How do I set up Codecov for my project?

To set up Codecov, first, you need to create an account on their website and link it to your repository.

What if I'm using GitHub Actions for CI?

If you're using GitHub Actions, you can add a Codecov step in your workflow YAML file to upload coverage reports.

Can you show me an example of the YAML configuration?

Sure! Here's a basic example:

name: CI
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set up Node.js
        uses: actions/setup-node@v2
        with:
          node-version: '14'
      - run: npm install
      - run: npm test -- --coverage
      - name: Upload coverage to Codecov
        uses: codecov/codecov-action@v1
        with:
          file: ./coverage/lcov.info

Do I need to add any specific tokens for authentication?

Yes, you'll need to add your Codecov token as a secret in your GitHub repository settings to authenticate uploads.
