Setup Developer Environment

These instructions will take you through the minimal steps required to get a dev environment setup, so you can run the tests locally.

Clone the repository

First clone the repository locally using Git. There is a link on the GitHub interface to allow you to do this. SSH is recommended if you have setup a key. Enter the directory that it is cloned into to continue.

Install dependencies

You can choose to either develop on the host machine using a venv (which requires python 3.8 or later) or to run in a container under VSCode

Local virtualenv

python3 -m venv venv
source venv/bin/activate
pip install -c requirements/constraints.txt -e .[dev]

VSCode devcontainer

code .
# Click on 'Reopen in Container' when prompted
# Open a new terminal

Build and test

Now you have a development environment you can run the tests in a terminal:

tox -p

This will run in parallel the following checks:

• Build the docs using sphinx

• Run the tests using pytest

• Run static analysis using pyright or mypy

• Run linting using pre-commit
