Testing is a crucial part of every software development process as it helps to ensure that not only customer satisfaction is guaranteed, but the software itself matches all standards and requirements. While testing was traditionally limited to the functional requirements, the concept of non-functional testing has gradually come under the spotlight. Its growing importance could be attributed to the fact that modern applications and their ecosystems have both undergone drastic transformations.
The older applications usually used to run in closed, largely undistributed environments where everything was generally within control. However, the arrival and widespread utilization of cloud computing and microservices have changed the face of the applications and their ecosystems. Non-functional requirements (NFRs) have become as important as their functional counterparts, and the need and importance of testing these NFRs have consequently become equally important.
What is Non-Functional Testing?
Non-functional testing refers to the testing of those aspects of a software application which are not connected in any way with a defined user action or a function.
As the name suggests, it concentrates on an application’s non-functional aspects such as performance, usability, security, compatibility, and all other aspects that are not tested under functional testing. Non-functional testing is performed to verify these NFRs and if the system’s behavior is in accordance with them.
The following are some of the significant non-functional aspects of an application that are considered and tested under non-functional testing:
The singular purpose of NFR testing is to ensure that the application works well with regards to the non-functional aspects.
Ultimately, the motive of non-functional testing is to test all characteristics of an application that would help to provide an application which meets the business expectations.
The Importance of Non-functional Testing
Consider an application that is developed and wholly tested for functional requirements, but non-functional testing is not performed. Now imagine what would happen when the application goes live and is immediately subjected to a massive load.
In the absence of non-functional testing, you would be very unsure of the application’s ability to handle massive traffic. The application may become slow or even crash in the worst case scenario. What an embarrassment that would be! In another scenario, imagine if the application is not tested for security, if that is the case then an unauthorized party could easily crack the data entered by the app users.
Non-functional testing is as important as functional testing. It ensures security and establishes the reliability of the application. It ensures that the application developed is robust enough to work under duress. The application’s compatibility with various devices, its user-friendliness, its endurance and a host of other vital parameters are established and verified through NFR testing.
Functional vs. Non-functional Testing: What Differentiates the Two?
Though both functional and non-functional testing is performed with the objective of delivering an application in line with the demands of the business, there are many differences between the two.
A detailed analysis of functional vs non-functional testing throws up the following points as the major differentiators between the two.

According to a report, app crashes cause 71% of uninstalls.
Other reasons that compel users to uninstall apps are page response time, confusing UI, and battery consumption.
Yes, everyone has mobile phones for different purposes.
For example, if an app on our mobile phone doesn’t work rightly then, it uses too much battery life, uses more storage space, and even we don’t know what’s working until the damage does already done.In today’s environment, a performance issue with the mobile application is swiftly commencing to revenue loss, the brand of the application, and employee productivity as well.So, let me get to the blog now.

Let’s address it.Usability/User Experience - Touch:Usability is a primary quality concern for mobile apps than web or desktop.
We are not proffering priority to UI/UX testing at an early stage, so it should be tested thoroughly before building the application to overcome the cost in the future.Performance and security:When it gets to the performance and security of the application, we are testing some API and load testing with N number of users.
We can control everything on mobile apps like our bank account balance, latest cricket scores, shopping for an outfit, and finding directions to a restaurant.
A mobile app has turned out to be an effective tool or platform to bring good numbers of customers and volume of business through mobile screens.
It is turning to a scenario that the present businesses will lose their bright future without a mobile app.
Hence you should make sure that the app works as per the expectation of the customers before it is released to the app store.Mobile app testing Mobile app testing is on-demand since none of the businesses want their app to get uninstalled by the users.
The test always concentrates on the customer requirements and not goes into the details of the source code of the app.
Now, the test is made easy and accurate with the most advanced mobile app checking platforms like pCloudy.Advanced mobile app testing platform Now mobile app testing is made intelligent with platforms like pCloudy.
Now mobile app manual tests can be done on multiple devices in synchronous mode.Automated testing Manual testing is difficult when you need to test the app on several devices with different operating systems and screen resolutions.
