Automated Testing in Microsoft D365

Automated testing in Microsoft Dynamics 365 Business Central has become the gold standard for managing continuous updates, rollouts, and integrations. But as testing frameworks evolve and test coverage expands, a new challenge of testing without the right coverage has emerged, this leads to over-testing as well.

The reality is testing isn’t always productive, if coverage isn’t prioritized. When testing becomes bloated, unfocused, and resource-heavy, it drains QA capacity, slows down releases, and adds complexity rather than clarity.

Let’s talk about what misaligned test coverage looks like in Business Central environments, why it happens, and how platforms like Fortest helps teams cut through the noise and focus on what really matters.

Most Dynamics 365 Business Central teams begin with a healthy goal of reducing manual testing, increasing speed, and improving accuracy. But somewhere along the way, things often spiral into:

• Massive regression suites that take hours (or days) to execute manually
• Redundant test cases for workflows that rarely change
• Testing low-risk features with high-effort scripts
• Overlapping test ownership across business units
• Unnecessary checks triggered by minor UI or data tweaks

And due to this, it results in slower release cycles, frustrated testing teams, and decision paralysis over what actually needs to be tested after every update. Risk-based testing approaches, such as business criticality and change impact analysis, must define coverage.

This over-reliance on test volume typically stems from one key issue: a lack of clearly defined coverage objectives. Many teams react to Microsoft’s frequent updates, platform changes, hotfixes, major wave rollouts, with a blanket testing approach driven by fear of failure. Without a confident understanding of what needs coverage and why, they default to testing everything. While automation makes this possible, it doesn’t make it smart.

Other times, outdated testing strategies are to blame. Legacy manual test cases are often lifted directly into automation frameworks without re-evaluation, leading to unnecessary or irrelevant tests that add little value. In many cases, teams focus on what can be automated instead of what should be automated. This misalignment leads to gaps in critical areas and redundancy elsewhere.

This approach can lead to gaps in end-to-end coverage where individual components are tested in isolation, but the full business process isn’t validated as a whole. In complex systems like Dynamics 365 Business Central, an end-to-end perspective is essential to catch integration issues, data flow problems, and real-world user scenarios that only emerge when the system is exercised holistically.

Without proper end-to-end coverage, you may have hundreds of passing tests and still miss failures that happen where processes intersect.

While testing is supposed to accelerate change, if testing coverage isn’t defined, over-testing would occur introducing friction and increasing cost:

• Wasted time and effort: Testing teams spend hours maintaining tests that rarely catch critical bugs.
• Delayed releases: Excessive test cycles extend timelines and bottleneck DevOps pipelines.
• Increased maintenance overhead: More tests mean more points of failure when configurations or integrations shift.
• Team burnout: Repetitive cycles and unclear test value drain morale and productivity.
