 expect($cacheFactory.get('cacheId')).toBe(cache);
 expect($cacheFactory.get('noSuchCacheId')).not.toBeDefined();

 cache.put("key", "value");
 cache.put("another key", "another value");

 // We've specified no options on creation
 expect(cache.info()).toEqual({id: 'cacheId', size: 2});

  • {{*}} get({string} key) — Returns cached value for key or undefined for cache miss.
  • {void} remove({string} key) — Removes a key-value pair from the cache.
  • {void} removeAll() — Removes all cached values.
  • {void} destroy() — Removes references to this cache from $cacheFactory.
