GitLab CI/CD: Local testing in CI

Test against a local Zuplo server before deploying anywhere.

Code
image: node:24

stages:
  - test
  - deploy

local-test:
  stage: test
  script:
    - npm install
    - npx zuplo dev &
    # Poll until the server answers, with a hard deadline — never a fixed sleep
    - |
      deadline=$((SECONDS + 60))
      until curl --fail --silent --output /dev/null http://localhost:9000/health; do
        if (( SECONDS >= deadline )); then
          echo "Local server did not start within 60s" >&2
          exit 1
        fi
        sleep 1
      done
    - npx zuplo test --endpoint http://localhost:9000
    - kill %1

deploy:
  stage: deploy
  needs:
    - local-test
  script:
    - npm install
    - npx zuplo deploy --api-key "$ZUPLO_API_KEY"
  only:
    - main

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

The readiness poll replaces a fixed sleep. A sleep is a guess about startup time that is wrong in both directions, and it is the most common reason a gateway test suite "needs" a retry. The example polls /health — add an unauthenticated health route if your gateway does not have one. See health checks.
