How can I implement code coverage in Python with CI?

You can use tools like pytest with the pytest-cov plugin to measure code coverage in your Python projects.

What CI tools can I integrate with pytest for coverage?

You can integrate with CI tools like GitHub Actions, Travis CI, or CircleCI to automate your tests and coverage reports.

Can you show me a sample configuration for GitHub Actions?

Sure! Here's a basic example of a GitHub Actions workflow:

name: Python package

on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
    - name: Set up Python
      uses: actions/setup-python@v2
      with:
        python-version: '3.8'
    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install pytest pytest-cov
    - name: Run tests with coverage
      run: |
        pytest --cov=your_package tests/

How do I view the coverage report after running the tests?

You can view the coverage report in the terminal after the tests run, or you can generate an HTML report by adding --cov-report html to your pytest command.
