unit-test-caching

Unit test Spring Cache behavior by configuring an in-memory CacheManager in your test class, then verify cache hits, misses, and eviction by mocking dependencies and asserting method call counts. This validates caching logic without a full Spring context or external cache systems.

Yes. Use mock-based unit tests with an in-memory CacheManager to validate @Cacheable, @CachePut, and @CacheEvict behavior in isolation. This approach runs fast, requires no external cache infrastructure, and keeps tests focused on cache configuration and key generation logic.

Write unit tests that mock your repository, apply Spring cache annotations to the method under test, and assert the repository is called once for a cached result but multiple times without caching. This confirms cache hits prevent redundant calls while maintaining correctness.

Test conditional caching by configuring @Cacheable with condition attributes and verifying cache state changes. Test invalidation by using @CacheEvict and @CachePut to validate updates and removals, all within an in-memory test cache without external dependencies.

No. You can test Spring cache annotations with minimal setup: add spring-boot-starter-cache, configure a CacheManager bean in your test, and write unit tests. Spring's caching abstraction works independently of the full Boot context, enabling fast, focused cache validation.
