Validating Spring Boot Context Loading with Docker Compose in spring-boot-examples

This test suite validates the Spring Boot application context loading in a Docker Compose environment. It ensures proper initialization of the Spring application context and demonstrates basic container configuration for development and testing purposes.

Test Coverage Overview

The test coverage focuses on verifying successful Spring Boot context initialization within a containerized environment. The suite ensures:

Basic application context loading
Docker Compose configuration compatibility
Spring Boot test environment setup

Implementation Analysis

The testing approach utilizes Spring Boot’s testing framework with JUnit integration. It employs @SpringBootTest annotation for full application context loading and @RunWith(SpringRunner.class) for Spring test execution.

The implementation demonstrates the Spring testing patterns with Docker Compose integration.

Technical Details

Key technical components include:

JUnit 4 testing framework
Spring Boot Test context
SpringRunner test executor
Docker Compose configuration
System output verification

Best Practices Demonstrated

The test suite exemplifies several testing best practices:

Clean separation of test configuration
Proper use of Spring Boot test annotations
Integration with containerized environments
Minimal test scope for context loading
