Why use unit tests for caching instead of integration tests?

Unit tests are significantly faster and allow you to isolate and debug the caching logic, annotations, and keys independently from environment or network configuration issues.

Do I need a running Redis instance for these tests?

No, this skill focuses on using ConcurrentMapCacheManager, a lightweight in-memory provider that allows for fast testing without external infrastructure.

How do I verify a cache hit occurred?

You use Mockito's verify(times(1)) to check that the underlying repository or service method was called exactly once, even when the service method is invoked multiple times.

Can I test complex SpEL keys with this skill?

Yes, the skill includes patterns for validating that dynamic keys generated via SpEL expressions in the @Cacheable annotation produce the correct cache entries.

安全与测试

Provides standardized patterns for unit testing Spring Boot caching behavior to verify cache hits, misses, and invalidation logic.

This skill provides specialized guidance for testing Spring caching annotations (@Cacheable, @CacheEvict, @CachePut) using lightweight, in-memory cache managers. It enables developers to validate cache hit/miss scenarios, SpEL-based key generation, and complex invalidation logic without the overhead of a full Spring application context or external infrastructure like Redis. By using Mockito to verify invocation counts, this skill ensures that your caching layer performs correctly and efficiently while maintaining a fast, reliable test suite.
