What happens when your integration code is gets ready with IQBYT

Integration APIs are the arteries of the enterprise — and they're almost never tested properly. MuleSoft flows connect Salesforce to the ERP, process orders from the website, sync customer data across 5 systems. When one breaks, it's not a bug — it's a business outage. But who writes test cases for DataWeave transformations? Who verifies error handling when the ERP is down? Most organisations test integrations manually with Postman — if they test them at all.
