Do I need Redis to use this caching test skill?

No, these tests utilize the Spring ConcurrentMapCacheManager for fast, in-memory testing that requires no external infrastructure or containers.

Can I test caching without a running database?

Yes, this skill uses Mockito to mock repositories, allowing you to verify caching logic by checking the number of times the underlying repository method is actually invoked.

Does this support testing complex SpEL keys?

Yes, it includes patterns for verifying that complex SpEL expressions in @Cacheable(key = '...') generate the expected cache keys and behavior.

How do I verify if a cache hit actually occurred?

The skill demonstrates how to use Mockito's verify method to ensure the repository is called only once (times(1)) even when the service method is called multiple times.

Security & Testing

Validates Spring Cache annotations and behavior using JUnit 5 and Mockito to ensure efficient data retrieval and invalidation logic.

This skill provides standardized patterns and implementations for unit testing Spring Framework's caching abstractions. It enables developers to verify the logic of @Cacheable, @CacheEvict, and @CachePut annotations by mocking repositories and observing call frequencies. By utilizing an in-memory CacheManager, this skill facilitates rapid testing of hit/miss scenarios, cache key generation, and complex conditional caching logic without requiring external systems like Redis or an expensive full application context load.

Key Features

01Mocking repository dependencies for isolated testing

02Validation of @Cacheable hit and miss logic

03Testing @CacheEvict invalidation strategies

04Conditional caching verification using unless/condition

05Testing SpEL-based cache key generation
