{
var cacheManager = new CacheManager();
string key = "key" + DateTime.Now.Ticks;
object value = "value" + DateTime.Now.Ticks;
bool valueCalled = false;
Func<string, object> valueFactory = k => { valueCalled = true; return value; };

Assert.IsNotNull(result);
Assert.IsTrue(valueCalled);
Assert.AreEqual(value, result);
// value factory 2 should not be called
