code: public static synchronized <T> IExpectationSetters<T> expectPrivate(Object instance, String methodName,
                                                                          Class<?> where, Object... arguments) throws Exception {
          return expectPrivate(instance, methodName, where, null, arguments);
      }
docs: Used to specify expectations on methods using the method name at a
  specific place in the class hierarchy (specified by the
  {@code where} parameter). Works on for example private or package
  private methods.
