7.1 Update the CI workflow

  1. Open the workflow file ci-workflow.yml

    strategy:
      # Cancel all matrix jobs if one of them fails
      fail-fast: true
      matrix:
        # our matrix for testing across node versions and OSs
        node-version: [12, 14, 16]
        os: [macos-latest, windows-latest, ubuntu-latest]
  1. In the ci job, before the deploy-test job, copy the following YAML content to use the upload-artifact action:
      - shell: bash
        run: |
          echo 'Test upload artifact' > output.log
      - name: Upload output file
        uses: actions/upload-artifact@v2
        with:
          name: output-log-file
          path: output.log
  1. In the deploy-test job, after the checkout action, copyt the following YAML content to use the download-artifact action
      - name: Download a single artifact
