Title: Fixed callCount 

Because we need a convenient function for asserting number of call one made. There is only a properties like ?`calledOnce`, `calledTwice`, `calledThrice`. Though these solution doesn't scale beyond 3 calls. So it would be good with a method like `callCount()` that can scale infinitely.
