})();This script uses the Postman API to create a monitor with specified regions. It sends a POST request with the monitor details including the collection UID and the regions array.
After creation, it polls the monitor runs endpoint every 15 seconds up to 5 minutes to wait for a completed run.
Once a run is completed, it verifies that each selected region has a run status of 'passed'. If any region is missing or failed, it throws an error.
This approach uses explicit waits and checks API responses carefully, following best practices for asynchronous operations and API testing.
