Non-Functional Testing

The reality in most testing processes today is the majority of resources and budget is spent on developing and deploying functionality, without considering how well the overall solution will work.

This can become a costly oversight that quickly leads to production outages, loss of business, user inefficiency, and security breaches. Our Non-Functional testing services deliver proven expertise to ensure non-functional elements don’t trip you up.

What is non-functional software testing?

The simple answer is that functional testing verifies what your software does, non-functional testing tells you how well it does it.

This type of testing ensures the areas that support your system’s functional aspects perform as they were designed to. It’s an activity that covers a range of different aspects including performance, usability, compatibility, accessibility, resilience, compliance and security.

Acutest Non-Functional Testing Services

Our skilled and experienced team will scope, plan, manage, and carry out all types of non-functional testing, including:

  • Performance – load, stress, soak, reliability and more
  • Operational acceptance
  • Resilience and business continuity
  • Maintainability and supportability
  • Interoperability and compatibility

We provide specialised assurance resource with security and penetration testing, accessibility testing, and readiness testing for standards certification and assessment, such as ISO, BS and EN.

Non-Functional Review

Through 20 years’ experience of working with a vast range of customers across different industry sectors, we have developed substantial insight in the defining and testing of effective non-functional requirements. As a result, we can utilise our principle-based and structured approach to quickly understand the scope and risk of your non-functional needs.

Acutest has built a comprehensive catalogue of story-based requirements, and grouped them into four themes:



including security and efficient operation



including compliance and accessibility



including patching and evergreening



including deployment and operational readiness

These themes are broken down into topics, are easily tailored to any service or application, and form a catalogue of more than 400 pre-written user stories arranged into an overarching framework. This can then be used to identify which non-functional requirements are applicable, and to speed up scoping, approach, and execution preparation.
