Azure Pipelines: Local testing in CI

Test against a local Zuplo server before deploying anywhere.

Code
trigger:
  - main

pool:
  vmImage: ubuntu-latest

stages:
  - stage: LocalTest
    displayName: "Local Testing"
    jobs:
      - job: Test
        steps:
          - task: NodeTool@0
            inputs:
              versionSpec: "24.x"
            displayName: "Install Node.js"

          - script: npm install
            displayName: "Install dependencies"

          - script: |
              npx zuplo dev &
              DEV_PID=$!
              # Poll until the server answers — never a fixed sleep
              deadline=$((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
                  kill $DEV_PID
                  exit 1
                fi
                sleep 1
              done
              npx zuplo test --endpoint http://localhost:9000
              kill $DEV_PID
            displayName: "Start local server and run tests"

  - stage: Deploy
    displayName: "Deploy to Zuplo"
    dependsOn: LocalTest
    condition:
      and(succeeded(), eq(variables['Build.SourceBranch'], 'refs/heads/main'))
    jobs:
      - job: Deploy
        steps:
          - task: NodeTool@0
            inputs:
              versionSpec: "24.x"

          - script: npm install

          - script: npx zuplo deploy --api-key $(ZUPLO_API_KEY)
            displayName: "Deploy to Zuplo"

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.
