Non-Functional Software Testing Services

Don’t underestimate the importance of non-functional software requirements — test your software solution from A to Z with our QA expertise.

Non-functional software testing

There is no denying the fact that the functional requirements of a software product are important. After all, the functionality of the app and its ability to actually do what it’s supposed to do are what attracts the users in the first place. This is why functional testing is often the first stage of QA for a new software solution.

However, the non-functional requirements of an app should be treated with the same level of attention and precision. Non-functional testing is designed not just to verify the fact that a software product works, but to see how exactly it does it. From testing the load capabilities and performance metrics of an app to checking compatibility, security, and localization of the product, there are countless non-functional software testing types that deal with every non-functional aspect of a product.

It’s impossible to say which types of non-functional testing services are more important than the others. When you have a brand new or a recently updated software solution and you want to get the most complete idea of its current state, but don’t know which types of testing your project needs, all you have to do is trust our QA expertise. We have spent the past two decades performing every type of non-functional software testing you can imagine. So we know exactly what your product needs to remain secure and stable, and to appeal to the right kind of users.

Non-functional testing results

  • Competitive edge
    In this day and age, the software market is highly saturated with cutting-edge solutions and attractive offers. As a product owner, you need to use every advantage you can get. And when there are already several products with the same functionality as your solution, then swift performance, uncompromised security, and appealing UI can become the one competitive advantage you are looking for.
  • Easy scalability
    Strategic thinking means taking care not only of the product’s immediate success, but also planning the steps to your subsequent business expansion. When every non-functional component of your software product works exactly like you envisioned, scalability becomes a far easier challenge than you originally thought. So you can take care of the matters at hand and maintain confidence in your solution.
  • Audience recognition
    User recognition is a valuable asset to have these days. A loyal audience will follow a software product no matter which direction it may take. However, user recognition does not appear out of the blue, and the non-functional aspects of your software solution have a huge influence on how your product is received by the audience. Users are not going to stick with a buggy, unappealing app or site.
  • One less thing to worry about
    When developing a software product that is intended for a wide audience, you have dozens of things to work on if you want to achieve success and recognition. From branding and functionality to marketing, every software product owner has enough on their plate as it is, so you don’t need to add worrying about the non-functional issues to the mix. Entrust us with non-functional testing and sleep better at night.
