Overview

CircleCI Build Status CircleCI Orb Version Apache 2.0 License CircleCI Community

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. For more information, see API and Application Keys.
  2. Ensure the image running the orb is a Linux x64 base image with cURL installed.
  3. Customize your workflow by creating a run-tests.yml file and following the naming conventions to specify inputs for your workflow.

Your workflow can be simple or complex.

Simple usage

Example orb usage using public IDs

version: 2.1

orbs:
  synthetics-ci: datadog/synthetics-ci-orb@2.2.0

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

This orb overrides the path to the pattern for test files.

version: 2.1

orbs:
  synthetics-ci: datadog/synthetics-ci-orb@2.2.0

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

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

For another example pipeline that triggers Synthetic tests, see the simple-example.yml file.

Complex usage

Example orb usage using the test_search_query

version: 2.1

orbs:
  synthetics-ci: datadog/synthetics-ci-orb@2.2.0

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 Continuous Testing Tunnel

version: 2.1

orbs:
  synthetics-ci: datadog/synthetics-ci-orb@2.2.0

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

For additional options such as customizing the pollingTimeout for your CircleCI pipelines, see CI/CD Integrations Configuration. For another example pipeline that starts a local server and triggers Synthetic tests using the Continuous Testing Tunnel, see the advanced-example.yml file.

Inputs

To customize your workflow, you can set the following parameters in a run-tests.yml file:

NameTypeDefaultDescription
api_keyenv var nameDATADOG_API_KEYThe name of the environment variable containing the API key.
api_keyenv var nameDATADOG_APP_KEYThe name of the environment variable containing the app key.
config_pathstringdatadog-ci.jsonThe global JSON configuration used when launching tests.
fail_on_critical_errorsbooleanfalseFail if tests were not triggered or results could not be fetched.
fail_on_timeoutbooleantrueForce the CI to fail (or pass) if one of the results exceeds its test timeout.
filesstring{,!(node_modules)/**/}*.synthetics.jsonGlob pattern to detect Synthetic tests config files.
