For many enterprises operating in the Microsoft Dynamics 365 (D365) ecosystem, Microsoft's Regression Suite Automation Tool (RSAT) appears to be the default path for automated testing. It's free, built by Microsoft, and tightly integrated with Task Recorder and DevOps. But is that enough?
At first glance, RSAT offers an appealing entry point into test automation. However, when D365 environments become more complex, business process coverage deepens, and the need for regression testing scales across multiple updates, RSAT's limitations start to show.
This is the story of a UK-based fashion retailer with more than 40 stores and a multi-channel D365 implementation. The retailer believed RSAT would meet its testing needs, until it didn't.
The retailer began its D365 journey with RSAT. Its goal was simple: avoid manual regression testing during Microsoft's continuous updates. The team used Task Recorder to generate test cases and fed them into RSAT for execution.

RSAT Advantage |
Description |
|
Native D365 Integration |
RSAT syncs easily with D365 via Task Recorder. |
|
Azure DevOps Connectivity |
Out-of-the-box integration with Azure DevOps test plans. |
|
Zero-cost Licensing |
As a Microsoft tool, RSAT comes at no additional licensing cost. |
But challenges began to surface:
|
RSAT Limitation |
Business Impact |
|
Non-functional coverage |
No ability to test performance or cross-browser. |
|
Code dependency |
Required PowerShell scripting and Excel manipulation. |
|
Lack of scalability |
Increased maintenance overhead with expanding test cases. |
|
No cross-module orchestration |
Tests could not span across Finance, SCM, and CRM processes. |
There's also a deadline attached to this decision. Microsoft has confirmed RSAT's official end of support: May 15, 2027. After that date, there's no maintenance, no bug fixes, and no support. Teams with large regression suites should start planning the move now, not when the deadline is weeks away.

D365 ships two major release waves a year, plus monthly minor updates, and each one carries the potential to break something in production. The retailer faced what many D365 enterprises encounter: upgrade fatigue, continuous cycles of manual validations, broken test scripts, and failed deployments.
This created:
The retailer's IT team began evaluating purpose-built automation platforms that could scale, were no-code, and offered full-stack regression capabilities.
Enterprises like this one understood the need for better test automation and transitioned to Avo Assure, Avo's no-code platform for Dynamics 365 business process assurance, built on Business-Aware, Accountable AI.

Avo Assure's pre-built D365 libraries help teams build test cases without writing code. Parallel execution meant the retailer could run its full regression suite in a fraction of the time it previously took a multi-person testing team working manually.
Transitioning to Avo Assure didn't just reduce test effort. It transformed the entire delivery model:
RSAT gets you started, but it wasn't built to carry a full-scale D365 rollout.
If your organization:
...then RSAT won't cut it.
Avo Assure proves what no-code test automation can actually do at enterprise scale. This retailer's experience is a testament to what can be achieved when you choose a platform that's built for the complexity of enterprise D365 ecosystems.
Every Dynamics 365 release is a business risk. Avo turns it into a competitive advantage.Book your D365 demo to see how Business-Aware, Accountable AI can assure your next release, or download the D365 Regression Checklist to start planning your move off RSAT.
