Non-Functional Testing: What is the Significance?

There are different types of testing and if you are an app developer, you may already know about them. Of course, if you are venturing into the world of developing then you must acquaint yourself with the different types of testing.

Now talking about a significant type of testing known as non functional testing, it is very crucial for your procedures. This is the testing that verifies how applications work by evaluating things such as performance, accessibility, and even that of UX.

Difference Between Functional and Non-functional type of Testing

The common difference between functional and nonfunctional type of testing is what they test. Functional testing makes sure that functions and features of the application act properly. Nonfunctional type of testing evaluates other aspects of how proper the application works.

Functional testing examines the functionality of an app. Nonfunctional type of testing examines the performance of these functions. A few of the examples of functional testing encompass unit testing, API testing, integration testing, exploratory testing, and critical business flows testing, these all examine the functional aspects of both the website or mobile application.

Why You require Nonfunctional type of Testing?

Nonfunctional type of testing is just as crucial as functional testing. And because teams require to conduct a mix of diverse types of testing, you need to be doing both. You know, nonfunctional type of testing makes applications a lot more usable and more dependable. Unfortunately, it may often be rushed to fulfil the release deadlines.

Once nonfunctional testing gets overlooked, performance and UX defects may leave users with a bad experience and trigger the brand damage. Worse, applications could even crash with an influx of users. Accessibility defects may end up in compliance fines. And their security could even be at risk.

Some of the Nonfunctional types of Testing

Nonfunctional type of testing is an umbrella term. There are various nonfunctional kind of testing types. Have a look at some here:

  • Accessibility testing — Tests how usable and effective the app is to users with different disabilities, like vision impairment.
  • Availability testing — examines how often the app gets accessible and readily available for use.
  • Compliance testing — examines whether an app fulfils specified requirements or regulations.
  • Configuration testing — Examines an app against software and hardware differences.
  • Disaster recovery testing — Examines the recovery of business-critical applications in emergency conditions.
  • Endurance testing — it is something that examines an app under a heavy load over a really extended period.
  • Failover testing — Examines an app’s backup system in the time of a system failure. 
  • Geolocation testing — Test’s location-based the scenarios on an application .
  • Internationalization testing — examines if an application can familiarize to regional languages and other factors based on location.
  • Load testing — Examines an app’s performance under peak conditions.
  • Maintainability testing — examines the app’s capability to update.
  • Performance testing — examines the speed and responsiveness of an app under diverse  conditions.
  • Portability testing — it is something that tests how an app transfers from one software or operational environment to that of another.
  • Resilience testing — examines an app’s ability to perform under extremely stressed conditions.
  • Security testing — examines an app’s security mechanisms to reveal susceptibilities.
  • Scalability testing — examines an app’s ability to scale up or down as user requests differ.
  • Stress testing — Examines an app’s stability under heavy loads or that of extreme conditions.
  • Usability testing — examines an app’s ease of use.
