Datadog Synthetics CircleCI Orb

Overview

Run Synthetic tests in your CircleCI pipelines using the Datadog CircleCI orb.

The CircleCI command orb installs datadog-ci and uses the datadog-ci synthetics run-tests command to execute Datadog Synthetic tests.

Setup

To get started:

1. Add your Datadog API and application keys as environment variables to your CircleCI project. See inputs for naming conventions. For more information, see API and Application Keys.
2. Ensure the image running the orb is a Linux x64 base image with cURL installed.

Your workflow can be simple or complex.

Simple usage

Example orb usage using public IDs

version: 2.1

orbs:
  synthetics-ci: datadog/[email protected]

jobs:
  e2e-tests:
    docker:
      - image: cimg/base:stable
    steps:
      - synthetics-ci/run-tests:
          public_ids: 'abc-d3f-ghi, jkl-mn0-pqr'

workflows:
  run-tests:
    jobs:
      - e2e-tests

Example orb usage using a global configuration override

version: 2.1

orbs:
  synthetics-ci: datadog/[email protected]

jobs:
  e2e-tests:
    docker:
      - image: cimg/base:stable
    steps:
      - synthetics-ci/run-tests:
          files: e2e-tests/*.synthetics.json

workflows:
  run-tests:
    jobs:
      - e2e-tests

Complex usage

Example orb usage using the test_search_query

version: 2.1

orbs:
  synthetics-ci: datadog/[email protected]

jobs:
  e2e-tests:
    docker:
      - image: cimg/base:stable
    steps:
      - synthetics-ci/run-tests:
          test_search_query: 'tag:e2e-tests'

workflows:
  run-tests:
    jobs:
      - e2e-tests

Example orb usage using the Synthetic Testing Tunnel

version: 2.1

orbs:
  synthetics-ci: datadog/[email protected]

jobs:
  e2e-tests:
    docker:
      - image: your-image
    steps:
      - checkout
      - run:
          name: Running server in background
          command: npm start
          background: true
      - synthetics-ci/run-tests:
          config_path: tests/tunnel-config.json
          files: tests/*.synthetics.json
          test_search_query: 'tag:e2e-tests'
          tunnel: true

workflows:
  test-server:
    jobs:
      - build-image
      - integration-tests:
          requires:
            - build-image
