def add_expectation(expectation, mode=:instance)
  @instance_expectations << expectation unless mode == :class
  @class_expectations << expectation if mode == :class
end

#find(method_name, mode = :instance, *args) ⇒ Object

Finds an expectation in the collection. It matches by method_name first. Then it tries to figure out if you care about the arguments. You can say you don’t care by providing the symbol :any as first argument to this method. When you don’t care the first match is being returned When you specify arguments other than :any it will try to match the specified arguments in addition to the method name. It will then also return the first result it can find.
