Regulated systems need more automation, not less

Critical systems are now deeply interconnected, spanning legacy infrastructure, cloud services, third-party providers and vast volumes of sensitive data. A change in one part of the environment can have unintended consequences elsewhere, and a missed defect in a payment workflow, claims process or customer onboarding journey can quickly become an operational, financial or regulatory problem.

Testing must therefore provide more than a final quality check. It must give organisations the confidence to keep changing complex systems without compromising the controls around them. Yet as manual regression cycles become longer and harder to scale, releases slow down, coverage becomes inconsistent and teams grow hesitant to make necessary changes.

Automation is often perceived as a threat to oversight. Implemented correctly, it provides the consistency, traceability and evidence that regulated organisations need.

“There is a perception that test automation reduces oversight or makes compliance harder to manage,” says Akshay Deole, head of testing at custom software solutions provider BBD. “In reality, the opposite is true.”

The more complex a system becomes, the harder it is to check manually that a new change has not disrupted something that was already working. Testing teams face growing numbers of integrations, dependencies and business rules, often under pressure to complete regression cycles within shrinking delivery windows.

Repetitive testing also creates room for inconsistency. Scenarios may be interpreted differently, evidence captured unevenly or lower-priority tests dropped when time runs out. In a regulated environment, those gaps matter.

Automated regression testing changes the equation by repeatedly validating the workflows where failure would have the greatest impact: payment processing, identity verification, claims validation, customer onboarding, access management or telecoms billing.

That does not mean automating every possible test. Attempting to do so often produces an expensive, unwieldy framework that teams struggle to maintain. The strongest strategies start with the processes that carry the greatest business and regulatory risk.

“Complexity is not a reason to avoid automation,” says Deole. “It is the reason automation becomes necessary.”

Speed alone is not enough. Regulated organisations must also be able to show what was tested, which requirement it related to, what the result was and whether the correct controls were followed.

When traceability is built into an automation framework, every execution creates its own evidence. Test assets are version controlled, results are logged and reporting becomes a continuous part of delivery rather than a scramble to reconstruct the record afterwards.

That is a more consistent audit trail than a collection of manually maintained spreadsheets, screenshots and disconnected testing artefacts. It also gives engineering, testing, compliance and business teams a clearer, shared view of whether a system is behaving as expected.

Automation does not remove governance from the process.
