Testing Dynamic Datasource Configuration in spring-boot-demo

This test suite validates the core functionality of dynamic datasource configuration in a Spring Boot application. It focuses on ensuring proper context loading and datasource initialization within the Spring container environment.

Test Coverage Overview

The test coverage focuses on Spring context initialization and dynamic datasource configuration validation.

Verifies successful application context loading
Tests Spring Boot autoconfiguration for multiple datasources
Validates dynamic datasource switching capabilities
Ensures proper bean initialization in the Spring container

Implementation Analysis

The testing approach utilizes Spring’s test framework with JUnit integration for comprehensive application context testing.

The implementation leverages @SpringBootTest for full application context loading and @RunWith(SpringRunner.class) to enable Spring testing infrastructure. This allows for thorough validation of datasource configuration and runtime behavior.

Technical Details

JUnit 4 testing framework
Spring Test context framework
SpringRunner test executor
Spring Boot test annotations
Dynamic datasource configuration

Best Practices Demonstrated

The test suite demonstrates several Spring testing best practices including proper test isolation and context management.

Clean separation of test configuration
Proper use of Spring Boot test annotations
Efficient context loading strategy
Clear test class organization
