Testing JPA Specification Pagination and Filtering in spring-boot-examples

This test suite validates Spring Boot JPA Specification functionality with pagination and dynamic querying capabilities. It focuses on testing custom user detail search operations with complex filtering conditions and result sorting.

Test Coverage Overview

The test suite covers pagination and filtering functionality for UserDetail entities using Spring Data JPA Specifications.

Key areas tested include:

Dynamic query building with multiple conditions
Age range filtering
Custom text search on introduction field
Pagination implementation
Result sorting capabilities

Implementation Analysis

The testing approach utilizes Spring Boot’s test framework with JUnit4 integration. It implements @RunWith(SpringRunner.class) for Spring context loading and leverages @SpringBootTest for full application context testing.

Notable patterns include:

Resource injection for service layer testing
PageRequest implementation for pagination
Sort specification configuration
Parameter object usage for search criteria

Technical Details

Testing tools and configuration:

JUnit 4 testing framework
Spring Boot Test context
Spring Data JPA Specification
PageRequest for pagination handling
Sort class for result ordering
UserDetailParam for search criteria encapsulation

Best Practices Demonstrated

The test implementation showcases several testing best practices in Spring Boot applications.

Notable practices include:

Proper separation of concerns with service layer testing
Structured parameter object usage
Clear test method naming conventions
Efficient pagination implementation
Proper resource cleanup through Spring context management
