Testing Elasticsearch High-Level Client Operations in spring-boot-demo

This test suite demonstrates comprehensive testing of Elasticsearch operations in a Spring Boot application. It covers essential CRUD operations and index management using the Elasticsearch High Level REST Client, validating the PersonService implementation.

Test Coverage Overview

The test suite provides complete coverage of Elasticsearch operations including index management and CRUD functionality.

Index operations: creation and deletion
Document operations: insert, update, delete, and search
Data handling with Person entity objects
Integration with Spring Boot context

Implementation Analysis

The testing approach utilizes Spring Boot Test framework with JUnit4 integration. Tests are organized around the PersonService class, using @SpringBootTest for full application context loading and dependency injection. Each test method focuses on a specific Elasticsearch operation with clear separation of concerns.

Technical Details

Spring Test Context framework with @RunWith(SpringRunner.class)
JUnit4 test annotations
Elasticsearch High Level REST Client
Spring Boot Test configuration
PersonService autowiring for dependency injection

Best Practices Demonstrated

The test suite exemplifies several testing best practices for Elasticsearch integration.

Isolated test methods for each operation
Consistent use of test data structures
Clear test method naming conventions
Proper Spring Boot test configuration
Structured index and document management
