Unit Test Caching

This one generates unit test patterns for Spring Cache annotations without spinning up a full application context. You get test code that mocks CacheManager with ConcurrentMapCacheManager, verifies cache hits by checking repository call counts, and validates eviction and key generation logic. It covers the standard annotations (Cacheable, CacheEvict, CachePut) plus conditional caching scenarios with SpEL expressions. Honestly, this is most useful when you're adding caching to an existing service and want fast feedback on whether your annotations actually work before deploying. The examples show proper mock verification patterns, which is the tricky part most people get wrong when testing caching behavior.
