstrates several Spring testing best practices including proper test isolation and configuration.

Using appropriate Spring test annotations
Implementing context loading verification
Following Spring Boot testing conventions
Clean and focused test structure
