# CircleCI: Local Testing in CI

Test against a local Zuplo server before deploying anywhere.

```yaml title=".circleci/config.yml"
version: 2.1

jobs:
  local-test:
    docker:
      - image: cimg/node:20.0
    steps:
      - checkout
      - run: npm install
      - run:
          name: Start local server and run tests
          command: |
            npx zuplo dev &
            sleep 10
            npx zuplo test --endpoint http://localhost:9000
            kill %1

  deploy:
    docker:
      - image: cimg/node:20.0
    steps:
      - checkout
      - run: npm install
      - run: npx zuplo deploy --api-key "$ZUPLO_API_KEY"

workflows:
  test-and-deploy:
    jobs:
      - local-test
      - deploy:
          requires:
            - local-test
          filters:
            branches:
              only: main
```

Local tests run first. Only if they pass does deployment proceed.

## Next Steps

- Add [multi-stage deployment](./multi-stage-deployment.mdx) with staging
