Microcks GitHub Actions

What is it?

Microcks provides 2 GitHub Actions for interacting with a Microcks instance from your GitHub workflows:

• The Microcks Import GitHub Action is a GitHub Action you may use in your Workflow to import a bunch of API artifacts in a Microcks installs. If test succeeds (ie. API endpoint is compliant with API contract in Microcks) the workflow is pursuing, if not it fails,

• The Microcks Test GitHub Action is a GitHub Action you may use in your Workflow to launch a Microcks test on a deployed API endpoint. If test succeeds (ie. API endpoint is compliant with API contract in Microcks) the workflow is pursuing, if not it fails.

Those 2 actions are basically a wrapper around the Microcks CLI and provides the same configuration capabilities. Especially, they’re sharing the same mandatory configuration parameters that are

• microcksURL for the Microcks API endpoint,
• keycloakClientId for the Keycloak Realm Service Account ClientId,
• keycloakClientSecret for the Keycloak Realm Service Account ClientSecret.

How to use them?

Obviously we can find this action with GitHub Actions Marketplace 😉

You may add one of the Action to your Workflow directly from the GitHub UI.

Import GitHub action

The import action, based on the CLI command, has just one argument that specifies a comma separated list of file paths:

• <specificationFile1[:primary],specificationFile2[:primary]> : The file paths with an optional flag telling if it should be imported as primary or not. See Multi-artifacts support doc. Default is true so it is considered as primary.

Step 1 - Configure the GH action

Here’s an example below:

name: my-workflow
on: [push]
jobs:
  my-job:
    runs-on: ubuntu-latest
    environment: Development
    steps:
      - uses: microcks/import-github-action@v1
        with:
          specificationFiles: 'samples/weather-forecast-openapi.yml:true,samples/weather-forecast-postman.json:false'
          microcksURL: 'https://microcks.apps.acme.com/api/'
          keycloakClientId:  ${{ secrets.MICROCKS_SERVICE_ACCOUNT }}
          keycloakClientSecret:  ${{ secrets.MICROCKS_SERVICE_ACCOUNT_CREDENTIALS }}

Step 2 - Configure the Secrets

As you probably saw just above, we do think it’s a best practice to use GitHub Secrets (general or tied to Environment like in the example) to hold the Keycloak credentials (client Id and Secret). See below the Secrets configuration we’ve used for the example:

Test GitHub action

The test action, based on the CLI command, needs 3 arguments:

• <apiName:apiVersion> : Service to test reference. Exemple: 'Beer Catalog API:0.9'
• <testEndpoint> : URL where is deployed implementation to test
• <runner> : Test strategy (one of: HTTP, SOAP, SOAP_UI, POSTMAN, OPEN_API_SCHEMA, ASYNC_API_SCHEMA)

And some optional ones:

• --waitFor for the time to wait for test to finish (int + one of: milli, sec, min). Default is 5sec,
• --secretName='<Secret Name>' is an optional flag specifying the name of a Secret to use for connecting endpoint,
• --operationsHeaders=<JSON> allows to override some operations headers for the tests to launch.

Step 1 - Configure the GH action

Here’s an example below:

name: my-workflow
on: [push]
jobs:
  my-job:
    runs-on: ubuntu-latest
    environment: Development
    steps:
      - uses: microcks/test-github-action@v1
        with:
          apiNameAndVersion: 'API Pastry - 2.0:2.0.0'
          testEndpoint: 'http://my-api-pastry.apps.cluster.example.com'
          runner: OPEN_API_SCHEMA
          microcksURL: 'https://microcks.apps.acme.com/api/'
          keycloakClientId:  ${{ secrets.MICROCKS_SERVICE_ACCOUNT }}
          keycloakClientSecret:  ${{ secrets.MICROCKS_SERVICE_ACCOUNT_CREDENTIALS }}
          waitFor: '10sec'

Step 2 - Configure the Secrets
