         // set max cache size
         const f = cacheIt((value: number) => (++idx) + value, {
           providerOptions: {
             params: {
               max_entries: 2
             }
           }
         });
         expect(f.__cache_storage["_maxSize"]).toBe(2);

         expect(f(0)).toBe(1);
         expect(f(0)).toBe(1);
