Microsoft is hereby announcing the deprecation of the Regression Suite Automation Tool (RSAT), effective May 15, 2027.
As of that date, Microsoft will no longer provide support, maintenance, bug fixes, or feature enhancements for RSAT. Customers may continue to use RSAT after the effective date; however, the product will remain available only on an unsupported basis.
This decision reflects Microsoft’s continued investment in modern testing approaches that support broader automation scenarios, greater extensibility, and long-term platform evolution. RSAT was developed primarily for Finance and Operations scenarios and does not address the broader end-to-end testing requirements that many organizations now have across connected applications and business processes.
- RSAT is optimized for Finance and Operations scenarios and offers limited support for broader cross-application testing requirements.
- Organizations increasingly require testing solutions that can scale across integrated business processes and support modern automation practices.
Customers should evaluate alternative testing solutions in accordance with their business and technical requirements, including offerings from the broader ecosystem of third-party testing vendors.
