Now it’s time to create a MockRepository that inherits from the interface it’s method.

Inside the constructor we create some mockdata with orders.

        private List<Order> orders;
        public MockOrderRepository()
        {
            orders = new List<Order>()
            {
                new Order() { CustomerName = "Sherlock", CoffeeSelected = Coffee.Cappuccino},
                new Order() { CustomerName = "Pluto", CoffeeSelected = Coffee.Espresso},
                new Order() { CustomerName = "Garfield", CoffeeSelected = Coffee.Frappuccino}
            };
        }

Now in the method GetAllOrders return the list of orders.

        public IEnumerable<Order> GetAllOrders()
        {
            return orders;
        }

Next let’s create a controller that implements the Order interface repository.
