Test Automation 101

Getting Started with Test Automation

With more companies driving cloud transformations and upgrading to modern ERPs like Microsoft Dynamics 365, test automation has become an essential way to ensure critical business processes stay reliable and efficient.

In this guide, we break down what test automation is, why it matters for organizations using modern ERPs like Microsoft Dynamics 365, and how it helps teams move faster and with more confidence.

What Is Test Automation?

Test automation is a software testing approach where automated tools perform a set of pre-defined tests or actions on an application to quickly verify its functionality before release, minimizing the need for manual testing. In simple terms, it means using software to test software. Automated tests handle repetitive checks faster and more consistently than manual testing, freeing up your team to focus on higher-value work.

Do I Still Need Manual Testing if I Automate My Testing?

Yes. Manual and automated testing work best together. They are complementary, not replacements for each other. Automated testing is excellent for repetitive, large-scale, and business-critical validations. However, manual testing remains essential for areas where human judgment, flexibility, and creativity matter most.

As TheTestMart's Chief Product and Technical Officer, Matthew Sabath, puts it: "Automation should empower people, not replace them. When humans and automation work together, one person can do the work of many, without losing the critical insight that only people can provide."

Why Is Test Automation Important?

Updates, new features, and customizations keep your ERP system secure and competitive, but they also introduce risk. Even small changes can impact financial postings, integrations, or supply chain workflows. Automated testing helps you catch issues early before they disrupt operations or reach your end users.

Organizations that invest in automation see faster, more predictable release cycles and fewer production issues. JMP Equipment Company shared that automation helped them adopt Microsoft updates on time and improve team confidence in each deployment.

What Types of Tests Can Be Automated?

• Unit tests check that individual areas of an application work correctly on their own.
• Integration tests ensure your application connects and works properly with other systems or external services.
• End-to-end tests confirm that complete, real-world process flows (like order to cash) work as intended from start to finish.
• Performance tests ensure the system stays stable under heavy loads and peak usage.
• Regression tests check that existing features continue to work after changes or updates.

When identifying strong candidates for automation, focus on stable and predictable functionalities, repetitive and time-consuming tests, and high-risk and critical business functions where failures would cause significant operational or financial impact.

Is Test Automation Hard or Expensive to Implement?

Many organizations think automation is too complex or too costly to get started. Today, no-code tools and prebuilt test libraries make automation far more accessible and practical for organizations of all sizes. The initial investment pays off quickly by saving time, reducing the risk from updates, and avoiding operational disruptions.

As we shared in The Hidden Costs of Manual Testing, relying on manual testing alone often ends up being more expensive and disruptive than organizations expect.

Why Automated Testing Matters for Dynamics 365

Microsoft's One Version model means updates are mandatory and delivered on a set schedule. Even small changes can disrupt critical processes like financial postings, supply chain flows, and integrations if not thoroughly tested. This is why regression testing is not optional — it is a critical requirement with every update.

As Microsoft emphasizes in their official guidance on regression tooling: "You can save time and resources by automating your regression testing."
