## What is TDD?
An attempt at a better way, by automating tests.
## Normal Software Development
##Why We TDD
- Immediate feedback
- Confidence to refactor
- Executeable documentation
- Design insight
## Red Green Refactor
## Our Kata
## What is a Tamagotchi
A Tamagotchi is a small, handheld digital pet that you can feed, play with, put to bed and clean up after. Look after it well by feeding it the right kinds of foods, showering it with attention and cleaning up after it when required, and your Tamagotchi will grow up to be a smart, well-respected member of society. Ignore its needs and its mood will sour until it eventually dies.
## Our Stories
- Tamagotchi has basic stats
- Feeding Tamagotchi
- Making Tamagothci poo
- Tamagotchi's needs change over time
- Tamagotchi can be Hangry
- Tamagotchi can be Dead

AND it has a default Fullness stat 50
## Feeding Tamagotchi
As a Tamagotchi owner

THEN its hunger is increased by 10
## Tamagotchi Can Be 😿
As a Tamagotchi owner
I want to know when my Tamagotchi is hangry

## Tamagotchi Can Be 💀

# DONE
## Dedicated Mocking Frameworks
- SinonJS
- TestDoubleJS
What other features could we add that might benefit from mocking?
#Thank you!
