Pytest CI Color

When you run pytest in Github Actions then it'll run just fine but without any color.

Wouldn't it be nice to be able to see the same colors that you'd have in the terminal locally though? As luck would have it, you can configure this with a PYTEST_ADDOPTS environment variable. See the example below.

name: Build and Test

on:
  push:

jobs:
  unittest:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3

      - name: Set up Python
        uses: actions/setup-python@v4
        with:
          python-version: '3.11'
          cache-dependency-path: |
            requirements.txt
            dev-requirements.txt

      - name: Install dependencies
        run: |
          python -m pip install --upgrade pip
          python -m pip install -e .

      - name: Run pytest
        if: always()
        env:
          PYTEST_ADDOPTS: "--color=yes"
        run: |
          pytest tests

By configuring PYTEST_ADDOPTS: "--color=yes" in the env key you now get pretty colored output again.
