Testing Spring Boot Context Loading Implementation in spring-boot-examples

This test suite validates the core Spring Boot application context loading functionality in a Spring Boot 2.0 environment. It ensures proper initialization of the Spring application context and demonstrates basic Spring Boot test configuration setup.

Test Coverage Overview

The test coverage focuses on verifying the successful loading of the Spring application context, which is a fundamental requirement for any Spring Boot application.

Validates basic context loading functionality
Tests Spring Boot 2.0 configuration initialization
Ensures proper test environment setup

Implementation Analysis

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

Uses SpringRunner test executor
Implements context loading verification
Demonstrates Spring Boot test configuration

Technical Details

The test suite leverages several key technical components:

JUnit 4 testing framework
Spring Boot Test 2.0 module
SpringRunner test executor
SpringBootTest annotation for context configuration

Best Practices Demonstrated

The test implementation showcases several Spring Boot testing best practices:

Proper test class annotation structure
Clean separation of test configuration
Use of appropriate Spring Boot test annotations
Basic context validation approach
