Unit Test Caching

giuseppe-trisciuoglio/developer-kit

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.

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
