GildedRose-Refactoring-Kata/README.md

This is my implementation of the Gilded Rose Kata.

Tidy first, then change behavior

/main

In the main branch is only refactored from the original, with the new requirement yet to implemented. I used the lift up conditional refactoring, inspired by Emily Bache and Llewellyn Falco.

See their videos here:

/feature/implement-new-requirement

In this branch, I have implemented the new requirement.

/archive/original-code

This branch contains the original code, before the refactoring.

Getting setup

Firstly, setup a python 3.12 environment using venv

Then, install the requirements:

pip install -r requirements.txt

Running the tests

This project uses characterisation testing to ensure the behavior of the code remains the same during refactoring. Specifically, it uses pytest-approvals

coverage run --branch -m pytest --approvaltests-add-reporter=diffuse -s ;
coverage html ;
coverage report --fail-under=100

This will run the tests, and will also:

• automatically bring up diffuse to view differences side by side, if there are any behavior changes.
  • feel free to install and use a diff reporter of your choice. See pytest docs for more info on configuring reporters: selecting a reporter
• warn you if your coverage falls below 100% (either you need more tests, or there is dead code)
• generate a coverage report (You can view this in the htmlcov directory by opening index.html in a browser)
