[zzak]

Here's an example:

    steps:
      - checkout
      - run: npm install tap-junit
      - run: npm install
      - run: npm run test:ci | ./node_modules/tap-junit/bin/tap-junit --output test_results --name junit
      - store_artifacts:
          path: test_results
          prefix: test_results
      - store_test_results:
          path: test_results
