# Cafe Fika Kata

## Setup

Locally run `pipenv install`. If you don't have pip installed 

you'll need to run `pip install pipenv` first.

Once this is setup run `./test.sh`

## Kata Requirements

### Requirement One - Pricing

We want to be able to find out the price of some simple items

Coffee - 5kr

Fancy Coffee - 8kr

Kanelbulle - 10kr

### Requirement Two - Basket shopping

We get a list of items from the customer.

What's the total?

### Requirement Three - Different cafes have different prices

Extend the above so we can have multiple shops with

different prices

### Requirement Four - Stock levels

A cafe has limited stock. When it's sold out orders can't be

placed for that time.

### Requirement Five - Closing down

When a cafe has no stock of any kind it closes down.

### Requirement Six - Let's take fika international

All the previous requirements dealt in Krona. 

Now we want to launch in new countries. Each cafe

should only work in a single currency. 

### Requirement Seven - Special offers

There's now a special offer on the bullar.

If a customer buys 3 they only pay 25kr.

## Considerations

Part of the focus of this Kata is using the type system 

with mypy. 

When defining your functions and classes start to think 

about what types they will receive and output. Dataclasses 

added in 3.7 can also help with this.
