In this article, you’ll find about everything you need to know about testing your Microsoft platforms and systems.
The Microsoft ecosystem: Testing is the key to a successful setup
Microsoft offers a comprehensive business technology stack, including ERP (Enterprise resource planning), CRM (customer relationship management), cloud services, collaboration tools, and AI-driven applications including Microsoft Copilot.
Each of these applications plays a critical role in enterprise operations, making automated testing essential to ensure business-wide continuity and software quality.
Staying up to date with Microsoft One Version
Microsoft’s One Version strategy ensures that customers of Dynamics 365 (and other connected services) run on the most up-to-date release.
The Microsoft One Version update process involves fewer but more impactful updates, with this approach providing faster access to new features, meaning that businesses need to rethink and adjust their release and testing strategies to match.
These continuous updates require a rigorous testing approach to avoid disruptions:
- Dealing with frequent, smaller updates:
- Microsoft may push out monthly, or even weekly, patches and hotfixes. Without automated testing to ensure performance stability, QA teams may risk falling behind the release cycle. And if a team falls behind one cycle, this can quickly snowball.
- Regression testing at scale:
- Every update can potentially affect your current customizations and integrations. Broad regression test coverage ensures no hidden conflicts or data integrity issues across your systems.
- Integration and E2E considerations:
- With One Version, cross-application workflows must remain functional. Even minor changes in D365 can break Power Platform or M365 flows. Testing your integrations and testing end-to-end will catch these mistakes before they compound into something much larger.
- Automation-first strategy:
- No-code test automation is essential for coping with the accelerated pace of releases. Traditional code-based scripts (e.g., Selenium) often can’t keep up with the frequent UI changes in D365, and teams end up spending hours of wasted time on repetitive tasks when they could be focusing their efforts on more important and complex cases.
Ensuring your business has the latest Microsoft innovations and critical security patches is vital for a successful application ecosystem as it provides users with more features, automation, and AI capabilities. However, this can be a resource-intensive task. Leapwork is here to help.
Software testing teams can rely on Leapwork to accelerate Microsoft update schedules and ensure all applications and application customizations work as intended. Leapwork’s platform supports multiple concurrent testing cycles at scale so that tech debt is never a threat.
