wdio-cloud-container-service/test/http.mock.js

This WebdriverIO service triggers a cloud run service, or other container-based cloud container service on any platform. Examples include Google Cloud Run and Heroku. The service performs the trigger, and a health check, by requesting the /status endpoint
