Microsoft’s Commerce Platforms team developed Enterprise Test Platform, an AI-driven testing solution, to address bottlenecks in enterprise technology testing, including slow cycles, fragmented tools, and manual validation. The team, which owns the company’s core commerce and financial platform services, faced a critical SAP migration with a hard deadline. Testing across 40-plus SAP service lines had relied on third-party tools with finite capacity and manual test-case authoring, costing about $500,000 a year to maintain. With only 80 third-party tool licenses spread across more than 40 service lines, teams competed for capacity, and vendor remediation timelines stretched to 9 or 10 months. The Global Trade Services (GTS) system, which handles customs and invoice generation, had to migrate from SAP ERP Central Component to SAP Business Suite 4 HANA before a December 2025 deadline or shipments would stop. The team had 10 months. Instead of replacing the third-party platform overnight, they focused first on test-case authoring, using existing business process documentation to generate structured, executable test cases.
