Barista API

In this projects should you create an Fluent API for a barista to create espresso based drinks using code. To get into the Barista domain have a look at The Ultimate Beginner's Guide to Espresso they also have a A Beginner's Guide to Espresso video serie (5 parts).

The API should be made for a barista-programmer, and he/she should be able to produce the following six cofee types using the API:

The final method of the API should return a beverage-object of the correct type, depending on the methods which have been executed.

An example of how the API could look (this is pseudo-code!!):

IBeverage espresso = new FluentEspresso()
                            .AddWater(20)
                            .AddBeans(new Bean(){ 
                                AmountInG = 5,
                                Sort = CoffeSorts.Robusta})
    						.Validate(e => e.Temerature > 90)
                        .ToBeverage();
// espresso is type of Espresso

IBeverage latte = new FluentEspresso()
                            .AddBeans(new Bean(){ 
                                AmountInG = 5,
                                Sort = CoffeSorts.Robusta})
                            .GrindBeans()
                            .AddWater(20)
                            .AddMilk()
       						.Validate(e => e.Temerature < 80)
                        .ToBeverage();
// latte is type of Latte

See the IBeverage in code project : BaristaApi/Beverage.cs

The solution

The solution should cover the following:

• Encapsulation, Inheritance, Polymorphism, Abstraction
• A fluent api, which uses some lambda expressions
• Unit tests, is a must that the solution contains some unit tests

Extra

• The usage of attributes
