What is Microsoft Test Base

Microsoft recently announced that ‘Test Base for Microsoft 365’ has moved from the private preview stage to public preview.

They’ve also taken steps to make this new service more discoverable on the Azure portal.

What is Microsoft Test Base?

Test Base for Microsoft 365 is a new Azure service for app developers and IT professionals that uses data-driven testing of applications and enables you to take advantage of testing from anywhere. Test Base helps you to keep tabs on your application’s performance and compatibility as underlying platform changes continually occur in Windows. You don’t need to worry about building a test lab or designing an environment that’s safe and secure to perform said testing. Microsoft takes care of that for you. The coolest feature is being able to test your apps automatically against Windows and pre-release Windows updates on secure virtual machines. Windows 11 testing will also soon be available as a platform for your applications.
