Unit Testing Spring Caching

Overview

This skill provides patterns for unit testing Spring caching annotations (@Cacheable, @CacheEvict, @CachePut) without full Spring context. It covers cache hits/misses, invalidation, key generation, and conditional caching using in-memory ConcurrentMapCacheManager.

When to Use

• Writing unit tests for @Cacheable method behavior
• Verifying @CacheEvict cache invalidation works correctly
• Testing @CachePut cache updates
• Validating cache key generation from SpEL expressions
• Testing conditional caching with unless/condition parameters
• Mocking cache managers in fast unit tests without Redis
